Original commit message from CVS: * ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_get_palette), (gst_ffmpeg_set_palette), (gst_ffmpeg_codecid_to_caps), (gst_ffmpeg_pixfmt_to_caps), (gst_ffmpeg_caps_to_smpfmt), (gst_ffmpeg_caps_to_pixfmt), (gst_ffmpeg_caps_with_codectype), (gst_ffmpeg_caps_with_codecid), (gst_ffmpeg_caps_to_codecid): * ext/ffmpeg/gstffmpegcodecmap.h: Change some function names to reflect that they don't really _return_ something, but rather _use_ something to fill a AVCodecContext. s/to/with/. Restructure the extradata handling, it's now not picking up the type from the caps but rather using the type as provided in the function. This is a lot cleaner. Implement MS RLE palette pickup. * ext/ffmpeg/gstffmpegcolorspace.c: (gst_ffmpegcsp_pad_link): * ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_connect): Sync with the above function name changes. * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_close), (gst_ffmpegdec_open), (gst_ffmpegdec_connect), (gst_ffmpegdec_chain), (gst_ffmpegdec_change_state): Add some hacks to convert palette-based raw image formats to RGBA32. Ugly, but I don't know how else to handle palette-based RGB, since img_convert() (and thus ffcolorspace) doesn't accept a palette as argument.
