           Summary: [avidemux] avidemux not recognizing certain uncompressed
                    RGB fourcc's
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Macintosh
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: nick at haddads.net

     GNOME version: Unspecified
   GNOME milestone: Unspecified


In AVI files there are certain fourcc codes that have been traditionally taken
to mean uncompressed RGB (i.e. "video/x-raw-rgb").  These fourcc codes are:

'DIB '
'RAW ' 
'RGB ' 
0x000000

Unfortunately the gst_riff_create_video_caps only currently recognizes 'DIB '
as an uncompressed RGB. 

This causes certain uncompressed AVI files (see attached example.avi) to no
render properly in gstreamer using the avidemux element in gst-plugins-good.

Steps to reproduce:
1) Download attached example.avi to /tmp
2) Run the following:
 gst-launch playbin uri=file:///tmp/example.avi

Expected results:
File would render properly

Actual results:
File does not render and returns a video/x-avi-unknown codec error.
