  GStreamer | gst-plugins-base | Ver: HEAD CVS
           Summary: theoraparse doesn't work at all (throws criticals and
                    asserts)
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: ogg.k.ogg.k at googlemail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified

Please describe the problem:
using theoraparse (eg, with the first example pipeline mentioned in
theoarparse.c) fails. It throws criticals and asserts before stopping
the pipeline. This happens with all the Theora videos I've tried.

Steps to reproduce:
1. Build/install theoraparse
2. Run any pipeline using it (eg, filesrc ! oggdemux ! theoraparse ! fakesink)
3. Weep as it complains loudly

Actual results:
See sample command line and output below.

Expected results:
I'd expect the pipeline to go to playing, and finish properly.

Does this happen every time?
Yes

Other information:
I believe the theoraparse element is broken. I think I'm using it correctly
as the same usage works fine with, eg, vorbisparse. Here's the output with
a Theora video which oggz validate (a validation tool for Ogg streams) sees
as compliant. Note the criticals from theoraparse, the asserts, and the odd
fact that several different outputs can happen (some kind of race ?)
This (or similar) happens with all the Theora videos I've tried, but in case
you want this particular one, it's available from http://www.fsf.org/fry/.

I have a patch for part of this (BOS flag not being set, so the BOS packet
is being rejected by libtheora). I do not have a patch for the rest of the
problem though, as it fails a bit later with the patch in.
