           Summary: ffdec_h264 crashes when decoding a certain video
                    stream
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.10
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

I have a mkv format video file. And each time I use the pipeline
gst-launch filesrc location=xxx.mkv ! matroskademux ! ffdec_h264 ! ...
to decode that file, it first runs for quite a long time, generating correct
output (I can link the output to xvimagesink, or pass it for further encoding),
but after a while an SIGABRT is signaled, and the program aborts.

That file is the only one I have found to cause the problem. I'm not sure
whether the file is broken, but when I use other media players to play that
file I don't see any problem.

gstreamer version is 0.10.28,
the matroska plugin is 0.10.21,
gst-ffmpeg is 0.10.10.

The gdb backtrace is posted as attachments. I tried to post a coredump, but it
seems to be too big (nearly 80 MBs).
