I upgraded my Ubuntu 19.10 laptop to 20.04 LTS and now mpv is unable to play any video. I've tried it with files that played fine on 19.10. All I get is
$ mpv http://intranet-host.example.com/somevideo.avi
(+) Video --vid=1 (mpeg4 624x480 23.976fps)
(+) Audio --aid=1 (mp3 2ch 44100Hz)
[vo/gpu/wayland] GNOME's wayland compositor is known to have many serious issues with mpv. Switch to GNOME's xorg session for the best experience.
AO: [pulse] 44100Hz stereo 2ch float
VO: [gpu] 624x480 yuv420p

I'm using an Ubuntu on Wayland session.
