Comment (by Balling):

 Re mailing list:

 There is a chance we will move to XYZ media soon, since it is the only
 level left after PQ 12 bit 8K video. So better to hardcode it, as it will
 be faster and optimised by compilers better, maybe even -march=native and
 x86_64-v3 will work cute, see this: https://github.com/zhongfly/mpv-
 winbuild/releases/tag/2024-12-21-d827019 (ffmpeg-x86_64-v3-git-
 095f8038f.7z, nice)
