           Summary: lame plugin hangs
           Product: GStreamer
           Version: 0.10.3
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-ugly
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: bugzilla at lwillis.plus.com

     GNOME version: Unspecified
   GNOME milestone: Unspecified


The following pipeline correctly separates (& plays) the audio track from an
AVI file:

$ gst-launch-0.10 filesrc location="ben.avi" ! decodebin ! osssink

If, instead of playing the audio I try to convert it to an MP3 using the lame
plugin using the following pipeline, the command never finishes and no output
file is created.

$ gst-launch-0.10 filesrc location="ben.avi" ! decodebin ! lame ! filesink
location="foo.mp3"

The only output is 

"
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
"

Running with -v gives the following:

$ gst-launch-0.10 -v filesrc location="ben.avi" ! decodebin ! lame ! filesink
location="foo.mp3"
Setting pipeline to PAUSED ...
/pipeline0/decodebin0/typefind.src: caps = video/x-msvideo
Pipeline is PREROLLING ...
/pipeline0/decodebin0/queue0.sink: caps = image/jpeg,
framerate=(fraction)500000/33333, width=(int)320, height=(int)240
/pipeline0/decodebin0/jpegdec0.sink: caps = image/jpeg,
framerate=(fraction)500000/33333, width=(int)320, height=(int)240
/pipeline0/decodebin0/jpegdec0.src: caps = video/x-raw-yuv,
format=(fourcc)I420, width=(int)320, height=(int)240,
framerate=(fraction)500000/33333

Versions below:
ii  libgstreamer0.10-0                     0.10.4-1ubuntu1                     
 Core GStreamer libraries and elements
ii  gstreamer0.10-plugins-ugly             0.10.3-0ubuntu1                     
 GStreamer plugins from the "ugly" set
ii  gstreamer0.10-plugins-base             0.10.5-0ubuntu3                     
 GStreamer plugins from the "base" set

I'm not 100% convinced that this is a valid pipeline - but it seems that it
should be, and cursory enquiries on #gstreamer suggested it should work.
