  GStreamer | gst-ffmpeg | 0.10.32

           Summary: Invalid Data Stream Error from gst-ffmpeg for CDG file
    Classification: Platform
           Product: GStreamer
           Version: 0.10.32
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: john.carr at unrouted.co.uk
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


Using ggst-ffmpeg 0.10.11 and gst 0.10.32.

I am using a sample from:

http://www.powerkaraoke.com/download/NobodyKnowsYou.cdg

Totem is unable to open it.

I attempted to write a gst-launch pipeline and that yielded an Internal Data
Error.

I used:

gst-launch-0.10 --gst-debug ffmpeg:5 filesrc location=/tmp/NobodyKnowsYou.cdg !
ffdemux_cdg ! ffdec_cdgraphics ! ximagesink

The error seems to be coming from gst_ffmpegdata_peek which claims it is
pulling 21600 bytes then fails with "Got -3 (unexpected) return result 0".
