1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase or the API was added.
4 The last version increases were:
6 libavdevice: 2015-08-28
7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28
10 libpostproc: 2015-08-28
11 libswresample: 2015-08-28
12 libswscale: 2015-08-28
16 API changes, most recent first:
18 2017-03-31 - xxxxxxx - lavu 55.57.100 - spherical.h
19 Add av_spherical_projection_name().
20 Add av_spherical_from_name().
22 2017-03-30 - xxxxxxx - lavu 55.53.100 / 55.27.0 - hwcontext.h
23 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
24 Add av_hwframe_ctx_create_derived().
26 2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
27 add av_fourcc_make_string() function and av_fourcc2str() macro to replace

30 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
31 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
32 (via an entry named "rotate"). Use av_stream_get_side_data() with
33 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
34 av_display_rotation_get(). The same is done for muxing. Instead of adding a
35 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
36 to be added to the AVStream.

51 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
52 bump, and libavformat will behave as if it were always set.
53 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
55 2016-03-20 - xxxxxxx - lavu 55.50.100 / 55.21.0 - imgutils.h

69 bound_bottom, padding) to AVSphericalMapping.
71 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
72 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
73 native decoder format. (The default value is not changed.)
75 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
76 Remove requirement to use AVOption or accessors to access certain fields
77 in AVFrame, AVCodecContext, and AVFormatContext that were previously
78 documented as "no direct access" allowed.
80 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h

141 Decoders now export the frame timestamp as AVFrame.pts. It was
142 previously exported as AVFrame.pkt_pts, which is now deprecated.
144 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
145 and not the codec timebase.

186 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
187 Moved codecpar field from AVStream to the end of the struct, so that
188 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
190 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

195 Fix accidental ABI breakage in AVFilterContext.
196 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
198 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
199 compatible with lavfi>=6.47.100. Potentially also affects other users of
200 libavfilter if they are using one of the affected fields.
202 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------

249 f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
250 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
252 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
253 Add requirement to bitstream filtering API that returned packets with
254 size == 0 and side_data_elems == 0 are to be skipped by the caller.
256 2016-03-04 - 9362973 - lavf 57.28.100
257 Add protocol blacklisting API
259 2016-02-28 - 4dd4d53 - lavc 57.27.101
260 Validate AVFrame returned by get_buffer2 to have required
261 planes not NULL and unused planes set to NULL as crashes
262 and buffer overflow are possible with certain streams if
263 that is not the case.
265 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
266 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
267 the reset of the ASS ReadOrder field on flush. This affects the content of
268 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
271 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
272 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
273 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
274 The default value for this option will change to "ass" at the next major
275 libavcodec version bump.
277 The current default is "ass_with_timings" for compatibility. This means that
278 all subtitles text decoders currently still output ASS with timings printed
279 as strings in the AVSubtitles.rects[N]->ass fields.
281 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
282 timing is limited to a 1/100 time base, so this is relevant for any subtitles
283 format needing a bigger one), ease timing adjustments, and prevents the need
284 of removing the timing from the decoded string yourself. This form is also
285 known as "the Matroska form". The timing information (start time, duration)
286 can be found in the AVSubtitles fields.

1540 For audio formats with fixed frame size, the last frame
1541 no longer needs to be padded with silence, libavcodec
1542 will handle this internally (effectively all encoders
1543 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2685 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2686 Remove the next field from AVFilter, this is not anymore required.
2688 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2689 Introduce the avfilter_next() function.
2691 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2692 Change the signature of avfilter_register() to make it return an
2693 int. This is required since now the registration operation may fail.
2695 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2696 Make the pixdesc.h API public.
2698 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2720 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2721 Add a pts field to AVSubtitle which gives the subtitle packet pts
2722 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2723 not work right without this.
2725 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2726 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2727 major version. Use AV_PKT_FLAG_KEY instead.
2729 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2730 av_lockmgr_register() can be used to register a callback function
2731 that lavc (and in the future, libraries that depend on lavc) can use
2732 to implement mutexes. The application should provide a callback function
2733 that implements the AV_LOCK_* operations described in avcodec.h.
2734 When the lock manager is registered, FFmpeg is guaranteed to behave
2735 correctly in a multi-threaded application.
2737 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2738 av_free_packet() is no longer an inline function. It is now exported.
2740 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2741 Please use NULL instead. This has been supported since r16506
2742 (lavf > 52.23.1, lavc > 52.10.0).
2744 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2745 The old decoding functions are deprecated, all new code should use the
2746 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2747 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2748 argument instead of a const uint8_t *buf / int buf_size pair.
2750 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2751 Introduce the av_fifo_space() function.
2753 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2754 Move AVPacket declaration from libavformat/avformat.h to
2755 libavcodec/avcodec.h.
2757 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2758 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2759 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2760 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2761 PIX_FMT_BGR32_1 are now macros.
2762 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2763 Re-sort the enum PixelFormat list accordingly.
2764 This change breaks API/ABI backward compatibility.
2766 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2767 Add the enum PixelFormat values:
2768 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2769 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2771 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2772 The Mersenne Twister PRNG implemented through the av_random* functions
2773 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2776 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2777 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2778 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2779 and av_fifo_realloc2.
2780 In addition, the order of the function arguments of av_fifo_generic_read
2781 was changed to match av_fifo_generic_write.
2782 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2783 applications, they may not use sizeof() or directly access members.
2785 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2786 Introduce a new metadata API (see av_metadata_get() and friends).
2787 The old API is now deprecated and should not be used anymore. This especially
2788 includes the following structure fields:
2789 - AVFormatContext.title
2790 - AVFormatContext.author
2791 - AVFormatContext.copyright
2792 - AVFormatContext.comment
2793 - AVFormatContext.album
2794 - AVFormatContext.year
2795 - AVFormatContext.track
2796 - AVFormatContext.genre
2799 - AVProgram.provider_name
