I figured I'd take a look at this as I'll be doing a fair amount of camera work over the next couple of months. Right off the bat there'll need to be some reconfig as the current config only pulls back a single track from the MediaStream, the video one. I'll be using a Logitech C920 for testing. I'll be happy to create a GitHub public repo and commit regularly for whomever is interested. :) |

@webtop we are open for PRs, we would love your contribution to this project. |

April 23, 2020 Hello: Is anyone still looking at this thread? I'm attempting to make Balena-Cam operate under a better framerate. The existing one is very very slow. ?? Brian Wayne |
|
I'm still poking at it. I have the refresh rate much better, but ran into an issue that was a bug in Python 3.5, which is what the project Dockerfile pulls from. The issue has been resolve now, but the Python version needs increasing. First of all, for audio, you need to get rid of using OpenCV, as that is for video only. I'm using PyAV (already used partially), but that is how the bug was found. @mbalamat Is there a version of fincm3 image that uses a newer version of Python? I'll post my changes so far to my GitHub repo, for anyone interested. Audio is almost there now. |
|
@hinzendo27 If you'd like to collaborate and list/fix changes together, let me know. That way we aren't both doing the same work. :) |

Hello:
The issue with regard to audio, is not what I'm currently working. I'm not
that up so speed on dockers and all of that. When I "run" the camera
RasPi, the framerate is very very slow. There's no big monster rush right
now. If one is drawing on a graph board, or something, one would like to
use gestures to help better communicate a point. Currently, the
framerate is too slow for that, but as I was saying it's not a big monster
rush.
If anyone has time, whenever they have the time, any new info would help.

If you need help, let me know. With regard to pulling a "docker" file out
of a RasPi, and then parsing through the python files and all that, I'm
very much in the dark on all of that. I'm base level, in regard to python,
and base level with OpenCV. But, I have no idea how to reconstruct a
docker file or any of that.
Any help you would need, I can try to assist somewhat, I'm mostly in the
dark here.

Hi guys great to hear that you like the project and want to contribute! @webtop what python version do you need? I can try bumping the python version for you though the only blocker that I had and didn't bump the version in past was the library dependencies. @hinzendo27 awesome idea about the frame rate increase can you explain to me how do you plan on increasing the frame rate? |

Marios:
Thank you for the email. My recent message was addressing that issue. I'd
like to spell out some big long series of steps about improving framerate,
but I don't know how to unassemble a Docker Container, or any of the files
so associated. The other guy is Paul, I mentioned to him how in the dark I
am here. Any info would help.

@mbalamat Anything >= 3.5.8 should be good as that's when the buf got fixed. |
|
@hinzendo27 to start tinkering with the code, you can try run balena-cam locally on your computer. Just install python 3. In our dockerfile there are the dependencies you need. See the pip install part. @pallsopp whenever I get some time I'll try myself to use another version. For now can you try changing the base image from what we currently have to something from here https://hub.docker.com/r/balenalib/raspberrypi3-python and regarding the tags something from here https://hub.docker.com/r/balenalib/raspberrypi3-python/tags?page=1&name=3.7? |

There is like a 90 second delay for the video (one has to wait that long).
I don't know if there's an IDE for these Docker Files or whatever ( I know
Python has associated IDEs -- Thonny on RasPi being one of them). I hope
these videos maintain something of a private nature.

The technology behind all of this is called WebRTC. You can check it out on webrtc.org |

Paul:
The directory structure of a provisioning system on one's hard drive is a
bit of a head scratcher. It's confusing to make out what's being
provisioned to the RasPi, and how. I'm updating a resume too, so I have to
steer away from this for a time. I'll get back in a few days.

The WebRTC APIs are JavaScript based, with bindings for Python. That delay
at the start is partly due to the technology handshaking between the
front-end and back-end. That's where the security comes into it.
There are some great videos on YouTube also concerning WebRTC, that are
definitely worth a look.

