GStreamer | gstreamer (core) | Ver: 0.8.5

           Summary: gst-launch-ext fails with "pushing data on non-
                    negotiated pad demux:video_00, not allowed."
           Product: GStreamer
           Version: 0.8.5
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)

Trying to play video files using gst-launch-ext fails.  The following error is
written repeatedly:

(process:6132): GStreamer-WARNING **: pushing data on non-negotiated pad
demux:video_00, not allowed.

(process:6132): GStreamer-WARNING **: pushing data on non-negotiated pad
demux:audio_00, not allowed.

This occurs for QuickTime and ASF video files that use various codecs.  Though
gst-launch-ext fails, totem will play the files when using the gstreamer backend.

Previous versions of gstreamer did not have this problem.  I have played these
files using gst-launch-ext in the past.

Here is one example of a failed pipeline that gst-launch-ext creates:

gst-launch-0.8 filesrc location="foo.asf" ! asfdemux name=demux ! { queue !
spider ! ffmpegcolorspace ! xvimagesink } { demux. ! queue ! spider ! osssink }
