Ronald S. Bultje 2a754af351 ext/ffmpeg/: fix typo in RGB masks, and move back to "old" colorspace capsnego code until whoever wrote this new crap... 
Original commit message from CVS:
2003-12-24  Ronald Bultje  <rbultje@ronald.bitfreak.net>

* ext/ffmpeg/gstffmpegcodecmap.c:
* ext/ffmpeg/gstffmpegcolorspace.c: (gst_ffmpegcsp_getcaps),
(gst_ffmpegcsp_srcconnect_func), (gst_ffmpegcsp_sinkconnect),
(gst_ffmpegcsp_srcconnect), (gst_ffmpegcsp_get_type),
(gst_ffmpegcsp_base_init), (gst_ffmpegcsp_class_init),
(gst_ffmpegcsp_init), (gst_ffmpegcsp_chain),
(gst_ffmpegcsp_change_state), (gst_ffmpegcsp_set_property),
(gst_ffmpegcsp_get_property), (gst_ffmpegcsp_register):
fix typo in RGB masks, and move back to "old" colorspace
capsnego code until whoever wrote this new crap has actually
tested it so that it works.
And yes, this works, keep it that way please.
