           Summary: mpeg2enc deadlock
           Product: GStreamer
           Version: 0.10.14
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gst...@li...
        ReportedBy: s3...@st...
         QAContact: gst...@li...
     GNOME version: Unspecified
   GNOME milestone: Unspecified


The following command produces a deadlock in the mpeg2enc plugin.  

gst-launch filesrc location="file.mov" ! qtdemux name="demux"  avimux
name="mux" ! filesink location="output.avi" { demux. ! queue ! ffdec_mpeg4 !
videorate ! mpeg2enc ! queue ! mux. }  { demux. ! queue ! decodebin !
audioconvert ! audioresample ! ffenc_mp2 ! queue ! mux. } 

The file I'm using (i.e file.mov) is actually
http://oodt.jpl.nasa.gov/better-web-app.mov.  It is over 300mb.

With debug on level 4:
