lies of his bones are coral made those are pearls that were his eyes nothing of him that doth fade but doth suffer a sea change into something rich and strange all the world is a stage and all the men and women merely players they have their exits and their entrances and one man in his time plays many parts his acts being seven ages at first the infant mewling and puking in the nurses arms and then the whining schoolboy with his satchel and shining morning face creeping like snail unwillingly to school and then the lover sighing like furnace with a woeful ballad made to his mistress eyebrow then a soldier full of strange oaths and bearded like the pard jealous in honour sudden and quick in quarrel seeking the bubble reputation even in the cannons mouth and then the justice in fair round belly with good capon lined with eyes severe and beard of formal cut full of wise saws and modern instances and so he plays his part the sixth age shifts into the lean and slippered pantaloon with spectacles on nose and pouch on side his youthful hose well saved a world too wide for his shrunk shank and his big manly voice turning again toward childish treble pipes and whistles in his sound last scene of all that ends this strange eventful history is second childishness and mere oblivion sans teeth sans eyes sans taste sans everything now is the winter of our discontent made glorious summer by this son of york and all the clouds that loured upon our house in the deep bosom of the ocean buried now are our brows bound with victorious wreaths our bruised arms hung up for monuments our stern alarums changed to merry meetings our dreadful marches to delightful measures grim visaged war hath smoothed his wrinkled front and now instead of mounting barbed steeds to fright the souls of fearful adversaries he capers nimbly in a ladys chamber to the lascivious pleasing of a lute but i that am not shaped for sportive tricks nor made to court an amorous looking glass i that am rudely stamped and want loves majesty to strut before a nymphing walking spirit i that am curtailed of this fair proportion cheated of feature by dissembling nature deformed unfinished sent before my time into this breathing world scarce half made up and that so lamely and unfashionable that dogs bark at me as i halt by them why i in this weak piping time of peace have no delight to pass away the time unless to spy my shadow in the sun and descant on mine own deformity if music be the food of love play on give me excess of it that surfeiting the appetite may sicken and so die that strain again it had a dying fall oh it came over my ear like the sweet sound that breathes upon a bank of violets stealing and giving odour enough no more tis not so sweet now as it was before oh spirit of love how quick and fresh art thou that notwithstanding thy capacity receiveth as the sea nought enters there of what validity and pitch so ever but falls into abatement and low price even in a minute so full of shapes is fancy that it alone is high fantastical the quality of mercy is not strained it droppeth as the gentle rain from heaven upon the place beneath it is twice blessed it blesseth him that gives and him that takes tis mightiest in the mightiest it becomes the throned monarch better than his crown his sceptre shows the force of temporal power the attribute to awe and majesty wherein doth sit the dread and fear of kings but mercy is above this sceptred sway it is enthroned in the hearts of kings it is an attribute to god himself and earthly power doth then show likest gods when mercy seasons justice therefore jew though justice be thy plea consider this that in the course of justice none of us should see salvation we do pray for mercy and that same prayer doth teach us all to render the deeds of mercy friends romans countrymen lend me your ears i come to bury caesar not to praise him the evil that men do lives after them the good is oft interred with their bones so let it be with caesar the noble brutus hath told you caesar was ambitious if it were so it was a grievous fault and grievously hath caesar answered it here under leave of brutus and the rest for brutus is an honourable man so are they all all honourable men come i to speak in caesars funeral he was my friend faithful and just to me but brutus says he was ambitious and brutus is an honourable man he hath brought many captives home to rome whose ransoms did the general coffers fill did this in caesar seem ambitious when that the poor have cried caesar hath wept ambition should be made of sterner stuff yet brutus says he was ambitious and brutus is an honourable man you all did see that on the lupercal i thrice presented him a kingly crown which he did thrice refuse was this ambition yet brutus says he was ambitious and sure he is an honourable man i speak not to disprove what brutus spoke but here i am to speak what i do know you all did love him once not without cause what cause withholds you then to mourn for him oh judgment thou art fled to brutish beasts and men have lost their reason bear with me my heart is in the coffin there with caesar and i must pause till it come back to me double double toil and trouble fire burn and cauldron bubble fillet of a fenny snake in the cauldron boil and bake eye of newt and toe of frog wool of bat and tongue of dog adders fork and blind worms sting lizards leg and owlets wing for a charm of powerful trouble like a hell broth boil and bubble by the pricking of my thumbs something wicked this way comes open locks whoever knocks how now you secret black and midnight hags what is it you do a deed without a name i conjure you by that which you profess however you come to know it answer me though you untie the winds and let them fight against the churches though the yeasty waves confound and swallow navigation up though bladed corn be lodged and trees blown down though castles topple on their warders heads though palaces and pyramids do slope their heads to their foundations though the treasure of natures germains tumble all together even till destruction sicken answer me to what i ask you speak demand we will answer first witch second witch third witch all say on if you had rather hear it from our mouths or from our masters pour in sows blood that hath eaten her nine farrow grease thats sweaten from the murderers gibbet throw into the flame come high or low thyself and office deftly show if we shadows have offended think but this and all is mended that you have but slumbered here while these visions did appear and this weak and idle theme no more yielding but a dream gentles do not reprehend if you pardon we will mend and as i am an honest puck if we have unearned luck now to scape the serpents tongue we will make amends ere long else the puck a liar call so good night unto you all give me your hands if we be friends and robin shall restore amends o what a rogue and peasant slave am i is it not monstrous that this player here but in a fiction in a dream of passion could force his soul so to his own conceit that from her working all his visage wanned tears in his eyes distraction in his aspect a broken voice and his whole function suiting with forms to his conceit and all for nothing for hecuba what is hecuba to him or he to hecuba that he should weep for her what would he do had he the motive and the cue for passion that i have he would drown the stage with tears and cleave the general ear with horrid speech make mad the guilty and appal the free confound the ignorant and amaze indeed the very faculties of eyes and ears yet i a dull and muddy mettled rascal peak like john a dreams unpregnant of my cause and can say nothing no not for a king upon whose property and most dear life a damned defeat was made am i a coward who calls me villain breaks my pate across plucks off my beard and blows it in my face tweaks me by the nose gives me the lie in the throat as deep as to the lungs who does me this ha swounds i should take it for it cannot be but i am pigeon livered and lack gall to make oppression bitter or ere this i should have fatted all the region kites with this slaves offal bloody bawdy villain remorseless treacherous lecherous kindless villain oh vengeance why what an ass am i this is most brave that i the son of a dear father murdered prompted to my revenge by heaven and hell must like a whore unpack my heart with words and fall a cursing like a very drab a scullion fie upon it foh about my brain i have heard that guilty creatures sitting at a play have by the very cunning of the scene been struck so to the soul that presently they have proclaimed their malefactions for murder though it have no tongue will speak with most miraculous organ i will have these players play something like the murder of my father before mine uncle i will observe his looks i will tent him to the quick if he but blench i know my course the spirit that i have seen may be the devil and the devil hath power to assume a pleasing shape yea and perhaps out of my weakness and my melancholy as he is very potent with such spirits abuses me to damn me i will have grounds more relative than this the plays the thing wherein i will catch the conscience of the king speak the speech i pray you as i pronounced it to you trippingly on the tongue but if you mouth it as many of your players do i had as lief the town crier spoke my lines nor do not saw the air too much with your hand thus but use all gently for in the very torrent tempest and as i may say the whirlwind of passion you must acquire and beget a temperance that may give it smoothness oh it offends me to the soul to hear a robustious periwig pated fellow tear a passion to tatters to very rags to split the ears of the groundlings who for the most part are capable of nothing but inexplicable dumb shows and noise i would have such a fellow whipped for overdoing termagant it out herods herod pray you avoid it be not too tame neither but let your own discretion be your tutor suit the action to the word the word to the action with this special observance that you overstep not the modesty of nature for anything so overdone is from the purpose of playing whose end both at the first and now was and is to hold as twere the mirror up to nature to show virtue her own feature scorn her own image and the very age and body of the time his form and pressure now this overdone or come tardy off though it make the unskilful laugh cannot but make the judicious grieve the censure of the which one must in your allowance overweigh a whole theatre of others oh there be players that i have seen play and heard others praise and that highly not to speak it profanely that neither having the accent of christians nor the gait of christian pagan nor man have so strutted and bellowed that i have thought some of natures journeymen had made men and not made them well they imitated humanity so abominably oh reform it altogether and let those that play your clowns speak no more than is set down for them for there be of them that will themselves laugh to set on some quantity of barren spectators to laugh too though in the mean time some necessary question of the play be then to be considered that is villanous and shows a most pitiful ambition in the fool that uses it go make you ready how all occasions do inform against me and spur my dull revenge what is a man if his chief good and market of his time be but to sleep and feed a beast no more sure he that made us with such large discourse looking before and after gave us not that capability and godlike reason to fust in us unused now whether it be bestial oblivion or some craven scruple of thinking too precisely on the event a thought which quartered hath but one part wisdom and ever three parts coward i do not know why yet i live to say this things to do since i have cause and will and strength and means to do it examples gross as earth exhort me witness this army of such mass and charge led by a delicate and tender prince whose spirit with divine ambition puffed makes mouths at the invisible event exposing what is mortal and unsure to all that fortune death and danger dare even for an eggshell rightly to be great is not to stir without great argument but greatly to find quarrel in a straw when honours at the stake how stand i then that have a father killed a mother stained excitements of my reason and my blood and let all sleep while to my shame i see the imminent death of twenty thousand men that for a fantasy and trick of fame go to their graves like beds fight for a plot whereon the numbers cannot try the cause which is not tomb enough and continent to hide the slain oh from this time forth my thoughts be bloody or be nothing worth when that i was and a little tiny boy with hey ho the wind and the rain a foolish thing was but a toy for the rain it raineth every day but when i came to mans estate with hey ho the wind and the rain gainst knaves and thieves men shut their gate for the rain it raineth every day but when i came alas to wive with hey ho the wind and the rain by swaggering could i never thrive for the rain it raineth every day but when i came unto my beds with hey ho the wind and the rain with tosspots still had drunken heads for the rain it raineth every day a great while ago the world begun with hey ho the wind and the rain but thats all one our play is done and we will strive to please you every day let me not to the marriage of true minds admit impediments love is not love which alters when it alteration finds or bends with the remover to remove oh no it is an ever fixed mark that looks on tempests and is never shaken it is the star to every wandering bark whose worths unknown although his height be taken loves not times fool though rosy lips and cheeks within his bending sickles compass come love alters not with his brief hours and weeks but bears it out even to the edge of doom if this be error and upon me proved i never writ nor no man ever loved when in disgrace with fortune and mens eyes i all alone beweep my outcast state and trouble deaf heaven with my bootless cries and look upon myself and curse my fate wishing me like to one more rich in hope featured like him like him with friends possessed desiring this mans art and that mans scope with what i most enjoy contented least yet in these thoughts myself almost despising haply i think on thee and then my state like to the lark at break of day arising from sullen earth sings hymns at heavens gate for thy sweet love remembered such wealth brings that then i scorn to change my state with kings when to the sessions of sweet silent thought i summon up remembrance of things past i sigh the lack of many a thing i sought and with old woes new wail my dear times waste then can i drown an eye unused to flow for precious friends hid in deaths dateless night and weep afresh loves long since cancelled woe and moan the expense of many a vanished sight then can i grieve at grievances foregone and heavily from woe to woe tell over the sad account of fore bemoaned moan which i new pay as if not paid before but if the while i think on thee dear friend all losses are restored and sorrows end that time of year thou mayst in me behold when yellow leaves or none or few do hang upon those boughs which shake against the cold bare ruined choirs where late the sweet birds sang in me thou seest the twilight of such day as after sunset fadeth in the west which by and by black night doth take away deaths second self that seals up all in rest in me thou seest the glowing of such fire that on the ashes of his youth doth lie as the deathbed whereon it must expire consumed with that which it was nourished by this thou perceivest which makes thy love more strong to love that well which thou must leave ere long my mistress eyes are nothing like the sun coral is far more red than her lips red if snow be white why then her breasts are dun if hairs be wires black wires grow on her head i have seen roses damasked red and white but no such roses see i in her cheeks and in some perfumes is there more delight than in the breath that from my mistress reeks i love to hear her speak yet well i know that music hath a far more pleasing sound i grant i never saw a goddess go my mistress when she walks treads on the ground and yet by heaven i think my love as rare as any she belied with false compare shall i hear more or shall i speak at this o romeo romeo wherefore art thou romeo deny thy father and refuse thy name or if thou wilt not be but sworn my love and i will no longer be a capulet tis but thy name that is my enemy thou art thyself though not a montague what is montague it is nor hand nor foot nor arm nor face nor any other part belonging to a man oh be some other name what is in a name that which we call a rose by any other name would smell as sweet so romeo would were he not romeo called retain that dear perfection which he owes without that title romeo doff thy name and for that name which is no part of thee take all myself how camest thou hither tell me and wherefore the orchard walls are high and hard to climb and the place death considering who thou art if any of my kinsmen find thee here with loves light wings did i overperch these walls for stony limits cannot hold love out and what love can do that dares love attempt therefore thy kinsmen are no let to me if they do see thee they will murder thee alack there lies more peril in thine eye than twenty of their swords look thou but sweet and i am proof against their enmity i would not for the world they saw thee here i have nights cloak to hide me from their sight and but thou love me let them find me here my life were better ended by their hate than death prorogued wanting of thy love by whose direction foundst thou out this place by love who first did prompt me to inquire he lent me counsel and i lent him eyes i am no pilot yet wert thou as far as that vast shore washed with the farthest sea i would adventure for such merchandise dost thou love me i know thou wilt say ay and i will take thy word yet if thou swearest thou mayst prove false at lovers perjuries they say jove laughs oh gentle romeo if thou dost love pronounce it faithfully or if thou thinkest i am too quickly won i will frown and be perverse and say thee nay so thou wilt woo but else not for the world in truth fair montague i am too fond and therefore thou mayst think my behaviour light but trust me gentleman i will prove more true than those that have more cunning to be strange i should have been more strange i must confess but that thou overheardst ere i was ware my true love passion therefore pardon me and not impute this yielding to light love which the dark night hath so discovered lady by yonder blessed moon i swear that tips with silver all these fruit tree tops oh swear not by the moon the inconstant moon that monthly changes in her circled orb lest that thy love prove likewise variable what shall i swear by do not swear at all or if thou wilt swear by thy gracious self which is the god of my idolatry and i will believe thee well do not swear although i joy in thee i have no joy of this contract tonight it is too rash too unadvised too sudden too like the lightning which doth cease to be ere one can say it lightens sweet good night this bud of love by summers ripening breath may prove a beauteous flower when next we meet good night good night a thousand times good night nay from the orchard side look there your lord and master is approaching what a piece of work is a man how noble in reason how infinite in faculty in form and moving how express and admirable in action how like an angel in apprehension how like a god the beauty of the world the paragon of animals and yet to me what is this quintessence of dust man delights not me no nor woman neither though by your smiling you seem to say so my lord we think not so what then you are merry the world is grown so bad that wrens make prey where eagles dare not perch since every jack became a gentleman there is many a gentle person made a jack now by saint paul i swear i will not dine until i see the same and from my soul i love thy daughter and do intend to make her queen my gracious sovereign as i ride along i thought upon the words which your grace spoke to me and shall recount them over again the duke of buckingham shall pay for this my lord what treachery was used the tender prince was by his nurses counsel sent to learn what trick the world has and by good soul was never none to him that trusted first the wolf doth grin before he barketh a plague upon it when thieves cannot be true one to another diff --git a/src/storm/experience_engine.zig.bak2 b/src/storm/experience_engine.zig.bak2 deleted file mode 100644 index b2c8f8099c..0000000000 ---

UPDATES: last updated - 10 march 2020 (v1.0.1) +* v1.0.1 - Made it work with latest raygui version +* - Added `GuiDMSaveProperties()` for saving properties to a text file +* - A `GuiDMLoadProperties()` is planed but not implemented yet +* - Added a section property that can work as a way to group multiple properties +* - Fixed issue with section not having the correct height +* v1.0.0 - Initial release +* +* +* MODULE USAGE: +* #define GUI_PROPERTY_LIST_IMPLEMENTATION +* #include "dm_property_list.h" +* +* INIT: GuiDMProperty props[] = { // initialize a set of properties

v4.5-dev - A simple and easy-to-use immediate-mode gui library +* +* DESCRIPTION: +* raygui is a tools-dev-focused immediate-mode-gui library based on raylib but also +* available as a standalone library, as long as input and drawing functions are provided +* +* FEATURES: +* - Immediate-mode gui, minimal retained data +* - +25 controls provided (basic and advanced) +* - Styling system for colors, font and metrics +* - Icons supported, embedded as a 1-bit icons pack +* - Standalone mode option (custom input/graphics backend) +* - Multiple support tools provided for raygui development +* +* POSSIBLE IMPROVEMENTS: +* - Better standalone mode API for easy plug of custom backends +* - Externalize required inputs, allow user easier customization +* +* LIMITATIONS: +* - No editable multi-line word-wraped text box supported +* - No auto-layout mechanism, up to the user to define controls position and size +* - Standalone mode requires library modification and some user work to plug another backend +* +* NOTES: +* - WARNING: GuiLoadStyle() and GuiLoadStyle{Custom}() functions, allocate memory for +* font atlas recs and glyphs, freeing that memory is (usually) up to the user, +* no unload function is explicitly provided... but note that GuiLoadStyleDefault() unloads +* by default any previously loaded font (texture, recs, glyphs) +* - Global UI alpha (guiAlpha) is applied inside GuiDrawRectangle() and GuiDrawText() functions +* +* CONTROLS PROVIDED: +* # Container/separators Controls +* - WindowBox --> StatusBar, Panel +* - GroupBox --> Line +* - Line +* - Panel --> StatusBar +* - ScrollPanel --> StatusBar +* - TabBar --> Button +* +* # Basic Controls +* - Label +* - LabelButton --> Label +* - Button +* - Toggle +* - ToggleGroup --> Toggle +* - ToggleSlider +* - CheckBox +* - ComboBox +* - DropdownBox +* - TextBox +* - ValueBox --> TextBox +* - Spinner --> Button, ValueBox +* - Slider +* - SliderBar --> Slider +* - ProgressBar +* - StatusBar +* - DummyRec +* - Grid +* +* # Advance Controls +* - ListView +* - ColorPicker --> ColorPanel, ColorBarHue +* - MessageBox --> Window, Label, Button +* - TextInputBox --> Window, Label, TextBox, Button +* +* It also provides a set of functions for styling the controls based on its properties (size, color) +* +* +* RAYGUI STYLE (guiStyle): +* raygui uses a global data array for all gui style properties (allocated on data segment by default), +* when a new style is loaded, it is loaded over the global style... but a default gui style could always be +* recovered with GuiLoadStyleDefault() function, that overwrites the current style to the default one +* +* The global style array size is fixed and depends on the number of controls and properties: +* +* static unsigned int guiStyle[RAYGUI_MAX_CONTROLS*(RAYGUI_MAX_PROPS_BASE + RAYGUI_MAX_PROPS_EXTENDED)]; +* +* guiStyle size is by default: 16*(16 + 8) = 384*4 = 1536 bytes = 1.5 KB +* +* Note that the first set of BASE properties (by default guiStyle[0..15]) belong to the generic style +* used for all controls, when any of those base values is set, it is automatically populated to all +* controls, so, specific control values overwriting generic style should be set after base values +* +* After the first BASE set we have the EXTENDED properties (by default guiStyle[16..23]), those +* properties are actually common to all controls and can not be overwritten individually (like BASE ones) +* Some of those properties are: TEXT_SIZE, TEXT_SPACING, LINE_COLOR, BACKGROUND_COLOR +* +* Custom control properties can be defined using the EXTENDED properties for each independent control. +* +* TOOL: rGuiStyler is a visual tool to customize raygui style: github.com/raysan5/rguistyler +* +* +* RAYGUI ICONS (guiIcons): +* raygui could use a global array containing icons data (allocated on data segment by default), +* a custom icons set could be loaded over this array using GuiLoadIcons(), but loaded icons set +* must be same RAYGUI_ICON_SIZE and no more than RAYGUI_ICON_MAX_ICONS will be loaded +* +* Every icon is codified in binary form, using 1 bit per pixel, so, every 16x16 icon +* requires 8 integers (16*16/32) to be stored in memory. +* +* When the icon is draw, actually one quad per pixel is drawn if the bit for that pixel is set +* +* The global icons array size is fixed and depends on the number of icons and size: +* +* static unsigned int guiIcons[RAYGUI_ICON_MAX_ICONS*RAYGUI_ICON_DATA_ELEMENTS]; +* +* guiIcons size is by default: 256*(16*16/32) = 2048*4 = 8192 bytes = 8 KB +* +* TOOL: rGuiIcons is a visual tool to customize/create raygui icons: github.com/raysan5/rguiicons +* +* RAYGUI LAYOUT: +* raygui currently does not provide an auto-layout mechanism like other libraries, +* layouts must be defined manually on controls drawing, providing the right bounds Rectangle for it +* +* TOOL: rGuiLayout is a visual tool to create raygui layouts: github.com/raysan5/rguilayout +* +* CONFIGURATION: +* #define RAYGUI_IMPLEMENTATION +* Generates the implementation of the library into the included file +* If not defined, the library is in header only mode and can be included in other headers +* or source files without problems. But only ONE file should hold the implementation +* +* #define RAYGUI_STANDALONE +* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined +* internally in the library and input management and drawing functions must be provided by +* the user (check library implementation for further details) +* +* #define RAYGUI_NO_ICONS +* Avoid including embedded ricons data (256 icons, 16x16 pixels, 1-bit per pixel, 2KB) +* +* #define RAYGUI_CUSTOM_ICONS +* Includes custom ricons.h header defining a set of custom icons, +* this file can be generated using rGuiIcons tool +* +* #define RAYGUI_DEBUG_RECS_BOUNDS +* Draw control bounds rectangles for debug +* +* #define RAYGUI_DEBUG_TEXT_BOUNDS +* Draw

+――――――――――――――――――――――――――――――― +Thanks for Downloading Homespun. + +Homespun TT [.ttf] +Homespun [8pt] [.fon] + + + 'homespun.fon' is a Windows Bitmap Font (.fon). This font is best +used at 8pt. To use it at larger point sizes (for images), try using +a graphics program like Photoshop, Paint Shop Pro, or the Paint +program that comes with Windows. Type out your text at the recommended +point size [8pt], then resize the image. Set the color mode to 256 +or 2 colors so the edges don't get blured when resizing, then after you +have the text to the size that you want, then change back to a higher +color mode and edit the image. + + For programs that don't show Bitmap Fonts in the Font Selector, you +may be able to get the font to work by typing in: +homespun brk + + When using the TTF version, try using it with anti-aliasing off. + + +If you have any questions or comments, you can e-mail me at +kentpw@norwich.net + +You can visit my Webpage <ΖNIGMA GAMES & FONTS> at +http://www.aenigmafonts.com/ + +________________ +INSTALLING FONTS +―――――――――――――――― + There's a couple of ways to install Fonts. The 'easy' way to +install fonts is to just Unzip/place the font file [.ttf] into your +Windows\Fonts directory (I always use this method). If you're unable +to do it the 'easy' way, then try to do it this way (for Windows +95/98/NT): + +1] Unzip the Font(s) to a folder (or somewhere, just remember where +you unzipped it) on your Computer. + +2] Next, click on the START button, then select SETTINGS then +CONTROL PANEL. + +3] When the Control Panel Window pops up, Double Click on FONTS. + +4] When the FONTS window pops up, select File then Install New Font... + +5] A Add Fonts window will pop up, just go to the folder that you +unzipped the Font(s) to, select the Font(s) and then click on OK. +Now the Font(s) are installed. + + Now you can use the Font(s) in programs that utilize Fonts. Make +sure that you install the font(s) first, then open up your apps +(so the app will recognize the font). Sometimes you'll have to +wait until your computer 'auto-refreshes' for programs to recognize +fonts (Windows is sometimes slow to do that). You can refresh your +computer quicker by going into Windows Explorer -or- My Computer and +press F5 (or in the menubar select VIEW then REFRESH). + + +__________ +DISCLAIMER +―――――――――― +-The font(s) in this zip file were created by me (Brian Kent). All +of my Fonts are Freeware, you can use them any way you want to +(Personal use, Commercial use, or whatever). + +-If you have a Font related site and would like to offer my fonts on +your site, go right ahead. All I ask is that you keep this text file +intact with the Font. + +-You may not Sell or Distribute my Fonts for profit or alter them in +any way without asking me first.

A Trie (prefix tree) data structure for efficient string storage and retrieval. +//! +//! Tries are tree structures where each node represents a character in a string.

Follow below template structure, example info should list the module, the short description + and the author of the example, twitter or github info could be also provided for the author + Short description should also be used on the title of the window + + 3. Code should be organized by sections:[Initialization]- [Update] - [Draw] - [De-Initialization] + Place your code between the dotted lines for every section, please don't mix update logic with drawing + and remember to unload all loaded resources + + 4. Code should follow raylib conventions: https://github.com/raysan5/raylib/wiki/raylib-coding-conventions + Try to be very organized, using line-breaks appropiately + + 5. Add comments to the specific parts of code the example is focus on + Don't abuse with comments, try to be clear and impersonal on the comments + + 6. Try to keep the example simple, under 300 code lines if possible. Try to avoid external dependencies + Try to avoid defining functions outside the main(). Example should be as self-contained as possible + + 7. About external resources, they should be placed in a [resources] folder and those resources + should be open and free for use and distribution.

+* +* guiStyle size is by default: 16*(16 + 8) = 384*4 = 1536 bytes = 1.5 KB +* +* Note that the first set of BASE properties (by default guiStyle[0..15]) belong to the generic style +* used for all controls, when any of those base values is set, it is automatically populated to all +* controls, so, specific control values overwriting generic style should be set after base values. +* +* After the first BASE set we have the EXTENDED properties (by default guiStyle[16..23]), those +* properties are actually common to all controls and can not be overwritten individually (like BASE ones) +* Some of those properties are: TEXT_SIZE, TEXT_SPACING, LINE_COLOR, BACKGROUND_COLOR +* +* Custom control properties can be defined using the EXTENDED properties for each independent control. +* +* TOOL: rGuiStyler is a visual tool to customize raygui style: github.com/raysan5/rguistyler +* +* +* RAYGUI ICONS (guiIcons): +* raygui could use a global array containing icons data (allocated on data segment by default), +* a custom icons set could be loaded over this array using GuiLoadIcons(), but loaded icons set +* must be same RAYGUI_ICON_SIZE and no more than RAYGUI_ICON_MAX_ICONS will be loaded +* +* Every icon is codified in binary form, using 1 bit per pixel, so, every 16x16 icon +* requires 8 integers (16*16/32) to be stored in memory. +* +* When the icon is draw, actually one quad per pixel is drawn if the bit for that pixel is set. +* +* The global icons array size is fixed and depends on the number of icons and size: +* +* static unsigned int guiIcons[RAYGUI_ICON_MAX_ICONS*RAYGUI_ICON_DATA_ELEMENTS]; +* +* guiIcons size is by default: 256*(16*16/32) = 2048*4 = 8192 bytes = 8 KB +* +* TOOL: rGuiIcons is a visual tool to customize/create raygui icons: github.com/raysan5/rguiicons +* +* RAYGUI LAYOUT: +* raygui currently does not provide an auto-layout mechanism like other libraries, +* layouts must be defined manually on controls drawing, providing the right bounds Rectangle for it. +* +* TOOL: rGuiLayout is a visual tool to create raygui layouts: github.com/raysan5/rguilayout +* +* CONFIGURATION: +* #define RAYGUI_IMPLEMENTATION +* Generates the implementation of the library into the included file. +* If not defined, the library is in header only mode and can be included in other headers +* or source files without problems.

Have exactly one source file where you define + * `CGLTF_IMPLEMENTATION` before including this file to get the + * function definitions. + * + * Reference: + * `cgltf_result cgltf_parse(const cgltf_options*, const void*, + * cgltf_size, cgltf_data**)` parses both glTF and GLB data. If + * this function returns `cgltf_result_success`, you have to call + * `cgltf_free()` on the created `cgltf_data*` variable. + * Note that contents of external files for buffers and images are not + * automatically loaded. You'll need to read these files yourself using + * URIs in the `cgltf_data` structure. + * + * `cgltf_options` is the struct passed to `cgltf_parse()` to control + * parts of the parsing process. You can use it to force the file type + * and provide memory allocation as well as file operation callbacks. + * Should be zero-initialized to trigger default behavior. + * + * `cgltf_data` is the struct allocated and filled by `cgltf_parse()`. + * It generally mirrors the glTF format as described by the spec (see + * https://github.com/KhronosGroup/glTF/tree/master/specification/2.0). + * + * `void cgltf_free(cgltf_data*)` frees the allocated `cgltf_data` + * variable. + * + * `cgltf_result cgltf_load_buffers(const cgltf_options*, cgltf_data*, + * const char* gltf_path)` can be optionally called to open and read buffer + * files using the `FILE*` APIs. The `gltf_path` argument is the path to + * the original glTF file, which allows the parser to resolve the path to + * buffer files. + * + * `cgltf_result cgltf_load_buffer_base64(const cgltf_options* options, + * cgltf_size size, const char* base64, void** out_data)` decodes + * base64-encoded data content. Used internally by `cgltf_load_buffers()`. + * This is useful when decoding data URIs in images. + * + * `cgltf_result cgltf_parse_file(const cgltf_options* options, const + * char* path, cgltf_data** out_data)` can be used to open the given + * file using `FILE*` APIs and parse the data using `cgltf_parse()`. + * + * `cgltf_result cgltf_validate(cgltf_data*)` can be used to do additional + * checks to make sure the parsed glTF data is valid. + * + * `cgltf_node_transform_local` converts the translation / rotation / scale properties of a node + * into a mat4. + * + * `cgltf_node_transform_world` calls `cgltf_node_transform_local` on every ancestor in order + * to compute the root-to-node transformation. + * + * `cgltf_accessor_unpack_floats` reads in the data from an accessor, applies sparse data (if any), + * and converts them to floating point. Assumes that `cgltf_load_buffers` has already been called. + * By passing null for the output pointer, users can find out how many floats are required in the + * output buffer. + * + * `cgltf_accessor_unpack_indices` reads in the index data from an accessor. Assumes that + * `cgltf_load_buffers` has already been called. By passing null for the output pointer, users can + * find out how many indices are required in the output buffer. Returns 0 if the accessor is + * sparse or if the output component size is less than the accessor's component size. + * + * `cgltf_num_components` is a tiny utility that tells you the dimensionality of + * a certain accessor type. This can be used before `cgltf_accessor_unpack_floats` to help allocate + * the necessary amount of memory. `cgltf_component_size` and `cgltf_calc_size` exist for + * similar purposes. + * + * `cgltf_accessor_read_float` reads a certain element from a non-sparse accessor and converts it to + * floating point, assuming that `cgltf_load_buffers` has already been called. The passed-in element + * size is the number of floats in the output buffer, which should be in the range [1, 16]. Returns + * false if the passed-in element_size is too small, or if the accessor is sparse. + * + * `cgltf_accessor_read_uint` is similar to its floating-point counterpart, but limited to reading + * vector types and does not support matrix types. The passed-in element size is the number of uints + * in the output buffer, which should be in the range [1, 4]. Returns false if the passed-in + * element_size is too small, or if the accessor is sparse. + * + * `cgltf_accessor_read_index` is similar to its floating-point counterpart, but it returns size_t + * and only works with single-component data types. + * + * `cgltf_copy_extras_json` allows users to retrieve the "extras" data that can be attached to many + * glTF objects (which can be arbitrary JSON data). This is a legacy function, consider using + * cgltf_extras::data directly instead. You can parse this data using your own JSON parser + * or, if you've included the cgltf implementation using the integrated JSMN JSON parser. + */ +#ifndef CGLTF_H_INCLUDED__ +#define CGLTF_H_INCLUDED__ + +#include +#include /* For uint8_t, uint32_t */ + +#ifdef __cplusplus +extern "C" { +#endif + +typedef size_t cgltf_size;

To use it, do something like the following in one .c file. + + ```c + #define DR_FLAC_IMPLEMENTATION + #include "dr_flac.h" + ``` + +You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following: + + ```c + drflac* pFlac = drflac_open_file("MySong.flac", NULL); + if (pFlac == NULL) { + // Failed to open FLAC file + } + + drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32)); + drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples); + ``` + +The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of channels and the bits per sample, +should be directly accessible - just make sure you don't change their values. Samples are always output as interleaved signed 32-bit PCM. In the example above +a native FLAC stream was opened, however dr_flac has seamless support for Ogg encapsulated FLAC streams as well. + +You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and the decoder will give you as many +samples as it can, up to the amount requested. Later on when you need the next batch of samples, just call it again. Example: + + ```c + while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) { + do_something(); + } + ``` + +You can seek to a specific PCM frame with `drflac_seek_to_pcm_frame()`. + +If you just want to quickly decode an entire FLAC file in one go you can do something like this: + + ```c + unsigned int channels; + unsigned int sampleRate; + drflac_uint64 totalPCMFrameCount; + drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount, NULL); + if (pSampleData == NULL) { + // Failed to open and decode FLAC file. + } + + ... + + drflac_free(pSampleData, NULL); + ``` + +You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs respectively, but note that these +should be considered lossy. + + +If you need access to metadata (album art, etc.), use `drflac_open_with_metadata()`, `drflac_open_file_with_metdata()` or `drflac_open_memory_with_metadata()`. +The rationale for keeping these APIs separate is that they're slightly slower than the normal versions and also just a little bit harder to use. dr_flac +reports metadata to the application through the use of a callback, and every metadata block is reported before `drflac_open_with_metdata()` returns. + +The main opening APIs (`drflac_open()`, etc.) will fail if the header is not present. The presents a problem in certain scenarios such as broadcast style +streams or internet radio where the header may not be present because the user has started playback mid-stream. To handle this, use the relaxed APIs: + + `drflac_open_relaxed()` + `drflac_open_with_metadata_relaxed()` + +It is not recommended to use these APIs for file based streams because a missing header would usually indicate a corrupt or perverse file. In addition, these +APIs can take a long time to initialize because they may need to spend a lot of time finding the first frame. + + + +Build Options +============= +#define these options before including this file. + +#define DR_FLAC_NO_STDIO + Disable `drflac_open_file()` and family. + +#define DR_FLAC_NO_OGG + Disables support for Ogg/FLAC streams. + +#define DR_FLAC_BUFFER_SIZE + Defines the size of the internal buffer to store data from onRead(). This buffer is used to reduce the number of calls back to the client for more data. + Larger values means more memory, but better performance. My tests show diminishing returns after about 4KB (which is the default). Consider reducing this if + you have a very efficient implementation of onRead(), or increase it if it's very inefficient. Must be a multiple of 8. + +#define DR_FLAC_NO_CRC + Disables CRC checks. This will offer a performance boost when CRC is unnecessary. This will disable binary search seeking. When seeking, the seek table will + be used if available. Otherwise the seek will be performed using brute force. + +#define DR_FLAC_NO_SIMD + Disables SIMD optimizations (SSE on x86/x64 architectures, NEON on ARM architectures). Use this if you are having compatibility issues with your compiler. + +#define DR_FLAC_NO_WCHAR + Disables all functions ending with `_w`. Use this if your compiler does not provide wchar.h. Not required if DR_FLAC_NO_STDIO is also defined. + + + +Notes +===== +- dr_flac does not support changing the sample rate nor channel count mid stream. +- dr_flac is not thread-safe, but its APIs can be called from any thread so long as you do your own synchronization. +- When using Ogg encapsulation, a corrupted metadata block will result in `drflac_open_with_metadata()` and `drflac_open()` returning inconsistent samples due + to differences in corrupted stream recorvery logic between the two APIs. +*/ + +#ifndef dr_flac_h +#define dr_flac_h + +#ifdef __cplusplus +extern "C" { +#endif + +#define DRFLAC_STRINGIFY(x) #x +#define DRFLAC_XSTRINGIFY(x) DRFLAC_STRINGIFY(x) + +#define DRFLAC_VERSION_MAJOR 0 +#define DRFLAC_VERSION_MINOR 13 +#define DRFLAC_VERSION_REVISION 0 +#define DRFLAC_VERSION_STRING DRFLAC_XSTRINGIFY(DRFLAC_VERSION_MAJOR) "."

See the bottom of this file for differences between minimp3 and dr_mp3. +*/ + +/* +Introduction +============= +dr_mp3 is a single file library. To use it, do something like the following in one .c file. + + ```c + #define DR_MP3_IMPLEMENTATION + #include "dr_mp3.h" + ``` + +You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following: + + ```c + drmp3 mp3; + if (!drmp3_init_file(&mp3, "MySong.mp3", NULL)) { + // Failed to open file + } + + ... + + drmp3_uint64 framesRead = drmp3_read_pcm_frames_f32(pMP3, framesToRead, pFrames); + ``` + +The drmp3 object is transparent so you can get access to the channel count and sample rate like so: + + ``` + drmp3_uint32 channels = mp3.channels; + drmp3_uint32 sampleRate = mp3.sampleRate; + ``` + +The example above initializes a decoder from a file, but you can also initialize it from a block of memory and read and seek callbacks with +`drmp3_init_memory()` and `drmp3_init()` respectively. + +You do not need to do any annoying memory management when reading PCM frames - this is all managed internally. You can request any number of PCM frames in each +call to `drmp3_read_pcm_frames_f32()` and it will return as many PCM frames as it can, up to the requested amount. + +You can also decode an entire file in one go with `drmp3_open_and_read_pcm_frames_f32()`, `drmp3_open_memory_and_read_pcm_frames_f32()` and +`drmp3_open_file_and_read_pcm_frames_f32()`. + + +Build Options +============= +#define these options before including this file. + +#define DR_MP3_NO_STDIO + Disable drmp3_init_file(), etc. + +#define DR_MP3_NO_SIMD + Disable SIMD optimizations. +*/ + +#ifndef dr_mp3_h +#define dr_mp3_h + +#ifdef __cplusplus +extern "C" { +#endif + +#define DRMP3_STRINGIFY(x) #x +#define DRMP3_XSTRINGIFY(x) DRMP3_STRINGIFY(x) + +#define DRMP3_VERSION_MAJOR 0 +#define DRMP3_VERSION_MINOR 7 +#define DRMP3_VERSION_REVISION 0 +#define DRMP3_VERSION_STRING DRMP3_XSTRINGIFY(DRMP3_VERSION_MAJOR) "."

