1921 av_lockmgr_register() can be used to register a callback function
1922 that lavc (and in the future, libraries that depend on lavc) can use
1923 to implement mutexes. The application should provide a callback function
227d1b98

1924 that implements the AV_LOCK_* operations described in avcodec.h.
1925 When the lock manager is registered, FFmpeg is guaranteed to behave
1926 correctly in a multi-threaded application.

1936 The old decoding functions are deprecated, all new code should use the
1937 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1938 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1939 argument instead of a const uint8_t *buf / int buf_size pair.

1949 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

1951 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1952 PIX_FMT_BGR32_1 are now macros.
1953 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
