f988ce6c
1896 av_lockmgr_register() can be used to register a callback function
1897 that lavc (and in the future, libraries that depend on lavc) can use
1898 to implement mutexes. The application should provide a callback function
227d1b98
DB
1899 that implements the AV_LOCK_* operations described in avcodec.h.
1900 When the lock manager is registered, FFmpeg is guaranteed to behave
1901 correctly in a multi-threaded application.

1911 The old decoding functions are deprecated, all new code should use the
1912 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1913 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1914 argument instead of a const uint8_t *buf / int buf_size pair.

227d1b98
DB
1924 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1925 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1926 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1927 PIX_FMT_BGR32_1 are now macros.
1928 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 1929 Re-sort the enum PixelFormat list accordingly.

1943 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1944 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1945 and av_fifo_realloc2.
1946 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 1947 was changed to match av_fifo_generic_write.
