852 For audio formats with fixed frame size, the last frame
853 no longer needs to be padded with silence, libavcodec
854 will handle this internally (effectively all encoders
855 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

1991 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1992 Introduce the avfilter_next() function.
1994 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1995 Change the signature of avfilter_register() to make it return an
1996 int. This is required since now the registration operation may fail.
1998 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1999 Make the pixdesc.h API public.
2001 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2006 Add a description field to AVFilter.
2008 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2009 Change the interface of avfilter_make_format_list() from

2023 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2024 Add a pts field to AVSubtitle which gives the subtitle packet pts
2025 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2026 not work right without this.
2028 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2029 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2030 major version. Use AV_PKT_FLAG_KEY instead.
2032 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2033 av_lockmgr_register() can be used to register a callback function
2034 that lavc (and in the future, libraries that depend on lavc) can use
2035 to implement mutexes. The application should provide a callback function
2036 that implements the AV_LOCK_* operations described in avcodec.h.
2037 When the lock manager is registered, FFmpeg is guaranteed to behave
2038 correctly in a multi-threaded application.
2040 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2041 av_free_packet() is no longer an inline function. It is now exported.
2043 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2044 Please use NULL instead. This has been supported since r16506
2045 (lavf > 52.23.1, lavc > 52.10.0).
2047 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2048 The old decoding functions are deprecated, all new code should use the
2049 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2050 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2051 argument instead of a const uint8_t *buf / int buf_size pair.
2053 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2054 Introduce the av_fifo_space() function.
2056 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2057 Move AVPacket declaration from libavformat/avformat.h to
2058 libavcodec/avcodec.h.
2060 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2061 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2062 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2063 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2064 PIX_FMT_BGR32_1 are now macros.
2065 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2066 Re-sort the enum PixelFormat list accordingly.
2067 This change breaks API/ABI backward compatibility.
2069 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2070 Add the enum PixelFormat values:
2071 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2072 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2074 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2075 The Mersenne Twister PRNG implemented through the av_random* functions
2076 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2079 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2080 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2081 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2082 and av_fifo_realloc2.
2083 In addition, the order of the function arguments of av_fifo_generic_read
2084 was changed to match av_fifo_generic_write.
2085 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2086 applications, they may not use sizeof() or directly access members.
2088 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2089 Introduce a new metadata API (see av_metadata_get() and friends).
2090 The old API is now deprecated and should not be used anymore. This especially
2091 includes the following structure fields:
2092 - AVFormatContext.title
2093 - AVFormatContext.author
2094 - AVFormatContext.copyright
2095 - AVFormatContext.comment
2096 - AVFormatContext.album
2097 - AVFormatContext.year
2098 - AVFormatContext.track
2099 - AVFormatContext.genre
2102 - AVProgram.provider_name
