API changes, most recent first:
2014-04-xx - xxxxxxx - lavc 55.50.3 - avcodec.h
Deprecate CODEC_FLAG_MV0. It is replaced by the flag "mv0" in the
"mpv_flags" private option of the mpegvideo encoders.
2014-04-xx - xxxxxxx - lavc 55.50.2 - avcodec.h
Deprecate CODEC_FLAG_GMC. It is replaced by the "gmc" private option of the
libxvid encoder.
