1945 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1946 major version. Use AV_PKT_FLAG_KEY instead.
1948 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1949 av_lockmgr_register() can be used to register a callback function
1950 that lavc (and in the future, libraries that depend on lavc) can use
1951 to implement mutexes. The application should provide a callback function
1952 that implements the AV_LOCK_* operations described in avcodec.h.
1953 When the lock manager is registered, FFmpeg is guaranteed to behave
1954 correctly in a multi-threaded application.
1956 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1957 av_free_packet() is no longer an inline function. It is now exported.
1959 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1960 Please use NULL instead. This has been supported since r16506
1961 (lavf > 52.23.1, lavc > 52.10.0).
1963 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1964 The old decoding functions are deprecated, all new code should use the
1965 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1966 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1967 argument instead of a const uint8_t *buf / int buf_size pair.
1969 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1970 Introduce the av_fifo_space() function.
1972 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1973 Move AVPacket declaration from libavformat/avformat.h to
1974 libavcodec/avcodec.h.
1976 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1977 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1978 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1979 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1980 PIX_FMT_BGR32_1 are now macros.
1981 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1982 Re-sort the enum PixelFormat list accordingly.
1983 This change breaks API/ABI backward compatibility.
1985 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1986 Add the enum PixelFormat values:
1987 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1988 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1990 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1991 The Mersenne Twister PRNG implemented through the av_random* functions
1992 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1995 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1996 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1997 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1998 and av_fifo_realloc2.
1999 In addition, the order of the function arguments of av_fifo_generic_read
2000 was changed to match av_fifo_generic_write.
2001 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2002 applications, they may not use sizeof() or directly access members.
2004 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2005 Introduce a new metadata API (see av_metadata_get() and friends).
2006 The old API is now deprecated and should not be used anymore. This especially
2007 includes the following structure fields:
2008 - AVFormatContext.title
2009 - AVFormatContext.author
2010 - AVFormatContext.copyright
2011 - AVFormatContext.comment
2012 - AVFormatContext.album
2013 - AVFormatContext.year
2014 - AVFormatContext.track
2015 - AVFormatContext.genre
2018 - AVProgram.provider_name
