900 Change the avfilter_add_colorspace() signature, make it accept an
901 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
903 2010-01-03 - r21007 - lavfi 1.13.0 - avfilter_add_colorspace()

923 Introduce the av_bmg_next() function.
925 2009-12-05 - r20734 - lavfi 1.12.0 - avfilter_draw_slice()
926 Add a slice_dir parameter to avfilter_draw_slice().
928 2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
929 Remove the next field from AVFilter, this is not anymore required.
931 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
932 Introduce the avfilter_next() function.
934 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
935 Change the signature of avfilter_register() to make it return an
936 int. This is required since now the registration operation may fail.
938 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
939 Make the pixdesc.h API public.
941 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
942 Add a next field to AVFilter, this is used for simplifying the
943 registration and management of the registered filters.
945 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
946 Add a description field to AVFilter.
948 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()

953 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
954 Make avfilter_get_video_buffer() recursive and add the w and h
957 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic

960 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
961 This is now an unsigned int instead of a signed int.
963 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
964 Add a pts field to AVSubtitle which gives the subtitle packet pts
965 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
966 not work right without this.
968 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
969 PKT_FLAG_KEY has been deprecated and will be dropped at the next
970 major version. Use AV_PKT_FLAG_KEY instead.
972 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
973 av_lockmgr_register() can be used to register a callback function
974 that lavc (and in the future, libraries that depend on lavc) can use
975 to implement mutexes. The application should provide a callback function
976 that implements the AV_LOCK_* operations described in avcodec.h.
977 When the lock manager is registered, FFmpeg is guaranteed to behave
978 correctly in a multi-threaded application.
980 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
981 av_free_packet() is no longer an inline function. It is now exported.
983 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
984 Please use NULL instead. This has been supported since r16506
985 (lavf > 52.23.1, lavc > 52.10.0).
987 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
988 The old decoding functions are deprecated, all new code should use the
989 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
990 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
991 argument instead of a const uint8_t *buf / int buf_size pair.
993 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
994 Introduce the av_fifo_space() function.
996 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
997 Move AVPacket declaration from libavformat/avformat.h to
998 libavcodec/avcodec.h.
1000 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
1001 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1002 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1003 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1004 PIX_FMT_BGR32_1 are now macros.
1005 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1006 Re-sort the enum PixelFormat list accordingly.
1007 This change breaks API/ABI backward compatibility.
1009 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1010 Add the enum PixelFormat values:
1011 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1012 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1014 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
1015 The Mersenne Twister PRNG implemented through the av_random* functions
1016 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1019 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
1020 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1021 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1022 and av_fifo_realloc2.
1023 In addition, the order of the function arguments of av_fifo_generic_read
1024 was changed to match av_fifo_generic_write.
1025 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1026 applications, they may not use sizeof() or directly access members.
1028 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
1029 Introduce a new metadata API (see av_metadata_get() and friends).
1030 The old API is now deprecated and should not be used anymore. This especially
1031 includes the following structure fields:
1032 - AVFormatContext.title
1033 - AVFormatContext.author
1034 - AVFormatContext.copyright
1035 - AVFormatContext.comment
1036 - AVFormatContext.album
1037 - AVFormatContext.year
1038 - AVFormatContext.track
1039 - AVFormatContext.genre
1042 - AVProgram.provider_name