All of the + code relating to the actual decoding remains mostly unmodified, apart from some namespacing changes. +- dr_mp3 adds a pulling style API which allows you to deliver raw data via callbacks. So, rather than pushing data + to the decoder, the decoder _pulls_ data from your callbacks. +- In addition to callbacks, a decoder can be initialized from a block of memory and a file. +- The dr_mp3 pull API reads PCM frames rather than whole MP3 frames. +- dr_mp3 adds convenience APIs for opening and decoding entire files in one go. +- dr_mp3 is fully namespaced, including the implementation section, which is more suitable when compiling projects + as a single translation unit (aka unity builds). At the time of writing this, a unity build is not possible when + using minimp3 in conjunction with stb_vorbis. dr_mp3 addresses this. +*/ + +/* +REVISION HISTORY +================ +v0.7.0 - TBD + - The old `DRMP3_IMPLEMENTATION` has been removed. Use `DR_MP3_IMPLEMENTATION` instead. The reason for this change is that in the future everything will eventually be using the underscored naming convention in the future, so `drmp3` will become `dr_mp3`. + - API CHANGE: Seek origins have been renamed to match the naming convention used by dr_wav and my other libraries. + - drmp3_seek_origin_start -> DRMP3_SEEK_SET + - drmp3_seek_origin_current -> DRMP3_SEEK_CUR + - DRMP3_SEEK_END (new) + - API CHANGE: Add DRMP3_SEEK_END as a seek origin for the seek callback. This is required for detection of ID3v1 and APE tags. + - API CHANGE: Add onTell callback to `drmp3_init()`. This is needed in order to track the location of ID3v1 and APE tags. + - API CHANGE: Add onMeta callback to `drmp3_init()`. This is used for reporting tag data back to the caller. Currently this only reports the raw tag data which means applications need to parse the data themselves. + - API CHANGE: Rename `drmp3dec_frame_info.hz` to `drmp3dec_frame_info.sample_rate`. + - Add detection of ID3v2, ID3v1, APE and Xing/VBRI tags. This should fix errors with some files where the decoder was reading tags as audio data. + - Delay and padding samples from LAME tags are now handled. + - Fix compilation for AIX OS. + +v0.6.40 - 2024-12-17 + - Improve detection of ARM64EC + +v0.6.39 - 2024-02-27 + - Fix a Wdouble-promotion warning. + +v0.6.38 - 2023-11-02 + - Fix build for ARMv6-M. + +v0.6.37 - 2023-07-07 + - Silence a static analysis warning. + +v0.6.36 - 2023-06-17 + - Fix an incorrect date in revision history.

To use it, do something like the following in one .c file. + + ```c + #define DR_WAV_IMPLEMENTATION + #include "dr_wav.h" + ``` + +You can then #include this file in other parts of the program as you would with any other header file. Do something like the following to read audio data: + + ```c + drwav wav; + if (!drwav_init_file(&wav, "my_song.wav", NULL)) { + // Error opening WAV file. + } + + drwav_int32* pDecodedInterleavedPCMFrames = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32)); + size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames); + + ... + + drwav_uninit(&wav); + ``` + +If you just want to quickly open and read the audio data in a single operation you can do something like this: + + ```c + unsigned int channels; + unsigned int sampleRate; + drwav_uint64 totalPCMFrameCount; + float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount, NULL); + if (pSampleData == NULL) { + // Error opening and reading WAV file. + } + + ... + + drwav_free(pSampleData, NULL); + ``` + +The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in this case), but you can still output the +audio data in its internal format (see notes below for supported formats): + + ```c + size_t framesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames); + ``` + +You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for a particular data format: + + ```c + size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer); + ``` + +dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at `drwav_init_write()`, +`drwav_init_file_write()`, etc. Use `drwav_write_pcm_frames()` to write samples, or `drwav_write_raw()` to write raw data in the "data" chunk. + + ```c + drwav_data_format format; + format.container = drwav_container_riff; // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64. + format.format = DR_WAVE_FORMAT_PCM; // <-- Any of the DR_WAVE_FORMAT_* codes. + format.channels = 2; + format.sampleRate = 44100; + format.bitsPerSample = 16; + drwav_init_file_write(&wav, "data/recording.wav", &format, NULL); + + ... + + drwav_uint64 framesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples); + ``` + +Note that writing to AIFF or RIFX is not supported. + +dr_wav has support for decoding from a number of different encapsulation formats. See below for details. + + +Build Options +============= +#define these options before including this file. + +#define DR_WAV_NO_CONVERSION_API + Disables conversion APIs such as `drwav_read_pcm_frames_f32()` and `drwav_s16_to_f32()`. + +#define DR_WAV_NO_STDIO + Disables APIs that initialize a decoder from a file such as `drwav_init_file()`, `drwav_init_file_write()`, etc. + +#define DR_WAV_NO_WCHAR + Disables all functions ending with `_w`.

