14 API changes, most recent first:
15
16 2012-xx-xx - lavc 53.34.0
17 New audio encoding API:
18 xxxxxxx Add CODEC_CAP_VARIABLE_FRAME_SIZE capability for use by audio
19 encoders.
20 xxxxxxx Add avcodec_fill_audio_frame() as a convenience function.
21 xxxxxxx Add avcodec_encode_audio2() and deprecate avcodec_encode_audio().
22 Add AVCodec.encode2().
23
24 2012-01-xx - xxxxxxx - lavfi 2.15.0
25 Add a new installed header -- libavfilter/version.h -- with version macros.
26
27 2011-01-03 - b73ec05 - lavu 51.21.0
28 Add av_popcount64
29
30 2011-12-25 - lavfi 2.14.0
31 e1d9dbf Add a new installed header - buffersrc.h
32 It contains a new function av_buffersrc_buffer() that allows passing
33 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
34 it allows for direct rendering.
35 1c9e340 Add avfilter_copy_frame_props() for copying properties from
36 AVFrame to AVFilterBufferRef.
37
38 2011-12-25 - lavc 53.31.0
39 Add the following new fields to AVFrame:
40 b58dbb5 sample_aspect_ratio
41 3a2ddf7 width, height
42 8a4a5f6 format
43
44 2011-12-18 - 8400b12 - lavc 53.28.1
45 Deprecate AVFrame.age. The field is unused.
46
47 2011-12-12 - 5266045 - lavf 53.17.0
48 Add avformat_close_input().
49 Deprecate av_close_input_file() and av_close_input_stream().
50
51 2011-12-02 - 0eea212 - lavc 53.25.0
52 Add nb_samples and extended_data fields to AVFrame.
53 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
54 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
55 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
56 audio decoders to use get_buffer().
57
58 2011-12-04 - 560f773 - lavc 53.24.0
59 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.
60 Change AVPicture.data[4]/linesize[4] to [8] at next major bump.

62 Add AV_NUM_DATA_POINTERS to simplify the bump transition.
63
64 2011-11-23 - bbb46f3 - lavu 51.18.0
65 Add av_samples_get_buffer_size(), av_samples_fill_arrays(), and
66 av_samples_alloc(), to samplefmt.h.

68 2011-11-23 - 8889cc4 - lavu 51.17.0
69 Add planar sample formats and av_sample_fmt_is_planar() to samplefmt.h.
70
71 2011-11-19 - f3a29b7 - lavc 53.21.0
72 Move some AVCodecContext fields to a new private struct, AVCodecInternal,
73 which is accessed from a new field, AVCodecContext.internal.
74 - fields moved:
75 AVCodecContext.internal_buffer --> AVCodecInternal.buffer
76 AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
77 AVCodecContext.is_copy --> AVCodecInternal.is_copy
78
79 2011-11-16 - 6270671 - lavu 51.16.0
80 Add av_timegm()
81
82 2011-11-13 - lavf 53.15.0
83 New interrupt callback API, allowing per-AVFormatContext/AVIOContext
84 interrupt callbacks.
85 6aa0b98 Add AVIOInterruptCB struct and the interrupt_callback field to
86 AVFormatContext.
87 1dee0ac Add avio_open2() with additional parameters. Those are
88 an interrupt callback and an options AVDictionary.

90 54.0.

867 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
868 Change the signature of avfilter_register() to make it return an

900
901 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
902 PKT_FLAG_KEY has been deprecated and will be dropped at the next
903 major version. Use AV_PKT_FLAG_KEY instead.
904
905 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
906 av_lockmgr_register() can be used to register a callback function
907 that lavc (and in the future, libraries that depend on lavc) can use
908 to implement mutexes. The application should provide a callback function
909 that implements the AV_LOCK_* operations described in avcodec.h.
910 When the lock manager is registered, FFmpeg is guaranteed to behave
911 correctly in a multi-threaded application.
912
913 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
914 av_free_packet() is no longer an inline function. It is now exported.
915
916 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
917 Please use NULL instead. This has been supported since r16506
918 (lavf > 52.23.1, lavc > 52.10.0).
919
920 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
921 The old decoding functions are deprecated, all new code should use the
922 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
923 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
924 argument instead of a const uint8_t *buf / int buf_size pair.
925
926 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
927 Introduce the av_fifo_space() function.
928
929 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
930 Move AVPacket declaration from libavformat/avformat.h to
931 libavcodec/avcodec.h.
932
933 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
934 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
935 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
936 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
937 PIX_FMT_BGR32_1 are now macros.
938 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
939 Re-sort the enum PixelFormat list accordingly.
940 This change breaks API/ABI backward compatibility.
941
942 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
943 Add the enum PixelFormat values:
944 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
945 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
946
947 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
948 The Mersenne Twister PRNG implemented through the av_random* functions
949 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
950 instead.
951
952 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
953 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
954 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
955 and av_fifo_realloc2.
956 In addition, the order of the function arguments of av_fifo_generic_read
957 was changed to match av_fifo_generic_write.
958 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
959 applications, they may not use sizeof() or directly access members.
960
961 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
962 Introduce a new metadata API (see av_metadata_get() and friends).
963 The old API is now deprecated and should not be used anymore. This especially
964 includes the following structure fields:
965 - AVFormatContext.title
966 - AVFormatContext.author
967 - AVFormatContext.copyright
968 - AVFormatContext.comment
969 - AVFormatContext.album
970 - AVFormatContext.year
971 - AVFormatContext.track
972 - AVFormatContext.genre
973 - AVStream.language
974 - AVStream.filename
975 - AVProgram.provider_name
976 - AVProgram.name
977 - AVChapter.title
