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 libpostproc: 2011-04-18 (deprecated, to be removed later)
10 libswscale: 2011-06-20
14 API changes, most recent first:

22 2012-02-01 - 316fc74 - lavc 54.01.0
23 Add av_fast_padded_malloc() as alternative for av_realloc() when aligned
24 memory is required. The buffer will always have FF_INPUT_BUFFER_PADDING_SIZE
25 zero-padded bytes at the end.
27 2012-01-31 - dd6d3b0 - lavf 54.01.0
28 Add avformat_get_riff_video_tags() and avformat_get_riff_audio_tags().

38 f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible
39 buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for
40 muxers supporting it (av_write_frame makes sure it is called
41 only for muxers with this flag).
43 2012-01-15 - lavc 53.34.0
44 New audio encoding API:
45 b2c75b6 Add CODEC_CAP_VARIABLE_FRAME_SIZE capability for use by audio

57 2011-12-25 - lavfi 2.14.0
58 e1d9dbf Add a new installed header - buffersrc.h
59 It contains a new function av_buffersrc_buffer() that allows passing
60 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
61 it allows for direct rendering.
62 1c9e340 Add avfilter_copy_frame_props() for copying properties from
63 AVFrame to AVFilterBufferRef.
65 2011-12-25 - lavc 53.31.0

874 2009-12-13 - r20834 - lavf 52.43.0 - metadata API
875 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
876 AV_METADATA_DONT_STRDUP_VAL.
878 2009-12-13 - r20829 - lavu 50.7.0 - avstring.h API
881 2009-12-13 - r20826 - lavc 52.42.0 - AVStream
884 2009-12-12 - r20808 - lavu 50.6.0 - av_bmg_next()
885 Introduce the av_bmg_next() function.
887 2009-12-05 - r20734 - lavfi 1.12.0 - avfilter_draw_slice()
888 Add a slice_dir parameter to avfilter_draw_slice().
890 2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
891 Remove the next field from AVFilter, this is not anymore required.
893 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
894 Introduce the avfilter_next() function.
896 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
897 Change the signature of avfilter_register() to make it return an
898 int. This is required since now the registration operation may fail.
900 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
901 Make the pixdesc.h API public.
903 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
904 Add a next field to AVFilter, this is used for simplifying the
905 registration and management of the registered filters.
907 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
908 Add a description field to AVFilter.
910 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
911 Change the interface of avfilter_make_format_list() from
912 avfilter_make_format_list(int n, ...) to
913 avfilter_make_format_list(enum PixelFormat *pix_fmts).
915 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
916 Make avfilter_get_video_buffer() recursive and add the w and h
919 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
920 Add w and h fields to AVFilterPic.
922 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
923 This is now an unsigned int instead of a signed int.
925 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
926 Add a pts field to AVSubtitle which gives the subtitle packet pts
927 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
928 not work right without this.
930 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
931 PKT_FLAG_KEY has been deprecated and will be dropped at the next
932 major version. Use AV_PKT_FLAG_KEY instead.
934 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
935 av_lockmgr_register() can be used to register a callback function
936 that lavc (and in the future, libraries that depend on lavc) can use
937 to implement mutexes. The application should provide a callback function
938 that implements the AV_LOCK_* operations described in avcodec.h.
939 When the lock manager is registered, FFmpeg is guaranteed to behave
940 correctly in a multi-threaded application.
942 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
943 av_free_packet() is no longer an inline function. It is now exported.
945 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
946 Please use NULL instead. This has been supported since r16506
947 (lavf > 52.23.1, lavc > 52.10.0).
949 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
950 The old decoding functions are deprecated, all new code should use the
951 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
952 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
953 argument instead of a const uint8_t *buf / int buf_size pair.
955 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
956 Introduce the av_fifo_space() function.
958 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
959 Move AVPacket declaration from libavformat/avformat.h to
960 libavcodec/avcodec.h.
962 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
963 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
964 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
965 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
966 PIX_FMT_BGR32_1 are now macros.
967 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
968 Re-sort the enum PixelFormat list accordingly.
969 This change breaks API/ABI backward compatibility.
971 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
972 Add the enum PixelFormat values:
973 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
974 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
976 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
977 The Mersenne Twister PRNG implemented through the av_random* functions
978 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
981 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
982 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
983 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
984 and av_fifo_realloc2.
985 In addition, the order of the function arguments of av_fifo_generic_read
986 was changed to match av_fifo_generic_write.
987 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
988 applications, they may not use sizeof() or directly access members.
990 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
991 Introduce a new metadata API (see av_metadata_get() and friends).
992 The old API is now deprecated and should not be used anymore. This especially
993 includes the following structure fields:
994 - AVFormatContext.title
995 - AVFormatContext.author
996 - AVFormatContext.copyright
997 - AVFormatContext.comment
998 - AVFormatContext.album
999 - AVFormatContext.year
1000 - AVFormatContext.track
1001 - AVFormatContext.genre
1004 - AVProgram.provider_name
