Summary of the bug:
How to reproduce:
{{{
% ffmpeg -ss 00:30 -i test.mp4 -vf
zscale='primaries=bt709:transfer=bt709:matrix=bt709',format='yuv420p'
-frames 1 out.png
ffmpeg commit b410b14
built on Xcode 12.3
}}}
Reproduced on both FFmpeg 4.3 and FFmpeg git-master
I don't know if this is a FFmpeg issue or a zimg issue, I couldn't
reproduce it in zimg test-app, but I don' have access to a M1 Mac anymore
so I can't do any further testing.
