f988ce6c
1868 av_lockmgr_register() can be used to register a callback function
1869 that lavc (and in the future, libraries that depend on lavc) can use
1870 to implement mutexes. The application should provide a callback function
227d1b98
DB
1871 that implements the AV_LOCK_* operations described in avcodec.h.
1872 When the lock manager is registered, FFmpeg is guaranteed to behave
1873 correctly in a multi-threaded application.

343bfdd3 18782009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
0c13bbf5

1879 Please use NULL instead. This has been supported since r16506
1880 (lavf > 52.23.1, lavc > 52.10.0).

2851d225
RB
1883 The old decoding functions are deprecated, all new code should use the
1884 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1885 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1886 argument instead of a const uint8_t *buf / int buf_size pair.

343bfdd3 18952009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
227d1b98
DB
1896 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1897 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1898 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1899 PIX_FMT_BGR32_1 are now macros.
1900 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 1901 Re-sort the enum PixelFormat list accordingly.

1905 Add the enum PixelFormat values:
1906 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1907 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1910 The Mersenne Twister PRNG implemented through the av_random* functions
1911 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1912 instead.

DB
1915 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1916 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1917 and av_fifo_realloc2.
1918 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 1919 was changed to match av_fifo_generic_write.

DB
1920 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1921 applications, they may not use sizeof() or directly access members.