This is a special singleton object. It + is used for internal Wayland protocol features. + + + + + The sync request asks the server to emit the 'done' event + on the returned wl_callback object. Since requests are + handled in-order and events are delivered in-order, this can + be used as a barrier to ensure all previous requests and the + resulting events have been handled. + + The object returned by this request will be destroyed by the + compositor after the callback is fired and as such the client must not + attempt to use it after that point. + + The callback_data passed in the callback is the event serial. + + + + + + + This request creates a registry object that allows the client + to list and bind the global objects available from the + compositor. + + It should be noted that the server side resources consumed in + response to a get_registry request can only be released when the + client disconnects, not when the client side proxy is destroyed. + Therefore, clients should invoke get_registry as infrequently as + possible to avoid wasting memory. + + + + + + + The error event is sent out when a fatal (non-recoverable) + error has occurred. The object_id argument is the object + where the error occurred, most often in response to a request + to that object. The code identifies the error and is defined + by the object interface. As such, each interface defines its + own set of error codes. The message is a brief description + of the error, for (debugging) convenience. + + + + + + + + + These errors are global and can be emitted in response to any + server request. + + + + + + + + + + This event is used internally by the object ID management + logic. When a client deletes an object that it had created, + the server will send this event to acknowledge that it has + seen the delete request. When the client receives this event, + it will know that it can safely reuse the object ID. + + + + + + + + The singleton global registry object. The server has a number of + global objects that are available to all clients. These objects + typically represent an actual object in the server (for example, + an input device) or they are singleton objects that provide + extension functionality. + + When a client creates a registry object, the registry object + will emit a global event for each global currently in the + registry. Globals come and go as a result of device or + monitor hotplugs, reconfiguration or other events, and the + registry will send out global and global_remove events to + keep the client up to date with the changes. To mark the end + of the initial burst of events, the client can use the + wl_display.sync request immediately after calling + wl_display.get_registry. + + A client can bind to a global object by using the bind + request. This creates a client-side handle that lets the object + emit events to the client and lets the client invoke requests on + the object. + + + + + Binds a new, client-created object to the server using the + specified name as the identifier. + + + + + + + + Notify the client of global objects. + + The event notifies the client that a global object with + the given name is now available, and it implements the + given version of the given interface. + + + + + + + + + Notify the client of removed global objects. + + This event notifies the client that the global identified + by name is no longer available. If the client bound to + the global using the bind request, the client should now + destroy that object. + + The object remains valid and requests to the object will be + ignored until the client destroys it, to avoid races between + the global going away and a client sending a request to it. + + + + + + + + Clients can handle the 'done' event to get notified when + the related request is done. + + Note, because wl_callback objects are created from multiple independent + factory interfaces, the wl_callback interface is frozen at version 1. + + + + + Notify the client when the related request is done. + + + + + + + + A compositor. This object is a singleton global. The + compositor is in charge of combining the contents of multiple + surfaces into one displayable output. + + + + + Ask the compositor to create a new surface. + + + + + + + Ask the compositor to create a new region. + + + + + + + + The wl_shm_pool object encapsulates a piece of memory shared + between the compositor and client. Through the wl_shm_pool + object, the client can allocate shared memory wl_buffer objects. + All objects created through the same pool share the same + underlying mapped memory. Reusing the mapped memory avoids the + setup/teardown overhead and is useful when interactively resizing + a surface or for many small buffers. + + + + + Create a wl_buffer object from the pool. + + The buffer is created offset bytes into the pool and has + width and height as specified. The stride argument specifies + the number of bytes from the beginning of one row to the beginning + of the next. The format is the pixel format of the buffer and + must be one of those advertised through the wl_shm.format event. + + A buffer will keep a reference to the pool it was created from + so it is valid to destroy the pool immediately after creating + a buffer from it. + + + + + + + + + + + + Destroy the shared memory pool. + + The mmapped memory will be released when all + buffers that have been created from this pool + are gone. + + + + + + This request will cause the server to remap the backing memory + for the pool from the file descriptor passed when the pool was + created, but using the new size. This request can only be + used to make the pool bigger. + + This request only changes the amount of bytes that are mmapped + by the server and does not touch the file corresponding to the + file descriptor passed at creation time. It is the client's + responsibility to ensure that the file is at least as big as + the new pool size. + + + + + + + + A singleton global object that provides support for shared + memory. + + Clients can create wl_shm_pool objects using the create_pool + request. + + On binding the wl_shm object one or more format events + are emitted to inform clients about the valid pixel formats + that can be used for buffers. + + + + + These errors can be emitted in response to wl_shm requests. + + + + + + + + + This describes the memory layout of an individual pixel. + + All renderers should support argb8888 and xrgb8888 but any other + formats are optional and may not be supported by the particular + renderer in use. + + The drm format codes match the macros defined in drm_fourcc.h, except + argb8888 and xrgb8888. The formats actually supported by the compositor + will be reported by the format event. + + For all wl_shm formats and unless specified in another protocol + extension, pre-multiplied alpha is used for pixel values. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Create a new wl_shm_pool object. + + The pool can be used to create shared memory based buffer + objects. The server will mmap size bytes of the passed file + descriptor, to use as backing memory for the pool. + + + + + + + + + Informs the client about a valid pixel format that + can be used for buffers. Known formats include + argb8888 and xrgb8888. + + + + + + + + A buffer provides the content for a wl_surface. Buffers are + created through factory interfaces such as wl_shm, wp_linux_buffer_params + (from the linux-dmabuf protocol extension) or similar. It has a width and + a height and can be attached to a wl_surface, but the mechanism by which a + client provides and updates the contents is defined by the buffer factory + interface. + + If the buffer uses a format that has an alpha channel, the alpha channel + is assumed to be premultiplied in the color channels unless otherwise + specified. + + Note, because wl_buffer objects are created from multiple independent + factory interfaces, the wl_buffer interface is frozen at version 1. + + + + + Destroy a buffer. If and how you need to release the backing + storage is defined by the buffer factory interface. + + For possible side-effects to a surface, see wl_surface.attach. + + + + + + Sent when this wl_buffer is no longer used by the compositor. + The client is now free to reuse or destroy this buffer and its + backing storage. + + If a client receives a release event before the frame callback + requested in the same wl_surface.commit that attaches this + wl_buffer to a surface, then the client is immediately free to + reuse the buffer and its backing storage, and does not need a + second buffer for the next surface content update. Typically + this is possible, when the compositor maintains a copy of the + wl_surface contents, e.g. as a GL texture. This is an important + optimization for GL(ES) compositors with wl_shm clients. + + + + + + + A wl_data_offer represents a piece of data offered for transfer + by another client (the source client). It is used by the + copy-and-paste and drag-and-drop mechanisms. The offer + describes the different mime types that the data can be + converted to and provides the mechanism for transferring the + data directly from the source client. + + + + + + + + + + + + Indicate that the client can accept the given mime type, or + NULL for not accepted. + + For objects of version 2 or older, this request is used by the + client to give feedback whether the client can receive the given + mime type, or NULL if none is accepted; the feedback does not + determine whether the drag-and-drop operation succeeds or not. + + For objects of version 3 or newer, this request determines the + final result of the drag-and-drop operation. If the end result + is that no mime types were accepted, the drag-and-drop operation + will be cancelled and the corresponding drag source will receive + wl_data_source.cancelled. Clients may still use this event in + conjunction with wl_data_source.action for feedback. + + + + + + + + To transfer the offered data, the client issues this request + and indicates the mime type it wants to receive. The transfer + happens through the passed file descriptor (typically created + with the pipe system call). The source client writes the data + in the mime type representation requested and then closes the + file descriptor. + + The receiving client reads from the read end of the pipe until + EOF and then closes its end, at which point the transfer is + complete. + + This request may happen multiple times for different mime types, + both before and after wl_data_device.drop. Drag-and-drop destination + clients may preemptively fetch data or examine it more closely to + determine acceptance. + + + + + + + + Destroy the data offer. + + + + + + Sent immediately after creating the wl_data_offer object. One + event per offered mime type. + + + + + + + + + Notifies the compositor that the drag destination successfully + finished the drag-and-drop operation. + + Upon receiving this request, the compositor will emit + wl_data_source.dnd_finished on the drag source client. + + It is a client error to perform other requests than + wl_data_offer.destroy after this one. It is also an error to perform + this request after a NULL mime type has been set in + wl_data_offer.accept or no action was received through + wl_data_offer.action. + + If wl_data_offer.finish request is received for a non drag and drop + operation, the invalid_finish protocol error is raised. + + + + + + Sets the actions that the destination side client supports for + this operation. This request may trigger the emission of + wl_data_source.action and wl_data_offer.action events if the compositor + needs to change the selected action. + + This request can be called multiple times throughout the + drag-and-drop operation, typically in response to wl_data_device.enter + or wl_data_device.motion events. + + This request determines the final result of the drag-and-drop + operation. If the end result is that no action is accepted, + the drag source will receive wl_data_source.cancelled. + + The dnd_actions argument must contain only values expressed in the + wl_data_device_manager.dnd_actions enum, and the preferred_action + argument must only contain one of those values set, otherwise it + will result in a protocol error. + + While managing an "ask" action, the destination drag-and-drop client + may perform further wl_data_offer.receive requests, and is expected + to perform one last wl_data_offer.set_actions request with a preferred + action other than "ask" (and optionally wl_data_offer.accept) before + requesting wl_data_offer.finish, in order to convey the action selected + by the user. If the preferred action is not in the + wl_data_offer.source_actions mask, an error will be raised. + + If the "ask" action is dismissed (e.g. user cancellation), the client + is expected to perform wl_data_offer.destroy right away. + + This request can only be made on drag-and-drop offers, a protocol error + will be raised otherwise. + + + + + + + + This event indicates the actions offered by the data source. It + will be sent immediately after creating the wl_data_offer object, + or anytime the source side changes its offered actions through + wl_data_source.set_actions. + + + + + + + This event indicates the action selected by the compositor after + matching the source/destination side actions. Only one action (or + none) will be offered here. + + This event can be emitted multiple times during the drag-and-drop + operation in response to destination side action changes through + wl_data_offer.set_actions. + + This event will no longer be emitted after wl_data_device.drop + happened on the drag-and-drop destination, the client must + honor the last action received, or the last preferred one set + through wl_data_offer.set_actions when handling an "ask" action. + + Compositors may also change the selected action on the fly, mainly + in response to keyboard modifier changes during the drag-and-drop + operation. + + The most recent action received is always the valid one. Prior to + receiving wl_data_device.drop, the chosen action may change (e.g. + due to keyboard modifiers being pressed). At the time of receiving + wl_data_device.drop the drag-and-drop destination must honor the + last action received. + + Action changes may still happen after wl_data_device.drop, + especially on "ask" actions, where the drag-and-drop destination + may choose another action afterwards. Action changes happening + at this stage are always the result of inter-client negotiation, the + compositor shall no longer be able to induce a different action. + + Upon "ask" actions, it is expected that the drag-and-drop destination + may potentially choose a different action and/or mime type, + based on wl_data_offer.source_actions and finally chosen by the + user (e.g. popping up a menu with the available options). The + final wl_data_offer.set_actions and wl_data_offer.accept requests + must happen before the call to wl_data_offer.finish. + + + + + + + + The wl_data_source object is the source side of a wl_data_offer. + It is created by the source client in a data transfer and + provides a way to describe the offered data and a way to respond + to requests to transfer the data. + + + + + + + + + + This request adds a mime type to the set of mime types + advertised to targets. Can be called several times to offer + multiple types. + + + + + + + Destroy the data source. + + + + + + Sent when a target accepts pointer_focus or motion events. If + a target does not accept any of the offered types, type is NULL. + + Used for feedback during drag-and-drop. + + + + + + + Request for data from the client. Send the data as the + specified mime type over the passed file descriptor, then + close it. + + + + + + + + This data source is no longer valid. There are several reasons why + this could happen: + + - The data source has been replaced by another data source. + - The drag-and-drop operation was performed, but the drop destination + did not accept any of the mime types offered through + wl_data_source.target. + - The drag-and-drop operation was performed, but the drop destination + did not select any of the actions present in the mask offered through + wl_data_source.action. + - The drag-and-drop operation was performed but didn't happen over a + surface. + - The compositor cancelled the drag-and-drop operation (e.g. compositor + dependent timeouts to avoid stale drag-and-drop transfers). + + The client should clean up and destroy this data source. + + For objects of version 2 or older, wl_data_source.cancelled will + only be emitted if the data source was replaced by another data + source. + + + + + + + + Sets the actions that the source side client supports for this + operation. This request may trigger wl_data_source.action and + wl_data_offer.action events if the compositor needs to change the + selected action. + + The dnd_actions argument must contain only values expressed in the + wl_data_device_manager.dnd_actions enum, otherwise it will result + in a protocol error. + + This request must be made once only, and can only be made on sources + used in drag-and-drop, so it must be performed before + wl_data_device.start_drag. Attempting to use the source other than + for drag-and-drop will raise a protocol error. + + + + + + + The user performed the drop action. This event does not indicate + acceptance, wl_data_source.cancelled may still be emitted afterwards + if the drop destination does not accept any mime type. + + However, this event might however not be received if the compositor + cancelled the drag-and-drop operation before this event could happen. + + Note that the data_source may still be used in the future and should + not be destroyed here. + + + + + + The drop destination finished interoperating with this data + source, so the client is now free to destroy this data source and + free all associated data. + + If the action used to perform the operation was "move", the + source can now delete the transferred data. + + + + + + This event indicates the action selected by the compositor after + matching the source/destination side actions. Only one action (or + none) will be offered here. + + This event can be emitted multiple times during the drag-and-drop + operation, mainly in response to destination side changes through + wl_data_offer.set_actions, and as the data device enters/leaves + surfaces. + + It is only possible to receive this event after + wl_data_source.dnd_drop_performed if the drag-and-drop operation + ended in an "ask" action, in which case the final wl_data_source.action + event will happen immediately before wl_data_source.dnd_finished. + + Compositors may also change the selected action on the fly, mainly + in response to keyboard modifier changes during the drag-and-drop + operation. + + The most recent action received is always the valid one. The chosen + action may change alongside negotiation (e.g. an "ask" action can turn + into a "move" operation), so the effects of the final action must + always be applied in wl_data_offer.dnd_finished. + + Clients can trigger cursor surface changes from this point, so + they reflect the current action. + + + + + + + + There is one wl_data_device per seat which can be obtained + from the global wl_data_device_manager singleton. + + A wl_data_device provides access to inter-client data transfer + mechanisms such as copy-and-paste and drag-and-drop. + + + + + + + + + This request asks the compositor to start a drag-and-drop + operation on behalf of the client. + + The source argument is the data source that provides the data + for the eventual data transfer. If source is NULL, enter, leave + and motion events are sent only to the client that initiated the + drag and the client is expected to handle the data passing + internally. If source is destroyed, the drag-and-drop session will be + cancelled. + + The origin surface is the surface where the drag originates and + the client must have an active implicit grab that matches the + serial. + + The icon surface is an optional (can be NULL) surface that + provides an icon to be moved around with the cursor. Initially, + the top-left corner of the icon surface is placed at the cursor + hotspot, but subsequent wl_surface.attach request can move the + relative position. Attach requests must be confirmed with + wl_surface.commit as usual. The icon surface is given the role of + a drag-and-drop icon. If the icon surface already has another role, + it raises a protocol error. + + The input region is ignored for wl_surfaces with the role of a + drag-and-drop icon. + + + + + + + + + + This request asks the compositor to set the selection + to the data from the source on behalf of the client. + + To unset the selection, set the source to NULL. + + + + + + + + The data_offer event introduces a new wl_data_offer object, + which will subsequently be used in either the + data_device.enter event (for drag-and-drop) or the + data_device.selection event (for selections). Immediately + following the data_device.data_offer event, the new data_offer + object will send out data_offer.offer events to describe the + mime types it offers. + + + + + + + This event is sent when an active drag-and-drop pointer enters + a surface owned by the client. The position of the pointer at + enter time is provided by the x and y arguments, in surface-local + coordinates. + + + + + + + + + + + This event is sent when the drag-and-drop pointer leaves the + surface and the session ends. The client must destroy the + wl_data_offer introduced at enter time at this point. + + + + + + This event is sent when the drag-and-drop pointer moves within + the currently focused surface. The new position of the pointer + is provided by the x and y arguments, in surface-local + coordinates. + + + + + + + + + The event is sent when a drag-and-drop operation is ended + because the implicit grab is removed. + + The drag-and-drop destination is expected to honor the last action + received through wl_data_offer.action, if the resulting action is + "copy" or "move", the destination can still perform + wl_data_offer.receive requests, and is expected to end all + transfers with a wl_data_offer.finish request. + + If the resulting action is "ask", the action will not be considered + final. The drag-and-drop destination is expected to perform one last + wl_data_offer.set_actions request, or wl_data_offer.destroy in order + to cancel the operation. + + + + + + The selection event is sent out to notify the client of a new + wl_data_offer for the selection for this device. The + data_device.data_offer and the data_offer.offer events are + sent out immediately before this event to introduce the data + offer object. The selection event is sent to a client + immediately before receiving keyboard focus and when a new + selection is set while the client has keyboard focus. The + data_offer is valid until a new data_offer or NULL is received + or until the client loses keyboard focus. Switching surface with + keyboard focus within the same client doesn't mean a new selection + will be sent. The client must destroy the previous selection + data_offer, if any, upon receiving this event. + + + + + + + + + This request destroys the data device. + + + + + + + The wl_data_device_manager is a singleton global object that + provides access to inter-client data transfer mechanisms such as + copy-and-paste and drag-and-drop. These mechanisms are tied to + a wl_seat and this interface lets a client get a wl_data_device + corresponding to a wl_seat. + + Depending on the version bound, the objects created from the bound + wl_data_device_manager object will have different requirements for + functioning properly. See wl_data_source.set_actions, + wl_data_offer.accept and wl_data_offer.finish for details. + + + + + Create a new data source. + + + + + + + Create a new data device for a given seat. + + + + + + + + + + This is a bitmask of the available/preferred actions in a + drag-and-drop operation. + + In the compositor, the selected action is a result of matching the + actions offered by the source and destination sides. "action" events + with a "none" action will be sent to both source and destination if + there is no match. All further checks will effectively happen on + (source actions ∩ destination actions). + + In addition, compositors may also pick different actions in + reaction to key modifiers being pressed. One common design that + is used in major toolkits (and the behavior recommended for + compositors) is: + + - If no modifiers are pressed, the first match (in bit order) + will be used. + - Pressing Shift selects "move", if enabled in the mask. + - Pressing Control selects "copy", if enabled in the mask. + + Behavior beyond that is considered implementation-dependent. + Compositors may for example bind other modifiers (like Alt/Meta) + or drags initiated with other buttons than BTN_LEFT to specific + actions (e.g. "ask"). + + + + + + + + + + + This interface is implemented by servers that provide + desktop-style user interfaces. + + It allows clients to associate a wl_shell_surface with + a basic surface. + + Note! This protocol is deprecated and not intended for production use. + For desktop-style user interfaces, use xdg_shell. Compositors and clients + should not implement this interface. + + + + + + + + + Create a shell surface for an existing surface. This gives + the wl_surface the role of a shell surface. If the wl_surface + already has another role, it raises a protocol error. + + Only one shell surface can be associated with a given surface. + + + + + + + + + An interface that may be implemented by a wl_surface, for + implementations that provide a desktop-style user interface. + + It provides requests to treat surfaces like toplevel, fullscreen + or popup windows, move, resize or maximize them, associate + metadata like title and class, etc. + + On the server side the object is automatically destroyed when + the related wl_surface is destroyed. On the client side, + wl_shell_surface_destroy() must be called before destroying + the wl_surface object. + + + + + A client must respond to a ping event with a pong request or + the client may be deemed unresponsive. + + + + + + + Start a pointer-driven move of the surface. + + This request must be used in response to a button press event. + The server may ignore move requests depending on the state of + the surface (e.g. fullscreen or maximized). + + + + + + + + These values are used to indicate which edge of a surface + is being dragged in a resize operation. The server may + use this information to adapt its behavior, e.g. choose + an appropriate cursor image. + + + + + + + + + + + + + + + Start a pointer-driven resizing of the surface. + + This request must be used in response to a button press event. + The server may ignore resize requests depending on the state of + the surface (e.g. fullscreen or maximized). + + + + + + + + + Map the surface as a toplevel surface. + + A toplevel surface is not fullscreen, maximized or transient. + + + + + + These flags specify details of the expected behaviour + of transient surfaces. Used in the set_transient request. + + + + + + + Map the surface relative to an existing surface. + + The x and y arguments specify the location of the upper left + corner of the surface relative to the upper left corner of the + parent surface, in surface-local coordinates. + + The flags argument controls details of the transient behaviour. + + + + + + + + + + Hints to indicate to the compositor how to deal with a conflict + between the dimensions of the surface and the dimensions of the + output. The compositor is free to ignore this parameter. + + + + + + + + + + Map the surface as a fullscreen surface. + + If an output parameter is given then the surface will be made + fullscreen on that output. If the client does not specify the + output then the compositor will apply its policy - usually + choosing the output on which the surface has the biggest surface + area. + + The client may specify a method to resolve a size conflict + between the output size and the surface size - this is provided + through the method parameter. + + The framerate parameter is used only when the method is set + to "driver", to indicate the preferred framerate. A value of 0 + indicates that the client does not care about framerate. The + framerate is specified in mHz, that is framerate of 60000 is 60Hz. + + A method of "scale" or "driver" implies a scaling operation of + the surface, either via a direct scaling operation or a change of + the output mode. This will override any kind of output scaling, so + that mapping a surface with a buffer size equal to the mode can + fill the screen independent of buffer_scale. + + A method of "fill" means we don't scale up the buffer, however + any output scale is applied. This means that you may run into + an edge case where the application maps a buffer with the same + size of the output mode but buffer_scale 1 (thus making a + surface larger than the output). In this case it is allowed to + downscale the results to fit the screen. + + The compositor must reply to this request with a configure event + with the dimensions for the output on which the surface will + be made fullscreen. + + + + + + + + + Map the surface as a popup. + + A popup surface is a transient surface with an added pointer + grab. + + An existing implicit grab will be changed to owner-events mode, + and the popup grab will continue after the implicit grab ends + (i.e. releasing the mouse button does not cause the popup to + be unmapped). + + The popup grab continues until the window is destroyed or a + mouse button is pressed in any other client's window. A click + in any of the client's surfaces is reported as normal, however, + clicks in other clients' surfaces will be discarded and trigger + the callback. + + The x and y arguments specify the location of the upper left + corner of the surface relative to the upper left corner of the + parent surface, in surface-local coordinates. + + + + + + + + + + + + Map the surface as a maximized surface. + + If an output parameter is given then the surface will be + maximized on that output. If the client does not specify the + output then the compositor will apply its policy - usually + choosing the output on which the surface has the biggest surface + area. + + The compositor will reply with a configure event telling + the expected new surface size. The operation is completed + on the next buffer attach to this surface. + + A maximized surface typically fills the entire output it is + bound to, except for desktop elements such as panels. This is + the main difference between a maximized shell surface and a + fullscreen shell surface. + + The details depend on the compositor implementation. + + + + + + + Set a short title for the surface. + + This string may be used to identify the surface in a task bar, + window list, or other user interface elements provided by the + compositor. + + The string must be encoded in UTF-8. + + + + + + + Set a class for the surface. + + The surface class identifies the general class of applications + to which the surface belongs. A common convention is to use the + file name (or the full path if it is a non-standard location) of + the application's .desktop file as the class. + + + + + + + Ping a client to check if it is receiving events and sending + requests. A client is expected to reply with a pong request. + + + + + + + The configure event asks the client to resize its surface. + + The size is a hint, in the sense that the client is free to + ignore it if it doesn't resize, pick a smaller size (to + satisfy aspect ratio or resize in steps of NxM pixels). + + The edges parameter provides a hint about how the surface + was resized. The client may use this information to decide + how to adjust its content to the new size (e.g. a scrolling + area might adjust its content position to leave the viewable + content unmoved). + + The client is free to dismiss all but the last configure + event it received. + + The width and height arguments specify the size of the window + in surface-local coordinates. + + + + + + + + + The popup_done event is sent out when a popup grab is broken, + that is, when the user clicks a surface that doesn't belong + to the client owning the popup surface. + + + + + + + A surface is a rectangular area that may be displayed on zero + or more outputs, and shown any number of times at the compositor's + discretion. They can present wl_buffers, receive user input, and + define a local coordinate system. + + The size of a surface (and relative positions on it) is described + in surface-local coordinates, which may differ from the buffer + coordinates of the pixel content, in case a buffer_transform + or a buffer_scale is used. + + A surface without a "role" is fairly useless: a compositor does + not know where, when or how to present it. The role is the + purpose of a wl_surface. Examples of roles are a cursor for a + pointer (as set by wl_pointer.set_cursor), a drag icon + (wl_data_device.start_drag), a sub-surface + (wl_subcompositor.get_subsurface), and a window as defined by a + shell protocol (e.g. wl_shell.get_shell_surface). + + A surface can have only one role at a time. Initially a + wl_surface does not have a role. Once a wl_surface is given a + role, it is set permanently for the whole lifetime of the + wl_surface object. Giving the current role again is allowed, + unless explicitly forbidden by the relevant interface + specification. + + Surface roles are given by requests in other interfaces such as + wl_pointer.set_cursor. The request should explicitly mention + that this request gives a role to a wl_surface. Often, this + request also creates a new protocol object that represents the + role and adds additional functionality to wl_surface. When a + client wants to destroy a wl_surface, they must destroy this role + object before the wl_surface, otherwise a defunct_role_object error is + sent. + + Destroying the role object does not remove the role from the + wl_surface, but it may stop the wl_surface from "playing the role". + For instance, if a wl_subsurface object is destroyed, the wl_surface + it was created for will be unmapped and forget its position and + z-order. It is allowed to create a wl_subsurface for the same + wl_surface again, but it is not allowed to use the wl_surface as + a cursor (cursor is a different role than sub-surface, and role + switching is not allowed). + + + + + These errors can be emitted in response to wl_surface requests. + + + + + + + + + + + Deletes the surface and invalidates its object ID. + + + + + + Set a buffer as the content of this surface. + + The new size of the surface is calculated based on the buffer + size transformed by the inverse buffer_transform and the + inverse buffer_scale. This means that at commit time the supplied + buffer size must be an integer multiple of the buffer_scale. If + that's not the case, an invalid_size error is sent. + + The x and y arguments specify the location of the new pending + buffer's upper left corner, relative to the current buffer's upper + left corner, in surface-local coordinates. In other words, the + x and y, combined with the new surface size define in which + directions the surface's size changes. Setting anything other than 0 + as x and y arguments is discouraged, and should instead be replaced + with using the separate wl_surface.offset request. + + When the bound wl_surface version is 5 or higher, passing any + non-zero x or y is a protocol violation, and will result in an + 'invalid_offset' error being raised. The x and y arguments are ignored + and do not change the pending state. To achieve equivalent semantics, + use wl_surface.offset. + + Surface contents are double-buffered state, see wl_surface.commit. + + The initial surface contents are void; there is no content. + wl_surface.attach assigns the given wl_buffer as the pending + wl_buffer. wl_surface.commit makes the pending wl_buffer the new + surface contents, and the size of the surface becomes the size + calculated from the wl_buffer, as described above. After commit, + there is no pending buffer until the next attach. + + Committing a pending wl_buffer allows the compositor to read the + pixels in the wl_buffer. The compositor may access the pixels at + any time after the wl_surface.commit request. When the compositor + will not access the pixels anymore, it will send the + wl_buffer.release event. Only after receiving wl_buffer.release, + the client may reuse the wl_buffer. A wl_buffer that has been + attached and then replaced by another attach instead of committed + will not receive a release event, and is not used by the + compositor. + + If a pending wl_buffer has been committed to more than one wl_surface, + the delivery of wl_buffer.release events becomes undefined. A well + behaved client should not rely on wl_buffer.release events in this + case. Alternatively, a client could create multiple wl_buffer objects + from the same backing storage or use wp_linux_buffer_release. + + Destroying the wl_buffer after wl_buffer.release does not change + the surface contents. Destroying the wl_buffer before wl_buffer.release + is allowed as long as the underlying buffer storage isn't re-used (this + can happen e.g. on client process termination). However, if the client + destroys the wl_buffer before receiving the wl_buffer.release event and + mutates the underlying buffer storage, the surface contents become + undefined immediately. + + If wl_surface.attach is sent with a NULL wl_buffer, the + following wl_surface.commit will remove the surface content. + + + + + + + + + This request is used to describe the regions where the pending + buffer is different from the current surface contents, and where + the surface therefore needs to be repainted. The compositor + ignores the parts of the damage that fall outside of the surface. + + Damage is double-buffered state, see wl_surface.commit. + + The damage rectangle is specified in surface-local coordinates, + where x and y specify the upper left corner of the damage rectangle. + + The initial value for pending damage is empty: no damage. + wl_surface.damage adds pending damage: the new pending damage + is the union of old pending damage and the given rectangle. + + wl_surface.commit assigns pending damage as the current damage, + and clears pending damage. The server will clear the current + damage as it repaints the surface. + + Note! New clients should not use this request. Instead damage can be + posted with wl_surface.damage_buffer which uses buffer coordinates + instead of surface coordinates. + + + + + + + + + + Request a notification when it is a good time to start drawing a new + frame, by creating a frame callback. This is useful for throttling + redrawing operations, and driving animations. + + When a client is animating on a wl_surface, it can use the 'frame' + request to get notified when it is a good time to draw and commit the + next frame of animation. If the client commits an update earlier than + that, it is likely that some updates will not make it to the display, + and the client is wasting resources by drawing too often. + + The frame request will take effect on the next wl_surface.commit. + The notification will only be posted for one frame unless + requested again. For a wl_surface, the notifications are posted in + the order the frame requests were committed. + + The server must send the notifications so that a client + will not send excessive updates, while still allowing + the highest possible update rate for clients that wait for the reply + before drawing again. The server should give some time for the client + to draw and commit after sending the frame callback events to let it + hit the next output refresh. + + A server should avoid signaling the frame callbacks if the + surface is not visible in any way, e.g. the surface is off-screen, + or completely obscured by other opaque surfaces. + + The object returned by this request will be destroyed by the + compositor after the callback is fired and as such the client must not + attempt to use it after that point. + + The callback_data passed in the callback is the current time, in + milliseconds, with an undefined base. + + + + + + + This request sets the region of the surface that contains + opaque content. + + The opaque region is an optimization hint for the compositor + that lets it optimize the redrawing of content behind opaque + regions. Setting an opaque region is not required for correct + behaviour, but marking transparent content as opaque will result + in repaint artifacts. + + The opaque region is specified in surface-local coordinates. + + The compositor ignores the parts of the opaque region that fall + outside of the surface. + + Opaque region is double-buffered state, see wl_surface.commit. + + wl_surface.set_opaque_region changes the pending opaque region. + wl_surface.commit copies the pending region to the current region. + Otherwise, the pending and current regions are never changed. + + The initial value for an opaque region is empty. Setting the pending + opaque region has copy semantics, and the wl_region object can be + destroyed immediately. A NULL wl_region causes the pending opaque + region to be set to empty. + + + + + + + This request sets the region of the surface that can receive + pointer and touch events. + + Input events happening outside of this region will try the next + surface in the server surface stack. The compositor ignores the + parts of the input region that fall outside of the surface. + + The input region is specified in surface-local coordinates. + + Input region is double-buffered state, see wl_surface.commit. + + wl_surface.set_input_region changes the pending input region. + wl_surface.commit copies the pending region to the current region. + Otherwise the pending and current regions are never changed, + except cursor and icon surfaces are special cases, see + wl_pointer.set_cursor and wl_data_device.start_drag. + + The initial value for an input region is infinite. That means the + whole surface will accept input. Setting the pending input region + has copy semantics, and the wl_region object can be destroyed + immediately. A NULL wl_region causes the input region to be set + to infinite. + + + + + + + Surface state (input, opaque, and damage regions, attached buffers, + etc.) is double-buffered. Protocol requests modify the pending state, + as opposed to the current state in use by the compositor. A commit + request atomically applies all pending state, replacing the current + state. After commit, the new pending state is as documented for each + related request. + + On commit, a pending wl_buffer is applied first, and all other state + second. This means that all coordinates in double-buffered state are + relative to the new wl_buffer coming into use, except for + wl_surface.attach itself. If there is no pending wl_buffer, the + coordinates are relative to the current surface contents. + + All requests that need a commit to become effective are documented + to affect double-buffered state. + + Other interfaces may add further double-buffered surface state. + + + + + + This is emitted whenever a surface's creation, movement, or resizing + results in some part of it being within the scanout region of an + output. + + Note that a surface may be overlapping with zero or more outputs. + + + + + + + This is emitted whenever a surface's creation, movement, or resizing + results in it no longer having any part of it within the scanout region + of an output. + + Clients should not use the number of outputs the surface is on for frame + throttling purposes. The surface might be hidden even if no leave event + has been sent, and the compositor might expect new surface content + updates even if no enter event has been sent. The frame event should be + used instead. + + + + + + + + + This request sets an optional transformation on how the compositor + interprets the contents of the buffer attached to the surface. The + accepted values for the transform parameter are the values for + wl_output.transform. + + Buffer transform is double-buffered state, see wl_surface.commit. + + A newly created surface has its buffer transformation set to normal. + + wl_surface.set_buffer_transform changes the pending buffer + transformation. wl_surface.commit copies the pending buffer + transformation to the current one. Otherwise, the pending and current + values are never changed. + + The purpose of this request is to allow clients to render content + according to the output transform, thus permitting the compositor to + use certain optimizations even if the display is rotated. Using + hardware overlays and scanning out a client buffer for fullscreen + surfaces are examples of such optimizations. Those optimizations are + highly dependent on the compositor implementation, so the use of this + request should be considered on a case-by-case basis. + + Note that if the transform value includes 90 or 270 degree rotation, + the width of the buffer will become the surface height and the height + of the buffer will become the surface width. + + If transform is not one of the values from the + wl_output.transform enum the invalid_transform protocol error + is raised. + + + + + + + + + This request sets an optional scaling factor on how the compositor + interprets the contents of the buffer attached to the window. + + Buffer scale is double-buffered state, see wl_surface.commit. + + A newly created surface has its buffer scale set to 1. + + wl_surface.set_buffer_scale changes the pending buffer scale. + wl_surface.commit copies the pending buffer scale to the current one. + Otherwise, the pending and current values are never changed. + + The purpose of this request is to allow clients to supply higher + resolution buffer data for use on high resolution outputs. It is + intended that you pick the same buffer scale as the scale of the + output that the surface is displayed on. This means the compositor + can avoid scaling when rendering the surface on that output. + + Note that if the scale is larger than 1, then you have to attach + a buffer that is larger (by a factor of scale in each dimension) + than the desired surface size. + + If scale is not positive the invalid_scale protocol error is + raised. + + + + + + + + This request is used to describe the regions where the pending + buffer is different from the current surface contents, and where + the surface therefore needs to be repainted. The compositor + ignores the parts of the damage that fall outside of the surface. + + Damage is double-buffered state, see wl_surface.commit. + + The damage rectangle is specified in buffer coordinates, + where x and y specify the upper left corner of the damage rectangle. + + The initial value for pending damage is empty: no damage. + wl_surface.damage_buffer adds pending damage: the new pending + damage is the union of old pending damage and the given rectangle. + + wl_surface.commit assigns pending damage as the current damage, + and clears pending damage. The server will clear the current + damage as it repaints the surface. + + This request differs from wl_surface.damage in only one way - it + takes damage in buffer coordinates instead of surface-local + coordinates. While this generally is more intuitive than surface + coordinates, it is especially desirable when using wp_viewport + or when a drawing library (like EGL) is unaware of buffer scale + and buffer transform. + + Note: Because buffer transformation changes and damage requests may + be interleaved in the protocol stream, it is impossible to determine + the actual mapping between surface and buffer damage until + wl_surface.commit time. Therefore, compositors wishing to take both + kinds of damage into account will have to accumulate damage from the + two requests separately and only transform from one to the other + after receiving the wl_surface.commit. + + + + + + + + + + + + The x and y arguments specify the location of the new pending + buffer's upper left corner, relative to the current buffer's upper + left corner, in surface-local coordinates. In other words, the + x and y, combined with the new surface size define in which + directions the surface's size changes. + + Surface location offset is double-buffered state, see + wl_surface.commit. + + This request is semantically equivalent to and the replaces the x and y + arguments in the wl_surface.attach request in wl_surface versions prior + to 5. See wl_surface.attach for details. + + + + + + + + + + This event indicates the preferred buffer scale for this surface. It is + sent whenever the compositor's preference changes. + + It is intended that scaling aware clients use this event to scale their + content and use wl_surface.set_buffer_scale to indicate the scale they + have rendered with. This allows clients to supply a higher detail + buffer. + + + + + + + This event indicates the preferred buffer transform for this surface. + It is sent whenever the compositor's preference changes. + + It is intended that transform aware clients use this event to apply the + transform to their content and use wl_surface.set_buffer_transform to + indicate the transform they have rendered with. + + + + + + + + A seat is a group of keyboards, pointer and touch devices. This + object is published as a global during start up, or when such a + device is hot plugged. A seat typically has a pointer and + maintains a keyboard focus and a pointer focus. + + + + + This is a bitmask of capabilities this seat has; if a member is + set, then it is present on the seat. + + + + + + + + + These errors can be emitted in response to wl_seat requests. + + + + + + + This is emitted whenever a seat gains or loses the pointer, + keyboard or touch capabilities. The argument is a capability + enum containing the complete set of capabilities this seat has. + + When the pointer capability is added, a client may create a + wl_pointer object using the wl_seat.get_pointer request. This object + will receive pointer events until the capability is removed in the + future. + + When the pointer capability is removed, a client should destroy the + wl_pointer objects associated with the seat where the capability was + removed, using the wl_pointer.release request. No further pointer + events will be received on these objects. + + In some compositors, if a seat regains the pointer capability and a + client has a previously obtained wl_pointer object of version 4 or + less, that object may start sending pointer events again. This + behavior is considered a misinterpretation of the intended behavior + and must not be relied upon by the client. wl_pointer objects of + version 5 or later must not send events if created before the most + recent event notifying the client of an added pointer capability. + + The above behavior also applies to wl_keyboard and wl_touch with the + keyboard and touch capabilities, respectively. + + + + + + + The ID provided will be initialized to the wl_pointer interface + for this seat. + + This request only takes effect if the seat has the pointer + capability, or has had the pointer capability in the past. + It is a protocol violation to issue this request on a seat that has + never had the pointer capability. The missing_capability error will + be sent in this case. + + + + + + + The ID provided will be initialized to the wl_keyboard interface + for this seat. + + This request only takes effect if the seat has the keyboard + capability, or has had the keyboard capability in the past. + It is a protocol violation to issue this request on a seat that has + never had the keyboard capability. The missing_capability error will + be sent in this case. + + + + + + + The ID provided will be initialized to the wl_touch interface + for this seat. + + This request only takes effect if the seat has the touch + capability, or has had the touch capability in the past. + It is a protocol violation to issue this request on a seat that has + never had the touch capability. The missing_capability error will + be sent in this case. + + + + + + + + + In a multi-seat configuration the seat name can be used by clients to + help identify which physical devices the seat represents. + + The seat name is a UTF-8 string with no convention defined for its + contents. Each name is unique among all wl_seat globals. The name is + only guaranteed to be unique for the current compositor instance. + + The same seat names are used for all clients. Thus, the name can be + shared across processes to refer to a specific wl_seat global. + + The name event is sent after binding to the seat global. This event is + only sent once per seat object, and the name does not change over the + lifetime of the wl_seat global. + + Compositors may re-use the same seat name if the wl_seat global is + destroyed and re-created later. + + + + + + + + + Using this request a client can tell the server that it is not going to + use the seat object anymore. + + + + + + + + The wl_pointer interface represents one or more input devices, + such as mice, which control the pointer location and pointer_focus + of a seat. + + The wl_pointer interface generates motion, enter and leave + events for the surfaces that the pointer is located over, + and button and axis events for button presses, button releases + and scrolling. + + + + + + + + + Set the pointer surface, i.e., the surface that contains the + pointer image (cursor). This request gives the surface the role + of a cursor. If the surface already has another role, it raises + a protocol error. + + The cursor actually changes only if the pointer + focus for this device is one of the requesting client's surfaces + or the surface parameter is the current pointer surface. If + there was a previous surface set with this request it is + replaced. If surface is NULL, the pointer image is hidden. + + The parameters hotspot_x and hotspot_y define the position of + the pointer surface relative to the pointer location. Its + top-left corner is always at (x, y) - (hotspot_x, hotspot_y), + where (x, y) are the coordinates of the pointer location, in + surface-local coordinates. + + On surface.attach requests to the pointer surface, hotspot_x + and hotspot_y are decremented by the x and y parameters + passed to the request. Attach must be confirmed by + wl_surface.commit as usual. + + The hotspot can also be updated by passing the currently set + pointer surface to this request with new values for hotspot_x + and hotspot_y. + + The input region is ignored for wl_surfaces with the role of + a cursor. When the use as a cursor ends, the wl_surface is + unmapped. + + The serial parameter must match the latest wl_pointer.enter + serial number sent to the client. Otherwise the request will be + ignored. + + + + + + + + + + Notification that this seat's pointer is focused on a certain + surface. + + When a seat's focus enters a surface, the pointer image + is undefined and a client should respond to this event by setting + an appropriate pointer image with the set_cursor request. + + + + + + + + + + Notification that this seat's pointer is no longer focused on + a certain surface. + + The leave notification is sent before the enter notification + for the new focus. + + + + + + + + Notification of pointer location change. The arguments + surface_x and surface_y are the location relative to the + focused surface. + + + + + + + + + Describes the physical state of a button that produced the button + event. + + + + + + + + Mouse button click and release notifications. + + The location of the click is given by the last motion or + enter event. + The time argument is a timestamp with millisecond + granularity, with an undefined base. + + The button is a button code as defined in the Linux kernel's + linux/input-event-codes.h header file, e.g. BTN_LEFT. + + Any 16-bit button code value is reserved for future additions to the + kernel's event code list. All other button codes above 0xFFFF are + currently undefined but may be used in future versions of this + protocol. + + + + + + + + + + Describes the axis types of scroll events. + + + + + + + + Scroll and other axis notifications. + + For scroll events (vertical and horizontal scroll axes), the + value parameter is the length of a vector along the specified + axis in a coordinate space identical to those of motion events, + representing a relative movement along the specified axis. + + For devices that support movements non-parallel to axes multiple + axis events will be emitted. + + When applicable, for example for touch pads, the server can + choose to emit scroll events where the motion vector is + equivalent to a motion event vector. + + When applicable, a client can transform its content relative to the + scroll distance. + + + + + + + + + + + Using this request a client can tell the server that it is not going to + use the pointer object anymore. + + This request destroys the pointer proxy object, so clients must not call + wl_pointer_destroy() after using this request. + + + + + + + + Indicates the end of a set of events that logically belong together. + A client is expected to accumulate the data in all events within the + frame before proceeding. + + All wl_pointer events before a wl_pointer.frame event belong + logically together. For example, in a diagonal scroll motion the + compositor will send an optional wl_pointer.axis_source event, two + wl_pointer.axis events (horizontal and vertical) and finally a + wl_pointer.frame event. The client may use this information to + calculate a diagonal vector for scrolling. + + When multiple wl_pointer.axis events occur within the same frame, + the motion vector is the combined motion of all events. + When a wl_pointer.axis and a wl_pointer.axis_stop event occur within + the same frame, this indicates that axis movement in one axis has + stopped but continues in the other axis. + When multiple wl_pointer.axis_stop events occur within the same + frame, this indicates that these axes stopped in the same instance. + + A wl_pointer.frame event is sent for every logical event group, + even if the group only contains a single wl_pointer event. + Specifically, a client may get a sequence: motion, frame, button, + frame, axis, frame, axis_stop, frame. + + The wl_pointer.enter and wl_pointer.leave events are logical events + generated by the compositor and not the hardware. These events are + also grouped by a wl_pointer.frame. When a pointer moves from one + surface to another, a compositor should group the + wl_pointer.leave event within the same wl_pointer.frame. + However, a client must not rely on wl_pointer.leave and + wl_pointer.enter being in the same wl_pointer.frame. + Compositor-specific policies may require the wl_pointer.leave and + wl_pointer.enter event being split across multiple wl_pointer.frame + groups. + + + + + + Describes the source types for axis events. This indicates to the + client how an axis event was physically generated; a client may + adjust the user interface accordingly. For example, scroll events + from a "finger" source may be in a smooth coordinate space with + kinetic scrolling whereas a "wheel" source may be in discrete steps + of a number of lines. + + The "continuous" axis source is a device generating events in a + continuous coordinate space, but using something other than a + finger. One example for this source is button-based scrolling where + the vertical motion of a device is converted to scroll events while + a button is held down. + + The "wheel tilt" axis source indicates that the actual device is a + wheel but the scroll event is not caused by a rotation but a + (usually sideways) tilt of the wheel. + + + + + + + + + + Source information for scroll and other axes. + + This event does not occur on its own. It is sent before a + wl_pointer.frame event and carries the source information for + all events within that frame. + + The source specifies how this event was generated. If the source is + wl_pointer.axis_source.finger, a wl_pointer.axis_stop event will be + sent when the user lifts the finger off the device. + + If the source is wl_pointer.axis_source.wheel, + wl_pointer.axis_source.wheel_tilt or + wl_pointer.axis_source.continuous, a wl_pointer.axis_stop event may + or may not be sent. Whether a compositor sends an axis_stop event + for these sources is hardware-specific and implementation-dependent; + clients must not rely on receiving an axis_stop event for these + scroll sources and should treat scroll sequences from these scroll + sources as unterminated by default. + + This event is optional. If the source is unknown for a particular + axis event sequence, no event is sent. + Only one wl_pointer.axis_source event is permitted per frame. + + The order of wl_pointer.axis_discrete and wl_pointer.axis_source is + not guaranteed. + + + + + + + Stop notification for scroll and other axes. + + For some wl_pointer.axis_source types, a wl_pointer.axis_stop event + is sent to notify a client that the axis sequence has terminated. + This enables the client to implement kinetic scrolling. + See the wl_pointer.axis_source documentation for information on when + this event may be generated. + + Any wl_pointer.axis events with the same axis_source after this + event should be considered as the start of a new axis motion. + + The timestamp is to be interpreted identical to the timestamp in the + wl_pointer.axis event. The timestamp value may be the same as a + preceding wl_pointer.axis event. + + + + + + + + Discrete step information for scroll and other axes. + + This event carries the axis value of the wl_pointer.axis event in + discrete steps (e.g. mouse wheel clicks). + + This event is deprecated with wl_pointer version 8 - this event is not + sent to clients supporting version 8 or later. + + This event does not occur on its own, it is coupled with a + wl_pointer.axis event that represents this axis value on a + continuous scale. The protocol guarantees that each axis_discrete + event is always followed by exactly one axis event with the same + axis number within the same wl_pointer.frame. Note that the protocol + allows for other events to occur between the axis_discrete and + its coupled axis event, including other axis_discrete or axis + events. A wl_pointer.frame must not contain more than one axis_discrete + event per axis type. + + This event is optional; continuous scrolling devices + like two-finger scrolling on touchpads do not have discrete + steps and do not generate this event. + + The discrete value carries the directional information. e.g. a value + of -2 is two steps towards the negative direction of this axis. + + The axis number is identical to the axis number in the associated + axis event. + + The order of wl_pointer.axis_discrete and wl_pointer.axis_source is + not guaranteed. + + + + + + + + Discrete high-resolution scroll information. + + This event carries high-resolution wheel scroll information, + with each multiple of 120 representing one logical scroll step + (a wheel detent). For example, an axis_value120 of 30 is one quarter of + a logical scroll step in the positive direction, a value120 of + -240 are two logical scroll steps in the negative direction within the + same hardware event. + Clients that rely on discrete scrolling should accumulate the + value120 to multiples of 120 before processing the event. + + The value120 must not be zero. + + This event replaces the wl_pointer.axis_discrete event in clients + supporting wl_pointer version 8 or later. + + Where a wl_pointer.axis_source event occurs in the same + wl_pointer.frame, the axis source applies to this event. + + The order of wl_pointer.axis_value120 and wl_pointer.axis_source is + not guaranteed. + + + + + + + + + + This specifies the direction of the physical motion that caused a + wl_pointer.axis event, relative to the wl_pointer.axis direction. + + + + + + + + Relative directional information of the entity causing the axis + motion. + + For a wl_pointer.axis event, the wl_pointer.axis_relative_direction + event specifies the movement direction of the entity causing the + wl_pointer.axis event. For example: + - if a user's fingers on a touchpad move down and this + causes a wl_pointer.axis vertical_scroll down event, the physical + direction is 'identical' + - if a user's fingers on a touchpad move down and this causes a + wl_pointer.axis vertical_scroll up scroll up event ('natural + scrolling'), the physical direction is 'inverted'. + + A client may use this information to adjust scroll motion of + components. Specifically, enabling natural scrolling causes the + content to change direction compared to traditional scrolling. + Some widgets like volume control sliders should usually match the + physical direction regardless of whether natural scrolling is + active. This event enables clients to match the scroll direction of + a widget to the physical direction. + + This event does not occur on its own, it is coupled with a + wl_pointer.axis event that represents this axis value. + The protocol guarantees that each axis_relative_direction event is + always followed by exactly one axis event with the same + axis number within the same wl_pointer.frame. Note that the protocol + allows for other events to occur between the axis_relative_direction + and its coupled axis event. + + The axis number is identical to the axis number in the associated + axis event. + + The order of wl_pointer.axis_relative_direction, + wl_pointer.axis_discrete and wl_pointer.axis_source is not + guaranteed. + + + + + + + + + The wl_keyboard interface represents one or more keyboards + associated with a seat. + + + + + This specifies the format of the keymap provided to the + client with the wl_keyboard.keymap event. + + + + + + + + This event provides a file descriptor to the client which can be + memory-mapped in read-only mode to provide a keyboard mapping + description. + + From version 7 onwards, the fd must be mapped with MAP_PRIVATE by + the recipient, as MAP_SHARED may fail. + + + + + + + + + Notification that this seat's keyboard focus is on a certain + surface. + + The compositor must send the wl_keyboard.modifiers event after this + event. + + + + + + + + + Notification that this seat's keyboard focus is no longer on + a certain surface. + + The leave notification is sent before the enter notification + for the new focus. + + After this event client must assume that all keys, including modifiers, + are lifted and also it must stop key repeating if there's some going on. + + + + + + + + Describes the physical state of a key that produced the key event. + + + + + + + + A key was pressed or released. + The time argument is a timestamp with millisecond + granularity, with an undefined base. + + The key is a platform-specific key code that can be interpreted + by feeding it to the keyboard mapping (see the keymap event). + + If this event produces a change in modifiers, then the resulting + wl_keyboard.modifiers event must be sent after this event. + + + + + + + + + + Notifies clients that the modifier and/or group state has + changed, and it should update its local state. + + + + + + + + + + + + + + + + + + + Informs the client about the keyboard's repeat rate and delay. + + This event is sent as soon as the wl_keyboard object has been created, + and is guaranteed to be received by the client before any key press + event. + + Negative values for either rate or delay are illegal. A rate of zero + will disable any repeating (regardless of the value of delay). + + This event can be sent later on as well with a new value if necessary, + so clients should continue listening for the event past the creation + of wl_keyboard. + + + + + + + + + The wl_touch interface represents a touchscreen + associated with a seat. + + Touch interactions can consist of one or more contacts. + For each contact, a series of events is generated, starting + with a down event, followed by zero or more motion events, + and ending with an up event. Events relating to the same + contact point can be identified by the ID of the sequence. + + + + + A new touch point has appeared on the surface. This touch point is + assigned a unique ID. Future events from this touch point reference + this ID. The ID ceases to be valid after a touch up event and may be + reused in the future. + + + + + + + + + + + + The touch point has disappeared. No further events will be sent for + this touch point and the touch point's ID is released and may be + reused in a future touch down event. + + + + + + + + + A touch point has changed coordinates. + + + + + + + + + + Indicates the end of a set of events that logically belong together. + A client is expected to accumulate the data in all events within the + frame before proceeding. + + A wl_touch.frame terminates at least one event but otherwise no + guarantee is provided about the set of events within a frame. A client + must assume that any state not updated in a frame is unchanged from the + previously known state. + + + + + + Sent if the compositor decides the touch stream is a global + gesture. No further events are sent to the clients from that + particular gesture. Touch cancellation applies to all touch points + currently active on this client's surface. The client is + responsible for finalizing the touch points, future touch points on + this surface may reuse the touch point ID. + + + + + + + + + + + + + + Sent when a touchpoint has changed its shape. + + This event does not occur on its own. It is sent before a + wl_touch.frame event and carries the new shape information for + any previously reported, or new touch points of that frame. + + Other events describing the touch point such as wl_touch.down, + wl_touch.motion or wl_touch.orientation may be sent within the + same wl_touch.frame. A client should treat these events as a single + logical touch point update. The order of wl_touch.shape, + wl_touch.orientation and wl_touch.motion is not guaranteed. + A wl_touch.down event is guaranteed to occur before the first + wl_touch.shape event for this touch ID but both events may occur within + the same wl_touch.frame. + + A touchpoint shape is approximated by an ellipse through the major and + minor axis length. The major axis length describes the longer diameter + of the ellipse, while the minor axis length describes the shorter + diameter. Major and minor are orthogonal and both are specified in + surface-local coordinates. The center of the ellipse is always at the + touchpoint location as reported by wl_touch.down or wl_touch.move. + + This event is only sent by the compositor if the touch device supports + shape reports. The client has to make reasonable assumptions about the + shape if it did not receive this event. + + + + + + + + + Sent when a touchpoint has changed its orientation. + + This event does not occur on its own. It is sent before a + wl_touch.frame event and carries the new shape information for + any previously reported, or new touch points of that frame. + + Other events describing the touch point such as wl_touch.down, + wl_touch.motion or wl_touch.shape may be sent within the + same wl_touch.frame. A client should treat these events as a single + logical touch point update. The order of wl_touch.shape, + wl_touch.orientation and wl_touch.motion is not guaranteed. + A wl_touch.down event is guaranteed to occur before the first + wl_touch.orientation event for this touch ID but both events may occur + within the same wl_touch.frame. + + The orientation describes the clockwise angle of a touchpoint's major + axis to the positive surface y-axis and is normalized to the -180 to + +180 degree range. The granularity of orientation depends on the touch + device, some devices only support binary rotation values between 0 and + 90 degrees. + + This event is only sent by the compositor if the touch device supports + orientation reports. + + + + + + + + + An output describes part of the compositor geometry. The + compositor works in the 'compositor coordinate system' and an + output corresponds to a rectangular area in that space that is + actually visible. This typically corresponds to a monitor that + displays part of the compositor space. This object is published + as global during start up, or when a monitor is hotplugged. + + + + + This enumeration describes how the physical + pixels on an output are laid out. + + + + + + + + + + + + This describes the transform that a compositor will apply to a + surface to compensate for the rotation or mirroring of an + output device. + + The flipped values correspond to an initial flip around a + vertical axis followed by rotation. + + The purpose is mainly to allow clients to render accordingly and + tell the compositor, so that for fullscreen surfaces, the + compositor will still be able to scan out directly from client + surfaces. + + + + + + + + + + + + + + The geometry event describes geometric properties of the output. + The event is sent when binding to the output object and whenever + any of the properties change. + + The physical size can be set to zero if it doesn't make sense for this + output (e.g. for projectors or virtual outputs). + + The geometry event will be followed by a done event (starting from + version 2). + + Note: wl_output only advertises partial information about the output + position and identification. Some compositors, for instance those not + implementing a desktop-style output layout or those exposing virtual + outputs, might fake this information. Instead of using x and y, clients + should use xdg_output.logical_position. Instead of using make and model, + clients should use name and description. + + + + + + + + + + + + + + These flags describe properties of an output mode. + They are used in the flags bitfield of the mode event. + + + + + + + + The mode event describes an available mode for the output. + + The event is sent when binding to the output object and there + will always be one mode, the current mode. The event is sent + again if an output changes mode, for the mode that is now + current. In other words, the current mode is always the last + mode that was received with the current flag set. + + Non-current modes are deprecated. A compositor can decide to only + advertise the current mode and never send other modes. Clients + should not rely on non-current modes. + + The size of a mode is given in physical hardware units of + the output device. This is not necessarily the same as + the output size in the global compositor space. For instance, + the output may be scaled, as described in wl_output.scale, + or transformed, as described in wl_output.transform. Clients + willing to retrieve the output size in the global compositor + space should use xdg_output.logical_size instead. + + The vertical refresh rate can be set to zero if it doesn't make + sense for this output (e.g. for virtual outputs). + + The mode event will be followed by a done event (starting from + version 2). + + Clients should not use the refresh rate to schedule frames. Instead, + they should use the wl_surface.frame event or the presentation-time + protocol. + + Note: this information is not always meaningful for all outputs. Some + compositors, such as those exposing virtual outputs, might fake the + refresh rate or the size. + + + + + + + + + + + + This event is sent after all other properties have been + sent after binding to the output object and after any + other property changes done after that. This allows + changes to the output properties to be seen as + atomic, even if they happen via multiple events. + + + + + + This event contains scaling geometry information + that is not in the geometry event. It may be sent after + binding the output object or if the output scale changes + later. If it is not sent, the client should assume a + scale of 1. + + A scale larger than 1 means that the compositor will + automatically scale surface buffers by this amount + when rendering. This is used for very high resolution + displays where applications rendering at the native + resolution would be too small to be legible. + + It is intended that scaling aware clients track the + current output of a surface, and if it is on a scaled + output it should use wl_surface.set_buffer_scale with + the scale of the output. That way the compositor can + avoid scaling the surface, and the client can supply + a higher detail image. + + The scale event will be followed by a done event. + + + + + + + + + Using this request a client can tell the server that it is not going to + use the output object anymore. + + + + + + + + Many compositors will assign user-friendly names to their outputs, show + them to the user, allow the user to refer to an output, etc. The client + may wish to know this name as well to offer the user similar behaviors. + + The name is a UTF-8 string with no convention defined for its contents. + Each name is unique among all wl_output globals. The name is only + guaranteed to be unique for the compositor instance. + + The same output name is used for all clients for a given wl_output + global. Thus, the name can be shared across processes to refer to a + specific wl_output global. + + The name is not guaranteed to be persistent across sessions, thus cannot + be used to reliably identify an output in e.g. configuration files. + + Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc. However, do + not assume that the name is a reflection of an underlying DRM connector, + X11 connection, etc. + + The name event is sent after binding the output object. This event is + only sent once per output object, and the name does not change over the + lifetime of the wl_output global. + + Compositors may re-use the same output name if the wl_output global is + destroyed and re-created later. Compositors should avoid re-using the + same name if possible. + + The name event will be followed by a done event. + + + + + + + Many compositors can produce human-readable descriptions of their + outputs. The client may wish to know this description as well, e.g. for + output selection purposes. + + The description is a UTF-8 string with no convention defined for its + contents. The description is not guaranteed to be unique among all + wl_output globals. Examples might include 'Foocorp 11" Display' or + 'Virtual X11 output via :1'. + + The description event is sent after binding the output object and + whenever the description changes. The description is optional, and may + not be sent at all. + + The description event will be followed by a done event. + + + + + + + + A region object describes an area. + + Region objects are used to describe the opaque and input + regions of a surface. + + + + + Destroy the region. This will invalidate the object ID. + + + + + + Add the specified rectangle to the region. + + + + + + + + + + Subtract the specified rectangle from the region. + + + + + + + + + + + The global interface exposing sub-surface compositing capabilities. + A wl_surface, that has sub-surfaces associated, is called the + parent surface. Sub-surfaces can be arbitrarily nested and create + a tree of sub-surfaces. + + The root surface in a tree of sub-surfaces is the main + surface. The main surface cannot be a sub-surface, because + sub-surfaces must always have a parent. + + A main surface with its sub-surfaces forms a (compound) window. + For window management purposes, this set of wl_surface objects is + to be considered as a single window, and it should also behave as + such. + + The aim of sub-surfaces is to offload some of the compositing work + within a window from clients to the compositor. A prime example is + a video player with decorations and video in separate wl_surface + objects. This should allow the compositor to pass YUV video buffer + processing to dedicated overlay hardware when possible. + + + + + Informs the server that the client will not be using this + protocol object anymore. This does not affect any other + objects, wl_subsurface objects included. + + + + + + + + + + + Create a sub-surface interface for the given surface, and + associate it with the given parent surface. This turns a + plain wl_surface into a sub-surface. + + The to-be sub-surface must not already have another role, and it + must not have an existing wl_subsurface object. Otherwise the + bad_surface protocol error is raised. + + Adding sub-surfaces to a parent is a double-buffered operation on the + parent (see wl_surface.commit). The effect of adding a sub-surface + becomes visible on the next time the state of the parent surface is + applied. + + The parent surface must not be one of the child surface's descendants, + and the parent must be different from the child surface, otherwise the + bad_parent protocol error is raised. + + This request modifies the behaviour of wl_surface.commit request on + the sub-surface, see the documentation on wl_subsurface interface. + + + + + + + + + + An additional interface to a wl_surface object, which has been + made a sub-surface. A sub-surface has one parent surface. A + sub-surface's size and position are not limited to that of the parent. + Particularly, a sub-surface is not automatically clipped to its + parent's area. + + A sub-surface becomes mapped, when a non-NULL wl_buffer is applied + and the parent surface is mapped. The order of which one happens + first is irrelevant. A sub-surface is hidden if the parent becomes + hidden, or if a NULL wl_buffer is applied. These rules apply + recursively through the tree of surfaces. + + The behaviour of a wl_surface.commit request on a sub-surface + depends on the sub-surface's mode. The possible modes are + synchronized and desynchronized, see methods + wl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized + mode caches the wl_surface state to be applied when the parent's + state gets applied, and desynchronized mode applies the pending + wl_surface state directly. A sub-surface is initially in the + synchronized mode. + + Sub-surfaces also have another kind of state, which is managed by + wl_subsurface requests, as opposed to wl_surface requests. This + state includes the sub-surface position relative to the parent + surface (wl_subsurface.set_position), and the stacking order of + the parent and its sub-surfaces (wl_subsurface.place_above and + .place_below). This state is applied when the parent surface's + wl_surface state is applied, regardless of the sub-surface's mode. + As the exception, set_sync and set_desync are effective immediately. + + The main surface can be thought to be always in desynchronized mode, + since it does not have a parent in the sub-surfaces sense. + + Even if a sub-surface is in desynchronized mode, it will behave as + in synchronized mode, if its parent surface behaves as in + synchronized mode. This rule is applied recursively throughout the + tree of surfaces. This means, that one can set a sub-surface into + synchronized mode, and then assume that all its child and grand-child + sub-surfaces are synchronized, too, without explicitly setting them. + + Destroying a sub-surface takes effect immediately. If you need to + synchronize the removal of a sub-surface to the parent surface update, + unmap the sub-surface first by attaching a NULL wl_buffer, update parent, + and then destroy the sub-surface. + + If the parent wl_surface object is destroyed, the sub-surface is + unmapped. + + + + + The sub-surface interface is removed from the wl_surface object + that was turned into a sub-surface with a + wl_subcompositor.get_subsurface request. The wl_surface's association + to the parent is deleted. The wl_surface is unmapped immediately. + + + + + + + + + + This schedules a sub-surface position change. + The sub-surface will be moved so that its origin (top left + corner pixel) will be at the location x, y of the parent surface + coordinate system. The coordinates are not restricted to the parent + surface area. Negative values are allowed. + + The scheduled coordinates will take effect whenever the state of the + parent surface is applied. When this happens depends on whether the + parent surface is in synchronized mode or not. See + wl_subsurface.set_sync and wl_subsurface.set_desync for details. + + If more than one set_position request is invoked by the client before + the commit of the parent surface, the position of a new request always + replaces the scheduled position from any previous request. + + The initial position is 0, 0. + + + + + + + + This sub-surface is taken from the stack, and put back just + above the reference surface, changing the z-order of the sub-surfaces. + The reference surface must be one of the sibling surfaces, or the + parent surface. Using any other surface, including this sub-surface, + will cause a protocol error. + + The z-order is double-buffered. Requests are handled in order and + applied immediately to a pending state. The final pending state is + copied to the active state the next time the state of the parent + surface is applied. When this happens depends on whether the parent + surface is in synchronized mode or not. See wl_subsurface.set_sync and + wl_subsurface.set_desync for details. + + A new sub-surface is initially added as the top-most in the stack + of its siblings and parent. + + + + + + + The sub-surface is placed just below the reference surface. + See wl_subsurface.place_above. + + + + + + + Change the commit behaviour of the sub-surface to synchronized + mode, also described as the parent dependent mode. + + In synchronized mode, wl_surface.commit on a sub-surface will + accumulate the committed state in a cache, but the state will + not be applied and hence will not change the compositor output. + The cached state is applied to the sub-surface immediately after + the parent surface's state is applied. This ensures atomic + updates of the parent and all its synchronized sub-surfaces. + Applying the cached state will invalidate the cache, so further + parent surface commits do not (re-)apply old state. + + See wl_subsurface for the recursive effect of this mode. + + + + + + Change the commit behaviour of the sub-surface to desynchronized + mode, also described as independent or freely running mode. + + In desynchronized mode, wl_surface.commit on a sub-surface will + apply the pending state directly, without caching, as happens + normally with a wl_surface. Calling wl_surface.commit on the + parent surface has no effect on the sub-surface's wl_surface + state. This mode allows a sub-surface to be updated on its own. + + If cached state exists when wl_surface.commit is called in + desynchronized mode, the pending state is added to the cached + state, and applied as a whole. This invalidates the cache. + + Note: even if a sub-surface is set to desynchronized, a parent + sub-surface may override it to behave as synchronized. For details, + see wl_subsurface. + + If a surface's parent surface behaves as desynchronized, then + the cached state is applied on set_desync. + + + + + diff --git a/zig-pkg/raylib-5.6.0-dev-whq8uL592gQ782dF95oci4S61qrNVYK3MhpUpNwFgZ1J/src/external/glfw/deps/wayland/xdg-activation-v1.xml b/zig-pkg/raylib-5.6.0-dev-whq8uL592gQ782dF95oci4S61qrNVYK3MhpUpNwFgZ1J/src/external/glfw/deps/wayland/xdg-activation-v1.xml new file mode 100644 index 0000000000..9adcc274ef --- /dev/null +++ b/zig-pkg/raylib-5.6.0-dev-whq8uL592gQ782dF95oci4S61qrNVYK3MhpUpNwFgZ1J/src/external/glfw/deps/wayland/xdg-activation-v1.xml @@ -0,0 +1,200 @@ + + + + + Copyright Β© 2020 Aleix Pol Gonzalez <aleixpol@kde.org> + Copyright Β© 2020 Carlos Garnacho <carlosg@gnome.org> + + Permission is hereby granted, free of charge, to any person obtaining a + copy of this software and associated documentation files (the "Software"), + to deal in the Software without restriction, including without limitation + the rights to use, copy, modify, merge, publish, distribute, sublicense, + and/or sell copies of the Software, and to permit persons to whom the + Software is furnished to do so, subject to the following conditions: + + The above copyright notice and this permission notice (including the next + paragraph) shall be included in all copies or substantial portions of the + Software. + + THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

