1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase.
4 The last version increases were:
6 libavdevice: 2011-04-18
7 libavfilter: 2011-04-18
8 libavformat: 2012-01-27
9 libavresample: 2012-04-24
10 libswscale: 2011-06-20
14 API changes, most recent first:
16 2012-05-15 - lavfi 2.17.0
17 Add support for audio filters
18 ac71230/a2cd9be - add video/audio buffer sink in a new installed
20 720c6b7 - add av_buffersrc_write_frame(), deprecate
21 av_vsrc_buffer_add_frame()
22 ab16504 - add avfilter_copy_buf_props()
23 9453c9e - add extended_data to AVFilterBuffer

32 no longer needs to be padded with silence, libavcodec
33 will handle this internally (effectively all encoders
34 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

122 f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible
123 buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for

149 it allows for direct rendering.
150 1c9e340 Add avfilter_copy_frame_props() for copying properties from
151 AVFrame to AVFilterBufferRef.
153 2011-12-25 - lavc 53.31.0

988 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
989 Introduce the avfilter_next() function.
991 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
992 Change the signature of avfilter_register() to make it return an
993 int. This is required since now the registration operation may fail.

996 Make the pixdesc.h API public.

1017 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

1020 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1021 Add a pts field to AVSubtitle which gives the subtitle packet pts
1022 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1023 not work right without this.
1025 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1026 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1027 major version. Use AV_PKT_FLAG_KEY instead.
1029 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1030 av_lockmgr_register() can be used to register a callback function
1031 that lavc (and in the future, libraries that depend on lavc) can use
1032 to implement mutexes. The application should provide a callback function
1033 that implements the AV_LOCK_* operations described in avcodec.h.
1034 When the lock manager is registered, FFmpeg is guaranteed to behave
1035 correctly in a multi-threaded application.
1037 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1038 av_free_packet() is no longer an inline function. It is now exported.
1040 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1041 Please use NULL instead. This has been supported since r16506
1042 (lavf > 52.23.1, lavc > 52.10.0).
1044 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1045 The old decoding functions are deprecated, all new code should use the
1046 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1047 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1048 argument instead of a const uint8_t *buf / int buf_size pair.
1050 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1051 Introduce the av_fifo_space() function.
1053 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1054 Move AVPacket declaration from libavformat/avformat.h to
1055 libavcodec/avcodec.h.
1057 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1058 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1059 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1060 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1061 PIX_FMT_BGR32_1 are now macros.
1062 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1063 Re-sort the enum PixelFormat list accordingly.
1064 This change breaks API/ABI backward compatibility.
1066 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1067 Add the enum PixelFormat values:
1068 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1069 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1071 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1072 The Mersenne Twister PRNG implemented through the av_random* functions
1073 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1076 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1077 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1078 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1079 and av_fifo_realloc2.
1080 In addition, the order of the function arguments of av_fifo_generic_read
1081 was changed to match av_fifo_generic_write.
1082 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1083 applications, they may not use sizeof() or directly access members.
1085 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1086 Introduce a new metadata API (see av_metadata_get() and friends).
1087 The old API is now deprecated and should not be used anymore. This especially
1088 includes the following structure fields:
1089 - AVFormatContext.title
1090 - AVFormatContext.author
1091 - AVFormatContext.copyright
1092 - AVFormatContext.comment
1093 - AVFormatContext.album
1094 - AVFormatContext.year
1095 - AVFormatContext.track
1096 - AVFormatContext.genre
1099 - AVProgram.provider_name
