I noticed that our MPV cannot play back AV1 videos in real-time on my
Thinkpad x230 laptop.
MPV gets AV1 playback support from FFmpeg. Our FFmpeg package includes
both the libaom and dav1d AV1 decoders. I think that MPV is using
libaom, and that is too slow.
I rebuilt FFmpeg without libaom, and MPV can play my AV1 test file fine
now, using dav1d.
I wonder, is there a way to change the preference?
