Additional information

Initially I thought this was an issue with nouveau and opened mesa/mesa#3924. However, it turns out that MPlayer is able to play the video correctly using VDPAU:

VDPAU_DRIVER=nouveau mplayer -vo vdpau -vc ffodivxvdpau https://archive.org/download/BigBuckBunny_328/BigBuckBunny.avi

Which suggests this is an issue or incompatibility with mpv, so I'm reporting it here.

Thanks, Kevin

For reference, I'm also able to reproduce the issue in XFCE 4.16, so it's not Wayland-specific.

In the future, provide truncated samples so we don't have to download several hundred megabytes to test an issue.

Anyway, I have an old nvidia card that I can use to test this but it'll take a bit of time.
