           Summary: H264 Internal data flow error when linking with
                    matroskamux
    Classification: Platform
           Product: GStreamer
           Version: 1.0.10
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Pipeline fails when trying to stream H264 from an Axis camera, mux, and save to
file.

The problem can be created using gst-launch and the pipeline:
  rtspsrc location="rtsp://192...." ! rtph264depay ! h264parse ! matroskamux !
fakesink

It appears the h264parse element is unable to fully link with matroskamux.
After the caps have successfully negotiated, the pipeline stops with the error
: 'Internal data flow error. Reason not-negotiated (-4).' 

It is noted that the pipeline:
 uridecodebin ! x264enc ! h264parse ! matroskamux ! fakesink
functions properly. This led me to believe that this problem may be be related
to the following reported bug:
 - https://bugzilla.gnome.org/show_bug.cgi?id=646327

However, the latest code for h264parse (which includes the patch for the
reported bug) was compiled and tested, but the issue is still present.
