Description Bálint Magyar 2009-01-29 21:36:32 UTC 
Please describe the problem:
720p MPEG2 part4 footage taken directly from my Samsung HMX10C plays back slowly inside PiTiVi, while Totem (also using gstreamer) plays them back decently with a few framedrops here and there. PiTiVi doesn't skip a single frame, rather it plays like it's in slow motion. Problem occurs regardless of framerate set in Project Settings.

Sound is not affected.

Steps to reproduce:
1. Import a 720p 50fps MPEG2 part4-enclosed H.264-encoded clip.
2. Play said clip either as a preview or from the timeline.


Actual results:
Video playback seems to play in slow-motion, audio doesn't seem affected.

Expected results:
Video should playback at normal speed to keep up with audio, even if frames need to be skipped.

Does this happen every time?
Yes.

Indeed, we have qos disabled on videosinks for a couple of years now. The problem way to re-enable it depends on bug #398453 to be fixed.

    plumber: enable QoS in sinks now that gnonlin handles QoS events.
