1933 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
1934 Add av_match_ext(), it should be used in place of match_ext().
1936 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
1937 Add av_guess_format(), it should be used in place of guess_format().

1940 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
1941 AV_METADATA_DONT_STRDUP_VAL.
1943 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

1950 Introduce the av_bmg_next() function.
1952 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
1953 Add a slice_dir parameter to avfilter_draw_slice().
1955 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1956 Remove the next field from AVFilter, this is not anymore required.
1958 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1959 Introduce the avfilter_next() function.
1961 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1962 Change the signature of avfilter_register() to make it return an
1963 int. This is required since now the registration operation may fail.
1965 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1966 Make the pixdesc.h API public.
1968 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1973 Add a description field to AVFilter.
1975 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1976 Change the interface of avfilter_make_format_list() from

1987 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

1990 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1991 Add a pts field to AVSubtitle which gives the subtitle packet pts
1992 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1993 not work right without this.
1995 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1996 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1997 major version. Use AV_PKT_FLAG_KEY instead.
1999 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2000 av_lockmgr_register() can be used to register a callback function
2001 that lavc (and in the future, libraries that depend on lavc) can use
2002 to implement mutexes. The application should provide a callback function
2003 that implements the AV_LOCK_* operations described in avcodec.h.
2004 When the lock manager is registered, FFmpeg is guaranteed to behave
2005 correctly in a multi-threaded application.
2007 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2008 av_free_packet() is no longer an inline function. It is now exported.
2010 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2011 Please use NULL instead. This has been supported since r16506
2012 (lavf > 52.23.1, lavc > 52.10.0).
2014 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2015 The old decoding functions are deprecated, all new code should use the
2016 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2017 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2018 argument instead of a const uint8_t *buf / int buf_size pair.
2020 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2021 Introduce the av_fifo_space() function.
2023 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2024 Move AVPacket declaration from libavformat/avformat.h to
2025 libavcodec/avcodec.h.
2027 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2028 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2029 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2030 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2031 PIX_FMT_BGR32_1 are now macros.
2032 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2033 Re-sort the enum PixelFormat list accordingly.
2034 This change breaks API/ABI backward compatibility.
2036 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2037 Add the enum PixelFormat values:
2038 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2039 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2041 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2042 The Mersenne Twister PRNG implemented through the av_random* functions
2043 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2046 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2047 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2048 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2049 and av_fifo_realloc2.
2050 In addition, the order of the function arguments of av_fifo_generic_read
2051 was changed to match av_fifo_generic_write.
2052 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2053 applications, they may not use sizeof() or directly access members.
2055 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2056 Introduce a new metadata API (see av_metadata_get() and friends).
2057 The old API is now deprecated and should not be used anymore. This especially
2058 includes the following structure fields:
2059 - AVFormatContext.title
2060 - AVFormatContext.author
2061 - AVFormatContext.copyright
2062 - AVFormatContext.comment
2063 - AVFormatContext.album
2064 - AVFormatContext.year
2065 - AVFormatContext.track
2066 - AVFormatContext.genre
2069 - AVProgram.provider_name