An xdg_surface is + used as basis to define a role to a given surface, such as xdg_toplevel + or xdg_popup. It also manages functionality shared between xdg_surface + based surface roles. + + See the documentation of xdg_surface for more details about what an + xdg_surface is and how it is used. + + + + + + + + A client must respond to a ping event with a pong request or + the client may be deemed unresponsive. See xdg_wm_base.ping + and xdg_wm_base.error.unresponsive. + + + + + + + The ping event asks the client if it's still alive. Pass the + serial specified in the event back to the compositor by sending + a "pong" request back with the specified serial. See xdg_wm_base.pong. + + Compositors can use this to determine if the client is still + alive. It's unspecified what will happen if the client doesn't + respond to the ping request, or in what timeframe. Clients should + try to respond in a reasonable amount of time. The β€œunresponsive” + error is provided for compositors that wish to disconnect unresponsive + clients. + + A compositor is free to ping in any way it wants, but a client must + always respond to any xdg_wm_base object it created. + + + + + + + + The xdg_positioner provides a collection of rules for the placement of a + child surface relative to a parent surface. Rules can be defined to ensure + the child surface remains within the visible area's borders, and to + specify how the child surface changes its position, such as sliding along + an axis, or flipping around a rectangle. These positioner-created rules are + constrained by the requirement that a child surface must intersect with or + be at least partially adjacent to its parent surface. + + See the various requests for details about possible rules. + + At the time of the request, the compositor makes a copy of the rules + specified by the xdg_positioner. Thus, after the request is complete the + xdg_positioner object can be destroyed or reused; further changes to the + object will have no effect on previous usages. + + For an xdg_positioner object to be considered complete, it must have a + non-zero size set by set_size, and a non-zero anchor rectangle set by + set_anchor_rect. Passing an incomplete xdg_positioner object when + positioning a surface raises an invalid_positioner error. + + + + + + + + + Notify the compositor that the xdg_positioner will no longer be used. + + + + + + Set the size of the surface that is to be positioned with the positioner + object. The size is in surface-local coordinates and corresponds to the + window geometry. See xdg_surface.set_window_geometry. + + If a zero or negative size is set the invalid_input error is raised. + + + + + + + + Specify the anchor rectangle within the parent surface that the child + surface will be placed relative to. The rectangle is relative to the + window geometry as defined by xdg_surface.set_window_geometry of the + parent surface. + + When the xdg_positioner object is used to position a child surface, the + anchor rectangle may not extend outside the window geometry of the + positioned child's parent surface. + + If a negative size is set the invalid_input error is raised. + + + + + + + + + + + + + + + + + + + + + + Defines the anchor point for the anchor rectangle. The specified anchor + is used derive an anchor point that the child surface will be + positioned relative to. If a corner anchor is set (e.g. 'top_left' or + 'bottom_right'), the anchor point will be at the specified corner; + otherwise, the derived anchor point will be centered on the specified + edge, or in the center of the anchor rectangle if no edge is specified. + + + + + + + + + + + + + + + + + + + Defines in what direction a surface should be positioned, relative to + the anchor point of the parent surface. If a corner gravity is + specified (e.g. 'bottom_right' or 'top_left'), then the child surface + will be placed towards the specified gravity; otherwise, the child + surface will be centered over the anchor point on any axis that had no + gravity specified. If the gravity is not in the β€˜gravity’ enum, an + invalid_input error is raised. + + + + + + + The constraint adjustment value define ways the compositor will adjust + the position of the surface, if the unadjusted position would result + in the surface being partly constrained. + + Whether a surface is considered 'constrained' is left to the compositor + to determine. For example, the surface may be partly outside the + compositor's defined 'work area', thus necessitating the child surface's + position be adjusted until it is entirely inside the work area. + + The adjustments can be combined, according to a defined precedence: 1) + Flip, 2) Slide, 3) Resize. + + + + Don't alter the surface position even if it is constrained on some + axis, for example partially outside the edge of an output. + + + + + Slide the surface along the x axis until it is no longer constrained. + + First try to slide towards the direction of the gravity on the x axis + until either the edge in the opposite direction of the gravity is + unconstrained or the edge in the direction of the gravity is + constrained. + + Then try to slide towards the opposite direction of the gravity on the + x axis until either the edge in the direction of the gravity is + unconstrained or the edge in the opposite direction of the gravity is + constrained. + + + + + Slide the surface along the y axis until it is no longer constrained. + + First try to slide towards the direction of the gravity on the y axis + until either the edge in the opposite direction of the gravity is + unconstrained or the edge in the direction of the gravity is + constrained. + + Then try to slide towards the opposite direction of the gravity on the + y axis until either the edge in the direction of the gravity is + unconstrained or the edge in the opposite direction of the gravity is + constrained. + + + + + Invert the anchor and gravity on the x axis if the surface is + constrained on the x axis. For example, if the left edge of the + surface is constrained, the gravity is 'left' and the anchor is + 'left', change the gravity to 'right' and the anchor to 'right'. + + If the adjusted position also ends up being constrained, the resulting + position of the flip_x adjustment will be the one before the + adjustment. + + + + + Invert the anchor and gravity on the y axis if the surface is + constrained on the y axis. For example, if the bottom edge of the + surface is constrained, the gravity is 'bottom' and the anchor is + 'bottom', change the gravity to 'top' and the anchor to 'top'. + + The adjusted position is calculated given the original anchor + rectangle and offset, but with the new flipped anchor and gravity + values. + + If the adjusted position also ends up being constrained, the resulting + position of the flip_y adjustment will be the one before the + adjustment. + + + + + Resize the surface horizontally so that it is completely + unconstrained. + + + + + Resize the surface vertically so that it is completely unconstrained. + + + + + + + Specify how the window should be positioned if the originally intended + position caused the surface to be constrained, meaning at least + partially outside positioning boundaries set by the compositor. The + adjustment is set by constructing a bitmask describing the adjustment to + be made when the surface is constrained on that axis. + + If no bit for one axis is set, the compositor will assume that the child + surface should not change its position on that axis when constrained. + + If more than one bit for one axis is set, the order of how adjustments + are applied is specified in the corresponding adjustment descriptions. + + The default adjustment is none. + + + + + + + Specify the surface position offset relative to the position of the + anchor on the anchor rectangle and the anchor on the surface. For + example if the anchor of the anchor rectangle is at (x, y), the surface + has the gravity bottom|right, and the offset is (ox, oy), the calculated + surface position will be (x + ox, y + oy). The offset position of the + surface is the one used for constraint testing. See + set_constraint_adjustment. + + An example use case is placing a popup menu on top of a user interface + element, while aligning the user interface element of the parent surface + with some user interface element placed somewhere in the popup surface. + + + + + + + + + + When set reactive, the surface is reconstrained if the conditions used + for constraining changed, e.g. the parent window moved. + + If the conditions changed and the popup was reconstrained, an + xdg_popup.configure event is sent with updated geometry, followed by an + xdg_surface.configure event. + + + + + + Set the parent window geometry the compositor should use when + positioning the popup. The compositor may use this information to + determine the future state the popup should be constrained using. If + this doesn't match the dimension of the parent the popup is eventually + positioned against, the behavior is undefined. + + The arguments are given in the surface-local coordinate space. + + + + + + + + Set the serial of an xdg_surface.configure event this positioner will be + used in response to. The compositor may use this information together + with set_parent_size to determine what future state the popup should be + constrained using. + + + + + + + + An interface that may be implemented by a wl_surface, for + implementations that provide a desktop-style user interface. + + It provides a base set of functionality required to construct user + interface elements requiring management by the compositor, such as + toplevel windows, menus, etc. The types of functionality are split into + xdg_surface roles. + + Creating an xdg_surface does not set the role for a wl_surface. In order + to map an xdg_surface, the client must create a role-specific object + using, e.g., get_toplevel, get_popup. The wl_surface for any given + xdg_surface can have at most one role, and may not be assigned any role + not based on xdg_surface. + + A role must be assigned before any other requests are made to the + xdg_surface object. + + The client must call wl_surface.commit on the corresponding wl_surface + for the xdg_surface state to take effect. + + Creating an xdg_surface from a wl_surface which has a buffer attached or + committed is a client error, and any attempts by a client to attach or + manipulate a buffer prior to the first xdg_surface.configure call must + also be treated as errors. + + After creating a role-specific object and setting it up, the client must + perform an initial commit without any buffer attached. The compositor + will reply with initial wl_surface state such as + wl_surface.preferred_buffer_scale followed by an xdg_surface.configure + event. The client must acknowledge it and is then allowed to attach a + buffer to map the surface. + + Mapping an xdg_surface-based role surface is defined as making it + possible for the surface to be shown by the compositor. Note that + a mapped surface is not guaranteed to be visible once it is mapped. + + For an xdg_surface to be mapped by the compositor, the following + conditions must be met: + (1) the client has assigned an xdg_surface-based role to the surface + (2) the client has set and committed the xdg_surface state and the + role-dependent state to the surface + (3) the client has committed a buffer to the surface + + A newly-unmapped surface is considered to have met condition (1) out + of the 3 required conditions for mapping a surface if its role surface + has not been destroyed, i.e. the client must perform the initial commit + again before attaching a buffer. + + + + + + + + + + + + + + Destroy the xdg_surface object. An xdg_surface must only be destroyed + after its role object has been destroyed, otherwise + a defunct_role_object error is raised. + + + + + + This creates an xdg_toplevel object for the given xdg_surface and gives + the associated wl_surface the xdg_toplevel role. + + See the documentation of xdg_toplevel for more details about what an + xdg_toplevel is and how it is used. + + + + + + + This creates an xdg_popup object for the given xdg_surface and gives + the associated wl_surface the xdg_popup role. + + If null is passed as a parent, a parent surface must be specified using + some other protocol, before committing the initial state. + + See the documentation of xdg_popup for more details about what an + xdg_popup is and how it is used. + + + + + + + + + The window geometry of a surface is its "visible bounds" from the + user's perspective. Client-side decorations often have invisible + portions like drop-shadows which should be ignored for the + purposes of aligning, placing and constraining windows. + + The window geometry is double buffered, and will be applied at the + time wl_surface.commit of the corresponding wl_surface is called. + + When maintaining a position, the compositor should treat the (x, y) + coordinate of the window geometry as the top left corner of the window. + A client changing the (x, y) window geometry coordinate should in + general not alter the position of the window. + + Once the window geometry of the surface is set, it is not possible to + unset it, and it will remain the same until set_window_geometry is + called again, even if a new subsurface or buffer is attached. + + If never set, the value is the full bounds of the surface, + including any subsurfaces. This updates dynamically on every + commit. This unset is meant for extremely simple clients. + + The arguments are given in the surface-local coordinate space of + the wl_surface associated with this xdg_surface, and may extend outside + of the wl_surface itself to mark parts of the subsurface tree as part of + the window geometry. + + When applied, the effective window geometry will be the set window + geometry clamped to the bounding rectangle of the combined + geometry of the surface of the xdg_surface and the associated + subsurfaces. + + The effective geometry will not be recalculated unless a new call to + set_window_geometry is done and the new pending surface state is + subsequently applied. + + The width and height of the effective window geometry must be + greater than zero. Setting an invalid size will raise an + invalid_size error. + + + + + + + + + + When a configure event is received, if a client commits the + surface in response to the configure event, then the client + must make an ack_configure request sometime before the commit + request, passing along the serial of the configure event. + + For instance, for toplevel surfaces the compositor might use this + information to move a surface to the top left only when the client has + drawn itself for the maximized or fullscreen state. + + If the client receives multiple configure events before it + can respond to one, it only has to ack the last configure event. + Acking a configure event that was never sent raises an invalid_serial + error. + + A client is not required to commit immediately after sending + an ack_configure request - it may even ack_configure several times + before its next surface commit. + + A client may send multiple ack_configure requests before committing, but + only the last request sent before a commit indicates which configure + event the client really is responding to. + + Sending an ack_configure request consumes the serial number sent with + the request, as well as serial numbers sent by all configure events + sent on this xdg_surface prior to the configure event referenced by + the committed serial. + + It is an error to issue multiple ack_configure requests referencing a + serial from the same configure event, or to issue an ack_configure + request referencing a serial from a configure event issued before the + event identified by the last ack_configure request for the same + xdg_surface. Doing so will raise an invalid_serial error. + + + + + + + The configure event marks the end of a configure sequence. A configure + sequence is a set of one or more events configuring the state of the + xdg_surface, including the final xdg_surface.configure event. + + Where applicable, xdg_surface surface roles will during a configure + sequence extend this event as a latched state sent as events before the + xdg_surface.configure event. Such events should be considered to make up + a set of atomically applied configuration states, where the + xdg_surface.configure commits the accumulated state. + + Clients should arrange their surface for the new states, and then send + an ack_configure request with the serial sent in this configure event at + some point before committing the new surface. + + If the client receives multiple configure events before it can respond + to one, it is free to discard all but the last event it received. + + + + + + + + + This interface defines an xdg_surface role which allows a surface to, + among other things, set window-like properties such as maximize, + fullscreen, and minimize, set application-specific metadata like title and + id, and well as trigger user interactive operations such as interactive + resize and move. + + Unmapping an xdg_toplevel means that the surface cannot be shown + by the compositor until it is explicitly mapped again. + All active operations (e.g., move, resize) are canceled and all + attributes (e.g. title, state, stacking, ...) are discarded for + an xdg_toplevel surface when it is unmapped. The xdg_toplevel returns to + the state it had right after xdg_surface.get_toplevel. The client + can re-map the toplevel by perfoming a commit without any buffer + attached, waiting for a configure event and handling it as usual (see + xdg_surface description). + + Attaching a null buffer to a toplevel unmaps the surface. + + + + + This request destroys the role surface and unmaps the surface; + see "Unmapping" behavior in interface section for details. + + + + + + + + + + + + Set the "parent" of this surface. This surface should be stacked + above the parent surface and all other ancestor surfaces. + + Parent surfaces should be set on dialogs, toolboxes, or other + "auxiliary" surfaces, so that the parent is raised when the dialog + is raised. + + Setting a null parent for a child surface unsets its parent. Setting + a null parent for a surface which currently has no parent is a no-op. + + Only mapped surfaces can have child surfaces. Setting a parent which + is not mapped is equivalent to setting a null parent. If a surface + becomes unmapped, its children's parent is set to the parent of + the now-unmapped surface. If the now-unmapped surface has no parent, + its children's parent is unset. If the now-unmapped surface becomes + mapped again, its parent-child relationship is not restored. + + The parent toplevel must not be one of the child toplevel's + descendants, and the parent must be different from the child toplevel, + otherwise the invalid_parent protocol error is raised. + + + + + + + Set a short title for the surface. + + This string may be used to identify the surface in a task bar, + window list, or other user interface elements provided by the + compositor. + + The string must be encoded in UTF-8. + + + + + + + Set an application identifier for the surface. + + The app ID identifies the general class of applications to which + the surface belongs. The compositor can use this to group multiple + surfaces together, or to determine how to launch a new application. + + For D-Bus activatable applications, the app ID is used as the D-Bus + service name. + + The compositor shell will try to group application surfaces together + by their app ID. As a best practice, it is suggested to select app + ID's that match the basename of the application's .desktop file. + For example, "org.freedesktop.FooViewer" where the .desktop file is + "org.freedesktop.FooViewer.desktop". + + Like other properties, a set_app_id request can be sent after the + xdg_toplevel has been mapped to update the property. + + See the desktop-entry specification [0] for more details on + application identifiers and how they relate to well-known D-Bus + names and .desktop files. + + [0] https://standards.freedesktop.org/desktop-entry-spec/ + + + + + + + Clients implementing client-side decorations might want to show + a context menu when right-clicking on the decorations, giving the + user a menu that they can use to maximize or minimize the window. + + This request asks the compositor to pop up such a window menu at + the given position, relative to the local surface coordinates of + the parent surface. There are no guarantees as to what menu items + the window menu contains, or even if a window menu will be drawn + at all. + + This request must be used in response to some sort of user action + like a button press, key press, or touch down event. + + + + + + + + + + Start an interactive, user-driven move of the surface. + + This request must be used in response to some sort of user action + like a button press, key press, or touch down event. The passed + serial is used to determine the type of interactive move (touch, + pointer, etc). + + The server may ignore move requests depending on the state of + the surface (e.g. fullscreen or maximized), or if the passed serial + is no longer valid. + + If triggered, the surface will lose the focus of the device + (wl_pointer, wl_touch, etc) used for the move. It is up to the + compositor to visually indicate that the move is taking place, such as + updating a pointer cursor, during the move. There is no guarantee + that the device focus will return when the move is completed. + + + + + + + + These values are used to indicate which edge of a surface + is being dragged in a resize operation. + + + + + + + + + + + + + + + Start a user-driven, interactive resize of the surface. + + This request must be used in response to some sort of user action + like a button press, key press, or touch down event. The passed + serial is used to determine the type of interactive resize (touch, + pointer, etc). + + The server may ignore resize requests depending on the state of + the surface (e.g. fullscreen or maximized). + + If triggered, the client will receive configure events with the + "resize" state enum value and the expected sizes. See the "resize" + enum value for more details about what is required. The client + must also acknowledge configure events using "ack_configure". After + the resize is completed, the client will receive another "configure" + event without the resize state. + + If triggered, the surface also will lose the focus of the device + (wl_pointer, wl_touch, etc) used for the resize. It is up to the + compositor to visually indicate that the resize is taking place, + such as updating a pointer cursor, during the resize. There is no + guarantee that the device focus will return when the resize is + completed. + + The edges parameter specifies how the surface should be resized, and + is one of the values of the resize_edge enum. Values not matching + a variant of the enum will cause the invalid_resize_edge protocol error. + The compositor may use this information to update the surface position + for example when dragging the top left corner. The compositor may also + use this information to adapt its behavior, e.g. choose an appropriate + cursor image. + + + + + + + + + The different state values used on the surface. This is designed for + state values like maximized, fullscreen. It is paired with the + configure event to ensure that both the client and the compositor + setting the state can be synchronized. + + States set in this way are double-buffered. They will get applied on + the next commit. + + + + The surface is maximized. The window geometry specified in the configure + event must be obeyed by the client, or the xdg_wm_base.invalid_surface_state + error is raised. + + The client should draw without shadow or other + decoration outside of the window geometry. + + + + + The surface is fullscreen.

Whether this configure + actually sets the window maximized is subject to compositor policies. + The client must then update its content, drawing in the configured + state. The client must also acknowledge the configure when committing + the new content (see ack_configure). + + It is up to the compositor to decide how and where to maximize the + surface, for example which output and what region of the screen should + be used. + + If the surface was already maximized, the compositor will still emit + a configure event with the "maximized" state. + + If the surface is in a fullscreen state, this request has no direct + effect.

Whether this actually + un-maximizes the window is subject to compositor policies. + If available and applicable, the compositor will include the window + geometry dimensions the window had prior to being maximized in the + configure event. The client must then update its content, drawing it in + the configured state. The client must also acknowledge the configure + when committing the new content (see ack_configure). + + It is up to the compositor to position the surface after it was + unmaximized; usually the position the surface had before maximizing, if + applicable. + + If the surface was already not maximized, the compositor will still + emit a configure event without the "maximized" state. + + If the surface is in a fullscreen state, this request has no direct + effect. It may alter the state the surface is returned to when + unmaximized unless overridden by the compositor. + + + + + + Make the surface fullscreen. + + After requesting that the surface should be fullscreened, the + compositor will respond by emitting a configure event. Whether the + client is actually put into a fullscreen state is subject to compositor + policies. The client must also acknowledge the configure when + committing the new content (see ack_configure). + + The output passed by the request indicates the client's preference as + to which display it should be set fullscreen on. If this value is NULL, + it's up to the compositor to choose which display will be used to map + this surface. + + If the surface doesn't cover the whole output, the compositor will + position the surface in the center of the output and compensate with + with border fill covering the rest of the output. The content of the + border fill is undefined, but should be assumed to be in some way that + attempts to blend into the surrounding area (e.g. solid black). + + If the fullscreened surface is not opaque, the compositor must make + sure that other screen content not part of the same surface tree (made + up of subsurfaces, popups or similarly coupled surfaces) are not + visible below the fullscreened surface. + + + + + + + Make the surface no longer fullscreen. + + After requesting that the surface should be unfullscreened, the + compositor will respond by emitting a configure event. + Whether this actually removes the fullscreen state of the client is + subject to compositor policies. + + Making a surface unfullscreen sets states for the surface based on the following: + * the state(s) it may have had before becoming fullscreen + * any state(s) decided by the compositor + * any state(s) requested by the client while the surface was fullscreen + + The compositor may include the previous window geometry dimensions in + the configure event, if applicable. + + The client must also acknowledge the configure when committing the new + content (see ack_configure). + + + + + + Request that the compositor minimize your surface. There is no + way to know if the surface is currently minimized, nor is there + any way to unset minimization on this surface. + + If you are looking to throttle redrawing when minimized, please + instead use the wl_surface.frame event for this, as this will + also work with live previews on windows in Alt-Tab, Expose or + similar compositor features. + + + + + + This configure event asks the client to resize its toplevel surface or + to change its state. The configured state should not be applied + immediately. See xdg_surface.configure for details. + + The width and height arguments specify a hint to the window + about how its surface should be resized in window geometry + coordinates. See set_window_geometry. + + If the width or height arguments are zero, it means the client + should decide its own window dimension. This may happen when the + compositor needs to configure the state of the surface but doesn't + have any information about any previous or expected dimension. + + The states listed in the event specify how the width/height + arguments should be interpreted, and possibly how it should be + drawn. + + Clients must send an ack_configure in response to this event. See + xdg_surface.configure and xdg_surface.ack_configure for details. + + + + + + + + + The close event is sent by the compositor when the user + wants the surface to be closed. This should be equivalent to + the user clicking the close button in client-side decorations, + if your application has any. + + This is only a request that the user intends to close the + window. The client may choose to ignore this request, or show + a dialog to ask the user to save their data, etc. + + + + + + + + The configure_bounds event may be sent prior to a xdg_toplevel.configure + event to communicate the bounds a window geometry size is recommended + to constrain to. + + The passed width and height are in surface coordinate space. If width + and height are 0, it means bounds is unknown and equivalent to as if no + configure_bounds event was ever sent for this surface. + + The bounds can for example correspond to the size of a monitor excluding + any panels or other shell components, so that a surface isn't created in + a way that it cannot fit. + + The bounds may change at any point, and in such a case, a new + xdg_toplevel.configure_bounds will be sent, followed by + xdg_toplevel.configure and xdg_surface.configure. + + + + + + + + + + + + + + + + + This event advertises the capabilities supported by the compositor. If + a capability isn't supported, clients should hide or disable the UI + elements that expose this functionality. For instance, if the + compositor doesn't advertise support for minimized toplevels, a button + triggering the set_minimized request should not be displayed. + + The compositor will ignore requests it doesn't support. For instance, + a compositor which doesn't advertise support for minimized will ignore + set_minimized requests. + + Compositors must send this event once before the first + xdg_surface.configure event. When the capabilities change, compositors + must send this event again and then send an xdg_surface.configure + event. + + The configured state should not be applied immediately. See + xdg_surface.configure for details. + + The capabilities are sent as an array of 32-bit unsigned integers in + native endianness. + + + + + + + + A popup surface is a short-lived, temporary surface. It can be used to + implement for example menus, popovers, tooltips and other similar user + interface concepts. + + A popup can be made to take an explicit grab. See xdg_popup.grab for + details. + + When the popup is dismissed, a popup_done event will be sent out, and at + the same time the surface will be unmapped. See the xdg_popup.popup_done + event for details. + + Explicitly destroying the xdg_popup object will also dismiss the popup and + unmap the surface. Clients that want to dismiss the popup when another + surface of their own is clicked should dismiss the popup using the destroy + request. + + A newly created xdg_popup will be stacked on top of all previously created + xdg_popup surfaces associated with the same xdg_toplevel. + + The parent of an xdg_popup must be mapped (see the xdg_surface + description) before the xdg_popup itself. + + The client must call wl_surface.commit on the corresponding wl_surface + for the xdg_popup state to take effect. + + + + + + + + + This destroys the popup. Explicitly destroying the xdg_popup + object will also dismiss the popup, and unmap the surface. + + If this xdg_popup is not the "topmost" popup, the + xdg_wm_base.not_the_topmost_popup protocol error will be sent. + + + + + + This request makes the created popup take an explicit grab. An explicit + grab will be dismissed when the user dismisses the popup, or when the + client destroys the xdg_popup. This can be done by the user clicking + outside the surface, using the keyboard, or even locking the screen + through closing the lid or a timeout. + + If the compositor denies the grab, the popup will be immediately + dismissed. + + This request must be used in response to some sort of user action like a + button press, key press, or touch down event. The serial number of the + event should be passed as 'serial'. + + The parent of a grabbing popup must either be an xdg_toplevel surface or + another xdg_popup with an explicit grab. If the parent is another + xdg_popup it means that the popups are nested, with this popup now being + the topmost popup. + + Nested popups must be destroyed in the reverse order they were created + in, e.g. the only popup you are allowed to destroy at all times is the + topmost one. + + When compositors choose to dismiss a popup, they may dismiss every + nested grabbing popup as well. When a compositor dismisses popups, it + will follow the same dismissing order as required from the client. + + If the topmost grabbing popup is destroyed, the grab will be returned to + the parent of the popup, if that parent previously had an explicit grab. + + If the parent is a grabbing popup which has already been dismissed, this + popup will be immediately dismissed. If the parent is a popup that did + not take an explicit grab, an error will be raised. + + During a popup grab, the client owning the grab will receive pointer + and touch events for all their surfaces as normal (similar to an + "owner-events" grab in X11 parlance), while the top most grabbing popup + will always have keyboard focus. + + + + + + + + This event asks the popup surface to configure itself given the + configuration. The configured state should not be applied immediately. + See xdg_surface.configure for details. + + The x and y arguments represent the position the popup was placed at + given the xdg_positioner rule, relative to the upper left corner of the + window geometry of the parent surface. + + For version 2 or older, the configure event for an xdg_popup is only + ever sent once for the initial configuration. Starting with version 3, + it may be sent again if the popup is setup with an xdg_positioner with + set_reactive requested, or in response to xdg_popup.reposition requests. + + + + + + + + + + The popup_done event is sent out when a popup is dismissed by the + compositor. The client should destroy the xdg_popup object at this + point. + + + + + + + + Reposition an already-mapped popup. The popup will be placed given the + details in the passed xdg_positioner object, and a + xdg_popup.repositioned followed by xdg_popup.configure and + xdg_surface.configure will be emitted in response. Any parameters set + by the previous positioner will be discarded. + + The passed token will be sent in the corresponding + xdg_popup.repositioned event. The new popup position will not take + effect until the corresponding configure event is acknowledged by the + client. See xdg_popup.repositioned for details. The token itself is + opaque, and has no other special meaning. + + If multiple reposition requests are sent, the compositor may skip all + but the last one. + + If the popup is repositioned in response to a configure event for its + parent, the client should send an xdg_positioner.set_parent_configure + and possibly an xdg_positioner.set_parent_size request to allow the + compositor to properly constrain the popup. + + If the popup is repositioned together with a parent that is being + resized, but not in response to a configure event, the client should + send an xdg_positioner.set_parent_size request. + + + + + + + + The repositioned event is sent as part of a popup configuration + sequence, together with xdg_popup.configure and lastly + xdg_surface.configure to notify the completion of a reposition request. + + The repositioned event is to notify about the completion of a + xdg_popup.reposition request. The token argument is the token passed + in the xdg_popup.reposition request. + + Immediately after this event is emitted, xdg_popup.configure and + xdg_surface.configure will be sent with the updated size and position, + as well as a new configure serial. + + The client should optionally update the content of the popup, but must + acknowledge the new popup configuration for the new position to take + effect.

Introduction +=============== +To use miniaudio, just include "miniaudio.h" like any other header and add "miniaudio.c" to your +source tree. If you don't want to add it to your source tree you can compile and link to it like +any other library. Note that ABI compatibility is not guaranteed between versions, even with bug +fix releases, so take care if compiling as a shared object. + +miniaudio includes both low level and high level APIs. The low level API is good for those who want +to do all of their mixing themselves and only require a light weight interface to the underlying +audio device. The high level API is good for those who have complex mixing and effect requirements. + +In miniaudio, objects are transparent structures. Unlike many other libraries, there are no handles +to opaque objects which means you need to allocate memory for objects yourself. In the examples +presented in this documentation you will often see objects declared on the stack. You need to be +careful when translating these examples to your own code so that you don't accidentally declare +your objects on the stack and then cause them to become invalid once the function returns. In +addition, you must ensure the memory address of your objects remain the same throughout their +lifetime. You therefore cannot be making copies of your objects. + +A config/init pattern is used throughout the entire library. The idea is that you set up a config +object and pass that into the initialization routine. The advantage to this system is that the +config object can be initialized with logical defaults and new properties added to it without +breaking the API. The config object can be allocated on the stack and does not need to be +maintained after initialization of the corresponding object. + + +1.1. Low Level API +------------------ +The low level API gives you access to the raw audio data of an audio device. It supports playback, +capture, full-duplex and loopback (WASAPI only). You can enumerate over devices to determine which +physical device(s) you want to connect to. + +The low level API uses the concept of a "device" as the abstraction for physical devices. The idea +is that you choose a physical device to emit or capture audio from, and then move data to/from the +device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a +callback which you specify when initializing the device. + +When initializing the device you first need to configure it. The device configuration allows you to +specify things like the format of the data delivered via the callback, the size of the internal +buffer and the ID of the device you want to emit or capture audio from. + +Once you have the device configuration set up you can initialize the device. When initializing a +device you need to allocate memory for the device object beforehand. This gives the application +complete control over how the memory is allocated. In the example below we initialize a playback +device on the stack, but you could allocate it on the heap if that suits your situation better. + + ```c + void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) + { + // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both + // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than + // frameCount frames. + } + + int main() + { + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format. + config.playback.channels = 2; // Set to 0 to use the device's native channel count. + config.sampleRate = 48000; // Set to 0 to use the device's native sample rate. + config.dataCallback = data_callback; // This function will be called when miniaudio needs more data. + config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). + + ma_device device; + if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { + return -1; // Failed to initialize the device. + } + + ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. + + // Do something here. Probably your program's main loop. + + ma_device_uninit(&device); + return 0; + } + ``` + +In the example above, `data_callback()` is where audio data is written and read from the device. +The idea is in playback mode you cause sound to be emitted from the speakers by writing audio data +to the output buffer (`pOutput` in the example). In capture mode you read data from the input +buffer (`pInput`) to extract sound captured by the microphone. The `frameCount` parameter tells you +how many frames can be written to the output buffer and read from the input buffer. A "frame" is +one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 +samples: one for the left, one for the right. The channel count is defined by the device config. +The size in bytes of an individual sample is defined by the sample format which is also specified +in the device config. Multi-channel audio data is always interleaved, which means the samples for +each frame are stored next to each other in memory. For example, in a stereo stream the first pair +of samples will be the left and right samples for the first frame, the second pair of samples will +be the left and right samples for the second frame, etc. + +The configuration of the device is defined by the `ma_device_config` structure. The config object +is always initialized with `ma_device_config_init()`. It's important to always initialize the +config with this function as it initializes it with logical defaults and ensures your program +doesn't break when new members are added to the `ma_device_config` structure. The example above +uses a fairly simple and standard device configuration. The call to `ma_device_config_init()` takes +a single parameter, which is whether or not the device is a playback, capture, duplex or loopback +device (loopback devices are not supported on all backends). The `config.playback.format` member +sets the sample format which can be one of the following (all formats are native-endian): + + +---------------+----------------------------------------+---------------------------+ + | Symbol | Description | Range | + +---------------+----------------------------------------+---------------------------+ + | ma_format_f32 | 32-bit floating point | [-1, 1] | + | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | + | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | + | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | + | ma_format_u8 | 8-bit unsigned integer | [0, 255] | + +---------------+----------------------------------------+---------------------------+ + +The `config.playback.channels` member sets the number of channels to use with the device. The +channel count cannot exceed MA_MAX_CHANNELS. The `config.sampleRate` member sets the sample rate +(which must be the same for both playback and capture in full-duplex configurations). This is +usually set to 44100 or 48000, but can be set to anything. It's recommended to keep this between +8000 and 384000, however. + +Note that leaving the format, channel count and/or sample rate at their default values will result +in the internal device's native configuration being used which is useful if you want to avoid the +overhead of miniaudio's automatic data conversion. + +In addition to the sample format, channel count and sample rate, the data callback and user data +pointer are also set via the config. The user data pointer is not passed into the callback as a +parameter, but is instead set to the `pUserData` member of `ma_device` which you can access +directly since all miniaudio structures are transparent. + +Initializing the device is done with `ma_device_init()`. This will return a result code telling you +what went wrong, if anything. On success it will return `MA_SUCCESS`. After initialization is +complete the device will be in a stopped state. To start it, use `ma_device_start()`. +Uninitializing the device will stop it, which is what the example above does, but you can also stop +the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again. +Note that it's important to never stop or start the device from inside the callback. This will +result in a deadlock. Instead you set a variable or signal an event indicating that the device +needs to stop and handle it in a different thread. The following APIs must never be called inside +the callback: + + ```c + ma_device_init() + ma_device_init_ex() + ma_device_uninit() + ma_device_start() + ma_device_stop() + ``` + +You must never try uninitializing and reinitializing a device inside the callback. You must also +never try to stop and start it from inside the callback. There are a few other things you shouldn't +do in the callback depending on your requirements, however this isn't so much a thread-safety +thing, but rather a real-time processing thing which is beyond the scope of this introduction. + +The example above demonstrates the initialization of a playback device, but it works exactly the +same for capture. All you need to do is change the device type from `ma_device_type_playback` to +`ma_device_type_capture` when setting up the config, like so: + + ```c + ma_device_config config = ma_device_config_init(ma_device_type_capture); + config.capture.format = MY_FORMAT; + config.capture.channels = MY_CHANNEL_COUNT; + ``` + +In the data callback you just read from the input buffer (`pInput` in the example above) and leave +the output buffer alone (it will be set to NULL when the device type is set to +`ma_device_type_capture`). + +These are the available device types and how you should handle the buffers in the callback: + + +-------------------------+--------------------------------------------------------+ + | Device Type | Callback Behavior | + +-------------------------+--------------------------------------------------------+ + | ma_device_type_playback | Write to output buffer, leave input buffer untouched. | + | ma_device_type_capture | Read from input buffer, leave output buffer untouched. | + | ma_device_type_duplex | Read from input buffer, write to output buffer. | + | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. | + +-------------------------+--------------------------------------------------------+ + +You will notice in the example above that the sample format and channel count is specified +separately for playback and capture. This is to support different data formats between the playback +and capture devices in a full-duplex system. An example may be that you want to capture audio data +as a monaural stream (one channel), but output sound to a stereo speaker system. Note that if you +use different formats between playback and capture in a full-duplex configuration you will need to +convert the data yourself. There are functions available to help you do this which will be +explained later. + +The example above did not specify a physical device to connect to which means it will use the +operating system's default device. If you have multiple physical devices connected and you want to +use a specific one you will need to specify the device ID in the configuration, like so: + + ```c + config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device. + config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device. + ``` + +To retrieve the device ID you will need to perform device enumeration, however this requires the +use of a new concept called the "context". Conceptually speaking the context sits above the device. +There is one context to many devices. The purpose of the context is to represent the backend at a +more global level and to perform operations outside the scope of an individual device. Mainly it is +used for performing run-time linking against backend libraries, initializing backends and +enumerating devices. The example below shows how to enumerate devices. + + ```c + ma_context context; + if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) { + // Error. + } + + ma_device_info* pPlaybackInfos; + ma_uint32 playbackCount; + ma_device_info* pCaptureInfos; + ma_uint32 captureCount; + if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) { + // Error. + } + + // Loop over each device info and do something with it. Here we just print the name with their index. You may want + // to give the user the opportunity to choose which device they'd prefer. + for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) { + printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name); + } + + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id; + config.playback.format = MY_FORMAT; + config.playback.channels = MY_CHANNEL_COUNT; + config.sampleRate = MY_SAMPLE_RATE; + config.dataCallback = data_callback; + config.pUserData = pMyCustomData; + + ma_device device; + if (ma_device_init(&context, &config, &device) != MA_SUCCESS) { + // Error + } + + ... + + ma_device_uninit(&device); + ma_context_uninit(&context); + ``` + +The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. +The first parameter is a pointer to a list of `ma_backend` values which are used to override the +default backend priorities. When this is NULL, as in this example, miniaudio's default priorities +are used. The second parameter is the number of backends listed in the array pointed to by the +first parameter. The third parameter is a pointer to a `ma_context_config` object which can be +NULL, in which case defaults are used. The context configuration is used for setting the logging +callback, custom memory allocation callbacks, user-defined data and some backend-specific +configurations. + +Once the context has been initialized you can enumerate devices. In the example above we use the +simpler `ma_context_get_devices()`, however you can also use a callback for handling devices by +using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer +to a pointer that will, upon output, be set to a pointer to a buffer containing a list of +`ma_device_info` structures. You also provide a pointer to an unsigned integer that will receive +the number of items in the returned buffer. Do not free the returned buffers as their memory is +managed internally by miniaudio. + +The `ma_device_info` structure contains an `id` member which is the ID you pass to the device +config. It also contains the name of the device which is useful for presenting a list of devices +to the user via the UI. + +When creating your own context you will want to pass it to `ma_device_init()` when initializing the +device. Passing in NULL, like we do in the first example, will result in miniaudio creating the +context for you, which you don't want to do since you've already created a context. Note that +internally the context is only tracked by it's pointer which means you must not change the location +of the `ma_context` object. If this is an issue, consider using `malloc()` to allocate memory for +the context. + + +1.2. High Level API +------------------- +The high level API consists of three main parts: + + * Resource management for loading and streaming sounds. + * A node graph for advanced mixing and effect processing. + * A high level "engine" that wraps around the resource manager and node graph. + +The resource manager (`ma_resource_manager`) is used for loading sounds. It supports loading sounds +fully into memory and also streaming. It will also deal with reference counting for you which +avoids the same sound being loaded multiple times. + +The node graph is used for mixing and effect processing. The idea is that you connect a number of +nodes into the graph by connecting each node's outputs to another node's inputs. Each node can +implement its own effect. By chaining nodes together, advanced mixing and effect processing can +be achieved. + +The engine encapsulates both the resource manager and the node graph to create a simple, easy to +use high level API. The resource manager and node graph APIs are covered in more later sections of +this manual. + +The code below shows how you can initialize an engine using its default configuration. + + ```c + ma_result result; + ma_engine engine; + + result = ma_engine_init(NULL, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +This creates an engine instance which will initialize a device internally which you can access with +`ma_engine_get_device()`. It will also initialize a resource manager for you which can be accessed +with `ma_engine_get_resource_manager()`. The engine itself is a node graph (`ma_node_graph`) which +means you can pass a pointer to the engine object into any of the `ma_node_graph` APIs (with a +cast). Alternatively, you can use `ma_engine_get_node_graph()` instead of a cast. + +Note that all objects in miniaudio, including the `ma_engine` object in the example above, are +transparent structures. There are no handles to opaque structures in miniaudio which means you need +to be mindful of how you declare them. In the example above we are declaring it on the stack, but +this will result in the struct being invalidated once the function encapsulating it returns. If +allocating the engine on the heap is more appropriate, you can easily do so with a standard call +to `malloc()` or whatever heap allocation routine you like: + + ```c + ma_engine* pEngine = malloc(sizeof(*pEngine)); + ``` + +The `ma_engine` API uses the same config/init pattern used all throughout miniaudio. To configure +an engine, you can fill out a `ma_engine_config` object and pass it into the first parameter of +`ma_engine_init()`: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pResourceManager = &myCustomResourceManager; // <-- Initialized as some earlier stage. + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; + } + ``` + +This creates an engine instance using a custom config. In this particular example it's showing how +you can specify a custom resource manager rather than having the engine initialize one internally. +This is particularly useful if you want to have multiple engine's share the same resource manager. + +The engine must be uninitialized with `ma_engine_uninit()` when it's no longer needed. + +By default the engine will be started, but nothing will be playing because no sounds have been +initialized. The easiest but least flexible way of playing a sound is like so: + + ```c + ma_engine_play_sound(&engine, "my_sound.wav", NULL); + ``` + +This plays what miniaudio calls an "inline" sound. It plays the sound once, and then puts the +internal sound up for recycling. The last parameter is used to specify which sound group the sound +should be associated with which will be explained later. This particular way of playing a sound is +simple, but lacks flexibility and features. A more flexible way of playing a sound is to first +initialize a sound: + + ```c + ma_result result; + ma_sound sound; + + result = ma_sound_init_from_file(&engine, "my_sound.wav", 0, NULL, NULL, &sound); + if (result != MA_SUCCESS) { + return result; + } + + ma_sound_start(&sound); + ``` + +This returns a `ma_sound` object which represents a single instance of the specified sound file. If +you want to play the same file multiple times simultaneously, you need to create one sound for each +instance. + +Sounds should be uninitialized with `ma_sound_uninit()`. + +Sounds are not started by default. Start a sound with `ma_sound_start()` and stop it with +`ma_sound_stop()`. When a sound is stopped, it is not rewound to the start. Use +`ma_sound_seek_to_pcm_frame(&sound, 0)` to seek back to the start of a sound. By default, starting +and stopping sounds happens immediately, but sometimes it might be convenient to schedule the sound +to be started and/or stopped at a specific time. This can be done with the following functions: + + ```c + ma_sound_set_start_time_in_pcm_frames() + ma_sound_set_start_time_in_milliseconds() + ma_sound_set_stop_time_in_pcm_frames() + ma_sound_set_stop_time_in_milliseconds() + ``` + +The start/stop time needs to be specified based on the absolute timer which is controlled by the +engine. The current global time in PCM frames can be retrieved with +`ma_engine_get_time_in_pcm_frames()`. The engine's global time can be changed with +`ma_engine_set_time_in_pcm_frames()` for synchronization purposes if required. Note that scheduling +a start time still requires an explicit call to `ma_sound_start()` before anything will play: + + ```c + ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2); + ma_sound_start(&sound); + ``` + +The third parameter of `ma_sound_init_from_file()` is a set of flags that control how the sound be +loaded and a few options on which features should be enabled for that sound. By default, the sound +is synchronously loaded fully into memory straight from the file system without any kind of +decoding. If you want to decode the sound before storing it in memory, you need to specify the +`MA_SOUND_FLAG_DECODE` flag. This is useful if you want to incur the cost of decoding at an earlier +stage, such as a loading stage. Without this option, decoding will happen dynamically at mixing +time which might be too expensive on the audio thread. + +If you want to load the sound asynchronously, you can specify the `MA_SOUND_FLAG_ASYNC` flag. This +will result in `ma_sound_init_from_file()` returning quickly, but the sound will not start playing +until the sound has had some audio decoded. + +The fourth parameter is a pointer to sound group. A sound group is used as a mechanism to organise +sounds into groups which have their own effect processing and volume control. An example is a game +which might have separate groups for sfx, voice and music. Each of these groups have their own +independent volume control. Use `ma_sound_group_init()` or `ma_sound_group_init_ex()` to initialize +a sound group. + +Sounds and sound groups are nodes in the engine's node graph and can be plugged into any `ma_node` +API. This makes it possible to connect sounds and sound groups to effect nodes to produce complex +effect chains. + +A sound can have its volume changed with `ma_sound_set_volume()`. If you prefer decibel volume +control you can use `ma_volume_db_to_linear()` to convert from decibel representation to linear. + +Panning and pitching is supported with `ma_sound_set_pan()` and `ma_sound_set_pitch()`. If you know +a sound will never have its pitch changed with `ma_sound_set_pitch()` or via the doppler effect, +you can specify the `MA_SOUND_FLAG_NO_PITCH` flag when initializing the sound for an optimization. + +By default, sounds and sound groups have spatialization enabled. If you don't ever want to +spatialize your sounds, initialize the sound with the `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. The +spatialization model is fairly simple and is roughly on feature parity with OpenAL. HRTF and +environmental occlusion are not currently supported, but planned for the future. The supported +features include: + + * Sound and listener positioning and orientation with cones + * Attenuation models: none, inverse, linear and exponential + * Doppler effect + +Sounds can be faded in and out with `ma_sound_set_fade_in_pcm_frames()`. + +To check if a sound is currently playing, you can use `ma_sound_is_playing()`. To check if a sound +is at the end, use `ma_sound_at_end()`. Looping of a sound can be controlled with +`ma_sound_set_looping()`. Use `ma_sound_is_looping()` to check whether or not the sound is looping. + + + +2. Building +=========== +miniaudio should work cleanly out of the box without the need to download or install any +dependencies. See below for platform-specific details. + +This library has been designed to be added directly to your source tree which is the preferred way +of using it, but you can compile it as a normal library if that's your preference. Be careful if +compiling as a shared object because miniaudio is not ABI compatible between any release, including +bug fix releases. It's recommended you link statically. + +Note that GCC and Clang require `-msse2`, `-mavx2`, etc. for SIMD optimizations. + +If you get errors about undefined references to `__sync_val_compare_and_swap_8`, `__atomic_load_8`, +etc. you need to link with `-latomic`. + + +2.1. Windows +------------ +The Windows build should compile cleanly on all popular compilers without the need to configure any +include paths nor link to any libraries. + +The UWP build may require linking to mmdevapi.lib if you get errors about an unresolved external +symbol for `ActivateAudioInterfaceAsync()`. + + +2.2. macOS and iOS +------------------ +The macOS build should compile cleanly without the need to download any dependencies nor link to +any libraries or frameworks. The iOS build needs to be compiled as Objective-C and will need to +link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling +through the command line requires linking to `-lpthread` and `-lm`. + +Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's +notarization process. To fix this there are two options. The first is to compile with +`-DMA_NO_RUNTIME_LINKING` which in turn will require linking with +`-framework CoreFoundation -framework CoreAudio -framework AudioToolbox`. If you get errors about +AudioToolbox, try with `-framework AudioUnit` instead. You may get this when using older versions +of iOS. Alternatively, if you would rather keep using runtime linking you can add the following to +your entitlements.xcent file: + + ``` + com.apple.security.cs.allow-dyld-environment-variables + + com.apple.security.cs.allow-unsigned-executable-memory + + ``` + +See this discussion for more info: https://github.com/mackron/miniaudio/issues/203. + + +2.3. Linux +---------- +The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any +development packages. You may need to link with `-latomic` if you're compiling for 32-bit ARM. + + +2.4. BSD +-------- +The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses +sndio and FreeBSD uses OSS. You may need to link with `-latomic` if you're compiling for 32-bit +ARM. + + +2.5. Android +------------ +AAudio is the highest priority backend on Android. This should work out of the box without needing +any kind of compiler configuration. Support for AAudio starts with Android 8 which means older +versions will fall back to OpenSL|ES which requires API level 16+. + +There have been reports that the OpenSL|ES backend fails to initialize on some Android based +devices due to `dlopen()` failing to open "libOpenSLES.so". If this happens on your platform +you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES. + + +2.6. Emscripten +--------------- +The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. +You cannot use `-std=c*` compiler flags, nor `-ansi`. + +You can enable the use of AudioWorklets by defining `MA_ENABLE_AUDIO_WORKLETS` and then compiling +with the following options: + + -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY + +An example for compiling with AudioWorklet support might look like this: + + emcc program.c -o bin/program.html -DMA_ENABLE_AUDIO_WORKLETS -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY + +To run locally, you'll need to use emrun: + + emrun bin/program.html + + + +2.7.

