[Bug 780007] Re: [Natty] Stuttering video playback


** Description changed:

  Binary package hint: compiz
  High frame rate/bitrate videos are stuttering badly with compiz (Unity
  and Ubuntu Classic with effects) in VLC, Mplayer and Totem. For example:
  if I enable yadif (double framerate) deinterlacing on a DVD Video or
  watching 50/60fps progressive SD materials. In full screen mode the
  stuttering is getting worse (~10fps).  Mplayer doesn't show AV sync
  problems or dropped frames and the CPU usage is normal (see attached
  screenshot).  All of these videos are running smoothly under Unity 2D
  and Ubuntu Classic without effects.  I tried different video outputs and
  different ccsm setting combinations including sync to vblank, the
  unredirect fullscreen window option and manually adjusting the refresh
  rate, but the problem still exists.
  It looks like compiz doesn't sync properly. Under Unity and Unity 2D
  glxgears shows 60fps, but in Unity the animation is stuttering even if
  nothing else is running. Also while playing these videos in full screen
- glxgears drops to 45-50fps, but only under compiz. I have a desktop PC
- with an NVIDIA G210 VGA which is much faster than the ATI X200M and this
- video stuttering exists there too.
+ glxgears drops to 45-50fps, but only under compiz. I turned off
+ Animations and Fading windows in ccsm, but it didn't help. Looks like
+ the X200M can't handle compiz with reasonable performance.
+ (I have a desktop PC with an NVIDIA G210 VGA which is much faster than
+ the ATI X200M and this video stuttering exists there too.) --> This was
+ a VDPAU problem because when I turned off hardware acceleration the sync
+ problem gone.
