  Note that this can break user code that includes avcodec.h and uses the
  'CodecID' identifier. Such code should either #undef CodecID or stop using the
  CodecID name.

733 734 735 736 737
  For audio formats with fixed frame size, the last frame
  no longer needs to be padded with silence, libavcodec

  not work right without this.

1902
2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1903
  PKT_FLAG_KEY has been deprecated and will be dropped at the next

1907 1908 1909
  av_lockmgr_register() can be used to register a callback function
  that lavc (and in the future, libraries that depend on lavc) can use
  to implement mutexes. The application should provide a callback function
1910 1911 1912
  that implements the AV_LOCK_* operations described in avcodec.h.
  When the lock manager is registered, FFmpeg is guaranteed to behave
  correctly in a multi-threaded application.
1913

1914
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

1917
2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1918 1919 1920

1921
2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1922 1923 1924 1925 1926
  The old decoding functions are deprecated, all new code should use the
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  argument instead of a const uint8_t *buf / int buf_size pair.

1927
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1928 1929

1934
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1935 1936 1937 1938 1939
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  PIX_FMT_BGR32_1 are now macros.
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1940
  Re-sort the enum PixelFormat list accordingly.
1941 1942
  This change breaks API/ABI backward compatibility.

1943
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1944 1945 1946 1947

  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1948
2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
1949 1950 1951 1952
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

1953
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
1954 1955 1956 1957
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  and av_fifo_realloc2.
  In addition, the order of the function arguments of av_fifo_generic_read
1958
  was changed to match av_fifo_generic_write.
1959 1960
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
1961

1962
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1963 1964
