2027 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2028 Introduce the avfilter_next() function.
2030 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2031 Change the signature of avfilter_register() to make it return an
2032 int. This is required since now the registration operation may fail.
2034 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2035 Make the pixdesc.h API public.

2059 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2060 Add a pts field to AVSubtitle which gives the subtitle packet pts
2061 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2062 not work right without this.
2064 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2065 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2066 major version. Use AV_PKT_FLAG_KEY instead.
2068 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2069 av_lockmgr_register() can be used to register a callback function
2070 that lavc (and in the future, libraries that depend on lavc) can use
2071 to implement mutexes. The application should provide a callback function
2072 that implements the AV_LOCK_* operations described in avcodec.h.
2073 When the lock manager is registered, FFmpeg is guaranteed to behave
2074 correctly in a multi-threaded application.
2076 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2077 av_free_packet() is no longer an inline function. It is now exported.
2079 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2080 Please use NULL instead. This has been supported since r16506
2081 (lavf > 52.23.1, lavc > 52.10.0).
2083 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2084 The old decoding functions are deprecated, all new code should use the
2085 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2086 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2087 argument instead of a const uint8_t *buf / int buf_size pair.
2089 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2090 Introduce the av_fifo_space() function.
2092 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2093 Move AVPacket declaration from libavformat/avformat.h to
2094 libavcodec/avcodec.h.
2096 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2097 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2098 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2099 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2100 PIX_FMT_BGR32_1 are now macros.
2101 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2102 Re-sort the enum PixelFormat list accordingly.
2103 This change breaks API/ABI backward compatibility.
2105 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2106 Add the enum PixelFormat values:
2107 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2108 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2110 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2111 The Mersenne Twister PRNG implemented through the av_random* functions
2112 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2115 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2116 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2117 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2118 and av_fifo_realloc2.
2119 In addition, the order of the function arguments of av_fifo_generic_read
2120 was changed to match av_fifo_generic_write.
2121 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2122 applications, they may not use sizeof() or directly access members.
2124 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2125 Introduce a new metadata API (see av_metadata_get() and friends).
2126 The old API is now deprecated and should not be used anymore. This especially
2127 includes the following structure fields:
2128 - AVFormatContext.title
2129 - AVFormatContext.author
2130 - AVFormatContext.copyright
2131 - AVFormatContext.comment
2132 - AVFormatContext.album
2133 - AVFormatContext.year
2134 - AVFormatContext.track
2135 - AVFormatContext.genre
2138 - AVProgram.provider_name