Definitions +============== +This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity +in the use of terms throughout the audio space, so this section is intended to clarify how miniaudio +uses each term. + +3.1. Sample +----------- +A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit +floating point number. + +3.2. Frame / PCM Frame +---------------------- +A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 +samples, a mono frame is 1 sample, a 5.1 surround sound frame is 6 samples, etc. The terms "frame" +and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. +If ever miniaudio needs to refer to a compressed frame, such as a FLAC frame, it will always +clarify what it's referring to with something like "FLAC frame". + +3.3. Channel +------------ +A stream of monaural audio that is emitted from an individual speaker in a speaker system, or +received from an individual microphone in a microphone system. A stereo stream has two channels (a +left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio +systems refer to a channel as a complex audio stream that's mixed with other channels to produce +the final mix - this is completely different to miniaudio's use of the term "channel" and should +not be confused. + +3.4. Sample Rate +---------------- +The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number +of PCM frames that are processed per second. + +3.5. Formats +------------ +Throughout miniaudio you will see references to different sample formats: + + +---------------+----------------------------------------+---------------------------+ + | Symbol | Description | Range | + +---------------+----------------------------------------+---------------------------+ + | ma_format_f32 | 32-bit floating point | [-1, 1] | + | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | + | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | + | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | + | ma_format_u8 | 8-bit unsigned integer | [0, 255] | + +---------------+----------------------------------------+---------------------------+ + +All formats are native-endian. + + + +4. Data Sources +=============== +The data source abstraction in miniaudio is used for retrieving audio data from some source. A few +examples include `ma_decoder`, `ma_noise` and `ma_waveform`. You will need to be familiar with data +sources in order to make sense of some of the higher level concepts in miniaudio. + +The `ma_data_source` API is a generic interface for reading from a data source. Any object that +implements the data source interface can be plugged into any `ma_data_source` function. + +To read data from a data source: + + ```c + ma_result result; + ma_uint64 framesRead; + + result = ma_data_source_read_pcm_frames(pDataSource, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read data from the data source. + } + ``` + +If you don't need the number of frames that were successfully read you can pass in `NULL` to the +`pFramesRead` parameter. If this returns a value less than the number of frames requested it means +the end of the file has been reached. `MA_AT_END` will be returned only when the number of frames +read is 0. + +When calling any data source function, with the exception of `ma_data_source_init()` and +`ma_data_source_uninit()`, you can pass in any object that implements a data source. For example, +you could plug in a decoder like so: + + ```c + ma_result result; + ma_uint64 framesRead; + ma_decoder decoder; // <-- This would be initialized with `ma_decoder_init_*()`. + + result = ma_data_source_read_pcm_frames(&decoder, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read data from the decoder. + } + ``` + +If you want to seek forward you can pass in `NULL` to the `pFramesOut` parameter. Alternatively you +can use `ma_data_source_seek_pcm_frames()`. + +To seek to a specific PCM frame: + + ```c + result = ma_data_source_seek_to_pcm_frame(pDataSource, frameIndex); + if (result != MA_SUCCESS) { + return result; // Failed to seek to PCM frame. + } + ``` + +You can retrieve the total length of a data source in PCM frames, but note that some data sources +may not have the notion of a length, such as noise and waveforms, and others may just not have a +way of determining the length such as some decoders. To retrieve the length: + + ```c + ma_uint64 length; + + result = ma_data_source_get_length_in_pcm_frames(pDataSource, &length); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve the length. + } + ``` + +Care should be taken when retrieving the length of a data source where the underlying decoder is +pulling data from a data stream with an undefined length, such as internet radio or some kind of +broadcast. If you do this, `ma_data_source_get_length_in_pcm_frames()` may never return. + +The current position of the cursor in PCM frames can also be retrieved: + + ```c + ma_uint64 cursor; + + result = ma_data_source_get_cursor_in_pcm_frames(pDataSource, &cursor); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve the cursor. + } + ``` + +You will often need to know the data format that will be returned after reading. This can be +retrieved like so: + + ```c + ma_format format; + ma_uint32 channels; + ma_uint32 sampleRate; + ma_channel channelMap[MA_MAX_CHANNELS]; + + result = ma_data_source_get_data_format(pDataSource, &format, &channels, &sampleRate, channelMap, MA_MAX_CHANNELS); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve data format. + } + ``` + +If you do not need a specific data format property, just pass in NULL to the respective parameter. + +There may be cases where you want to implement something like a sound bank where you only want to +read data within a certain range of the underlying data. To do this you can use a range: + + ```c + result = ma_data_source_set_range_in_pcm_frames(pDataSource, rangeBegInFrames, rangeEndInFrames); + if (result != MA_SUCCESS) { + return result; // Failed to set the range. + } + ``` + +This is useful if you have a sound bank where many sounds are stored in the same file and you want +the data source to only play one of those sub-sounds. Note that once the range is set, everything +that takes a position, such as cursors and loop points, should always be relative to the start of +the range. When the range is set, any previously defined loop point will be reset. + +Custom loop points can also be used with data sources. By default, data sources will loop after +they reach the end of the data source, but if you need to loop at a specific location, you can do +the following: + + ```c + result = ma_data_source_set_loop_point_in_pcm_frames(pDataSource, loopBegInFrames, loopEndInFrames); + if (result != MA_SUCCESS) { + return result; // Failed to set the loop point. + } + ``` + +The loop point is relative to the current range. + +It's sometimes useful to chain data sources together so that a seamless transition can be achieved. +To do this, you can use chaining: + + ```c + ma_decoder decoder1; + ma_decoder decoder2; + + // ... initialize decoders with ma_decoder_init_*() ... + + result = ma_data_source_set_next(&decoder1, &decoder2); + if (result != MA_SUCCESS) { + return result; // Failed to set the next data source. + } + + result = ma_data_source_read_pcm_frames(&decoder1, pFramesOut, frameCount, pFramesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read from the decoder. + } + ``` + +In the example above we're using decoders. When reading from a chain, you always want to read from +the top level data source in the chain. In the example above, `decoder1` is the top level data +source in the chain. When `decoder1` reaches the end, `decoder2` will start seamlessly without any +gaps. + +Note that when looping is enabled, only the current data source will be looped. You can loop the +entire chain by linking in a loop like so: + + ```c + ma_data_source_set_next(&decoder1, &decoder2); // decoder1 -> decoder2 + ma_data_source_set_next(&decoder2, &decoder1); // decoder2 -> decoder1 (loop back to the start). + ``` + +Note that setting up chaining is not thread safe, so care needs to be taken if you're dynamically +changing links while the audio thread is in the middle of reading. + +Do not use `ma_decoder_seek_to_pcm_frame()` as a means to reuse a data source to play multiple +instances of the same sound simultaneously. This can be extremely inefficient depending on the type +of data source and can result in glitching due to subtle changes to the state of internal filters. +Instead, initialize multiple data sources for each instance. + + +4.1. Custom Data Sources +------------------------ +You can implement a custom data source by implementing the functions in `ma_data_source_vtable`. +Your custom object must have `ma_data_source_base` as it's first member: + + ```c + struct my_data_source + { + ma_data_source_base base; + ... + }; + ``` + +In your initialization routine, you need to call `ma_data_source_init()` in order to set up the +base object (`ma_data_source_base`): + + ```c + static ma_result my_data_source_read(ma_data_source* pDataSource, void* pFramesOut, ma_uint64 frameCount, ma_uint64* pFramesRead) + { + // Read data here. Output in the same format returned by my_data_source_get_data_format(). + } + + static ma_result my_data_source_seek(ma_data_source* pDataSource, ma_uint64 frameIndex) + { + // Seek to a specific PCM frame here. Return MA_NOT_IMPLEMENTED if seeking is not supported. + } + + static ma_result my_data_source_get_data_format(ma_data_source* pDataSource, ma_format* pFormat, ma_uint32* pChannels, ma_uint32* pSampleRate, ma_channel* pChannelMap, size_t channelMapCap) + { + // Return the format of the data here. + } + + static ma_result my_data_source_get_cursor(ma_data_source* pDataSource, ma_uint64* pCursor) + { + // Retrieve the current position of the cursor here. Return MA_NOT_IMPLEMENTED and set *pCursor to 0 if there is no notion of a cursor. + } + + static ma_result my_data_source_get_length(ma_data_source* pDataSource, ma_uint64* pLength) + { + // Retrieve the length in PCM frames here. Return MA_NOT_IMPLEMENTED and set *pLength to 0 if there is no notion of a length or if the length is unknown. + } + + static ma_data_source_vtable g_my_data_source_vtable = + { + my_data_source_read, + my_data_source_seek, + my_data_source_get_data_format, + my_data_source_get_cursor, + my_data_source_get_length + }; + + ma_result my_data_source_init(my_data_source* pMyDataSource) + { + ma_result result; + ma_data_source_config baseConfig; + + baseConfig = ma_data_source_config_init(); + baseConfig.vtable = &g_my_data_source_vtable; + + result = ma_data_source_init(&baseConfig, &pMyDataSource->base); + if (result != MA_SUCCESS) { + return result; + } + + // ... do the initialization of your custom data source here ... + + return MA_SUCCESS; + } + + void my_data_source_uninit(my_data_source* pMyDataSource) + { + // ... do the uninitialization of your custom data source here ... + + // You must uninitialize the base data source. + ma_data_source_uninit(&pMyDataSource->base); + } + ``` + +Note that `ma_data_source_init()` and `ma_data_source_uninit()` are never called directly outside +of the custom data source. It's up to the custom data source itself to call these within their own +init/uninit functions. + + + +5. Engine +========= +The `ma_engine` API is a high level API for managing and mixing sounds and effect processing. The +`ma_engine` object encapsulates a resource manager and a node graph, both of which will be +explained in more detail later. + +Sounds are called `ma_sound` and are created from an engine. Sounds can be associated with a mixing +group called `ma_sound_group` which are also created from the engine. Both `ma_sound` and +`ma_sound_group` objects are nodes within the engine's node graph. + +When the engine is initialized, it will normally create a device internally. If you would rather +manage the device yourself, you can do so and just pass a pointer to it via the engine config when +you initialize the engine. You can also just use the engine without a device, which again can be +configured via the engine config. + +The most basic way to initialize the engine is with a default config, like so: + + ```c + ma_result result; + ma_engine engine; + + result = ma_engine_init(NULL, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +This will result in the engine initializing a playback device using the operating system's default +device. This will be sufficient for many use cases, but if you need more flexibility you'll want to +configure the engine with an engine config: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pDevice = &myDevice; + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +In the example above we're passing in a pre-initialized device. Since the caller is the one in +control of the device's data callback, it's their responsibility to manually call +`ma_engine_read_pcm_frames()` from inside their data callback: + + ```c + void playback_data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) + { + ma_engine_read_pcm_frames(&g_Engine, pOutput, frameCount, NULL); + } + ``` + +You can also use the engine independent of a device entirely: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.noDevice = MA_TRUE; + engineConfig.channels = 2; // Must be set when not using a device. + engineConfig.sampleRate = 48000; // Must be set when not using a device. + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +Note that when you're not using a device, you must set the channel count and sample rate in the +config or else miniaudio won't know what to use (miniaudio will use the device to determine this +normally). When not using a device, you need to use `ma_engine_read_pcm_frames()` to process audio +data from the engine. This kind of setup is useful if you want to do something like offline +processing or want to use a different audio system for playback such as SDL. + +When a sound is loaded it goes through a resource manager. By default the engine will initialize a +resource manager internally, but you can also specify a pre-initialized resource manager: + + ```c + ma_result result; + ma_engine engine1; + ma_engine engine2; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pResourceManager = &myResourceManager; + + ma_engine_init(&engineConfig, &engine1); + ma_engine_init(&engineConfig, &engine2); + ``` + +In this example we are initializing two engines, both of which are sharing the same resource +manager. This is especially useful for saving memory when loading the same file across multiple +engines. If you were not to use a shared resource manager, each engine instance would use their own +which would result in any sounds that are used between both engine's being loaded twice. By using +a shared resource manager, it would only be loaded once. Using multiple engine's is useful when you +need to output to multiple playback devices, such as in a local multiplayer game where each player +is using their own set of headphones. + +By default an engine will be in a started state. To make it so the engine is not automatically +started you can configure it as such: + + ```c + engineConfig.noAutoStart = MA_TRUE; + + // The engine will need to be started manually. + ma_engine_start(&engine); + + // Later on the engine can be stopped with ma_engine_stop(). + ma_engine_stop(&engine); + ``` + +The concept of starting or stopping an engine is only relevant when using the engine with a +device. Attempting to start or stop an engine that is not associated with a device will result in +`MA_INVALID_OPERATION`. + +The master volume of the engine can be controlled with `ma_engine_set_volume()` which takes a +linear scale, with 0 resulting in silence and anything above 1 resulting in amplification. If you +prefer decibel based volume control, use `ma_volume_db_to_linear()` to convert from dB to linear. + +When a sound is spatialized, it is done so relative to a listener. An engine can be configured to +have multiple listeners which can be configured via the config: + + ```c + engineConfig.listenerCount = 2; + ``` + +The maximum number of listeners is restricted to `MA_ENGINE_MAX_LISTENERS`. By default, when a +sound is spatialized, it will be done so relative to the closest listener. You can also pin a sound +to a specific listener which will be explained later. Listener's have a position, direction, cone, +and velocity (for doppler effect). A listener is referenced by an index, the meaning of which is up +to the caller (the index is 0 based and cannot go beyond the listener count, minus 1). The +position, direction and velocity are all specified in absolute terms: + + ```c + ma_engine_listener_set_position(&engine, listenerIndex, worldPosX, worldPosY, worldPosZ); + ``` + +The direction of the listener represents it's forward vector. The listener's up vector can also be +specified and defaults to +1 on the Y axis. + + ```c + ma_engine_listener_set_direction(&engine, listenerIndex, forwardX, forwardY, forwardZ); + ma_engine_listener_set_world_up(&engine, listenerIndex, 0, 1, 0); + ``` + +The engine supports directional attenuation. The listener can have a cone the controls how sound is +attenuated based on the listener's direction. When a sound is between the inner and outer cones, it +will be attenuated between 1 and the cone's outer gain: + + ```c + ma_engine_listener_set_cone(&engine, listenerIndex, innerAngleInRadians, outerAngleInRadians, outerGain); + ``` + +When a sound is inside the inner code, no directional attenuation is applied. When the sound is +outside of the outer cone, the attenuation will be set to `outerGain` in the example above. When +the sound is in between the inner and outer cones, the attenuation will be interpolated between 1 +and the outer gain. + +The engine's coordinate system follows the OpenGL coordinate system where positive X points right, +positive Y points up and negative Z points forward. + +The simplest and least flexible way to play a sound is like so: + + ```c + ma_engine_play_sound(&engine, "my_sound.wav", pGroup); + ``` + +This is a "fire and forget" style of function. The engine will manage the `ma_sound` object +internally. When the sound finishes playing, it'll be put up for recycling. For more flexibility +you'll want to initialize a sound object: + + ```c + ma_sound sound; + + result = ma_sound_init_from_file(&engine, "my_sound.wav", flags, pGroup, NULL, &sound); + if (result != MA_SUCCESS) { + return result; // Failed to load sound. + } + ``` + +Sounds need to be uninitialized with `ma_sound_uninit()`. + +The example above loads a sound from a file. If the resource manager has been disabled you will not +be able to use this function and instead you'll need to initialize a sound directly from a data +source: + + ```c + ma_sound sound; + + result = ma_sound_init_from_data_source(&engine, &dataSource, flags, pGroup, &sound); + if (result != MA_SUCCESS) { + return result; + } + ``` + +Each `ma_sound` object represents a single instance of the sound. If you want to play the same +sound multiple times at the same time, you need to initialize a separate `ma_sound` object. + +For the most flexibility when initializing sounds, use `ma_sound_init_ex()`. This uses miniaudio's +standard config/init pattern: + + ```c + ma_sound sound; + ma_sound_config soundConfig; + + soundConfig = ma_sound_config_init(); + soundConfig.pFilePath = NULL; // Set this to load from a file path. + soundConfig.pDataSource = NULL; // Set this to initialize from an existing data source. + soundConfig.pInitialAttachment = &someNodeInTheNodeGraph; + soundConfig.initialAttachmentInputBusIndex = 0; + soundConfig.channelsIn = 1; + soundConfig.channelsOut = 0; // Set to 0 to use the engine's native channel count. + + result = ma_sound_init_ex(&soundConfig, &sound); + if (result != MA_SUCCESS) { + return result; + } + ``` + +In the example above, the sound is being initialized without a file nor a data source. This is +valid, in which case the sound acts as a node in the middle of the node graph. This means you can +connect other sounds to this sound and allow it to act like a sound group. Indeed, this is exactly +what a `ma_sound_group` is. + +When loading a sound, you specify a set of flags that control how the sound is loaded and what +features are enabled for that sound. When no flags are set, the sound will be fully loaded into +memory in exactly the same format as how it's stored on the file system. The resource manager will +allocate a block of memory and then load the file directly into it. When reading audio data, it +will be decoded dynamically on the fly. In order to save processing time on the audio thread, it +might be beneficial to pre-decode the sound. You can do this with the `MA_SOUND_FLAG_DECODE` flag: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE, pGroup, NULL, &sound); + ``` + +By default, sounds will be loaded synchronously, meaning `ma_sound_init_*()` will not return until +the sound has been fully loaded. If this is prohibitive you can instead load sounds asynchronously +by specifying the `MA_SOUND_FLAG_ASYNC` flag: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, NULL, &sound); + ``` + +This will result in `ma_sound_init_*()` returning quickly, but the sound won't yet have been fully +loaded. When you start the sound, it won't output anything until some sound is available. The sound +will start outputting audio before the sound has been fully decoded when the `MA_SOUND_FLAG_DECODE` +is specified. + +If you need to wait for an asynchronously loaded sound to be fully loaded, you can use a fence. A +fence in miniaudio is a simple synchronization mechanism which simply blocks until it's internal +counter hit's zero. You can specify a fence like so: + + ```c + ma_result result; + ma_fence fence; + ma_sound sounds[4]; + + result = ma_fence_init(&fence); + if (result != MA_SUCCESS) { + return result; + } + + // Load some sounds asynchronously. + for (int iSound = 0; iSound < 4; iSound += 1) { + ma_sound_init_from_file(&engine, mySoundFilesPaths[iSound], MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, &fence, &sounds[iSound]); + } + + // ... do some other stuff here in the mean time ... + + // Wait for all sounds to finish loading. + ma_fence_wait(&fence); + ``` + +If loading the entire sound into memory is prohibitive, you can also configure the engine to stream +the audio data: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_STREAM, pGroup, NULL, &sound); + ``` + +When streaming sounds, 2 seconds worth of audio data is stored in memory. Although it should work +fine, it's inefficient to use streaming for short sounds. Streaming is useful for things like music +tracks in games. + +When loading a sound from a file path, the engine will reference count the file to prevent it from +being loaded if it's already in memory. When you uninitialize a sound, the reference count will be +decremented, and if it hits zero, the sound will be unloaded from memory. This reference counting +system is not used for streams. The engine will use a 64-bit hash of the file name when comparing +file paths which means there's a small chance you might encounter a name collision. If this is an +issue, you'll need to use a different name for one of the colliding file paths, or just not load +from files and instead load from a data source. + +You can use `ma_sound_init_copy()` to initialize a copy of another sound. Note, however, that this +only works for sounds that were initialized with `ma_sound_init_from_file()` and without the +`MA_SOUND_FLAG_STREAM` flag. + +When you initialize a sound, if you specify a sound group the sound will be attached to that group +automatically. If you set it to NULL, it will be automatically attached to the engine's endpoint. +If you would instead rather leave the sound unattached by default, you can specify the +`MA_SOUND_FLAG_NO_DEFAULT_ATTACHMENT` flag. This is useful if you want to set up a complex node +graph. + +Sounds are not started by default. To start a sound, use `ma_sound_start()`. Stop a sound with +`ma_sound_stop()`. + +Sounds can have their volume controlled with `ma_sound_set_volume()` in the same way as the +engine's master volume. + +Sounds support stereo panning and pitching. Set the pan with `ma_sound_set_pan()`. Setting the pan +to 0 will result in an unpanned sound. Setting it to -1 will shift everything to the left, whereas ++1 will shift it to the right. The pitch can be controlled with `ma_sound_set_pitch()`. A larger +value will result in a higher pitch. The pitch must be greater than 0. + +The engine supports 3D spatialization of sounds. By default sounds will have spatialization +enabled, but if a sound does not need to be spatialized it's best to disable it. There are two ways +to disable spatialization of a sound: + + ```c + // Disable spatialization at initialization time via a flag: + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_NO_SPATIALIZATION, NULL, NULL, &sound); + + // Dynamically disable or enable spatialization post-initialization: + ma_sound_set_spatialization_enabled(&sound, isSpatializationEnabled); + ``` + +By default sounds will be spatialized based on the closest listener. If a sound should always be +spatialized relative to a specific listener it can be pinned to one: + + ```c + ma_sound_set_pinned_listener_index(&sound, listenerIndex); + ``` + +Like listeners, sounds have a position. By default, the position of a sound is in absolute space, +but it can be changed to be relative to a listener: + + ```c + ma_sound_set_positioning(&sound, ma_positioning_relative); + ``` + +Note that relative positioning of a sound only makes sense if there is either only one listener, or +the sound is pinned to a specific listener. To set the position of a sound: + + ```c + ma_sound_set_position(&sound, posX, posY, posZ); + ``` + +The direction works the same way as a listener and represents the sound's forward direction: + + ```c + ma_sound_set_direction(&sound, forwardX, forwardY, forwardZ); + ``` + +Sound's also have a cone for controlling directional attenuation. This works exactly the same as +listeners: + + ```c + ma_sound_set_cone(&sound, innerAngleInRadians, outerAngleInRadians, outerGain); + ``` + +The velocity of a sound is used for doppler effect and can be set as such: + + ```c + ma_sound_set_velocity(&sound, velocityX, velocityY, velocityZ); + ``` + +The engine supports different attenuation models which can be configured on a per-sound basis. By +default the attenuation model is set to `ma_attenuation_model_inverse` which is the equivalent to +OpenAL's `AL_INVERSE_DISTANCE_CLAMPED`. Configure the attenuation model like so: + + ```c + ma_sound_set_attenuation_model(&sound, ma_attenuation_model_inverse); + ``` + +The supported attenuation models include the following: + + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_none | No distance attenuation. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_inverse | Equivalent to `AL_INVERSE_DISTANCE_CLAMPED`. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_linear | Linear attenuation. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_exponential | Exponential attenuation. | + +----------------------------------+----------------------------------------------+ + +To control how quickly a sound rolls off as it moves away from the listener, you need to configure +the rolloff: + + ```c + ma_sound_set_rolloff(&sound, rolloff); + ``` + +You can control the minimum and maximum gain to apply from spatialization: + + ```c + ma_sound_set_min_gain(&sound, minGain); + ma_sound_set_max_gain(&sound, maxGain); + ``` + +Likewise, in the calculation of attenuation, you can control the minimum and maximum distances for +the attenuation calculation. This is useful if you want to ensure sounds don't drop below a certain +volume after the listener moves further away and to have sounds play a maximum volume when the +listener is within a certain distance: + + ```c + ma_sound_set_min_distance(&sound, minDistance); + ma_sound_set_max_distance(&sound, maxDistance); + ``` + +The engine's spatialization system supports doppler effect. The doppler factor can be configure on +a per-sound basis like so: + + ```c + ma_sound_set_doppler_factor(&sound, dopplerFactor); + ``` + +You can fade sounds in and out with `ma_sound_set_fade_in_pcm_frames()` and +`ma_sound_set_fade_in_milliseconds()`. Set the volume to -1 to use the current volume as the +starting volume: + + ```c + // Fade in over 1 second. + ma_sound_set_fade_in_milliseconds(&sound, 0, 1, 1000); + + // ... sometime later ... + + // Fade out over 1 second, starting from the current volume. + ma_sound_set_fade_in_milliseconds(&sound, -1, 0, 1000); + ``` + +By default sounds will start immediately, but sometimes for timing and synchronization purposes it +can be useful to schedule a sound to start or stop: + + ```c + // Start the sound in 1 second from now. + ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 1)); + + // Stop the sound in 2 seconds from now. + ma_sound_set_stop_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2)); + ``` + +Note that scheduling a start time still requires an explicit call to `ma_sound_start()` before +anything will play. + +The time is specified in global time which is controlled by the engine. You can get the engine's +current time with `ma_engine_get_time_in_pcm_frames()`. The engine's global time is incremented +automatically as audio data is read, but it can be reset with `ma_engine_set_time_in_pcm_frames()` +in case it needs to be resynchronized for some reason. + +To determine whether or not a sound is currently playing, use `ma_sound_is_playing()`. This will +take the scheduled start and stop times into account. + +Whether or not a sound should loop can be controlled with `ma_sound_set_looping()`. Sounds will not +be looping by default. Use `ma_sound_is_looping()` to determine whether or not a sound is looping. + +Use `ma_sound_at_end()` to determine whether or not a sound is currently at the end. For a looping +sound this should never return true. Alternatively, you can configure a callback that will be fired +when the sound reaches the end. Note that the callback is fired from the audio thread which means +you cannot be uninitializing sound from the callback. To set the callback you can use +`ma_sound_set_end_callback()`. Alternatively, if you're using `ma_sound_init_ex()`, you can pass it +into the config like so: + + ```c + soundConfig.endCallback = my_end_callback; + soundConfig.pEndCallbackUserData = pMyEndCallbackUserData; + ``` + +The end callback is declared like so: + + ```c + void my_end_callback(void* pUserData, ma_sound* pSound) + { + ... + } + ``` + +Internally a sound wraps around a data source. Some APIs exist to control the underlying data +source, mainly for convenience: + + ```c + ma_sound_seek_to_pcm_frame(&sound, frameIndex); + ma_sound_get_data_format(&sound, &format, &channels, &sampleRate, pChannelMap, channelMapCapacity); + ma_sound_get_cursor_in_pcm_frames(&sound, &cursor); + ma_sound_get_length_in_pcm_frames(&sound, &length); + ``` + +Sound groups have the same API as sounds, only they are called `ma_sound_group`, and since they do +not have any notion of a data source, anything relating to a data source is unavailable. + +Internally, sound data is loaded via the `ma_decoder` API which means by default it only supports +file formats that have built-in support in miniaudio. You can extend this to support any kind of +file format through the use of custom decoders. To do this you'll need to use a self-managed +resource manager and configure it appropriately. See the "Resource Management" section below for +details on how to set this up. + + +6. Resource Management +====================== +Many programs will want to manage sound resources for things such as reference counting and +streaming. This is supported by miniaudio via the `ma_resource_manager` API. + +The resource manager is mainly responsible for the following: + + * Loading of sound files into memory with reference counting. + * Streaming of sound data. + +When loading a sound file, the resource manager will give you back a `ma_data_source` compatible +object called `ma_resource_manager_data_source`. This object can be passed into any +`ma_data_source` API which is how you can read and seek audio data. When loading a sound file, you +specify whether or not you want the sound to be fully loaded into memory (and optionally +pre-decoded) or streamed. When loading into memory, you can also specify whether or not you want +the data to be loaded asynchronously. + +The example below is how you can initialize a resource manager using it's default configuration: + + ```c + ma_resource_manager_config config; + ma_resource_manager resourceManager; + + config = ma_resource_manager_config_init(); + result = ma_resource_manager_init(&config, &resourceManager); + if (result != MA_SUCCESS) { + ma_device_uninit(&device); + printf("Failed to initialize the resource manager."); + return -1; + } + ``` + +You can configure the format, channels and sample rate of the decoded audio data. By default it +will use the file's native data format, but you can configure it to use a consistent format. This +is useful for offloading the cost of data conversion to load time rather than dynamically +converting at mixing time. To do this, you configure the decoded format, channels and sample rate +like the code below: + + ```c + config = ma_resource_manager_config_init(); + config.decodedFormat = device.playback.format; + config.decodedChannels = device.playback.channels; + config.decodedSampleRate = device.sampleRate; + ``` + +In the code above, the resource manager will be configured so that any decoded audio data will be +pre-converted at load time to the device's native data format. If instead you used defaults and +the data format of the file did not match the device's data format, you would need to convert the +data at mixing time which may be prohibitive in high-performance and large scale scenarios like +games. + +Internally the resource manager uses the `ma_decoder` API to load sounds. This means by default it +only supports decoders that are built into miniaudio. It's possible to support additional encoding +formats through the use of custom decoders. To do so, pass in your `ma_decoding_backend_vtable` +vtables into the resource manager config: + + ```c + ma_decoding_backend_vtable* pCustomBackendVTables[] = + { + &g_ma_decoding_backend_vtable_libvorbis, + &g_ma_decoding_backend_vtable_libopus + }; + + ... + + resourceManagerConfig.ppCustomDecodingBackendVTables = pCustomBackendVTables; + resourceManagerConfig.customDecodingBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); + resourceManagerConfig.pCustomDecodingBackendUserData = NULL; + ``` + +This system can allow you to support any kind of file format. See the "Decoding" section for +details on how to implement custom decoders. The miniaudio repository includes examples for Opus +via libopus and libopusfile and Vorbis via libvorbis and libvorbisfile. + +Asynchronicity is achieved via a job system. When an operation needs to be performed, such as the +decoding of a page, a job will be posted to a queue which will then be processed by a job thread. +By default there will be only one job thread running, but this can be configured, like so: + + ```c + config = ma_resource_manager_config_init(); + config.jobThreadCount = MY_JOB_THREAD_COUNT; + ``` + +By default job threads are managed internally by the resource manager, however you can also self +manage your job threads if, for example, you want to integrate the job processing into your +existing job infrastructure, or if you simply don't like the way the resource manager does it. To +do this, just set the job thread count to 0 and process jobs manually. To process jobs, you first +need to retrieve a job using `ma_resource_manager_next_job()` and then process it using +`ma_job_process()`: + + ```c + config = ma_resource_manager_config_init(); + config.jobThreadCount = 0; // Don't manage any job threads internally. + config.flags = MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING; // Optional. Makes `ma_resource_manager_next_job()` non-blocking. + + // ... Initialize your custom job threads ... + + void my_custom_job_thread(...) + { + for (;;) { + ma_job job; + ma_result result = ma_resource_manager_next_job(pMyResourceManager, &job); + if (result != MA_SUCCESS) { + if (result == MA_NO_DATA_AVAILABLE) { + // No jobs are available. Keep going. Will only get this if the resource manager was initialized + // with MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING. + continue; + } else if (result == MA_CANCELLED) { + // MA_JOB_TYPE_QUIT was posted. Exit. + break; + } else { + // Some other error occurred. + break; + } + } + + ma_job_process(&job); + } + } + ``` + +In the example above, the `MA_JOB_TYPE_QUIT` event is the used as the termination +indicator, but you can use whatever you would like to terminate the thread. The call to +`ma_resource_manager_next_job()` is blocking by default, but can be configured to be non-blocking +by initializing the resource manager with the `MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING` configuration +flag. Note that the `MA_JOB_TYPE_QUIT` will never be removed from the job queue. This +is to give every thread the opportunity to catch the event and terminate naturally. + +When loading a file, it's sometimes convenient to be able to customize how files are opened and +read instead of using standard `fopen()`, `fclose()`, etc. which is what miniaudio will use by +default. This can be done by setting `pVFS` member of the resource manager's config: + + ```c + // Initialize your custom VFS object. See documentation for VFS for information on how to do this. + my_custom_vfs vfs = my_custom_vfs_init(); + + config = ma_resource_manager_config_init(); + config.pVFS = &vfs; + ``` + +This is particularly useful in programs like games where you want to read straight from an archive +rather than the normal file system. If you do not specify a custom VFS, the resource manager will +use the operating system's normal file operations. + +To load a sound file and create a data source, call `ma_resource_manager_data_source_init()`. When +loading a sound you need to specify the file path and options for how the sounds should be loaded. +By default a sound will be loaded synchronously. The returned data source is owned by the caller +which means the caller is responsible for the allocation and freeing of the data source. Below is +an example for initializing a data source: + + ```c + ma_resource_manager_data_source dataSource; + ma_result result = ma_resource_manager_data_source_init(pResourceManager, pFilePath, flags, &dataSource); + if (result != MA_SUCCESS) { + // Error. + } + + // ... + + // A ma_resource_manager_data_source object is compatible with the `ma_data_source` API. To read data, just call + // the `ma_data_source_read_pcm_frames()` like you would with any normal data source. + result = ma_data_source_read_pcm_frames(&dataSource, pDecodedData, frameCount, &framesRead); + if (result != MA_SUCCESS) { + // Failed to read PCM frames. + } + + // ... + + ma_resource_manager_data_source_uninit(&dataSource); + ``` + +The `flags` parameter specifies how you want to perform loading of the sound file. It can be a +combination of the following flags: + + ``` + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_LOOPING + ``` + +When no flags are specified (set to 0), the sound will be fully loaded into memory, but not +decoded, meaning the raw file data will be stored in memory, and then dynamically decoded when +`ma_data_source_read_pcm_frames()` is called. To instead decode the audio data before storing it in +memory, use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` flag. By default, the sound file will +be loaded synchronously, meaning `ma_resource_manager_data_source_init()` will only return after +the entire file has been loaded. This is good for simplicity, but can be prohibitively slow. You +can instead load the sound asynchronously using the `MA_RESOURCE_MANAGER_DATA_SOURCE_ASYNC` flag. +This will result in `ma_resource_manager_data_source_init()` returning quickly, but no data will be +returned by `ma_data_source_read_pcm_frames()` until some data is available. When no data is +available because the asynchronous decoding hasn't caught up, `MA_BUSY` will be returned by +`ma_data_source_read_pcm_frames()`. + +For large sounds, it's often prohibitive to store the entire file in memory. To mitigate this, you +can instead stream audio data which you can do by specifying the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. When streaming, data will be decoded in 1 +second pages. When a new page needs to be decoded, a job will be posted to the job queue and then +subsequently processed in a job thread. + +The `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_LOOPING` flag can be used so that the sound will loop +when it reaches the end by default. It's recommended you use this flag when you want to have a +looping streaming sound. If you try loading a very short sound as a stream, you will get a glitch. +This is because the resource manager needs to pre-fill the initial buffer at initialization time, +and if you don't specify the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_LOOPING` flag, the resource +manager will assume the sound is not looping and will stop filling the buffer when it reaches the +end, therefore resulting in a discontinuous buffer. + +For in-memory sounds, reference counting is used to ensure the data is loaded only once. This means +multiple calls to `ma_resource_manager_data_source_init()` with the same file path will result in +the file data only being loaded once. Each call to `ma_resource_manager_data_source_init()` must be +matched up with a call to `ma_resource_manager_data_source_uninit()`. Sometimes it can be useful +for a program to register self-managed raw audio data and associate it with a file path. Use the +`ma_resource_manager_register_*()` and `ma_resource_manager_unregister_*()` APIs to do this. +`ma_resource_manager_register_decoded_data()` is used to associate a pointer to raw, self-managed +decoded audio data in the specified data format with the specified name. Likewise, +`ma_resource_manager_register_encoded_data()` is used to associate a pointer to raw self-managed +encoded audio data (the raw file data) with the specified name. Note that these names need not be +actual file paths. When `ma_resource_manager_data_source_init()` is called (without the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag), the resource manager will look for these +explicitly registered data buffers and, if found, will use it as the backing data for the data +source. Note that the resource manager does *not* make a copy of this data so it is up to the +caller to ensure the pointer stays valid for its lifetime. Use +`ma_resource_manager_unregister_data()` to unregister the self-managed data. You can also use +`ma_resource_manager_register_file()` and `ma_resource_manager_unregister_file()` to register and +unregister a file. It does not make sense to use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` +flag with a self-managed data pointer. + + +6.1. Asynchronous Loading and Synchronization +--------------------------------------------- +When loading asynchronously, it can be useful to poll whether or not loading has finished. Use +`ma_resource_manager_data_source_result()` to determine this. For in-memory sounds, this will +return `MA_SUCCESS` when the file has been *entirely* decoded. If the sound is still being decoded, +`MA_BUSY` will be returned. Otherwise, some other error code will be returned if the sound failed +to load. For streaming data sources, `MA_SUCCESS` will be returned when the first page has been +decoded and the sound is ready to be played. If the first page is still being decoded, `MA_BUSY` +will be returned. Otherwise, some other error code will be returned if the sound failed to load. + +In addition to polling, you can also use a simple synchronization object called a "fence" to wait +for asynchronously loaded sounds to finish. This is called `ma_fence`. The advantage to using a +fence is that it can be used to wait for a group of sounds to finish loading rather than waiting +for sounds on an individual basis. There are two stages to loading a sound: + + * Initialization of the internal decoder; and + * Completion of decoding of the file (the file is fully decoded) + +You can specify separate fences for each of the different stages. Waiting for the initialization +of the internal decoder is important for when you need to know the sample format, channels and +sample rate of the file. + +The example below shows how you could use a fence when loading a number of sounds: + + ```c + // This fence will be released when all sounds are finished loading entirely. + ma_fence fence; + ma_fence_init(&fence); + + // This will be passed into the initialization routine for each sound. + ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); + notifications.done.pFence = &fence; + + // Now load a bunch of sounds: + for (iSound = 0; iSound < soundCount; iSound += 1) { + ma_resource_manager_data_source_init(pResourceManager, pSoundFilePaths[iSound], flags, ¬ifications, &pSoundSources[iSound]); + } + + // ... DO SOMETHING ELSE WHILE SOUNDS ARE LOADING ... + + // Wait for loading of sounds to finish. + ma_fence_wait(&fence); + ``` + +In the example above we used a fence for waiting until the entire file has been fully decoded. If +you only need to wait for the initialization of the internal decoder to complete, you can use the +`init` member of the `ma_resource_manager_pipeline_notifications` object: + + ```c + notifications.init.pFence = &fence; + ``` + +If a fence is not appropriate for your situation, you can instead use a callback that is fired on +an individual sound basis. This is done in a very similar way to fences: + + ```c + typedef struct + { + ma_async_notification_callbacks cb; + void* pMyData; + } my_notification; + + void my_notification_callback(ma_async_notification* pNotification) + { + my_notification* pMyNotification = (my_notification*)pNotification; + + // Do something in response to the sound finishing loading. + } + + ... + + my_notification myCallback; + myCallback.cb.onSignal = my_notification_callback; + myCallback.pMyData = pMyData; + + ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); + notifications.done.pNotification = &myCallback; + + ma_resource_manager_data_source_init(pResourceManager, "my_sound.wav", flags, ¬ifications, &mySound); + ``` + +In the example above we just extend the `ma_async_notification_callbacks` object and pass an +instantiation into the `ma_resource_manager_pipeline_notifications` in the same way as we did with +the fence, only we set `pNotification` instead of `pFence`. You can set both of these at the same +time and they should both work as expected. If using the `pNotification` system, you need to ensure +your `ma_async_notification_callbacks` object stays valid. + + + +6.2. Resource Manager Implementation Details +-------------------------------------------- +Resources are managed in two main ways: + + * By storing the entire sound inside an in-memory buffer (referred to as a data buffer) + * By streaming audio data on the fly (referred to as a data stream) + +A resource managed data source (`ma_resource_manager_data_source`) encapsulates a data buffer or +data stream, depending on whether or not the data source was initialized with the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. If so, it will make use of a +`ma_resource_manager_data_stream` object. Otherwise it will use a `ma_resource_manager_data_buffer` +object. Both of these objects are data sources which means they can be used with any +`ma_data_source_*()` API. + +Another major feature of the resource manager is the ability to asynchronously decode audio files. +This relieves the audio thread of time-consuming decoding which can negatively affect scalability +due to the audio thread needing to complete it's work extremely quickly to avoid glitching. +Asynchronous decoding is achieved through a job system. There is a central multi-producer, +multi-consumer, fixed-capacity job queue. When some asynchronous work needs to be done, a job is +posted to the queue which is then read by a job thread. The number of job threads can be +configured for improved scalability, and job threads can all run in parallel without needing to +worry about the order of execution (how this is achieved is explained below). + +When a sound is being loaded asynchronously, playback can begin before the sound has been fully +decoded. This enables the application to start playback of the sound quickly, while at the same +time allowing to resource manager to keep loading in the background. Since there may be less +threads than the number of sounds being loaded at a given time, a simple scheduling system is used +to keep decoding time balanced and fair. The resource manager solves this by splitting decoding +into chunks called pages. By default, each page is 1 second long. When a page has been decoded, a +new job will be posted to start decoding the next page. By dividing up decoding into pages, an +individual sound shouldn't ever delay every other sound from having their first page decoded. Of +course, when loading many sounds at the same time, there will always be an amount of time required +to process jobs in the queue so in heavy load situations there will still be some delay. To +determine if a data source is ready to have some frames read, use +`ma_resource_manager_data_source_get_available_frames()`. This will return the number of frames +available starting from the current position. + + +6.2.1. Job Queue +---------------- +The resource manager uses a job queue which is multi-producer, multi-consumer, and fixed-capacity. +This job queue is not currently lock-free, and instead uses a spinlock to achieve thread-safety. +Only a fixed number of jobs can be allocated and inserted into the queue which is done through a +lock-free data structure for allocating an index into a fixed sized array, with reference counting +for mitigation of the ABA problem. The reference count is 32-bit. + +For many types of jobs it's important that they execute in a specific order. In these cases, jobs +are executed serially. For the resource manager, serial execution of jobs is only required on a +per-object basis (per data buffer or per data stream). Each of these objects stores an execution +counter. When a job is posted it is associated with an execution counter. When the job is +processed, it checks if the execution counter of the job equals the execution counter of the +owning object and if so, processes the job. If the counters are not equal, the job will be posted +back onto the job queue for later processing. When the job finishes processing the execution order +of the main object is incremented. This system means the no matter how many job threads are +executing, decoding of an individual sound will always get processed serially. The advantage to +having multiple threads comes into play when loading multiple sounds at the same time. + +The resource manager's job queue is not 100% lock-free and will use a spinlock to achieve +thread-safety for a very small section of code. This is only relevant when the resource manager +uses more than one job thread. If only using a single job thread, which is the default, the +lock should never actually wait in practice. The amount of time spent locking should be quite +short, but it's something to be aware of for those who have pedantic lock-free requirements and +need to use more than one job thread. There are plans to remove this lock in a future version. + +In addition, posting a job will release a semaphore, which on Win32 is implemented with +`ReleaseSemaphore` and on POSIX platforms via a condition variable: + + ```c + pthread_mutex_lock(&pSemaphore->lock); + { + pSemaphore->value += 1; + pthread_cond_signal(&pSemaphore->cond); + } + pthread_mutex_unlock(&pSemaphore->lock); + ``` + +Again, this is relevant for those with strict lock-free requirements in the audio thread. To avoid +this, you can use non-blocking mode (via the `MA_JOB_QUEUE_FLAG_NON_BLOCKING` +flag) and implement your own job processing routine (see the "Resource Manager" section above for +details on how to do this). + + + +6.2.2. Data Buffers +------------------- +When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag is excluded at initialization time, the +resource manager will try to load the data into an in-memory data buffer. Before doing so, however, +it will first check if the specified file is already loaded. If so, it will increment a reference +counter and just use the already loaded data. This saves both time and memory. When the data buffer +is uninitialized, the reference counter will be decremented. If the counter hits zero, the file +will be unloaded. This is a detail to keep in mind because it could result in excessive loading and +unloading of a sound. For example, the following sequence will result in a file be loaded twice, +once after the other: + + ```c + ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer0); // Refcount = 1. Initial load. + ma_resource_manager_data_source_uninit(&myDataBuffer0); // Refcount = 0. Unloaded. + + ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer1); // Refcount = 1. Reloaded because previous uninit() unloaded it. + ma_resource_manager_data_source_uninit(&myDataBuffer1); // Refcount = 0. Unloaded. + ``` + +A binary search tree (BST) is used for storing data buffers as it has good balance between +efficiency and simplicity. The key of the BST is a 64-bit hash of the file path that was passed +into `ma_resource_manager_data_source_init()`. The advantage of using a hash is that it saves +memory over storing the entire path, has faster comparisons, and results in a mostly balanced BST +due to the random nature of the hash. The disadvantages are that file names are case-sensitive and +there's a small chance of name collisions. If case-sensitivity is an issue, you should normalize +your file names to upper- or lower-case before initializing your data sources. If name collisions +become an issue, you'll need to change the name of one of the colliding names or just not use the +resource manager. + +When a sound file has not already been loaded and the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` +flag is excluded, the file will be decoded synchronously by the calling thread. There are two +options for controlling how the audio is stored in the data buffer - encoded or decoded. When the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` option is excluded, the raw file data will be stored +in memory. Otherwise the sound will be decoded before storing it in memory. Synchronous loading is +a very simple and standard process of simply adding an item to the BST, allocating a block of +memory and then decoding (if `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` is specified). + +When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag is specified, loading of the data buffer +is done asynchronously. In this case, a job is posted to the queue to start loading and then the +function immediately returns, setting an internal result code to `MA_BUSY`. This result code is +returned when the program calls `ma_resource_manager_data_source_result()`. When decoding has fully +completed `MA_SUCCESS` will be returned. This can be used to know if loading has fully completed. + +When loading asynchronously, a single job is posted to the queue of the type +`MA_JOB_TYPE_RESOURCE_MANAGER_LOAD_DATA_BUFFER_NODE`. This involves making a copy of the file path and +associating it with job. When the job is processed by the job thread, it will first load the file +using the VFS associated with the resource manager. When using a custom VFS, it's important that it +be completely thread-safe because it will be used from one or more job threads at the same time. +Individual files should only ever be accessed by one thread at a time, however. After opening the +file via the VFS, the job will determine whether or not the file is being decoded. If not, it +simply allocates a block of memory and loads the raw file contents into it and returns. On the +other hand, when the file is being decoded, it will first allocate a decoder on the heap and +initialize it. Then it will check if the length of the file is known. If so it will allocate a +block of memory to store the decoded output and initialize it to silence. If the size is unknown, +it will allocate room for one page. After memory has been allocated, the first page will be +decoded. If the sound is shorter than a page, the result code will be set to `MA_SUCCESS` and the +completion event will be signalled and loading is now complete. If, however, there is more to +decode, a job with the code `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` is posted. This job +will decode the next page and perform the same process if it reaches the end. If there is more to +decode, the job will post another `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` job which will +keep on happening until the sound has been fully decoded. For sounds of an unknown length, each +page will be linked together as a linked list. Internally this is implemented via the +`ma_paged_audio_buffer` object. + + +6.2.3. Data Streams +------------------- +Data streams only ever store two pages worth of data for each instance. They are most useful for +large sounds like music tracks in games that would consume too much memory if fully decoded in +memory. After every frame from a page has been read, a job will be posted to load the next page +which is done from the VFS. + +For data streams, the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag will determine whether or +not initialization of the data source waits until the two pages have been decoded. When unset, +`ma_resource_manager_data_source_init()` will wait until the two pages have been loaded, otherwise +it will return immediately. + +When frames are read from a data stream using `ma_resource_manager_data_source_read_pcm_frames()`, +`MA_BUSY` will be returned if there are no frames available. If there are some frames available, +but less than the number requested, `MA_SUCCESS` will be returned, but the actual number of frames +read will be less than the number requested. Due to the asynchronous nature of data streams, +seeking is also asynchronous. If the data stream is in the middle of a seek, `MA_BUSY` will be +returned when trying to read frames. + +When `ma_resource_manager_data_source_read_pcm_frames()` results in a page getting fully consumed +a job is posted to load the next page. This will be posted from the same thread that called +`ma_resource_manager_data_source_read_pcm_frames()`. + +Data streams are uninitialized by posting a job to the queue, but the function won't return until +that job has been processed. The reason for this is that the caller owns the data stream object and +therefore miniaudio needs to ensure everything completes before handing back control to the caller. +Also, if the data stream is uninitialized while pages are in the middle of decoding, they must +complete before destroying any underlying object and the job system handles this cleanly. + +Note that when a new page needs to be loaded, a job will be posted to the resource manager's job +thread from the audio thread. You must keep in mind the details mentioned in the "Job Queue" +section above regarding locking when posting an event if you require a strictly lock-free audio +thread. + + + +7. Node Graph +============= +miniaudio's routing infrastructure follows a node graph paradigm. The idea is that you create a +node whose outputs are attached to inputs of another node, thereby creating a graph. There are +different types of nodes, with each node in the graph processing input data to produce output, +which is then fed through the chain. Each node in the graph can apply their own custom effects. At +the start of the graph will usually be one or more data source nodes which have no inputs and +instead pull their data from a data source. At the end of the graph is an endpoint which represents +the end of the chain and is where the final output is ultimately extracted from. + +Each node has a number of input buses and a number of output buses. An output bus from a node is +attached to an input bus of another. Multiple nodes can connect their output buses to another +node's input bus, in which case their outputs will be mixed before processing by the node. Below is +a diagram that illustrates a hypothetical node graph setup: + + ``` + >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Data flows left to right >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> + + +---------------+ +-----------------+ + | Data Source 1 =----+ +----------+ +----= Low Pass Filter =----+ + +---------------+ | | =----+ +-----------------+ | +----------+ + +----= Splitter | +----= ENDPOINT | + +---------------+ | | =----+ +-----------------+ | +----------+ + | Data Source 2 =----+ +----------+ +----= Echo / Delay =----+ + +---------------+ +-----------------+ + ``` + +In the above graph, it starts with two data sources whose outputs are attached to the input of a +splitter node. It's at this point that the two data sources are mixed. After mixing, the splitter +performs it's processing routine and produces two outputs which is simply a duplication of the +input stream. One output is attached to a low pass filter, whereas the other output is attached to +a echo/delay. The outputs of the low pass filter and the echo are attached to the endpoint, and +since they're both connected to the same input bus, they'll be mixed. + +Each input bus must be configured to accept the same number of channels, but the number of channels +used by input buses can be different to the number of channels for output buses in which case +miniaudio will automatically convert the input data to the output channel count before processing. +The number of channels of an output bus of one node must match the channel count of the input bus +it's attached to. The channel counts cannot be changed after the node has been initialized. If you +attempt to attach an output bus to an input bus with a different channel count, attachment will +fail. + +To use a node graph, you first need to initialize a `ma_node_graph` object. This is essentially a +container around the entire graph. The `ma_node_graph` object is required for some thread-safety +issues which will be explained later. A `ma_node_graph` object is initialized using miniaudio's +standard config/init system: + + ```c + ma_node_graph_config nodeGraphConfig = ma_node_graph_config_init(myChannelCount); + + result = ma_node_graph_init(&nodeGraphConfig, NULL, &nodeGraph); // Second parameter is a pointer to allocation callbacks. + if (result != MA_SUCCESS) { + // Failed to initialize node graph. + } + ``` + +When you initialize the node graph, you're specifying the channel count of the endpoint. The +endpoint is a special node which has one input bus and one output bus, both of which have the +same channel count, which is specified in the config. Any nodes that connect directly to the +endpoint must be configured such that their output buses have the same channel count. When you read +audio data from the node graph, it'll have the channel count you specified in the config. To read +data from the graph: + + ```c + ma_uint32 framesRead; + result = ma_node_graph_read_pcm_frames(&nodeGraph, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + // Failed to read data from the node graph. + } + ``` + +When you read audio data, miniaudio starts at the node graph's endpoint node which then pulls in +data from its input attachments, which in turn recursively pull in data from their inputs, and so +on. At the start of the graph there will be some kind of data source node which will have zero +inputs and will instead read directly from a data source. The base nodes don't literally need to +read from a `ma_data_source` object, but they will always have some kind of underlying object that +sources some kind of audio. The `ma_data_source_node` node can be used to read from a +`ma_data_source`. Data is always in floating-point format and in the number of channels you +specified when the graph was initialized. The sample rate is defined by the underlying data sources. +It's up to you to ensure they use a consistent and appropriate sample rate. + +The `ma_node` API is designed to allow custom nodes to be implemented with relative ease, but +miniaudio includes a few stock nodes for common functionality. This is how you would initialize a +node which reads directly from a data source (`ma_data_source_node`) which is an example of one +of the stock nodes that comes with miniaudio: + + ```c + ma_data_source_node_config config = ma_data_source_node_config_init(pMyDataSource); + + ma_data_source_node dataSourceNode; + result = ma_data_source_node_init(&nodeGraph, &config, NULL, &dataSourceNode); + if (result != MA_SUCCESS) { + // Failed to create data source node. + } + ``` + +The data source node will use the output channel count to determine the channel count of the output +bus. There will be 1 output bus and 0 input buses (data will be drawn directly from the data +source). The data source must output to floating-point (`ma_format_f32`) or else an error will be +returned from `ma_data_source_node_init()`. + +By default the node will not be attached to the graph. To do so, use `ma_node_attach_output_bus()`: + + ```c + result = ma_node_attach_output_bus(&dataSourceNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); + if (result != MA_SUCCESS) { + // Failed to attach node. + } + ``` + +The code above connects the data source node directly to the endpoint. Since the data source node +has only a single output bus, the index will always be 0. Likewise, the endpoint only has a single +input bus which means the input bus index will also always be 0. + +To detach a specific output bus, use `ma_node_detach_output_bus()`. To detach all output buses, use +`ma_node_detach_all_output_buses()`. If you want to just move the output bus from one attachment to +another, you do not need to detach first. You can just call `ma_node_attach_output_bus()` and it'll +deal with it for you. + +Less frequently you may want to create a specialized node. This will be a node where you implement +your own processing callback to apply a custom effect of some kind. This is similar to initializing +one of the stock node types, only this time you need to specify a pointer to a vtable containing a +pointer to the processing function and the number of input and output buses. Example: + + ```c + static void my_custom_node_process_pcm_frames(ma_node* pNode, const float** ppFramesIn, ma_uint32* pFrameCountIn, float** ppFramesOut, ma_uint32* pFrameCountOut) + { + // Do some processing of ppFramesIn (one stream of audio data per input bus) + const float* pFramesIn_0 = ppFramesIn[0]; // Input bus @ index 0. + const float* pFramesIn_1 = ppFramesIn[1]; // Input bus @ index 1. + float* pFramesOut_0 = ppFramesOut[0]; // Output bus @ index 0. + + // Do some processing. On input, `pFrameCountIn` will be the number of input frames in each + // buffer in `ppFramesIn` and `pFrameCountOut` will be the capacity of each of the buffers + // in `ppFramesOut`. On output, `pFrameCountIn` should be set to the number of input frames + // your node consumed and `pFrameCountOut` should be set the number of output frames that + // were produced. + // + // You should process as many frames as you can. If your effect consumes input frames at the + // same rate as output frames (always the case, unless you're doing resampling), you need + // only look at `ppFramesOut` and process that exact number of frames. If you're doing + // resampling, you'll need to be sure to set both `pFrameCountIn` and `pFrameCountOut` + // properly. + } + + static ma_node_vtable my_custom_node_vtable = + { + my_custom_node_process_pcm_frames, // The function that will be called to process your custom node. This is where you'd implement your effect processing. + NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. + 2, // 2 input buses. + 1, // 1 output bus. + 0 // Default flags. + }; + + ... + + // Each bus needs to have a channel count specified. To do this you need to specify the channel + // counts in an array and then pass that into the node config. + ma_uint32 inputChannels[2]; // Equal in size to the number of input channels specified in the vtable. + ma_uint32 outputChannels[1]; // Equal in size to the number of output channels specified in the vtable. + + inputChannels[0] = channelsIn; + inputChannels[1] = channelsIn; + outputChannels[0] = channelsOut; + + ma_node_config nodeConfig = ma_node_config_init(); + nodeConfig.vtable = &my_custom_node_vtable; + nodeConfig.pInputChannels = inputChannels; + nodeConfig.pOutputChannels = outputChannels; + + ma_node_base node; + result = ma_node_init(&nodeGraph, &nodeConfig, NULL, &node); + if (result != MA_SUCCESS) { + // Failed to initialize node. + } + ``` + +When initializing a custom node, as in the code above, you'll normally just place your vtable in +static space. The number of input and output buses are specified as part of the vtable. If you need +a variable number of buses on a per-node bases, the vtable should have the relevant bus count set +to `MA_NODE_BUS_COUNT_UNKNOWN`. In this case, the bus count should be set in the node config: + + ```c + static ma_node_vtable my_custom_node_vtable = + { + my_custom_node_process_pcm_frames, // The function that will be called process your custom node. This is where you'd implement your effect processing. + NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. + MA_NODE_BUS_COUNT_UNKNOWN, // The number of input buses is determined on a per-node basis. + 1, // 1 output bus. + 0 // Default flags. + }; + + ... + + ma_node_config nodeConfig = ma_node_config_init(); + nodeConfig.vtable = &my_custom_node_vtable; + nodeConfig.inputBusCount = myBusCount; // <-- Since the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN, the input bus count should be set here. + nodeConfig.pInputChannels = inputChannels; // <-- Make sure there are nodeConfig.inputBusCount elements in this array. + nodeConfig.pOutputChannels = outputChannels; // <-- The vtable specifies 1 output bus, so there must be 1 element in this array. + ``` + +In the above example it's important to never set the `inputBusCount` and `outputBusCount` members +to anything other than their defaults if the vtable specifies an explicit count. They can only be +set if the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN in the relevant bus count. + +Most often you'll want to create a structure to encapsulate your node with some extra data. You +need to make sure the `ma_node_base` object is your first member of the structure: + + ```c + typedef struct + { + ma_node_base base; // <-- Make sure this is always the first member. + float someCustomData; + } my_custom_node; + ``` + +By doing this, your object will be compatible with all `ma_node` APIs and you can attach it to the +graph just like any other node. + +In the custom processing callback (`my_custom_node_process_pcm_frames()` in the example above), the +number of channels for each bus is what was specified by the config when the node was initialized +with `ma_node_init()`. In addition, all attachments to each of the input buses will have been +pre-mixed by miniaudio. The config allows you to specify different channel counts for each +individual input and output bus. It's up to the effect to handle it appropriate, and if it can't, +return an error in it's initialization routine. + +Custom nodes can be assigned some flags to describe their behaviour. These are set via the vtable +and include the following: + + +-----------------------------------------+---------------------------------------------------+ + | Flag Name | Description | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_PASSTHROUGH | Useful for nodes that do not do any kind of audio | + | | processing, but are instead used for tracking | + | | time, handling events, etc. Also used by the | + | | internal endpoint node. It reads directly from | + | | the input bus to the output bus. Nodes with this | + | | flag must have exactly 1 input bus and 1 output | + | | bus, and both buses must have the same channel | + | | counts. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_CONTINUOUS_PROCESSING | Causes the processing callback to be called even | + | | when no data is available to be read from input | + | | attachments. When a node has at least one input | + | | bus, but there are no inputs attached or the | + | | inputs do not deliver any data, the node's | + | | processing callback will not get fired. This flag | + | | will make it so the callback is always fired | + | | regardless of whether or not any input data is | + | | received. This is useful for effects like | + | | echos where there will be a tail of audio data | + | | that still needs to be processed even when the | + | | original data sources have reached their ends. It | + | | may also be useful for nodes that must always | + | | have their processing callback fired when there | + | | are no inputs attached. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_ALLOW_NULL_INPUT | Used in conjunction with | + | | `MA_NODE_FLAG_CONTINUOUS_PROCESSING`. When this | + | | is set, the `ppFramesIn` parameter of the | + | | processing callback will be set to NULL when | + | | there are no input frames are available. When | + | | this is unset, silence will be posted to the | + | | processing callback. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_DIFFERENT_PROCESSING_RATES | Used to tell miniaudio that input and output | + | | frames are processed at different rates. You | + | | should set this for any nodes that perform | + | | resampling. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_SILENT_OUTPUT | Used to tell miniaudio that a node produces only | + | | silent output. This is useful for nodes where you | + | | don't want the output to contribute to the final | + | | mix. An example might be if you want split your | + | | stream and have one branch be output to a file. | + | | When using this flag, you should avoid writing to | + | | the output buffer of the node's processing | + | | callback because miniaudio will ignore it anyway. | + +-----------------------------------------+---------------------------------------------------+ + + +If you need to make a copy of an audio stream for effect processing you can use a splitter node +called `ma_splitter_node`. This takes has 1 input bus and splits the stream into 2 output buses. +You can use it like this: + + ```c + ma_splitter_node_config splitterNodeConfig = ma_splitter_node_config_init(channels); + + ma_splitter_node splitterNode; + result = ma_splitter_node_init(&nodeGraph, &splitterNodeConfig, NULL, &splitterNode); + if (result != MA_SUCCESS) { + // Failed to create node. + } + + // Attach your output buses to two different input buses (can be on two different nodes). + ma_node_attach_output_bus(&splitterNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); // Attach directly to the endpoint. + ma_node_attach_output_bus(&splitterNode, 1, &myEffectNode, 0); // Attach to input bus 0 of some effect node. + ``` + +The volume of an output bus can be configured on a per-bus basis: + + ```c + ma_node_set_output_bus_volume(&splitterNode, 0, 0.5f); + ma_node_set_output_bus_volume(&splitterNode, 1, 0.5f); + ``` + +In the code above we're using the splitter node from before and changing the volume of each of the +copied streams. + +You can start and stop a node with the following: + + ```c + ma_node_set_state(&splitterNode, ma_node_state_started); // The default state. + ma_node_set_state(&splitterNode, ma_node_state_stopped); + ``` + +By default the node is in a started state, but since it won't be connected to anything won't +actually be invoked by the node graph until it's connected. When you stop a node, data will not be +read from any of its input connections. You can use this property to stop a group of sounds +atomically. + +You can configure the initial state of a node in it's config: + + ```c + nodeConfig.initialState = ma_node_state_stopped; + ``` + +Note that for the stock specialized nodes, all of their configs will have a `nodeConfig` member +which is the config to use with the base node. This is where the initial state can be configured +for specialized nodes: + + ```c + dataSourceNodeConfig.nodeConfig.initialState = ma_node_state_stopped; + ``` + +When using a specialized node like `ma_data_source_node` or `ma_splitter_node`, be sure to not +modify the `vtable` member of the `nodeConfig` object. + + +7.1. Timing +----------- +The node graph supports starting and stopping nodes at scheduled times. This is especially useful +for data source nodes where you want to get the node set up, but only start playback at a specific +time. There are two clocks: local and global. + +A local clock is per-node, whereas the global clock is per graph. Scheduling starts and stops can +only be done based on the global clock because the local clock will not be running while the node +is stopped. The global clocks advances whenever `ma_node_graph_read_pcm_frames()` is called. On the +other hand, the local clock only advances when the node's processing callback is fired, and is +advanced based on the output frame count. + +To retrieve the global time, use `ma_node_graph_get_time()`. The global time can be set with +`ma_node_graph_set_time()` which might be useful if you want to do seeking on a global timeline. +Getting and setting the local time is similar. Use `ma_node_get_time()` to retrieve the local time, +and `ma_node_set_time()` to set the local time. The global and local times will be advanced by the +audio thread, so care should be taken to avoid data races. Ideally you should avoid calling these +outside of the node processing callbacks which are always run on the audio thread. + +There is basic support for scheduling the starting and stopping of nodes. You can only schedule one +start and one stop at a time. This is mainly intended for putting nodes into a started or stopped +state in a frame-exact manner. Without this mechanism, starting and stopping of a node is limited +to the resolution of a call to `ma_node_graph_read_pcm_frames()` which would typically be in blocks +of several milliseconds. The following APIs can be used for scheduling node states: + + ```c + ma_node_set_state_time() + ma_node_get_state_time() + ``` + +The time is absolute and must be based on the global clock. An example is below: + + ```c + ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1); // Delay starting to 1 second. + ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5); // Delay stopping to 5 seconds. + ``` + +An example for changing the state using a relative time. + + ```c + ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1 + ma_node_graph_get_time(&myNodeGraph)); + ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5 + ma_node_graph_get_time(&myNodeGraph)); + ``` + +Note that due to the nature of multi-threading the times may not be 100% exact. If this is an +issue, consider scheduling state changes from within a processing callback. An idea might be to +have some kind of passthrough trigger node that is used specifically for tracking time and handling +events. + + + +7.2. Thread Safety and Locking +------------------------------ +When processing audio, it's ideal not to have any kind of locking in the audio thread. Since it's +expected that `ma_node_graph_read_pcm_frames()` would be run on the audio thread, it does so +without the use of any locks. This section discusses the implementation used by miniaudio and goes +over some of the compromises employed by miniaudio to achieve this goal. Note that the current +implementation may not be ideal - feedback and critiques are most welcome. + +The node graph API is not *entirely* lock-free. Only `ma_node_graph_read_pcm_frames()` is expected +to be lock-free. Attachment, detachment and uninitialization of nodes use locks to simplify the +implementation, but are crafted in a way such that such locking is not required when reading audio +data from the graph. Locking in these areas are achieved by means of spinlocks. + +The main complication with keeping `ma_node_graph_read_pcm_frames()` lock-free stems from the fact +that a node can be uninitialized, and it's memory potentially freed, while in the middle of being +processed on the audio thread. There are times when the audio thread will be referencing a node, +which means the uninitialization process of a node needs to make sure it delays returning until the +audio thread is finished so that control is not handed back to the caller thereby giving them a +chance to free the node's memory. + +When the audio thread is processing a node, it does so by reading from each of the output buses of +the node. In order for a node to process data for one of its output buses, it needs to read from +each of its input buses, and so on an so forth. It follows that once all output buses of a node +are detached, the node as a whole will be disconnected and no further processing will occur unless +it's output buses are reattached, which won't be happening when the node is being uninitialized. +By having `ma_node_detach_output_bus()` wait until the audio thread is finished with it, we can +simplify a few things, at the expense of making `ma_node_detach_output_bus()` a bit slower. By +doing this, the implementation of `ma_node_uninit()` becomes trivial - just detach all output +nodes, followed by each of the attachments to each of its input nodes, and then do any final clean +up. + +With the above design, the worst-case scenario is `ma_node_detach_output_bus()` taking as long as +it takes to process the output bus being detached. This will happen if it's called at just the +wrong moment where the audio thread has just iterated it and has just started processing. The +caller of `ma_node_detach_output_bus()` will stall until the audio thread is finished, which +includes the cost of recursively processing its inputs. This is the biggest compromise made with +the approach taken by miniaudio for its lock-free processing system. The cost of detaching nodes +earlier in the pipeline (data sources, for example) will be cheaper than the cost of detaching +higher level nodes, such as some kind of final post-processing endpoint. If you need to do mass +detachments, detach starting from the lowest level nodes and work your way towards the final +endpoint node (but don't try detaching the node graph's endpoint). If the audio thread is not +running, detachment will be fast and detachment in any order will be the same. The reason nodes +need to wait for their input attachments to complete is due to the potential for desyncs between +data sources. If the node was to terminate processing mid way through processing its inputs, +there's a chance that some of the underlying data sources will have been read, but then others not. +That will then result in a potential desynchronization when detaching and reattaching higher-level +nodes. A possible solution to this is to have an option when detaching to terminate processing +before processing all input attachments which should be fairly simple. + +Another compromise, albeit less significant, is locking when attaching and detaching nodes. This +locking is achieved by means of a spinlock in order to reduce memory overhead. A lock is present +for each input bus and output bus. When an output bus is connected to an input bus, both the output +bus and input bus is locked. This locking is specifically for attaching and detaching across +different threads and does not affect `ma_node_graph_read_pcm_frames()` in any way. The locking and +unlocking is mostly self-explanatory, but a slightly less intuitive aspect comes into it when +considering that iterating over attachments must not break as a result of attaching or detaching a +node while iteration is occurring. + +Attaching and detaching are both quite simple. When an output bus of a node is attached to an input +bus of another node, it's added to a linked list. Basically, an input bus is a linked list, where +each item in the list is and output bus. We have some intentional (and convenient) restrictions on +what can done with the linked list in order to simplify the implementation. First of all, whenever +something needs to iterate over the list, it must do so in a forward direction. Backwards iteration +is not supported. Also, items can only be added to the start of the list. + +The linked list is a doubly-linked list where each item in the list (an output bus) holds a pointer +to the next item in the list, and another to the previous item. A pointer to the previous item is +only required for fast detachment of the node - it is never used in iteration. This is an +important property because it means from the perspective of iteration, attaching and detaching of +an item can be done with a single atomic assignment. This is exploited by both the attachment and +detachment process. When attaching the node, the first thing that is done is the setting of the +local "next" and "previous" pointers of the node. After that, the item is "attached" to the list +by simply performing an atomic exchange with the head pointer. After that, the node is "attached" +to the list from the perspective of iteration. Even though the "previous" pointer of the next item +hasn't yet been set, from the perspective of iteration it's been attached because iteration will +only be happening in a forward direction which means the "previous" pointer won't actually ever get +used. The same general process applies to detachment. See `ma_node_attach_output_bus()` and +`ma_node_detach_output_bus()` for the implementation of this mechanism. + + + +8. Decoding +=========== +The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from +devices and can be used independently. Built-in support is included for the following formats: + + +---------+ + | Format | + +---------+ + | WAV | + | MP3 | + | FLAC | + +---------+ + +You can disable the built-in decoders by specifying one or more of the following options before the +miniaudio implementation: + + ```c + #define MA_NO_WAV + #define MA_NO_MP3 + #define MA_NO_FLAC + ``` + +miniaudio supports the ability to plug in custom decoders. See the section below for details on how +to use custom decoders. + +A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with +`ma_decoder_init_memory()`, or from data delivered via callbacks with `ma_decoder_init()`. Here is +an example for loading a decoder from a file: + + ```c + ma_decoder decoder; + ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder); + if (result != MA_SUCCESS) { + return false; // An error occurred. + } + + ... + + ma_decoder_uninit(&decoder); + ``` + +When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object +(the `NULL` argument in the example above) which allows you to configure the output format, channel +count, sample rate and channel map: + + ```c + ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000); + ``` + +When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the +same as that defined by the decoding backend. + +Data is read from the decoder as PCM frames. This will output the number of PCM frames actually +read. If this is less than the requested number of PCM frames it means you've reached the end. The +return value will be `MA_AT_END` if no samples have been read and the end has been reached. + + ```c + ma_result result = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead, &framesRead); + if (framesRead < framesToRead) { + // Reached the end. + } + ``` + +You can also seek to a specific frame like so: + + ```c + ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame); + if (result != MA_SUCCESS) { + return false; // An error occurred. + } + ``` + +If you want to loop back to the start, you can simply seek back to the first PCM frame: + + ```c + ma_decoder_seek_to_pcm_frame(pDecoder, 0); + ``` + +When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding +backend. This can be unnecessarily inefficient if the type is already known. In this case you can +use `encodingFormat` variable in the device config to specify a specific encoding format you want +to decode: + + ```c + decoderConfig.encodingFormat = ma_encoding_format_wav; + ``` + +See the `ma_encoding_format` enum for possible encoding formats. + +The `ma_decoder_init_file()` API will try using the file extension to determine which decoding +backend to prefer. + + +8.1. Custom Decoders +-------------------- +It's possible to implement a custom decoder and plug it into miniaudio. This is extremely useful +when you want to use the `ma_decoder` API, but need to support an encoding format that's not one of +the stock formats supported by miniaudio. This can be put to particularly good use when using the +`ma_engine` and/or `ma_resource_manager` APIs because they use `ma_decoder` internally. If, for +example, you wanted to support Opus, you can do so with a custom decoder (there if a reference +Opus decoder in the "extras" folder of the miniaudio repository which uses libopus + libopusfile). + +A custom decoder must implement a data source. A vtable called `ma_decoding_backend_vtable` needs +to be implemented which is then passed into the decoder config: + + ```c + ma_decoding_backend_vtable* pCustomBackendVTables[] = + { + &g_ma_decoding_backend_vtable_libvorbis, + &g_ma_decoding_backend_vtable_libopus + }; + + ... + + decoderConfig = ma_decoder_config_init_default(); + decoderConfig.pCustomBackendUserData = NULL; + decoderConfig.ppCustomBackendVTables = pCustomBackendVTables; + decoderConfig.customBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); + ``` + +The `ma_decoding_backend_vtable` vtable has the following functions: + + ``` + onInit + onInitFile + onInitFileW + onInitMemory + onUninit + ``` + +There are only two functions that must be implemented - `onInit` and `onUninit`. The other +functions can be implemented for a small optimization for loading from a file path or memory. If +these are not specified, miniaudio will deal with it for you via a generic implementation. + +When you initialize a custom data source (by implementing the `onInit` function in the vtable) you +will need to output a pointer to a `ma_data_source` which implements your custom decoder. See the +section about data sources for details on how to implement this. Alternatively, see the +"custom_decoders" example in the miniaudio repository. + +The `onInit` function takes a pointer to some callbacks for the purpose of reading raw audio data +from some arbitrary source. You'll use these functions to read from the raw data and perform the +decoding. When you call them, you will pass in the `pReadSeekTellUserData` pointer to the relevant +parameter. + +The `pConfig` parameter in `onInit` can be used to configure the backend if appropriate. It's only +used as a hint and can be ignored. However, if any of the properties are relevant to your decoder, +an optimal implementation will handle the relevant properties appropriately. + +If memory allocation is required, it should be done so via the specified allocation callbacks if +possible (the `pAllocationCallbacks` parameter). + +If an error occurs when initializing the decoder, you should leave `ppBackend` unset, or set to +NULL, and make sure everything is cleaned up appropriately and an appropriate result code returned. +When multiple custom backends are specified, miniaudio will cycle through the vtables in the order +they're listed in the array that's passed into the decoder config so it's important that your +initialization routine is clean. + +When a decoder is uninitialized, the `onUninit` callback will be fired which will give you an +opportunity to clean up and internal data. + + + +9. Encoding +=========== +The `ma_encoding` API is used for writing audio files. The only supported output format is WAV. +This can be disabled by specifying the following option before the implementation of miniaudio: + + ```c + #define MA_NO_WAV + ``` + +An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data +delivered via callbacks with `ma_encoder_init()`. Below is an example for initializing an encoder +to output to a file. + + ```c + ma_encoder_config config = ma_encoder_config_init(ma_encoding_format_wav, FORMAT, CHANNELS, SAMPLE_RATE); + ma_encoder encoder; + ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder); + if (result != MA_SUCCESS) { + // Error + } + + ... + + ma_encoder_uninit(&encoder); + ``` + +When initializing an encoder you must specify a config which is initialized with +`ma_encoder_config_init()`. Here you must specify the file type, the output sample format, output +channel count and output sample rate. The following file types are supported: + + +------------------------+-------------+ + | Enum | Description | + +------------------------+-------------+ + | ma_encoding_format_wav | WAV | + +------------------------+-------------+ + +If the format, channel count or sample rate is not supported by the output file type an error will +be returned. The encoder will not perform data conversion so you will need to convert it before +outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the +example below: + + ```c + ma_uint64 framesWritten; + result = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite, &framesWritten); + if (result != MA_SUCCESS) { + ... handle error ... + } + ``` + +The `framesWritten` variable will contain the number of PCM frames that were actually written. This +is optionally and you can pass in `NULL` if you need this. + +Encoders must be uninitialized with `ma_encoder_uninit()`. + + + +10. Data Conversion +=================== +A data conversion API is included with miniaudio which supports the majority of data conversion +requirements. This supports conversion between sample formats, channel counts (with channel +mapping) and sample rates. + + +10.1. Sample Format Conversion +------------------------------ +Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and +`ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()` to convert between two specific +formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use +`ma_convert_pcm_frames_format()` to convert PCM frames where you want to specify the frame count +and channel count as a variable instead of the total sample count. + + +10.1.1. Dithering +----------------- +Dithering can be set using the ditherMode parameter. + +The different dithering modes include the following, in order of efficiency: + + +-----------+--------------------------+ + | Type | Enum Token | + +-----------+--------------------------+ + | None | ma_dither_mode_none | + | Rectangle | ma_dither_mode_rectangle | + | Triangle | ma_dither_mode_triangle | + +-----------+--------------------------+ + +Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be +ignored for conversions where dithering is not needed. Dithering is available for the following +conversions: + + ``` + s16 -> u8 + s24 -> u8 + s32 -> u8 + f32 -> u8 + s24 -> s16 + s32 -> s16 + f32 -> s16 + ``` + +Note that it is not an error to pass something other than ma_dither_mode_none for conversions where +dither is not used. It will just be ignored. + + + +10.2. Channel Conversion +------------------------ +Channel conversion is used for channel rearrangement and conversion from one channel count to +another. The `ma_channel_converter` API is used for channel conversion. Below is an example of +initializing a simple channel converter which converts from mono to stereo. + + ```c + ma_channel_converter_config config = ma_channel_converter_config_init( + ma_format, // Sample format + 1, // Input channels + NULL, // Input channel map + 2, // Output channels + NULL, // Output channel map + ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels. + + result = ma_channel_converter_init(&config, NULL, &converter); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so: + + ```c + ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +It is up to the caller to ensure the output buffer is large enough to accommodate the new PCM +frames. + +Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. + + +10.2.1. Channel Mapping +----------------------- +In addition to converting from one channel count to another, like the example above, the channel +converter can also be used to rearrange channels. When initializing the channel converter, you can +optionally pass in channel maps for both the input and output frames. If the channel counts are the +same, and each channel map contains the same channel positions with the exception that they're in +a different order, a simple shuffling of the channels will be performed. If, however, there is not +a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed +based on a mixing mode which is specified when initializing the `ma_channel_converter_config` +object. + +When converting from mono to multi-channel, the mono channel is simply copied to each output +channel. When going the other way around, the audio of each output channel is simply averaged and +copied to the mono channel. + +In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess +channels and silence extra channels. For example, converting from 4 to 2 channels, the 3rd and 4th +channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and +4th channels. + +The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a +simple distribution between input and output. Imagine sitting in the middle of a room, with +speakers on the walls representing channel positions. The `MA_CHANNEL_FRONT_LEFT` position can be +thought of as being in the corner of the front and left walls. + +Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined +weights. Custom weights can be passed in as the last parameter of +`ma_channel_converter_config_init()`. + +Predefined channel maps can be retrieved with `ma_channel_map_init_standard()`. This takes a +`ma_standard_channel_map` enum as its first parameter, which can be one of the following: + + +-----------------------------------+-----------------------------------------------------------+ + | Name | Description | + +-----------------------------------+-----------------------------------------------------------+ + | ma_standard_channel_map_default | Default channel map used by miniaudio. See below. | + | ma_standard_channel_map_microsoft | Channel map used by Microsoft's bitfield channel maps. | + | ma_standard_channel_map_alsa | Default ALSA channel map. | + | ma_standard_channel_map_rfc3551 | RFC 3551.

