981 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
982 Change the signature of avfilter_register() to make it return an
983 int. This is required since now the registration operation may fail.

1010 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
1011 Add a pts field to AVSubtitle which gives the subtitle packet pts
1012 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1013 not work right without this.
1015 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1016 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1017 major version. Use AV_PKT_FLAG_KEY instead.
1019 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
1020 av_lockmgr_register() can be used to register a callback function
1021 that lavc (and in the future, libraries that depend on lavc) can use
1022 to implement mutexes. The application should provide a callback function
1023 that implements the AV_LOCK_* operations described in avcodec.h.
1024 When the lock manager is registered, FFmpeg is guaranteed to behave
1025 correctly in a multi-threaded application.
1027 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
1028 av_free_packet() is no longer an inline function. It is now exported.
1030 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1031 Please use NULL instead. This has been supported since r16506
1032 (lavf > 52.23.1, lavc > 52.10.0).
1034 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1035 The old decoding functions are deprecated, all new code should use the
1036 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1037 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1038 argument instead of a const uint8_t *buf / int buf_size pair.
1040 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
1041 Introduce the av_fifo_space() function.
1043 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
1044 Move AVPacket declaration from libavformat/avformat.h to
1045 libavcodec/avcodec.h.
1047 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
1048 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1049 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1050 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1051 PIX_FMT_BGR32_1 are now macros.
1052 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1053 Re-sort the enum PixelFormat list accordingly.
1054 This change breaks API/ABI backward compatibility.
1056 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1057 Add the enum PixelFormat values:
1058 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1059 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1061 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
1062 The Mersenne Twister PRNG implemented through the av_random* functions
1063 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1066 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
1067 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1068 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1069 and av_fifo_realloc2.
1070 In addition, the order of the function arguments of av_fifo_generic_read
1071 was changed to match av_fifo_generic_write.
1072 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1073 applications, they may not use sizeof() or directly access members.
1075 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
1076 Introduce a new metadata API (see av_metadata_get() and friends).
1077 The old API is now deprecated and should not be used anymore. This especially
1078 includes the following structure fields:
1079 - AVFormatContext.title
1080 - AVFormatContext.author
1081 - AVFormatContext.copyright
1082 - AVFormatContext.comment
1083 - AVFormatContext.album
1084 - AVFormatContext.year
1085 - AVFormatContext.track
1086 - AVFormatContext.genre
1089 - AVProgram.provider_name