No problem.Just to be clear, in case it wasn't obvious, webtop and pallsopp are the same person....me. This is my work account, and webtop is my personal account. During the day I'm usually logged in under my work account, and in the evening, my personal account. Sometimes I forget to switch :) |

@hinzendo27 The basics of a Dockerfile contain everything that's needed to build a system-on-the-fly. This really isn't the place for a detailed explanation, but I thought I'd fill you in on the most important parts: Hope that helps. |

Thanks for taking the time to plow through some of the detail. We're all
busy.
If one "populates" a windows pc with 1) a DOS "lobe" needed to force the
balena cli into local operation, and 2) a "lobe" which contains the
balena-cam provisioning tree, that all makes sense.
Perhaps I need to approach the general balena forum to "disect" what's
going on in that entire balena-cam "lobe". Only then can I start to
upgrade potential framerate issues.
Thanks for taking the time.

The FROM parts pulls a system image that someone has built and contains
all the software you need to run a project. That system image contains your
system files, folders, and libraries: almost a complete linux system, but
just enough to make everything work.
The RUN parts are your command as if you were logged into the system: for
example apt-get install commands to install the libraries you need for the
project to work.
Once everything is in place, you COPY your code folder to a path on the
system, and set that as your working directory.
This really isn't the place for a detailed explanation, but I thought I'd
fill you in on the most important parts:
FROM an image you get your system
RUN your command to tailor the system to your needs
COPY your code to a place you can run it on the system
Hope that helps.

Do you know of a way to ssh into a balena Raspi from a raspbian Raspi? I'm
using a wifi hotspot. I'm not sure how to ssh over wireless, especially if
it's with someone's hotspot. When I'm using ethernet, ssh is very easy,
but the wireless seems to throw a wrench into the works. I need to be able
to quickly post photos to a subordinate type directory. I'm having trouble
performing ssh over wifi. Maybe you're too busy, I just thought I'd ask.
Posting photos by a provision, is a non-issue -- very easy. SSH over
wireless, not so much.

If your raspis are running containers that are on the cloud, you should be able to use balena ssh. If you are using ssh from the commandline, you might need to change the port to 22222, which is the ssh port to a local instance. Give that a try, or let me know more info about how the containers are. Thx |

Right now, funds are a little tight. It may be asking quite a bit, but I'm
trying to use the Raspbian system on one of the pis, and ssh into the
balena OS on another. There are like 4 raspberry pis. Using the hotspot,
I'm trying to make it work. I don't have a huge background with firewalls
or any such thing.
Using ssh across multiple platforms would help, but I'm not sure "sshing"
across them would fly (especially with a WiFi hotspot in the middle). If I
put a photo onto the Raspbian Pi, then ssh into the balena pi, I could
transfer photos. Just trying to save money. I don't know how to transfer
files from like a usb drive or whatever into the balena pi. ?? I don't
have all of my networking stuff right now, I stored it in a friend's for a
while.
The Picture Server I'm trying to set up, is a Pi Zero W, so, an ethernet
connection will be a problem.
This is kind of a head scratcher. Maybe I'm making it more complicated
than it has to be.

What does your push command look like? |

April 30, 2020
Hello:
Immediately following the push command all of the provisioning commands
appear on the windows screen (seems to take like 4 to 9 minutes, or so).
Then at the very end of the provision sequence there is a statement about
"HTTP code 404", and the whole process dumps -- "not deploying release".
In all of the "sea of red ink" that shows up at that point, it says "remote
build failed. It says something about using "export DEBUG" -- don't know
what they're driving at.

Using export debug allows for a verbose output, so you get a lot more detail.
Getting a 404 means that a web request failed, specifically that an endpoint for one of the requests could not be found.
From the command line, type DEBUG=1
then hit enter and type your push command again. You should then get a verbose output, which you can post and I’ll take a look at it
It ain't easy being green! Please recycle.
