Looks like it's a gallium thing - I run git mesa and there have been a

Ok: in the absence of any evidence that the problem is on the mplayer
side, I will ignore this?

I am not really qualified to say whether it's mplayer or not - as per my other post mpv doesn't seem to have any issues.

I also tried anamorphic video.  There is something a bit strange going
on because I got the behaviour you described with extra black bars when
playing in a window, but it did the right thing once it went fullscreen.
  Maybe it's just that the window is made initially with the wrong
aspect ratio?

Yes, I tried with a different 16/9 sample 544x576 and that is the size
of the initial window.


Yep, it wasn't handling the reconfigure properly to get a correct output
window (vo config gets called with display size = decode size, then
again a bit later with the correct display size).  Fixed, new patch
attached.

I crash/assert instantly with the new patch in the case of anamorphic.

I get different traces depending on the source vid.
