Original commit message from CVS: * ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_codecid_to_caps): * ext/ffmpeg/gstffmpegcodecmap.h: * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_chain), (gst_ffmpegdec_register): * ext/ffmpeg/gstffmpegdemux.c: (gst_ffmpegdemux_add), (gst_ffmpegdemux_register): * ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_connect), (gst_ffmpegenc_register): * ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_register): Add encode property to codec mapper, so we can get better-fitting caps. Also use this everywhere. ;). Lastly, add some new codecIDs to our list of recognized ones.
