1925 The old decoding functions are deprecated, all new code should use the
1926 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1927 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1928 argument instead of a const uint8_t *buf / int buf_size pair.

1941 PIX_FMT_BGR32_1 are now macros.
1942 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1943 Re-sort the enum PixelFormat list accordingly.
1944 This change breaks API/ABI backward compatibility.
1946 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1947 Add the enum PixelFormat values:
1948 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1949 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1951 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1952 The Mersenne Twister PRNG implemented through the av_random* functions
1953 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1956 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1957 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1958 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1959 and av_fifo_realloc2.
1960 In addition, the order of the function arguments of av_fifo_generic_read
1961 was changed to match av_fifo_generic_write.
1962 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1963 applications, they may not use sizeof() or directly access members.
1965 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1966 Introduce a new metadata API (see av_metadata_get() and friends).
1967 The old API is now deprecated and should not be used anymore. This especially
1968 includes the following structure fields:
1969 - AVFormatContext.title
1970 - AVFormatContext.author
1971 - AVFormatContext.copyright
1972 - AVFormatContext.comment
1973 - AVFormatContext.album
1974 - AVFormatContext.year
1975 - AVFormatContext.track
1976 - AVFormatContext.genre
1979 - AVProgram.provider_name
