Patch for uncompressed RGB support (2.00 KB, patch)
2008-10-30 15:58 UTC, Nick Haddad 		committed Details | Review

Description Nick Haddad 2008-10-30 15:57:47 UTC 
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.
