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 2017-03-30 - xxxxxxx - lavu 55.53.100 / 55.27.0 - hwcontext.h
19 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
20 Add av_hwframe_ctx_create_derived().
22 2017-03-xx - xxxxxxx - lavu 55.52.100 - avutil.h

27 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
28 (via an entry named "rotate"). Use av_stream_get_side_data() with
29 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
30 av_display_rotation_get(). The same is done for muxing. Instead of adding a
31 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
32 to be added to the AVStream.
34 2017-03-xx - xxxxxxx - lavc 57.85.101 - avcodec.h

63 Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
64 and projection-specific properties (bound_left, bound_top, bound_right,
65 bound_bottom, padding) to AVSphericalMapping.
67 2017-03-02 - xxxxxxx - lavc 57.81.104 - videotoolbox.h
68 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
69 native decoder format. (The default value is not changed.)
71 2017-03-02 - xxxxxxx - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
72 Remove requirement to use AVOption or accessors to access certain fields
73 in AVFrame, AVCodecContext, and AVFormatContext that were previously
74 documented as "no direct access" allowed.
76 2017-02-13 - xxxxxxx - lavc 57.80.100 - avcodec.h

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

182 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
183 Moved codecpar field from AVStream to the end of the struct, so that
184 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
186 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

191 Fix accidental ABI breakage in AVFilterContext.
192 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
194 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
195 compatible with lavfi>=6.47.100. Potentially also affects other users of
196 libavfilter if they are using one of the affected fields.

249 Add requirement to bitstream filtering API that returned packets with
250 size == 0 and side_data_elems == 0 are to be skipped by the caller.
252 2016-03-04 - 9362973 - lavf 57.28.100
253 Add protocol blacklisting API
255 2016-02-28 - 4dd4d53 - lavc 57.27.101
256 Validate AVFrame returned by get_buffer2 to have required
257 planes not NULL and unused planes set to NULL as crashes
258 and buffer overflow are possible with certain streams if
259 that is not the case.
261 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
262 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
263 the reset of the ASS ReadOrder field on flush. This affects the content of
264 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
267 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
268 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
269 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
270 The default value for this option will change to "ass" at the next major
271 libavcodec version bump.
273 The current default is "ass_with_timings" for compatibility. This means that
274 all subtitles text decoders currently still output ASS with timings printed
275 as strings in the AVSubtitles.rects[N]->ass fields.
277 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
278 timing is limited to a 1/100 time base, so this is relevant for any subtitles
279 format needing a bigger one), ease timing adjustments, and prevents the need
280 of removing the timing from the decoded string yourself. This form is also
281 known as "the Matroska form". The timing information (start time, duration)
282 can be found in the AVSubtitles fields.

2681 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2682 Remove the next field from AVFilter, this is not anymore required.
2684 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2685 Introduce the avfilter_next() function.
2687 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2688 Change the signature of avfilter_register() to make it return an
2689 int. This is required since now the registration operation may fail.
2691 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2692 Make the pixdesc.h API public.
2694 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2699 Add a description field to AVFilter.
2701 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2702 Change the interface of avfilter_make_format_list() from

2716 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2717 Add a pts field to AVSubtitle which gives the subtitle packet pts
2718 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2719 not work right without this.
2721 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2722 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2723 major version. Use AV_PKT_FLAG_KEY instead.
2725 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2726 av_lockmgr_register() can be used to register a callback function
2727 that lavc (and in the future, libraries that depend on lavc) can use
2728 to implement mutexes. The application should provide a callback function
2729 that implements the AV_LOCK_* operations described in avcodec.h.
2730 When the lock manager is registered, FFmpeg is guaranteed to behave
2731 correctly in a multi-threaded application.
2733 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2734 av_free_packet() is no longer an inline function. It is now exported.
2736 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2737 Please use NULL instead. This has been supported since r16506
2738 (lavf > 52.23.1, lavc > 52.10.0).
2740 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2741 The old decoding functions are deprecated, all new code should use the
2742 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2743 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2744 argument instead of a const uint8_t *buf / int buf_size pair.
2746 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2747 Introduce the av_fifo_space() function.
2749 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2750 Move AVPacket declaration from libavformat/avformat.h to
2751 libavcodec/avcodec.h.
2753 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2754 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2755 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2756 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2757 PIX_FMT_BGR32_1 are now macros.
2758 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2759 Re-sort the enum PixelFormat list accordingly.
2760 This change breaks API/ABI backward compatibility.
2762 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2763 Add the enum PixelFormat values:
2764 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2765 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2767 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2768 The Mersenne Twister PRNG implemented through the av_random* functions
2769 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2772 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2773 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2774 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2775 and av_fifo_realloc2.
2776 In addition, the order of the function arguments of av_fifo_generic_read
2777 was changed to match av_fifo_generic_write.
2778 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2779 applications, they may not use sizeof() or directly access members.
2781 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2782 Introduce a new metadata API (see av_metadata_get() and friends).
2783 The old API is now deprecated and should not be used anymore. This especially
2784 includes the following structure fields:
2785 - AVFormatContext.title
2786 - AVFormatContext.author
2787 - AVFormatContext.copyright
2788 - AVFormatContext.comment
2789 - AVFormatContext.album
2790 - AVFormatContext.year
2791 - AVFormatContext.track
2792 - AVFormatContext.genre
2795 - AVProgram.provider_name
