Well, according to the logs you're using "mpv", which, along with
mplayer2, is not mplayer. I recommend mplayer. Not sure what the sdl
video output does TBH, I've never used it -- perhaps mpv still manages
to use GL for that? xv and vdpau are ones to use. [ In order to use
VDPAU for decoding, you of course have to follow the instructions at
https://nouveau.freedesktop.org/wiki/VideoAcceleration/#firmware ]

things in multiple threads kills nouveau, and mpv does precisely that.
