Just so you know, mplayer2 is dead and will not be part of the next
release of Debian and if the bug was in mplayer2 itself it would likely
not be fixed. Since it affects smplayer as well, it's probably a bug in
libav or some other part of the graphics stack instead.

From the logs, clearly Xorg has died somehow. It would be useful to know
how it died. Is there anything earlier in the syslog? The relevant Xorg
log in /var/log might also be useful.

That would be useful.

Can you try playing the file with avplay from libav-tools? It would also
be useful to know if the file worked with a recent version of ffmpeg. To
do that you would have to install ffmpeg from jessie-backports and play
the file with ffplay.

Thanks,
