1946 Add w and h fields to AVFilterPic.
1948 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1949 This is now an unsigned int instead of a signed int.
1951 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1952 Add a pts field to AVSubtitle which gives the subtitle packet pts
1953 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1954 not work right without this.
1956 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1957 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1958 major version. Use AV_PKT_FLAG_KEY instead.
1960 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1961 av_lockmgr_register() can be used to register a callback function
1962 that lavc (and in the future, libraries that depend on lavc) can use
1963 to implement mutexes. The application should provide a callback function
1964 that implements the AV_LOCK_* operations described in avcodec.h.
1965 When the lock manager is registered, FFmpeg is guaranteed to behave
1966 correctly in a multi-threaded application.
1968 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1969 av_free_packet() is no longer an inline function. It is now exported.
1971 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1972 Please use NULL instead. This has been supported since r16506
1973 (lavf > 52.23.1, lavc > 52.10.0).
1975 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1976 The old decoding functions are deprecated, all new code should use the
1977 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1978 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1979 argument instead of a const uint8_t *buf / int buf_size pair.
1981 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1982 Introduce the av_fifo_space() function.
1984 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1985 Move AVPacket declaration from libavformat/avformat.h to
1986 libavcodec/avcodec.h.
1988 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1989 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1990 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1991 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1992 PIX_FMT_BGR32_1 are now macros.
1993 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1994 Re-sort the enum PixelFormat list accordingly.
1995 This change breaks API/ABI backward compatibility.
1997 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1998 Add the enum PixelFormat values:
1999 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2000 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2002 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2003 The Mersenne Twister PRNG implemented through the av_random* functions
2004 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2007 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2008 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2009 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2010 and av_fifo_realloc2.
2011 In addition, the order of the function arguments of av_fifo_generic_read
2012 was changed to match av_fifo_generic_write.
2013 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2014 applications, they may not use sizeof() or directly access members.
2016 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2017 Introduce a new metadata API (see av_metadata_get() and friends).
2018 The old API is now deprecated and should not be used anymore. This especially
2019 includes the following structure fields:
2020 - AVFormatContext.title
2021 - AVFormatContext.author
2022 - AVFormatContext.copyright
2023 - AVFormatContext.comment
2024 - AVFormatContext.album
2025 - AVFormatContext.year
2026 - AVFormatContext.track
2027 - AVFormatContext.genre
2030 - AVProgram.provider_name