This | + | | is equivalent to the same | + | | mapping as the device. | + +---------------+---------------------------------+ + + + +10.3. Resampling +---------------- +Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something +like the following: + + ```c + ma_resampler_config config = ma_resampler_config_init( + ma_format_s16, + channels, + sampleRateIn, + sampleRateOut, + ma_resample_algorithm_linear); + + ma_resampler resampler; + ma_result result = ma_resampler_init(&config, NULL, &resampler); + if (result != MA_SUCCESS) { + // An error occurred... + } + ``` + +Do the following to uninitialize the resampler: + + ```c + ma_resampler_uninit(&resampler); + ``` + +The following example shows how data can be processed + + ```c + ma_uint64 frameCountIn = 1000; + ma_uint64 frameCountOut = 2000; + ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); + if (result != MA_SUCCESS) { + // An error occurred... + } + + // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the + // number of output frames written. + ``` + +To initialize the resampler you first need to set up a config (`ma_resampler_config`) with +`ma_resampler_config_init()`. You need to specify the sample format you want to use, the number of +channels, the input and output sample rate, and the algorithm. + +The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format +you will need to perform pre- and post-conversions yourself where necessary. Note that the format +is the same for both input and output. The format cannot be changed after initialization. + +The resampler supports multiple channels and is always interleaved (both input and output). The +channel count cannot be changed after initialization. + +The sample rates can be anything other than zero, and are always specified in hertz. They should be +set to something like 44100, etc. The sample rate is the only configuration property that can be +changed after initialization. + +The miniaudio resampler has built-in support for the following algorithms: + + +-----------+------------------------------+ + | Algorithm | Enum Token | + +-----------+------------------------------+ + | Linear | ma_resample_algorithm_linear | + | Custom | ma_resample_algorithm_custom | + +-----------+------------------------------+ + +The algorithm cannot be changed after initialization. + +Processing always happens on a per PCM frame basis and always assumes interleaved input and output. +De-interleaved processing is not supported. To process frames, use +`ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you +can fit in the output buffer and the number of input frames contained in the input buffer. On +output these variables contain the number of output frames that were written to the output buffer +and the number of input frames that were consumed in the process. You can pass in NULL for the +input buffer in which case it will be treated as an infinitely large buffer of zeros. The output +buffer can also be NULL, in which case the processing will be treated as seek. + +The sample rate can be changed dynamically on the fly. You can change this with explicit sample +rates with `ma_resampler_set_rate()` and also with a decimal ratio with +`ma_resampler_set_rate_ratio()`. The ratio is in/out. + +Sometimes it's useful to know exactly how many input frames will be required to output a specific +number of frames. You can calculate this with `ma_resampler_get_required_input_frame_count()`. +Likewise, it's sometimes useful to know exactly how many frames would be output given a certain +number of input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`. + +Due to the nature of how resampling works, the resampler introduces some latency. This can be +retrieved in terms of both the input rate and the output rate with +`ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`. + + +10.3.1. Resampling Algorithms +----------------------------- +The choice of resampling algorithm depends on your situation and requirements. + + +10.3.1.1. Linear Resampling +--------------------------- +The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, +some control over the quality of the linear resampler which may make it a suitable option depending +on your requirements. + +The linear resampler performs low-pass filtering before or after downsampling or upsampling, +depending on the sample rates you're converting between. When decreasing the sample rate, the +low-pass filter will be applied before downsampling. When increasing the rate it will be performed +after upsampling. By default a fourth order low-pass filter will be applied. This can be configured +via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering. + +The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of +the input and output sample rates (Nyquist Frequency). + +The API for the linear resampler is the same as the main resampler API, only it's called +`ma_linear_resampler`. + + +10.3.2. Custom Resamplers +------------------------- +You can implement a custom resampler by using the `ma_resample_algorithm_custom` resampling +algorithm and setting a vtable in the resampler config: + + ```c + ma_resampler_config config = ma_resampler_config_init(..., ma_resample_algorithm_custom); + config.pBackendVTable = &g_customResamplerVTable; + ``` + +Custom resamplers are useful if the stock algorithms are not appropriate for your use case. You +need to implement the required functions in `ma_resampling_backend_vtable`. Note that not all +functions in the vtable need to be implemented, but if it's possible to implement, they should be. + +You can use the `ma_linear_resampler` object for an example on how to implement the vtable. The +`onGetHeapSize` callback is used to calculate the size of any internal heap allocation the custom +resampler will need to make given the supplied config. When you initialize the resampler via the +`onInit` callback, you'll be given a pointer to a heap allocation which is where you should store +the heap allocated data. You should not free this data in `onUninit` because miniaudio will manage +it for you. + +The `onProcess` callback is where the actual resampling takes place. On input, `pFrameCountIn` +points to a variable containing the number of frames in the `pFramesIn` buffer and +`pFrameCountOut` points to a variable containing the capacity in frames of the `pFramesOut` buffer. +On output, `pFrameCountIn` should be set to the number of input frames that were fully consumed, +whereas `pFrameCountOut` should be set to the number of frames that were written to `pFramesOut`. + +The `onSetRate` callback is optional and is used for dynamically changing the sample rate. If +dynamic rate changes are not supported, you can set this callback to NULL. + +The `onGetInputLatency` and `onGetOutputLatency` functions are used for retrieving the latency in +input and output rates respectively. These can be NULL in which case latency calculations will be +assumed to be NULL. + +The `onGetRequiredInputFrameCount` callback is used to give miniaudio a hint as to how many input +frames are required to be available to produce the given number of output frames. Likewise, the +`onGetExpectedOutputFrameCount` callback is used to determine how many output frames will be +produced given the specified number of input frames. miniaudio will use these as a hint, but they +are optional and can be set to NULL if you're unable to implement them. + + + +10.4. General Data Conversion +----------------------------- +The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and +resampling into one operation. This is what miniaudio uses internally to convert between the format +requested when the device was initialized and the format of the backend's native device. The API +for general data conversion is very similar to the resampling API. Create a `ma_data_converter` +object like this: + + ```c + ma_data_converter_config config = ma_data_converter_config_init( + inputFormat, + outputFormat, + inputChannels, + outputChannels, + inputSampleRate, + outputSampleRate + ); + + ma_data_converter converter; + ma_result result = ma_data_converter_init(&config, NULL, &converter); + if (result != MA_SUCCESS) { + // An error occurred... + } + ``` + +In the example above we use `ma_data_converter_config_init()` to initialize the config, however +there's many more properties that can be configured, such as channel maps and resampling quality. +Something like the following may be more suitable depending on your requirements: + + ```c + ma_data_converter_config config = ma_data_converter_config_init_default(); + config.formatIn = inputFormat; + config.formatOut = outputFormat; + config.channelsIn = inputChannels; + config.channelsOut = outputChannels; + config.sampleRateIn = inputSampleRate; + config.sampleRateOut = outputSampleRate; + ma_channel_map_init_standard(ma_standard_channel_map_flac, config.channelMapIn, sizeof(config.channelMapIn)/sizeof(config.channelMapIn[0]), config.channelCountIn); + config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER; + ``` + +Do the following to uninitialize the data converter: + + ```c + ma_data_converter_uninit(&converter, NULL); + ``` + +The following example shows how data can be processed + + ```c + ma_uint64 frameCountIn = 1000; + ma_uint64 frameCountOut = 2000; + ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); + if (result != MA_SUCCESS) { + // An error occurred... + } + + // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number + // of output frames written. + ``` + +The data converter supports multiple channels and is always interleaved (both input and output). +The channel count cannot be changed after initialization. + +Sample rates can be anything other than zero, and are always specified in hertz. They should be set +to something like 44100, etc. The sample rate is the only configuration property that can be +changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of +`ma_data_converter_config` is set to `MA_TRUE`. To change the sample rate, use +`ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. +The resampling algorithm cannot be changed after initialization. + +Processing always happens on a per PCM frame basis and always assumes interleaved input and output. +De-interleaved processing is not supported. To process frames, use +`ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames +you can fit in the output buffer and the number of input frames contained in the input buffer. On +output these variables contain the number of output frames that were written to the output buffer +and the number of input frames that were consumed in the process. You can pass in NULL for the +input buffer in which case it will be treated as an infinitely large +buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated +as seek. + +Sometimes it's useful to know exactly how many input frames will be required to output a specific +number of frames. You can calculate this with `ma_data_converter_get_required_input_frame_count()`. +Likewise, it's sometimes useful to know exactly how many frames would be output given a certain +number of input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`. + +Due to the nature of how resampling works, the data converter introduces some latency if resampling +is required. This can be retrieved in terms of both the input rate and the output rate with +`ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`. + + + +11. Filtering +============= + +11.1. Biquad Filtering +---------------------- +Biquad filtering is achieved with the `ma_biquad` API. Example: + + ```c + ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2); + ma_result result = ma_biquad_init(&config, NULL, &biquad); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount); + ``` + +Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, +b1 and b2, and the denominator coefficients are a0, a1 and a2. The a0 coefficient is required and +coefficients must not be pre-normalized. + +Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format +you need to convert it yourself beforehand. When using `ma_format_s16` the biquad filter will use +fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used. + +Input and output frames are always interleaved. + +Filtering can be applied in-place by passing in the same pointer for both the input and output +buffers, like so: + + ```c + ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount); + ``` + +If you need to change the values of the coefficients, but maintain the values in the registers you +can do so with `ma_biquad_reinit()`. This is useful if you need to change the properties of the +filter while keeping the values of registers valid to avoid glitching. Do not use +`ma_biquad_init()` for this as it will do a full initialization which involves clearing the +registers to 0. Note that changing the format or channel count after initialization is invalid and +will result in an error. + + +11.2. Low-Pass Filtering +------------------------ +Low-pass filtering is achieved with the following APIs: + + +---------+------------------------------------------+ + | API | Description | + +---------+------------------------------------------+ + | ma_lpf1 | First order low-pass filter | + | ma_lpf2 | Second order low-pass filter | + | ma_lpf | High order low-pass filter (Butterworth) | + +---------+------------------------------------------+ + +Low-pass filter example: + + ```c + ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order); + ma_result result = ma_lpf_init(&config, &lpf); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount); + ``` + +Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format +you need to convert it yourself beforehand. Input and output frames are always interleaved. + +Filtering can be applied in-place by passing in the same pointer for both the input and output +buffers, like so: + + ```c + ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount); + ``` + +The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, +you can chain first and second order filters together. + + ```c + for (iFilter = 0; iFilter < filterCount; iFilter += 1) { + ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount); + } + ``` + +If you need to change the configuration of the filter, but need to maintain the state of internal +registers you can do so with `ma_lpf_reinit()`. This may be useful if you need to change the sample +rate and/or cutoff frequency dynamically while maintaining smooth transitions. Note that changing the +format or channel count after initialization is invalid and will result in an error. + +The `ma_lpf` object supports a configurable order, but if you only need a first order filter you +may want to consider using `ma_lpf1`. Likewise, if you only need a second order filter you can use +`ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient. + +If an even filter order is specified, a series of second order filters will be processed in a +chain. If an odd filter order is specified, a first order filter will be applied, followed by a +series of second order filters in a chain. + + +11.3. High-Pass Filtering +------------------------- +High-pass filtering is achieved with the following APIs: + + +---------+-------------------------------------------+ + | API | Description | + +---------+-------------------------------------------+ + | ma_hpf1 | First order high-pass filter | + | ma_hpf2 | Second order high-pass filter | + | ma_hpf | High order high-pass filter (Butterworth) | + +---------+-------------------------------------------+ + +High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, +`ma_hpf2` and `ma_hpf`. See example code for low-pass filters for example usage. + + +11.4. Band-Pass Filtering +------------------------- +Band-pass filtering is achieved with the following APIs: + + +---------+-------------------------------+ + | API | Description | + +---------+-------------------------------+ + | ma_bpf2 | Second order band-pass filter | + | ma_bpf | High order band-pass filter | + +---------+-------------------------------+ + +Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and +`ma_hpf`. See example code for low-pass filters for example usage. Note that the order for +band-pass filters must be an even number which means there is no first order band-pass filter, +unlike low-pass and high-pass filters. + + +11.5. Notch Filtering +--------------------- +Notch filtering is achieved with the following APIs: + + +-----------+------------------------------------------+ + | API | Description | + +-----------+------------------------------------------+ + | ma_notch2 | Second order notching filter | + +-----------+------------------------------------------+ + + +11.6. Peaking EQ Filtering +------------------------- +Peaking filtering is achieved with the following APIs: + + +----------+------------------------------------------+ + | API | Description | + +----------+------------------------------------------+ + | ma_peak2 | Second order peaking filter | + +----------+------------------------------------------+ + + +11.7. Low Shelf Filtering +------------------------- +Low shelf filtering is achieved with the following APIs: + + +-------------+------------------------------------------+ + | API | Description | + +-------------+------------------------------------------+ + | ma_loshelf2 | Second order low shelf filter | + +-------------+------------------------------------------+ + +Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to +just turn them down rather than eliminate them entirely. + + +11.8. High Shelf Filtering +-------------------------- +High shelf filtering is achieved with the following APIs: + + +-------------+------------------------------------------+ + | API | Description | + +-------------+------------------------------------------+ + | ma_hishelf2 | Second order high shelf filter | + +-------------+------------------------------------------+ + +The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` +instead of `ma_loshelf`. Where a low shelf filter is used to adjust the volume of low frequencies, +the high shelf filter does the same thing for high frequencies. + + + + +12. Waveform and Noise Generation +================================= + +12.1. Waveforms +--------------- +miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved +with the `ma_waveform` API. Example: + + ```c + ma_waveform_config config = ma_waveform_config_init( + FORMAT, + CHANNELS, + SAMPLE_RATE, + ma_waveform_type_sine, + amplitude, + frequency); + + ma_waveform waveform; + ma_result result = ma_waveform_init(&config, &waveform); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount); + ``` + +The amplitude, frequency, type, and sample rate can be changed dynamically with +`ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`, `ma_waveform_set_type()`, and +`ma_waveform_set_sample_rate()` respectively. + +You can invert the waveform by setting the amplitude to a negative value. You can use this to +control whether or not a sawtooth has a positive or negative ramp, for example. + +Below are the supported waveform types: + + +---------------------------+ + | Enum Name | + +---------------------------+ + | ma_waveform_type_sine | + | ma_waveform_type_square | + | ma_waveform_type_triangle | + | ma_waveform_type_sawtooth | + +---------------------------+ + + + +12.2. Noise +----------- +miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example: + + ```c + ma_noise_config config = ma_noise_config_init( + FORMAT, + CHANNELS, + ma_noise_type_white, + SEED, + amplitude); + + ma_noise noise; + ma_result result = ma_noise_init(&config, &noise); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_noise_read_pcm_frames(&noise, pOutput, frameCount); + ``` + +The noise API uses simple LCG random number generation. It supports a custom seed which is useful +for things like automated testing requiring reproducibility. Setting the seed to zero will default +to `MA_DEFAULT_LCG_SEED`. + +The amplitude and seed can be changed dynamically with `ma_noise_set_amplitude()` and +`ma_noise_set_seed()` respectively. + +By default, the noise API will use different values for different channels. So, for example, the +left side in a stereo stream will be different to the right side. To instead have each channel use +the same random value, set the `duplicateChannels` member of the noise config to true, like so: + + ```c + config.duplicateChannels = MA_TRUE; + ``` + +Below are the supported noise types. + + +------------------------+ + | Enum Name | + +------------------------+ + | ma_noise_type_white | + | ma_noise_type_pink | + | ma_noise_type_brownian | + +------------------------+ + + + +13. Audio Buffers +================= +miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can +read from memory that's managed by the application, but can also handle the memory management for +you internally. Memory management is flexible and should support most use cases. + +Audio buffers are initialized using the standard configuration system used everywhere in miniaudio: + + ```c + ma_audio_buffer_config config = ma_audio_buffer_config_init( + format, + channels, + sizeInFrames, + pExistingData, + &allocationCallbacks); + + ma_audio_buffer buffer; + result = ma_audio_buffer_init(&config, &buffer); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_audio_buffer_uninit(&buffer); + ``` + +In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an +application can do self-managed memory allocation. If you would rather make a copy of the data, use +`ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`. + +Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the +raw audio data in a contiguous block of memory. That is, the raw audio data will be located +immediately after the `ma_audio_buffer` structure. To do this, use +`ma_audio_buffer_alloc_and_init()`: + + ```c + ma_audio_buffer_config config = ma_audio_buffer_config_init( + format, + channels, + sizeInFrames, + pExistingData, + &allocationCallbacks); + + ma_audio_buffer* pBuffer + result = ma_audio_buffer_alloc_and_init(&config, &pBuffer); + if (result != MA_SUCCESS) { + // Error + } + + ... + + ma_audio_buffer_uninit_and_free(&buffer); + ``` + +If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it +with `ma_audio_buffer_uninit_and_free()`. In the example above, the memory pointed to by +`pExistingData` will be copied into the buffer, which is contrary to the behavior of +`ma_audio_buffer_init()`. + +An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the +cursor moves forward. The last parameter (`loop`) can be used to determine if the buffer should +loop. The return value is the number of frames actually read. If this is less than the number of +frames requested it means the end has been reached. This should never happen if the `loop` +parameter is set to true. If you want to manually loop back to the start, you can do so with with +`ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an +audio buffer. + + ```c + ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping); + if (framesRead < desiredFrameCount) { + // If not looping, this means the end has been reached. This should never happen in looping mode with valid input. + } + ``` + +Sometimes you may want to avoid the cost of data movement between the internal buffer and the +output buffer. Instead you can use memory mapping to retrieve a pointer to a segment of data: + + ```c + void* pMappedFrames; + ma_uint64 frameCount = frameCountToTryMapping; + ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount); + if (result == MA_SUCCESS) { + // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be + // less due to the end of the buffer being reached. + ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels); + + // You must unmap the buffer. + ma_audio_buffer_unmap(pAudioBuffer, frameCount); + } + ``` + +When you use memory mapping, the read cursor is increment by the frame count passed in to +`ma_audio_buffer_unmap()`. If you decide not to process every frame you can pass in a value smaller +than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is +that it does not handle looping for you. You can determine if the buffer is at the end for the +purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of +`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` +as an error when returned by `ma_audio_buffer_unmap()`. + + + +14. Ring Buffers +================ +miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via +the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates on bytes, whereas the `ma_pcm_rb` +operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around +`ma_rb`. + +Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved +streams. The caller can also allocate their own backing memory for the ring buffer to use +internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for +you. + +The examples below use the PCM frame variant of the ring buffer since that's most likely the one +you will want to use. To initialize a ring buffer, do something like the following: + + ```c + ma_pcm_rb rb; + ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb); + if (result != MA_SUCCESS) { + // Error + } + ``` + +The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because +it's the PCM variant of the ring buffer API. For the regular ring buffer that operates on bytes you +would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes +instead of frames. The fourth parameter is an optional pre-allocated buffer and the fifth parameter +is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation routines. +Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used. + +Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is +offset from each other based on the stride. To manage your sub-buffers you can use +`ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and +`ma_pcm_rb_get_subbuffer_ptr()`. + +Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section +of the ring buffer. You specify the number of frames you need, and on output it will set to what +was actually acquired. If the read or write pointer is positioned such that the number of frames +requested will require a loop, it will be clamped to the end of the buffer. Therefore, the number +of frames you're given may be less than the number you requested. + +After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the +buffer and then "commit" it with `ma_pcm_rb_commit_read()` or `ma_pcm_rb_commit_write()`. This is +where the read/write pointers are updated. When you commit you need to pass in the buffer that was +returned by the earlier call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is +only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and +`ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was +originally requested. + +If you want to correct for drift between the write pointer and the read pointer you can use a +combination of `ma_pcm_rb_pointer_distance()`, `ma_pcm_rb_seek_read()` and +`ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only +move the read pointer forward via the consumer thread, and the write pointer forward by the +producer thread. If there is too much space between the pointers, move the read pointer forward. If +there is too little space between the pointers, move the write pointer forward. + +You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` +API. This is exactly the same, only you will use the `ma_rb` functions instead of `ma_pcm_rb` and +instead of frame counts you will pass around byte counts. + +The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most +significant bit being used to encode a loop flag and the internally managed buffers always being +aligned to `MA_SIMD_ALIGNMENT`. + +Note that the ring buffer is only thread safe when used by a single consumer thread and single +producer thread. + + + +15. Backends +============ +The following backends are supported by miniaudio. These are listed in order of default priority. +When no backend is specified when initializing a context or device, miniaudio will attempt to use +each of these backends in the order listed in the table below. + +Note that backends that are not usable by the build target will not be included in the build. For +example, ALSA, which is specific to Linux, will not be included in the Windows build. + + +-------------+-----------------------+--------------------------------------------------------+ + | Name | Enum Name | Supported Operating Systems | + +-------------+-----------------------+--------------------------------------------------------+ + | WASAPI | ma_backend_wasapi | Windows Vista+ | + | DirectSound | ma_backend_dsound | Windows XP+ | + | WinMM | ma_backend_winmm | Windows 95+ | + | Core Audio | ma_backend_coreaudio | macOS, iOS | + | sndio | ma_backend_sndio | OpenBSD | + | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | + | OSS | ma_backend_oss | FreeBSD | + | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | + | ALSA | ma_backend_alsa | Linux | + | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | + | AAudio | ma_backend_aaudio | Android 8+ | + | OpenSL ES | ma_backend_opensl | Android (API level 16+) | + | Web Audio | ma_backend_webaudio | Web (via Emscripten) | + | Custom | ma_backend_custom | Cross Platform | + | Null | ma_backend_null | Cross Platform (not used on Web) | + +-------------+-----------------------+--------------------------------------------------------+ + +Some backends have some nuance details you may want to be aware of. + +15.1. WASAPI +------------ +- Low-latency shared mode will be disabled when using an application-defined sample rate which is + different to the device's native sample rate. To work around this, set `wasapi.noAutoConvertSRC` + to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing + when the `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC + will result in miniaudio's internal resampler being used instead which will in turn enable the + use of low-latency shared mode. + +15.2. PulseAudio +---------------- +- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki: + https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. + Alternatively, consider using a different backend such as ALSA. + +15.3. Android +------------- +- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: + `` +- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a + limitation with OpenSL|ES. +- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration + API (devices are enumerated through Java). You can however perform your own device enumeration + through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it + to ma_device_init(). +- The backend API will perform resampling where possible. The reason for this as opposed to using + miniaudio's built-in resampler is to take advantage of any potential device-specific + optimizations the driver may implement. + +BSD +--- +- The sndio backend is currently only enabled on OpenBSD builds. +- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can + use it. + +15.4. UWP +--------- +- UWP only supports default playback and capture devices. +- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): + + ``` + + ... + + + + + ``` + +15.5. Web Audio / Emscripten +---------------------------- +- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build. +- The first time a context is initialized it will create a global object called "miniaudio" whose + primary purpose is to act as a factory for device objects. +- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as + they've been deprecated. +- Google has implemented a policy in their browsers that prevent automatic media output without + first receiving some kind of user input. The following web page has additional details: + https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device + may fail if you try to start playback without first handling some kind of user input. + + + +16. Optimization Tips +===================== +See below for some tips on improving performance. + +16.1. Low Level API +------------------- +- In the data callback, if your data is already clipped prior to copying it into the output buffer, + set the `noClip` config option in the device config to true. This will disable miniaudio's built + in clipping function. +- By default, miniaudio will pre-silence the data callback's output buffer. If you know that you + will always write valid data to the output buffer you can disable pre-silencing by setting the + `noPreSilence` config option in the device config to true. + +16.2. High Level API +-------------------- +- If a sound does not require doppler or pitch shifting, consider disabling pitching by + initializing the sound with the `MA_SOUND_FLAG_NO_PITCH` flag. +- If a sound does not require spatialization, disable it by initializing the sound with the + `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. It can be re-enabled again post-initialization with + `ma_sound_set_spatialization_enabled()`. +- If you know all of your sounds will always be the same sample rate, set the engine's sample + rate to match that of the sounds. Likewise, if you're using a self-managed resource manager, + consider setting the decoded sample rate to match your sounds. By configuring everything to + use a consistent sample rate, sample rate conversion can be avoided. + + + +17. Miscellaneous Notes +======================= +- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for + WASAPI and Core Audio, however other backends such as PulseAudio may naturally support it, though + not all have been tested. +- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This + is due to 64-bit file APIs not being available. +*/ + +#ifndef miniaudio_h +#define miniaudio_h + +#ifdef __cplusplus +extern "C" { +#endif + +#define MA_STRINGIFY(x) #x +#define MA_XSTRINGIFY(x) MA_STRINGIFY(x) + +#define MA_VERSION_MAJOR 0 +#define MA_VERSION_MINOR 11 +#define MA_VERSION_REVISION 23 +#define MA_VERSION_STRING MA_XSTRINGIFY(MA_VERSION_MAJOR) "."

