Original commit message from CVS:
* ext/ffmpeg/gstffmpegcfg.c:
FLV is in fact h263 and can take the same parameters as other mpeg
derivatives.
* ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_codecid_to_caps),
(gst_ffmpeg_caps_with_codecid):
Add pixel format to video/x-dv,systemstream=False
* ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_class_init),
(gst_ffmpegenc_init):
Use EPZS (Enhanced Predictive Zonal Search) as the default motion
estimation method, since it's the best quality to speed compromise.
