ffmpeg @4.4.x videotoolbox invalid DTS

[Alexivia (Alexandre Vieira)]

When attempting to use either h264_videotoolbox or hevc_videotoolbox on an M1 Pro MacBook with Monterey, ffmpeg 4.4.x fails with a message "DTS is invalid". If using the software counterparts (libxxxx) the encoding works.

This is inline with ​https://githubmemory.com/repo/tanersener/ffmpeg-kit/issues/178.

By manually installing an older version of the ffmpeg port, like in commit f7789e13, encoding works fine.

Sorry for the delay, didn't notice this ticket when it was first opened.

Patch added to ffmpeg-devel. Once we've confirmed that all is well across-the-board, I'll apply it to ffmpeg as well.

[mascguy (Christopher Nielsen)]

Evan/Dean/Peter, while I wouldn't expect this patch to cause any issues for PPC - at least in principle - it would be great to verify that, prior to adding this to ffmpeg.

Are any of you folks presently utilizing ffmpeg-devel on your PPC systems? If not, is there any interest in testing this latest change?

My PPC machine is currently blocked on #64212

I can’t really say as I don’t own a PPC Mac only Intel/Apple Silicon systems.
