Created attachment 88194 [details] gdb output for 'mpv -vo xv sintel.mkv' avprobe output: Stream #0.0(eng): Video: h264 (High 4:4:4 Predictive), yuv444p10le, 4096x1744 [PAR 1:1 DAR 256:109], 24 fps, 24 tbr, 1k tbn, 48 tbc (default) When trying to play 4K video with Xv video outputs mpv, mplayer2 and vlc segfault. https://github.com/mpv-player/mpv/issues/320 "the segfault is because the XvShmCreateImage API function returns a smaller image than requested, which, if I read the manpage right, is not allowed." My software: Gentoo Linux amd64 stable, kernel 3.9.9-hardened, mesa-9.1.6, xf86-video-nouveau-1.0.9, libXv-1.0.10, libdrm-2.4.46, xorg-server-1.14.3, libav-9.10 Hardware: 01:00.0 VGA compatible controller: NVIDIA Corporation G86M [GeForce 8400M GS] (rev a1) Used this file for testing: http://rutracker.org/forum/viewtopic.php?t=4131293 Can upload sample if required. P.S. With radeon r600g this file works fine, is any 4K playable with nouveau now?
Created attachment 88195 [details] sample.mkv Added sample.
Created attachment 105069 [details] [review] patch Untested patch to get rid of the wrong size check. Unfortunately at query time we aren't passed the port pointer by the DDX API. Instead check it at PutImage time and return a BadMatch if you do something bad.
