343bfdd3 18632009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
0c13bbf5

1864 Please use NULL instead. This has been supported since r16506
1865 (lavf > 52.23.1, lavc > 52.10.0).

2851d225
RB
1868 The old decoding functions are deprecated, all new code should use the
1869 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1870 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1871 argument instead of a const uint8_t *buf / int buf_size pair.

343bfdd3 18802009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
227d1b98
DB
1881 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1882 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1883 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1884 PIX_FMT_BGR32_1 are now macros.
1885 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 1886 Re-sort the enum PixelFormat list accordingly.

1890 Add the enum PixelFormat values:
1891 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1892 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

c8f742ca

1895 The Mersenne Twister PRNG implemented through the av_random* functions
1896 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1897 instead.

343bfdd3 18992009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
889cdae8
DB
1900 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1901 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1902 and av_fifo_realloc2.
1903 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 1904 was changed to match av_fifo_generic_write.
889cdae8
DB
1905 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1906 applications, they may not use sizeof() or directly access members.
