1942 correctly in a multi-threaded application.
1944 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1945 av_free_packet() is no longer an inline function. It is now exported.
1947 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1948 Please use NULL instead. This has been supported since r16506
1949 (lavf > 52.23.1, lavc > 52.10.0).
1951 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1952 The old decoding functions are deprecated, all new code should use the
1953 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1954 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1955 argument instead of a const uint8_t *buf / int buf_size pair.
1957 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1958 Introduce the av_fifo_space() function.
1960 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1961 Move AVPacket declaration from libavformat/avformat.h to
1962 libavcodec/avcodec.h.
1964 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1965 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1966 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1967 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1968 PIX_FMT_BGR32_1 are now macros.
1969 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1970 Re-sort the enum PixelFormat list accordingly.
1971 This change breaks API/ABI backward compatibility.
1973 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1974 Add the enum PixelFormat values:
1975 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1976 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1978 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1979 The Mersenne Twister PRNG implemented through the av_random* functions
1980 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1983 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1984 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1985 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1986 and av_fifo_realloc2.
1987 In addition, the order of the function arguments of av_fifo_generic_read
1988 was changed to match av_fifo_generic_write.
1989 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1990 applications, they may not use sizeof() or directly access members.
1992 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1993 Introduce a new metadata API (see av_metadata_get() and friends).
1994 The old API is now deprecated and should not be used anymore. This especially
1995 includes the following structure fields:
1996 - AVFormatContext.title
1997 - AVFormatContext.author
1998 - AVFormatContext.copyright
1999 - AVFormatContext.comment
2000 - AVFormatContext.album
2001 - AVFormatContext.year
2002 - AVFormatContext.track
2003 - AVFormatContext.genre
2006 - AVProgram.provider_name
