Description Tim-Philipp Müller 2007-08-08 11:30:56 UTC
This sometimes doesn't preroll for me with CVS, neither with decodebin nor with decodebin2:

$ USE_DECODEBIN2=1 gst-launch-0.10 playbin uri=

Don't think we ever had problems with quicktime trailers in previous releases.

Attaching debug log.

FWIW, this appears to be reproducable for other people with gutsy packages too:
<Zapek> __tim: stuck at 88 here. gutsy

Debug log can be found here (too large for bugzilla):

This seems to work fine for me with decodebin now, but still not with decodebin2.
Comment 3 Tim-Philipp Müller 2007-09-11 11:30:02 UTC
Works for me now with this:

        * gst/playback/gstplaybasebin.c:
          Increase upper limit for audio queue a bit; fixes preroll problem
          with playbin and decodebin2 when playing a quicktime trailer with
          multichannel audio via http (#464666).
