Hello, I have a performance/sync problem when playing raw YUV or DV video. I've invested many days now and can't find a solution. The playback is fine with gstreamer alone (with glimagesink and VBLANK by the graphics driver), but in clutter it's stuttering.
The real strange thing is that it sometimes plays without any problem, and sometimes not. I've made this experience on different systems. These systems always have < 30% CPU load and 2-4 cores. This behaviour is also reproduceable with the example video-player from clutter-gst so the problem isn't in my code. Some runs are ok, some not. Could this be a sync problem between the two frameworks - gstreamer with it's framerate - clutter with the VBLANK (which is turend on)? Clutter reports FPS between 25-26 - does this mean it's a bit too fast or is this measurement just not so exact? The source (in this case a DV video in PAL size) was once decoded to YUY2 (and then to I420) but also to RGB - with no difference. Any thoughts?
