1944 Make the pixdesc.h API public.
1946 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1947 Add a next field to AVFilter, this is used for simplifying the
1948 registration and management of the registered filters.
1950 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1951 Add a description field to AVFilter.
1953 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1954 Change the interface of avfilter_make_format_list() from
1955 avfilter_make_format_list(int n, ...) to
1956 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1958 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1959 Make avfilter_get_video_buffer() recursive and add the w and h
1962 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1963 Add w and h fields to AVFilterPic.
1965 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1966 This is now an unsigned int instead of a signed int.
1968 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1969 Add a pts field to AVSubtitle which gives the subtitle packet pts
1970 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1971 not work right without this.
1973 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1974 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1975 major version. Use AV_PKT_FLAG_KEY instead.
1977 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1978 av_lockmgr_register() can be used to register a callback function
1979 that lavc (and in the future, libraries that depend on lavc) can use
1980 to implement mutexes. The application should provide a callback function
1981 that implements the AV_LOCK_* operations described in avcodec.h.
1982 When the lock manager is registered, FFmpeg is guaranteed to behave
1983 correctly in a multi-threaded application.
1985 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1986 av_free_packet() is no longer an inline function. It is now exported.
1988 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1989 Please use NULL instead. This has been supported since r16506
1990 (lavf > 52.23.1, lavc > 52.10.0).
1992 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1993 The old decoding functions are deprecated, all new code should use the
1994 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1995 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1996 argument instead of a const uint8_t *buf / int buf_size pair.
1998 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1999 Introduce the av_fifo_space() function.
2001 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2002 Move AVPacket declaration from libavformat/avformat.h to
2003 libavcodec/avcodec.h.
2005 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2006 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2007 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2008 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2009 PIX_FMT_BGR32_1 are now macros.
2010 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2011 Re-sort the enum PixelFormat list accordingly.
2012 This change breaks API/ABI backward compatibility.
2014 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2015 Add the enum PixelFormat values:
2016 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2017 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2019 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2020 The Mersenne Twister PRNG implemented through the av_random* functions
2021 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2024 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2025 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2026 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2027 and av_fifo_realloc2.
2028 In addition, the order of the function arguments of av_fifo_generic_read
2029 was changed to match av_fifo_generic_write.
2030 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2031 applications, they may not use sizeof() or directly access members.
2033 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2034 Introduce a new metadata API (see av_metadata_get() and friends).
2035 The old API is now deprecated and should not be used anymore. This especially
2036 includes the following structure fields:
2037 - AVFormatContext.title
2038 - AVFormatContext.author
2039 - AVFormatContext.copyright
2040 - AVFormatContext.comment
2041 - AVFormatContext.album
2042 - AVFormatContext.year
2043 - AVFormatContext.track
2044 - AVFormatContext.genre
2047 - AVProgram.provider_name
