  Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
  To provide backwards compatibility, PixelFormat is now #defined as
  AVPixelFormat.
  Note that this can break user code that includes pixfmt.h and uses the
  'PixelFormat' identifier. Such code should either #undef PixelFormat
  or stop using the PixelFormat name.

795 796 797 798 799
  For audio formats with fixed frame size, the last frame
  no longer needs to be padded with silence, libavcodec
  will handle this internally (effectively all encoders
  behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

  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
1972 1973 1974
  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.

1976
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1977 1978
  av_free_packet() is no longer an inline function. It is now exported.

1979
2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1980 1981 1982
  Please use NULL instead. This has been supported since r16506
  (lavf > 52.23.1, lavc > 52.10.0).

1983
2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1984 1985 1986 1987 1988
  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.

1989
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1990 1991
  Introduce the av_fifo_space() function.

1992
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1993 1994 1995
  Move AVPacket declaration from libavformat/avformat.h to
  libavcodec/avcodec.h.

1996
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1997 1998 1999 2000 2001
  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.
2002
  Re-sort the enum PixelFormat list accordingly.
2003 2004
  This change breaks API/ABI backward compatibility.

2005
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2006 2007 2008 2009
  Add the enum PixelFormat values:
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

2010
2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
2011 2012 2013 2014
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

2015
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
2016 2017 2018 2019
  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
2020
  was changed to match av_fifo_generic_write.
2021 2022
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
2023

2024
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2025 2026
  Introduce a new metadata API (see av_metadata_get() and friends).
  The old API is now deprecated and should not be used anymore. This especially
