Mmmm.
So far I have just tried to install ffmpeg 8.1 from Packman on
Tumbleweed to see if they have enabled JEPE-XS support.
But unhappily there is currently several dependency issues so ffmpeg 8.1
could not be launched.
I think you also need this patch for ffmpeg 8.1:
I tricked build to ignore asm primitives, and one frame at 1080p come out at 6 megabytes (444p12, reencode from prores mov)
