Description Sven Arvidsson 2008-02-05 21:52:23 UTC 
The Ogg Theora videos of the talks at LCA seems to have some problems with GStreamer. 

The video either isn't played at full speed, or possibly some frames are missing. Audio on the other hand is fine. Also, skipping forward or backward isn't instantaneous, there's a small delay where the video freezes before playback begins again.

Other Theora videos I have play fine in GStreamer, and the LCA videos do work with MPlayer.

Comment 1 Wim Taymans 2008-02-06 11:51:13 UTC 
The seeking is normal, we don't seek to keyframes so it might take a while before video can continue after a seek.

The timestamp interpolation seems to have regressed in 0.10.17 :(

Fixed with:

    * ext/theora/theoradec.c: (_theora_granule_frame),
    (_inc_granulepos):
      Increment granulepos for new-bitstream versions appropriately.
      Fixes #514623.
