            Bug ID: 787044
           Summary: Unable to decode h.264 from RTSP server
    Classification: Platform
           Product: GStreamer
           Version: 1.10.4
                OS: Mac OS
            Status: NEW
          Severity: major

     GNOME version: ---

I've got an IPTV device which appears to work just fine with VLC and other
RTSP-capable software.  However within the playbin (as well as other pipelines
I've tried) it appears h264parse is unable to handle the datastream.  I see the
following from the gstreamer debug output:

gst-launch-1.0 playbin uri=rtsp://192.168.1.168:554/hdmi --gst-debug=3
