           Summary: mpegdemux does not emit no-more-pads signal
           Product: GStreamer
           Version: 0.10.6
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: gst-plugins-ugly
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

     GNOME version: Unspecified
   GNOME milestone: Unspecified


Please describe the problem:
The mpegdemux plug-in does not invoke a registered callback for "no-more-pads"
once the video and audio source pads have been created. My test case is playing
an MPEG-1 video file.

Steps to reproduce:
I set up the following chain from a program:

gst-launch gnomevfssrc location=file:///home/zombie/download/mpeg/tripping.mpg
! mpegdemux name=demux  demux.audio_00 ! fakesink   demux.video_00 ! queue !
mpeg2dec ! ffmpegcolorspace ! videoscale ! xvimagesink


Actual results:


Expected results:


Does this happen every time?


Other information:
qtdemux does do this fine. I tried to look in the sources (current svn) and I
can see this being emitted for dvddemux in the same directory. It's not clear
to me when the signal should be emitted though, as there are also private
stream sources. How does one know when there will really be no more pads
created...?