They will be named like so: + + ma_atomic_uint32 - atomic ma_uint32 + ma_atomic_int32 - atomic ma_int32 + ma_atomic_uint64 - atomic ma_uint64 + ma_atomic_float - atomic float + ma_atomic_bool32 - atomic ma_bool32 + +The other downside is that atomic pointers are extremely messy. You need to declare a new struct for each specific +type of pointer you need to make atomic. For example, an atomic ma_node* will look like this: + + MA_ATOMIC_SAFE_TYPE_IMPL_PTR(node) + +Which will declare a type struct that's named like so: + + ma_atomic_ptr_node + +Functions to use the atomic types are declared in the implementation section. All atomic functions are prefixed with +the name of the struct. For example: + + ma_atomic_uint32_set() - Atomic store of ma_uint32 + ma_atomic_uint32_get() - Atomic load of ma_uint32 + etc. + +For pointer types it's the same, which makes them a bit messy to use due to the length of each function name, but in +return you get type safety and enforcement of atomic operations. +*/ +#define MA_ATOMIC_SAFE_TYPE_DECL(c89TypeExtension, typeSize, type) \ + typedef struct \ + { \ + MA_ATOMIC(typeSize, ma_##type) value; \ + } ma_atomic_##type; \ + +#define MA_ATOMIC_SAFE_TYPE_DECL_PTR(type) \ + typedef struct \ + { \ + MA_ATOMIC(MA_SIZEOF_PTR, ma_##type*) value; \ + } ma_atomic_ptr_##type; \ + +MA_ATOMIC_SAFE_TYPE_DECL(32, 4, uint32) +MA_ATOMIC_SAFE_TYPE_DECL(i32, 4, int32) +MA_ATOMIC_SAFE_TYPE_DECL(64, 8, uint64) +MA_ATOMIC_SAFE_TYPE_DECL(f32, 4, float) +MA_ATOMIC_SAFE_TYPE_DECL(32, 4, bool32) + + +/* Spinlocks are 32-bit for compatibility reasons. */ +typedef ma_uint32 ma_spinlock; + +#ifndef MA_NO_THREADING + /* Thread priorities should be ordered such that the default priority of the worker thread is 0. */ + typedef enum + { + ma_thread_priority_idle = -5, + ma_thread_priority_lowest = -4, + ma_thread_priority_low = -3, + ma_thread_priority_normal = -2, + ma_thread_priority_high = -1, + ma_thread_priority_highest = 0, + ma_thread_priority_realtime = 1, + ma_thread_priority_default = 0 + } ma_thread_priority; + + #if defined(MA_POSIX) + typedef ma_pthread_t ma_thread; + #elif defined(MA_WIN32) + typedef ma_handle ma_thread; + #endif + + #if defined(MA_POSIX) + typedef ma_pthread_mutex_t ma_mutex; + #elif defined(MA_WIN32) + typedef ma_handle ma_mutex; + #endif + + #if defined(MA_POSIX) + typedef struct + { + ma_uint32 value; + ma_pthread_mutex_t lock; + ma_pthread_cond_t cond; + } ma_event; + #elif defined(MA_WIN32) + typedef ma_handle ma_event; + #endif + + #if defined(MA_POSIX) + typedef struct + { + int value; + ma_pthread_mutex_t lock; + ma_pthread_cond_t cond; + } ma_semaphore; + #elif defined(MA_WIN32) + typedef ma_handle ma_semaphore; + #endif +#else + /* MA_NO_THREADING is set which means threading is disabled.

