1943 Introduce the avfilter_next() function.
1945 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1946 Change the signature of avfilter_register() to make it return an
1947 int. This is required since now the registration operation may fail.
1949 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1950 Make the pixdesc.h API public.
1952 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1953 Add a next field to AVFilter, this is used for simplifying the
1954 registration and management of the registered filters.
1956 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1957 Add a description field to AVFilter.
1959 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1960 Change the interface of avfilter_make_format_list() from
1961 avfilter_make_format_list(int n, ...) to
1962 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1964 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1965 Make avfilter_get_video_buffer() recursive and add the w and h
1968 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1969 Add w and h fields to AVFilterPic.
1971 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1972 This is now an unsigned int instead of a signed int.
1974 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1975 Add a pts field to AVSubtitle which gives the subtitle packet pts
1976 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1977 not work right without this.
1979 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1980 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1981 major version. Use AV_PKT_FLAG_KEY instead.
1983 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1984 av_lockmgr_register() can be used to register a callback function
1985 that lavc (and in the future, libraries that depend on lavc) can use
1986 to implement mutexes. The application should provide a callback function
1987 that implements the AV_LOCK_* operations described in avcodec.h.
1988 When the lock manager is registered, FFmpeg is guaranteed to behave
1989 correctly in a multi-threaded application.
1991 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1992 av_free_packet() is no longer an inline function. It is now exported.
1994 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1995 Please use NULL instead. This has been supported since r16506
1996 (lavf > 52.23.1, lavc > 52.10.0).
1998 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1999 The old decoding functions are deprecated, all new code should use the
2000 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2001 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2002 argument instead of a const uint8_t *buf / int buf_size pair.
2004 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2005 Introduce the av_fifo_space() function.
2007 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2008 Move AVPacket declaration from libavformat/avformat.h to
2009 libavcodec/avcodec.h.
2011 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2012 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2013 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2014 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2015 PIX_FMT_BGR32_1 are now macros.
2016 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2017 Re-sort the enum PixelFormat list accordingly.
2018 This change breaks API/ABI backward compatibility.
2020 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2021 Add the enum PixelFormat values:
2022 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2023 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2025 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2026 The Mersenne Twister PRNG implemented through the av_random* functions
2027 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2030 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2031 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2032 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2033 and av_fifo_realloc2.
2034 In addition, the order of the function arguments of av_fifo_generic_read
2035 was changed to match av_fifo_generic_write.
2036 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2037 applications, they may not use sizeof() or directly access members.
2039 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2040 Introduce a new metadata API (see av_metadata_get() and friends).
2041 The old API is now deprecated and should not be used anymore. This especially
2042 includes the following structure fields:
2043 - AVFormatContext.title
2044 - AVFormatContext.author
2045 - AVFormatContext.copyright
2046 - AVFormatContext.comment
2047 - AVFormatContext.album
2048 - AVFormatContext.year
2049 - AVFormatContext.track
2050 - AVFormatContext.genre
2053 - AVProgram.provider_name
