Help me understand if my tiny editor JSON is correct

[Fedec96]

I have a DV/HDR10+ source that I want to use to inject both DV & HDR10+ in regular HDR10.
Frames between the two sources are identical, but misaligned.

Inspecting the DV/HDR10+ source's frames, I realized that I had to:

• Remove frames #1-#192
• Duplicate frame #193x16
• Remove frames #155535-#155726

This is the JSON I came up with:

// Zero-based indexes
{
  "remove": ["155534-155725", "0-191"], // Decided to do reverse order to be extra sure
  "duplicate": [
    {
      // Frame #193 (index 192) after the removal step should now be frame #1 (index 0)
      "source": 0,
      "offset": 0,
      "length": 16
    }
  ]
}

With dovi_tool I get this output when I inject the edited RPU.bin file:

Warning: mismatched lengths. video 155402, RPU 155358

Which is OK because I do want the extra frames at the end to be duplicated.

But when I inject the HDR10+ JSON edited with the same configuration with hdr10plus_tool I get a different number:

Warning: mismatched lengths. video 155402, HDR10+ JSON 155166

I expected the numbers to be the same, but I'm clearly missing somthing.

I'm here to ask essentially:

• Whether my understanding on the editor part is correct (and thus, my JSON file makes sense)
• Whether the numbers in the mismatch warning are expected (or not), and why

TIA!

You might be running into #107

You might be running into #107

I see. I guess I'll wait for a new release! In case I re-inject the metadata, will it overwrite the existing information or do I have to start over with the "vanilla" video stream?

The alternative is doing the remove/duplicate in multiple steps instead of a single edit.

Worked like a charm. Thank you for what you do.
