Description Benjamin Otte (Company) 2003-04-27 01:22:54 UTC 
Try this:
gst-launch -v { filesrc location=music.ogg ! queue } ! vorbisfile ! fakesink
Compare to:
gst-launch -v filesrc location=music.ogg ! vorbisfile ! fakesink

Notice:
The timestamps output are totally different. In the first case they are
wrong (too close).


This breaks ALSA as it syncs to timestamps and I can't hear oggs in net-rb
anymore.

This appears to be some kind of race condition.  Adding the following
line causes the launch line to work... sometimes.

Comment 2 Benjamin Otte (Company) 2003-05-01 12:46:29 UTC 
I've been told by Wim that this is caused by the queue not doing
correct queries, because it doesn't include the currently queued
buffers when figuring this out.
And the timestamp calculations depends on this.

Is this still a problem with oggdemux?
Comment 4 David Schleef 2004-04-21 00:51:57 UTC 
vorbisfile was removed.  Closing.