These callbacks are grouped into two parts: context and device. There is one context +to many devices. A device is created from a context. + +The general flow goes like this: + + 1) A context is created with `onContextInit()` + 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required. + 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required. + 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was + selected from device enumeration via `onContextEnumerateDevices()`. + 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()` + 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call + to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by + miniaudio internally. + +Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the +callbacks defined in this structure. + +Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which +physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the +given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration +needs to stop and the `onContextEnumerateDevices()` function returns with a success code. + +Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID, +and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the +case when the device ID is NULL, in which case information about the default device needs to be retrieved. + +Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created. +This is a little bit more complicated than initialization of the context due to its more complicated configuration. When initializing a +device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input, +the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to +the requested format. The conversion between the format requested by the application and the device's native format will be handled +internally by miniaudio. + +On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's +supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for +sample rate. For the channel map, the default should be used when `ma_channel_map_is_blank()` returns true (all channels set to +`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should +inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period +size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the +sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_descriptor` +object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set). + +Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses +asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented. + +The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit +easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and +`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the +backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within its callback. +This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback. + +If the backend requires absolute flexibility with its data delivery, it can optionally implement the `onDeviceDataLoop()` callback +which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional. + +The audio thread should run data delivery logic in a loop while `ma_device_get_state() == ma_device_state_started` and no errors have been +encountered. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback. + +The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this +callback. When the device is stopped, the `ma_device_get_state() == ma_device_state_started` condition will fail and the loop will be terminated +which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback, +look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to +wake up the audio thread. + +If the backend supports an optimized retrieval of device information from an initialized `ma_device` object, it should implement the +`onDeviceGetInfo()` callback. This is optional, in which case it will fall back to `onContextGetDeviceInfo()` which is less efficient. +*/ +struct ma_backend_callbacks +{ + ma_result (* onContextInit)(ma_context* pContext, const ma_context_config* pConfig, ma_backend_callbacks* pCallbacks); + ma_result (* onContextUninit)(ma_context* pContext); + ma_result (* onContextEnumerateDevices)(ma_context* pContext, ma_enum_devices_callback_proc callback, void* pUserData); + ma_result (* onContextGetDeviceInfo)(ma_context* pContext, ma_device_type deviceType, const ma_device_id* pDeviceID, ma_device_info* pDeviceInfo); + ma_result (* onDeviceInit)(ma_device* pDevice, const ma_device_config* pConfig, ma_device_descriptor* pDescriptorPlayback, ma_device_descriptor* pDescriptorCapture); + ma_result (* onDeviceUninit)(ma_device* pDevice); + ma_result (* onDeviceStart)(ma_device* pDevice); + ma_result (* onDeviceStop)(ma_device* pDevice); + ma_result (* onDeviceRead)(ma_device* pDevice, void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesRead); + ma_result (* onDeviceWrite)(ma_device* pDevice, const void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesWritten); + ma_result (* onDeviceDataLoop)(ma_device* pDevice); + ma_result (* onDeviceDataLoopWakeup)(ma_device* pDevice); + ma_result (* onDeviceGetInfo)(ma_device* pDevice, ma_device_type type, ma_device_info* pDeviceInfo); +}; + +struct ma_context_config +{ + ma_log* pLog; + ma_thread_priority threadPriority; + size_t threadStackSize; + void* pUserData; + ma_allocation_callbacks allocationCallbacks; + struct + { + ma_handle hWnd; /* HWND.

The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it +from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be +playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.)

If both are 0 the default buffer size will be + used depending on the selected performance profile. The value affects latency. See below for details. + + periods + The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by + this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured. + + performanceProfile + A hint to miniaudio as to the performance requirements of your program.

This mainly affects the size of default buffers and can usually be left at its default value. + + noPreSilencedOutputBuffer + When set to true, the contents of the output buffer passed into the data callback will be left undefined.

You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data + callback will write to every sample in the output buffer, or if you are doing your own clearing. + + noClip + When set to true, the contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or + not to clip.

You can access this directly from the device object like `device.pUserData`. + + resampling.algorithm + The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The + default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`. + + resampling.pBackendVTable + A pointer to an optional vtable that can be used for plugging in a custom resampler. + + resampling.pBackendUserData + A pointer that will passed to callbacks in pBackendVTable. + + resampling.linear.lpfOrder + The linear resampler applies a low-pass filter as part of its processing for anti-aliasing. This setting controls the order of the filter. The higher + the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is + `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`. + + playback.pDeviceID + A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's + default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. + + playback.format + The sample format to use for playback.

Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify + exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to + ma_share_mode_shared and reinitializing. + + capture.pDeviceID + A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize.

Note that if you specify + exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to + ma_share_mode_shared and reinitializing. + + wasapi.noAutoConvertSRC + WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. + + wasapi.noDefaultQualitySRC + WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`. + You should usually leave this set to false, which is the default. + + wasapi.noAutoStreamRouting + WASAPI only.

Defaults to false. + + pulse.pStreamNamePlayback + PulseAudio only. Sets the stream name for playback. + + pulse.pStreamNameCapture + PulseAudio only. Sets the stream name for capture. + + pulse.channelMap + PulseAudio only. Sets the channel map that is requested from PulseAudio. See MA_PA_CHANNEL_MAP_* constants. Defaults to MA_PA_CHANNEL_MAP_AIFF. + + coreaudio.allowNominalSampleRateChange + Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This + is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate + that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will + find the closest match between the sample rate requested in the device config and the sample rates natively supported by the + hardware. When set to false, the sample rate currently set by the operating system will always be used. + + opensl.streamType + OpenSL only. Explicitly sets the stream type. If left unset (`ma_opensl_stream_type_default`), the + stream type will be left unset. Think of this as the type of audio you're playing. + + opensl.recordingPreset + OpenSL only. Explicitly sets the type of recording your program will be doing. When left + unset, the recording preset will be left unchanged. + + aaudio.usage + AAudio only. Explicitly sets the nature of the audio the program will be consuming. When + left unset, the usage will be left unchanged. + + aaudio.contentType + AAudio only. Sets the content type. When left unset, the content type will be left unchanged. + + aaudio.inputPreset + AAudio only. Explicitly sets the type of recording your program will be doing. When left + unset, the input preset will be left unchanged. + + aaudio.noAutoStartAfterReroute + AAudio only. Controls whether or not the device should be automatically restarted after a + stream reroute. When set to false (default) the device will be restarted automatically; + otherwise the device will be stopped. + + +Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device. + +After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. + +If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or +`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or +`ma_performance_profile_conservative`. + +If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device +in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the +config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA, +for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user. +Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary. + +When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config +and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run +on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`, +`playback/capture.channels` and `sampleRate` members of the device object. + +When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message +asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information. + +ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture. +If these fail it will try falling back to the "hw" device. + + +Example 1 - Simple Initialization +--------------------------------- +This example shows how to initialize a simple playback device using a standard configuration.

This is a brief description of what's going on +in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion. + +PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it +allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it +appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or +write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the +simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient +when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API. + +Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to +get fun, and I don't mean that in a good way... + +The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands +don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is +enabled through the use of a "main loop". In the asynchronous API you cannot get away from the main loop, and the main loop is where almost +all of PulseAudio's problems stem from. + +When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own +vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called +pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop +because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use +it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed. + +To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer +to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded +main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely +specialized such as if you want to integrate it into your application's existing main loop infrastructure. + +(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262. +It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.) + +Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to +miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's +one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which +is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if +you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()` +has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can +set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop. +All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected. +This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before +attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`. + +The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an +internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the +host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind. + +Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device. +The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call +`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get +information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object +is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to +run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the +context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up. +All of that just to retrieve basic information about a device! + +Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the +context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design +choices in PulseAudio. + +PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here +because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for +writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can +set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices +straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified, +PulseAudio will immediately fire its write or read callback. This is *technically* correct (based on the wording in the documentation) +because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback +would be where a program will want to write or read data to or from the stream, but when it's called before the application has even +requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at +that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the +stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data +callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio +doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been +started. The device state is used for this - if the state is anything other than `ma_device_state_starting` or `ma_device_state_started`, the main data +callback is not fired. + +This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will +continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device +is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in +PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call +`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always +writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if +you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to +*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining +important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained +before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write +data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again! + +This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not* +write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just +resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This +disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the +callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.) + +Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context, +only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as +"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think +it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you +guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is +absolutely beyond me. Would it really be that hard to just make it run synchronously? + +Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that +they were initialized in. + +That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're +embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to +run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche +requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is +constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a +parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These +changes alone will change PulseAudio from one of the worst audio APIs to one of the best. +*/ + + +/* +It is assumed pulseaudio.h is available when linking at compile time.

For my own purposes, and for anybody out there whose +needing to figure out how this darn thing works, I'm going to outline a few things here. + +Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be +able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen +that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent +and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the +distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API. + +Most (all?) functions in the AudioObject API take a AudioObjectID as its input. This is the device identifier. When +retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific +data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the +devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be +the central APIs for retrieving information about the system and specific devices. + +To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a +structure with three variables and is used to identify which property you are getting or setting. The first is the "selector" +which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is +typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and +kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to +kAudioObjectPropertyElementMain in miniaudio's case. I don't know of any cases where this would be set to anything different. + +Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size +of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property +address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the +size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of +AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count. +*/ + +#if defined(MA_APPLE_MOBILE) +static void ma_device__on_notification_interruption_began(ma_device* pDevice) +{ + ma_device__on_notification(ma_device_notification_init(pDevice, ma_device_notification_type_interruption_began));

For many types of audio signals this compression +is "transparent", i.e. the difference from the original file is often not +audible. + +QOA encodes 20 samples of 16 bit PCM data into slices of 64 bits. A single +sample therefore requires 3.2 bits of storage space, resulting in a 5x +compression (16 / 3.2). + +A QOA file consists of an 8 byte file header, followed by a number of frames. +Each frame contains an 8 byte frame header, the current 16 byte en-/decoder +state per channel and 256 slices per channel. Each slice is 8 bytes wide and +encodes 20 samples of audio data. + +All values, including the slices, are big endian. The file layout is as follows: + +struct { + struct { + char magic[4]; // magic bytes "qoaf" + uint32_t samples; // samples per channel in this file + } file_header; + + struct { + struct { + uint8_t num_channels; // no. of channels + uint24_t samplerate; // samplerate in hz + uint16_t fsamples; // samples per channel in this frame + uint16_t fsize; // frame size (includes this header) + } frame_header; + + struct { + int16_t history[4]; // most recent last + int16_t weights[4]; // most recent last + } lms_state[num_channels]; + + qoa_slice_t slices[256][num_channels]; + + } frames[ceil(samples / (256 * 20))]; +} qoa_file_t; + +Each `qoa_slice_t` contains a quantized scalefactor `sf_quant` and 20 quantized +residuals `qrNN`: + +.- QOA_SLICE -- 64 bits, 20 samples --------------------------/ /------------. +| Byte[0] | Byte[1] | Byte[2] \ \ Byte[7] | +| 7 6 5 4 3 2 1 0 | 7 6 5 4 3 2 1 0 | 7 6 5 / / 2 1 0 | +|------------+--------+--------+--------+---------+---------+-\ \--+---------| +| sf_quant | qr00 | qr01 | qr02 | qr03 | qr04 | / / | qr19 | +`-------------------------------------------------------------\ \------------` + +Each frame except the last must contain exactly 256 slices per channel. The last +frame may contain between 1 .. 256 (inclusive) slices per channel. The last +slice (for each channel) in the last frame may contain less than 20 samples; the +slice still must be 8 bytes wide, with the unused samples zeroed out. + +Channels are interleaved per slice. E.g. for 2 channel stereo: +slice[0] = L, slice[1] = R, slice[2] = L, slice[3] = R ... + +A valid QOA file or stream must have at least one frame. Each frame must contain +at least one channel and one sample with a samplerate between 1 .. 16777215 +(inclusive). + +If the total number of samples is not known by the encoder, the samples in the +file header may be set to 0x00000000 to indicate that the encoder is +"streaming". In a streaming context, the samplerate and number of channels may +differ from frame to frame. For static files (those with samples set to a +non-zero value), each frame must have the same number of channels and same +samplerate. + +Note that this implementation of QOA only handles files with a known total +number of samples. + +A decoder should support at least 8 channels.

+/********************************************************************************************** +* +* rlsw v1.0 - An OpenGL 1.1-style software renderer implementation +* +* DESCRIPTION: +* rlsw is a custom OpenGL 1.1-style implementation on software, intended to provide all +* functionality available on rlgl.h library used by raylib, becoming a direct software +* rendering replacement for OpenGL 1.1 backend and allowing to run raylib on GPU-less +* devices when required. +* +* FEATURES: +* - Rendering to custom internal framebuffer with multiple color modes supported: +* - Color buffer: RGB - 8-bit (3:3:2) | RGB - 16-bit (5:6:5) | RGB - 24-bit (8:8:8) +* - Depth buffer: D - 8-bit (unorm) | D - 16-bit (unorm) | D - 24-bit (unorm) +* - Rendering modes supported: POINT, LINES, TRIANGLE, QUADS +* - Additional features: Polygon modes, Point width, Line width +* - Clipping support for all rendering modes +* - Texture features supported: +* - All uncompressed texture formats supported by raylib +* - Texture Minification/Magnification checks +* - Point and Bilinear filtering +* - Texture Wrap Modes with separate checks for S/T coordinates +* - Vertex Arrays support with direct primitive drawing mode +* - Matrix Stack support (Matrix Push/Pop) +* - Other GL misc features: +* - GL-style getter functions +* - Framebuffer resizing +* - Perspective correction +* - Scissor clipping +* - Depth testing +* - Blend modes +* - Face culling +* +* ADDITIONAL NOTES: +* Check PR for more info: https://github.com/raysan5/raylib/pull/4832 +* +* CONFIGURATION: +* #define RLSW_IMPLEMENTATION +* Generates the implementation of the library into the included file +* If not defined, the library is in header only mode and can be included in other headers +* or source files without problems. But only ONE file should hold the implementation +* +* rlsw capabilities could be customized just defining some internal +* values before library inclusion (default values listed): +* +* #define SW_GL_FRAMEBUFFER_COPY_BGRA true +* #define SW_GL_BINDING_COPY_TEXTURE true +* #define SW_COLOR_BUFFER_BITS 24 +* #define SW_DEPTH_BUFFER_BITS 16 +* #define SW_MAX_PROJECTION_STACK_SIZE 2 +* #define SW_MAX_MODELVIEW_STACK_SIZE 8 +* #define SW_MAX_TEXTURE_STACK_SIZE 2 +* #define SW_MAX_TEXTURES 128 +* +* +* LICENSE: MIT +* +* Copyright (c) 2025-2026 Le Juez Victor (@Bigfoot71), reviewed by Ramon Santamaria (@raysan5) +* +* Permission is hereby granted, free of charge, to any person obtaining a copy +* of this software and associated documentation files (the "Software"), to deal +* in the Software without restriction, including without limitation the rights +* to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +* copies of the Software, and to permit persons to whom the Software is +* furnished to do so, subject to the following conditions: +* +* The above copyright notice and this permission notice shall be included in all +* copies or substantial portions of the Software. +* +* THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +* IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +* FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Define STBI_NO_FAILURE_STRINGS +// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly +// more user-friendly ones. +// +// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. +// +// To query the width, height and component count of an image without having to +// decode the full file, you can use the stbi_info family of functions: +// +// int x,y,n,ok; +// ok = stbi_info(filename, &x, &y, &n); +// // returns ok=1 and sets x, y, n if image is a supported format, +// // 0 otherwise. +// +// Note that stb_image pervasively uses ints in its public API for sizes, +// including sizes of memory buffers. This is now part of the API and thus +// hard to change without causing breakage. As a result, the various image +// loaders all have certain limits on image size; these differ somewhat +// by format but generally boil down to either just under 2GB or just under +// 1GB. When the decoded image would be larger than this, stb_image decoding +// will fail. +// +// Additionally, stb_image will reject image files that have any of their +// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, +// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, +// the only way to have an image with such dimensions load correctly +// is for it to have a rather extreme aspect ratio. Either way, the +// assumption here is that such larger images are likely to be malformed +// or malicious. If you do need to load an image with individual dimensions +// larger than that, and it still fits in the overall size limit, you can +// #define STBI_MAX_DIMENSIONS on your own to be something larger. +// +// =========================================================================== +// +// UNICODE: +// +// If compiling for Windows and you wish to use Unicode filenames, compile +// with +// #define STBI_WINDOWS_UTF8 +// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert +// Windows wchar_t filenames to utf8. +// +// =========================================================================== +// +// Philosophy +// +// stb libraries are designed with the following priorities: +// +// 1. easy to use +// 2. easy to maintain +// 3. good performance +// +// Sometimes I let "good performance" creep up in priority over "easy to maintain", +// and for best performance I may provide less-easy-to-use APIs that give higher +// performance, in addition to the easy-to-use ones. Nevertheless, it's important +// to keep in mind that from the standpoint of you, a client of this library, +// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. +// +// Some secondary priorities arise directly from the first two, some of which +// provide more explicit reasons why performance can't be emphasized. +// +// - Portable ("ease of use") +// - Small source code footprint ("easy to maintain") +// - No dependencies ("ease of use") +// +// =========================================================================== +// +// I/O callbacks +// +// I/O callbacks allow you to read from arbitrary sources, like packaged +// files or some other source. Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image supports loading HDR images in general, and currently the Radiance +// .HDR file format specifically. You can still load any file through the existing +// interface; if you attempt to load an HDR file, it will be automatically remapped +// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// We optionally support converting iPhone-formatted PNGs (which store +// premultiplied BGRA) back to RGB, even though they're internally encoded +// differently. To enable this conversion, call +// stbi_convert_iphone_png_to_rgb(1). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// +// =========================================================================== +// +// ADDITIONAL CONFIGURATION +// +// - You can suppress implementation of any of the decoders to reduce +// your code footprint by #defining one or more of the following +// symbols before creating the implementation. +// +// STBI_NO_JPEG +// STBI_NO_PNG +// STBI_NO_BMP +// STBI_NO_PSD +// STBI_NO_TGA +// STBI_NO_GIF +// STBI_NO_HDR +// STBI_NO_PIC +// STBI_NO_PNM (.ppm and .pgm) +// +// - You can request *only* certain decoders and suppress all other ones +// (this will be more forward-compatible, as addition of new decoders +// doesn't require you to disable them explicitly): +// +// STBI_ONLY_JPEG +// STBI_ONLY_PNG +// STBI_ONLY_BMP +// STBI_ONLY_PSD +// STBI_ONLY_TGA +// STBI_ONLY_GIF +// STBI_ONLY_HDR +// STBI_ONLY_PIC +// STBI_ONLY_PNM (.ppm and .pgm) +// +// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still +// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB +// +// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater +// than that size (in either width or height) without further processing. +// This is to let programs in the wild set an upper bound to prevent +// denial-of-service attacks on untrusted data, as one could generate a +// valid image of gigantic dimensions and force stb_image to allocate a +// huge block of memory and spend disproportionate time decoding it.

To override the + memory allocation, before the implementation #include, add a: + + #define STBIR_MALLOC(size,user_data) ... + #define STBIR_FREE(ptr,user_data) ... + + Each resize makes exactly one call to malloc/free (unless you use the + extended API where you can do one allocation for many resizes). Under + address sanitizer, we do separate allocations to find overread/writes. + + PERFORMANCE + This library was written with an emphasis on performance. When testing + stb_image_resize with RGBA, the fastest mode is STBIR_4CHANNEL with + STBIR_TYPE_UINT8 pixels and CLAMPed edges (which is what many other resize + libs do by default). Also, make sure SIMD is turned on of course (default + for 64-bit targets). Avoid WRAP edge mode if you want the fastest speed. + + This library also comes with profiling built-in. If you define STBIR_PROFILE, + you can use the advanced API and get low-level profiling information by + calling stbir_resize_extended_profile_info() or stbir_resize_split_profile_info() + after a resize. + + SIMD + Most of the routines have optimized SSE2, AVX, NEON and WASM versions. + + On Microsoft compilers, we automatically turn on SIMD for 64-bit x64 and + ARM; for 32-bit x86 and ARM, you select SIMD mode by defining STBIR_SSE2 or + STBIR_NEON. For AVX and AVX2, we auto-select it by detecting the /arch:AVX + or /arch:AVX2 switches. You can also always manually turn SSE2, AVX or AVX2 + support on by defining STBIR_SSE2, STBIR_AVX or STBIR_AVX2. + + On Linux, SSE2 and Neon is on by default for 64-bit x64 or ARM64. For 32-bit, + we select x86 SIMD mode by whether you have -msse2, -mavx or -mavx2 enabled + on the command line. For 32-bit ARM, you must pass -mfpu=neon-vfpv4 for both + clang and GCC, but GCC also requires an additional -mfp16-format=ieee to + automatically enable NEON. + + On x86 platforms, you can also define STBIR_FP16C to turn on FP16C instructions + for converting back and forth to half-floats. This is autoselected when we + are using AVX2. Clang and GCC also require the -mf16c switch. ARM always uses + the built-in half float hardware NEON instructions. + + You can also tell us to use multiply-add instructions with STBIR_USE_FMA. + Because x86 doesn't always have fma, we turn it off by default to maintain + determinism across all platforms. If you don't care about non-FMA determinism + and are willing to restrict yourself to more recent x86 CPUs (around the AVX + timeframe), then fma will give you around a 15% speedup. + + You can force off SIMD in all cases by defining STBIR_NO_SIMD. You can turn + off AVX or AVX2 specifically with STBIR_NO_AVX or STBIR_NO_AVX2. AVX is 10% + to 40% faster, and AVX2 is generally another 12%. + + ALPHA CHANNEL + Most of the resizing functions provide the ability to control how the alpha + channel of an image is processed. + + When alpha represents transparency, it is important that when combining + colors with filtering, the pixels should not be treated equally; they + should use a weighted average based on their alpha values. For example, + if a pixel is 1% opaque bright green and another pixel is 99% opaque + black and you average them, the average will be 50% opaque, but the + unweighted average and will be a middling green color, while the weighted + average will be nearly black. This means the unweighted version introduced + green energy that didn't exist in the source image. + + (If you want to know why this makes sense, you can work out the math for + the following: consider what happens if you alpha composite a source image + over a fixed color and then average the output, vs. if you average the + source image pixels and then composite that over the same fixed color. + Only the weighted average produces the same result as the ground truth + composite-then-average result.) + + Therefore, it is in general best to "alpha weight" the pixels when applying + filters to them. This essentially means multiplying the colors by the alpha + values before combining them, and then dividing by the alpha value at the + end. + + The computer graphics industry introduced a technique called "premultiplied + alpha" or "associated alpha" in which image colors are stored in image files + already multiplied by their alpha. This saves some math when compositing, + and also avoids the need to divide by the alpha at the end (which is quite + inefficient). However, while premultiplied alpha is common in the movie CGI + industry, it is not commonplace in other industries like videogames, and most + consumer file formats are generally expected to contain not-premultiplied + colors. For example, Photoshop saves PNG files "unpremultiplied", and web + browsers like Chrome and Firefox expect PNG images to be unpremultiplied. + + Note that there are three possibilities that might describe your image + and resize expectation: + + 1. images are not premultiplied, alpha weighting is desired + 2. images are not premultiplied, alpha weighting is not desired + 3. images are premultiplied + + Both case #2 and case #3 require the exact same math: no alpha weighting + should be applied or removed. Only case 1 requires extra math operations; + the other two cases can be handled identically. + + stb_image_resize expects case #1 by default, applying alpha weighting to + images, expecting the input images to be unpremultiplied. This is what the + COLOR+ALPHA buffer types tell the resizer to do. + + When you use the pixel layouts STBIR_RGBA, STBIR_BGRA, STBIR_ARGB, + STBIR_ABGR, STBIR_RX, or STBIR_XR you are telling us that the pixels are + non-premultiplied. In these cases, the resizer will alpha weight the colors + (effectively creating the premultiplied image), do the filtering, and then + convert back to non-premult on exit. + + When you use the pixel layouts STBIR_RGBA_PM, STBIR_RGBA_PM, STBIR_RGBA_PM, + STBIR_RGBA_PM, STBIR_RX_PM or STBIR_XR_PM, you are telling that the pixels + ARE premultiplied. In this case, the resizer doesn't have to do the + premultipling - it can filter directly on the input. This about twice as + fast as the non-premultiplied case, so it's the right option if your data is + already setup correctly. + + When you use the pixel layout STBIR_4CHANNEL or STBIR_2CHANNEL, you are + telling us that there is no channel that represents transparency; it may be + RGB and some unrelated fourth channel that has been stored in the alpha + channel, but it is actually not alpha. No special processing will be + performed. + + The difference between the generic 4 or 2 channel layouts, and the + specialized _PM versions is with the _PM versions you are telling us that + the data *is* alpha, just don't premultiply it. That's important when + using SRGB pixel formats, we need to know where the alpha is, because + it is converted linearly (rather than with the SRGB converters). + + Because alpha weighting produces the same effect as premultiplying, you + even have the option with non-premultiplied inputs to let the resizer + produce a premultiplied output. Because the intially computed alpha-weighted + output image is effectively premultiplied, this is actually more performant + than the normal path which un-premultiplies the output image as a final step. + + Finally, when converting both in and out of non-premulitplied space (for + example, when using STBIR_RGBA), we go to somewhat heroic measures to + ensure that areas with zero alpha value pixels get something reasonable + in the RGB values. If you don't care about the RGB values of zero alpha + pixels, you can call the stbir_set_non_pm_alpha_speed_over_quality() + function - this runs a premultiplied resize about 25% faster. That said, + when you really care about speed, using premultiplied pixels for both in + and out (STBIR_RGBA_PM, etc) much faster than both of these premultiplied + options. + + PIXEL LAYOUT CONVERSION + The resizer can convert from some pixel layouts to others. When using the + stbir_set_pixel_layouts(), you can, for example, specify STBIR_RGBA + on input, and STBIR_ARGB on output, and it will re-organize the channels + during the resize. Currently, you can only convert between two pixel + layouts with the same number of channels. + + DETERMINISM + We commit to being deterministic (from x64 to ARM to scalar to SIMD, etc). + This requires compiling with fast-math off (using at least /fp:precise). + Also, you must turn off fp-contracting (which turns mult+adds into fmas)! + We attempt to do this with pragmas, but with Clang, you usually want to add + -ffp-contract=off to the command line as well. + + For 32-bit x86, you must use SSE and SSE2 codegen for determinism. That is, + if the scalar x87 unit gets used at all, we immediately lose determinism. + On Microsoft Visual Studio 2008 and earlier, from what we can tell there is + no way to be deterministic in 32-bit x86 (some x87 always leaks in, even + with fp:strict). On 32-bit x86 GCC, determinism requires both -msse2 and + -fpmath=sse. + + Note that we will not be deterministic with float data containing NaNs - + the NaNs will propagate differently on different SIMD and platforms. + + If you turn on STBIR_USE_FMA, then we will be deterministic with other + fma targets, but we will differ from non-fma targets (this is unavoidable, + because a fma isn't simply an add with a mult - it also introduces a + rounding difference compared to non-fma instruction sequences. + + FLOAT PIXEL FORMAT RANGE + Any range of values can be used for the non-alpha float data that you pass + in (0 to 1, -1 to 1, whatever). However, if you are inputting float values + but *outputting* bytes or shorts, you must use a range of 0 to 1 so that we + scale back properly. The alpha channel must also be 0 to 1 for any format + that does premultiplication prior to resizing. + + Note also that with float output, using filters with negative lobes, the + output filtered values might go slightly out of range. You can define + STBIR_FLOAT_LOW_CLAMP and/or STBIR_FLOAT_HIGH_CLAMP to specify the range + to clamp to on output, if that's important. + + MAX/MIN SCALE FACTORS + The input pixel resolutions are in integers, and we do the internal pointer + resolution in size_t sized integers. However, the scale ratio from input + resolution to output resolution is calculated in float form. This means + the effective possible scale ratio is limited to 24 bits (or 16 million + to 1). As you get close to the size of the float resolution (again, 16 + million pixels wide or high), you might start seeing float inaccuracy + issues in general in the pipeline. If you have to do extreme resizes, + you can usually do this is multiple stages (using float intermediate + buffers). + + FLIPPED IMAGES + Stride is just the delta from one scanline to the next. This means you can + use a negative stride to handle inverted images (point to the final + scanline and use a negative stride). You can invert the input or output, + using negative strides. + + DEFAULT FILTERS + For functions which don't provide explicit control over what filters to + use, you can change the compile-time defaults with: + + #define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something + #define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something + + See stbir_filter in the header-file section for the list of filters. + + NEW FILTERS + A number of 1D filter kernels are supplied. For a list of supported + filters, see the stbir_filter enum. You can install your own filters by + using the stbir_set_filter_callbacks function. + + PROGRESS + For interactive use with slow resize operations, you can use the the + scanline callbacks in the extended API. It would have to be a *very* large + image resample to need progress though - we're very fast. + + CEIL and FLOOR + In scalar mode, the only functions we use from math.h are ceilf and floorf, + but if you have your own versions, you can define the STBIR_CEILF(v) and + STBIR_FLOORF(v) macros and we'll use them instead. In SIMD, we just use + our own versions. + + ASSERT + Define STBIR_ASSERT(boolval) to override assert() and not use assert.h + + PORTING FROM VERSION 1 + The API has changed. You can continue to use the old version of stb_image_resize.h, + which is available in the "deprecated/" directory. + + If you're using the old simple-to-use API, porting is straightforward. + (For more advanced APIs, read the documentation.) + + stbir_resize_uint8(): + - call `stbir_resize_uint8_linear`, cast channel count to `stbir_pixel_layout` + + stbir_resize_float(): + - call `stbir_resize_float_linear`, cast channel count to `stbir_pixel_layout` + + stbir_resize_uint8_srgb(): + - function name is unchanged + - cast channel count to `stbir_pixel_layout` + - above is sufficient unless your image has alpha and it's not RGBA/BGRA + - in that case, follow the below instructions for stbir_resize_uint8_srgb_edgemode + + stbir_resize_uint8_srgb_edgemode() + - switch to the "medium complexity" API + - stbir_resize(), very similar API but a few more parameters: + - pixel_layout: cast channel count to `stbir_pixel_layout` + - data_type: STBIR_TYPE_UINT8_SRGB + - edge: unchanged (STBIR_EDGE_WRAP, etc.) + - filter: STBIR_FILTER_DEFAULT + - which channel is alpha is specified in stbir_pixel_layout, see enum for details + + FUTURE TODOS + * For polyphase integral filters, we just memcpy the coeffs to dupe + them, but we should indirect and use the same coeff memory. + * Add pixel layout conversions for sensible different channel counts + (maybe, 1->3/4, 3->4, 4->1, 3->1). + * For SIMD encode and decode scanline routines, do any pre-aligning + for bad input/output buffer alignments and pitch? + * For very wide scanlines, we should we do vertical strips to stay within + L2 cache.

Call stbiw_convert_wchar_to_utf8 to convert + Windows wchar_t filenames to utf8. + +USAGE: + + There are five functions, one for each image file format: + + int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); + int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); + + void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically + + There are also five equivalent functions that use an arbitrary write function. You are + expected to open/close your file-equivalent before and after calling these: + + int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); + + where the callback is: + void stbi_write_func(void *context, void *data, int size); + + You can configure it with these global variables: + int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE + int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression + int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode + + + You can define STBI_WRITE_NO_STDIO to disable the file variant of these + functions, so the library will not use stdio.h at all. However, this will + also disable HDR writing, because it requires stdio for formatted output. + + Each function returns 0 on failure and non-0 on success. + + The functions create an image file defined by the parameters. The image + is a rectangle of pixels stored from left-to-right, top-to-bottom. + Each pixel contains 'comp' channels of data stored interleaved with 8-bits + per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is + monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. + The *data pointer points to the first byte of the top-left-most pixel. + For PNG, "stride_in_bytes" is the distance in bytes from the first byte of + a row of pixels to the first byte of the next row of pixels. + + PNG creates output files with the same number of components as the input. + The BMP format expands Y to RGB in the file format and does not + output alpha. + + PNG supports writing rectangles of data even when the bytes storing rows of + data are not consecutive in memory (e.g. sub-rectangles of a larger image), + by supplying the stride between the beginning of adjacent rows. The other + formats do not. (Thus you cannot write a native-format BMP through the BMP + writer, both because it is in BGR order and because it may have padding + at the end of the line.) + + PNG allows you to set the deflate compression level by setting the global + variable 'stbi_write_png_compression_level' (it defaults to 8). + + HDR expects linear float data. Since the format is always 32-bit rgb(e) + data, alpha (if provided) is discarded, and for monochrome data it is + replicated across all three channels. + + TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed + data, set the global variable 'stbi_write_tga_with_rle' to 0. + + JPEG does ignore alpha channels in input data; quality is between 1 and 100. + Higher quality looks better but results in a bigger image. + JPEG baseline (no JPEG progressive). + +CREDITS: + + + Sean Barrett - PNG/BMP/TGA + Baldur Karlsson - HDR + Jean-Sebastien Guay - TGA monochrome + Tim Kelsey - misc enhancements + Alan Hickman - TGA RLE + Emmanuel Julien - initial file IO callback implementation + Jon Olick - original jo_jpeg.cpp code + Daniel Gibson - integrate JPEG, allow external zlib + Aarni Koskela - allow choosing PNG filter + + bugfixes: + github:Chribba + Guillaume Chereau + github:jry2 + github:romigrou + Sergio Gonzalez + Jonas Karlsson + Filip Wasil + Thatcher Ulrich + github:poppolopoppo + Patrick Boettcher + github:xeekworx + Cap Petschulat + Simon Rodriguez + Ivan Tikhonov + github:ignotion + Adam Schackart + Andrew Kensler + +LICENSE + + See end of file for license information. + +*/ + +#ifndef INCLUDE_STB_IMAGE_WRITE_H +#define INCLUDE_STB_IMAGE_WRITE_H + +#include + +// if STB_IMAGE_WRITE_STATIC causes problems, try defining STBIWDEF to 'inline' or 'static inline' +#ifndef STBIWDEF +#ifdef STB_IMAGE_WRITE_STATIC +#define STBIWDEF static +#else +#ifdef __cplusplus +#define STBIWDEF extern "C" +#else +#define STBIWDEF extern +#endif +#endif +#endif + +#ifndef STB_IMAGE_WRITE_STATIC // C++ forbids static forward declarations +STBIWDEF int stbi_write_tga_with_rle;

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .
