           Summary: Dead lock when transcoding a file to H264/AAC
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: don't know
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: gdesmott at gnome.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


- GStreamer master (all components)
- Grab http://agot.be/~lachambre/bug/20101223-1_bb_pl.wmv
- Try transcoding it using: gst-launch-1.0 filesrc
location=20101223-1_bb_pl.wmv ! decodebin name=demux ! queue ! videoconvert !
videoparse ! x264enc ! mp4mux name=mux ! filesink location=gst.mp4 demux. !
queue ! audioconvert ! audioresample ! audioparse ! faac ! mux.
- After a while the pipeline is stuck in a dead lock; see the log
http://agot.be/~lachambre/bug/gst-transcode-deadlock.log.gz


Looks like there is something wrong with the wmv file. I tried transcoding it
using ffmpeg directly and it didn't manage to transcode the full file. But at
least gst shouldn't get stuck and stop as well.
