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-xx - xxxxxxx - lavf 57.68.100 - avformat.h
19 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
20 (via an entry named "rotate"). Use av_stream_get_side_data() with
21 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
22 av_display_rotation_get(). The same is done for muxing. Instead of adding a
23 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
24 to be added to the AVStream.
26 2017-03-xx - xxxxxxx - lavc 57.85.101 - avcodec.h

129 Decoders now export the frame timestamp as AVFrame.pts. It was
130 previously exported as AVFrame.pkt_pts, which is now deprecated.
132 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
133 and not the codec timebase.

174 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
175 Moved codecpar field from AVStream to the end of the struct, so that
176 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
178 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

183 Fix accidental ABI breakage in AVFilterContext.
184 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
186 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
187 compatible with lavfi>=6.47.100. Potentially also affects other users of
188 libavfilter if they are using one of the affected fields.
190 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------

241 Add requirement to bitstream filtering API that returned packets with
242 size == 0 and side_data_elems == 0 are to be skipped by the caller.
244 2016-03-04 - 9362973 - lavf 57.28.100
245 Add protocol blacklisting API
247 2016-02-28 - 4dd4d53 - lavc 57.27.101
248 Validate AVFrame returned by get_buffer2 to have required
249 planes not NULL and unused planes set to NULL as crashes
250 and buffer overflow are possible with certain streams if
251 that is not the case.
253 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
254 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
255 the reset of the ASS ReadOrder field on flush. This affects the content of
256 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
259 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
260 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
261 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
262 The default value for this option will change to "ass" at the next major
263 libavcodec version bump.
265 The current default is "ass_with_timings" for compatibility. This means that
266 all subtitles text decoders currently still output ASS with timings printed
267 as strings in the AVSubtitles.rects[N]->ass fields.
269 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
270 timing is limited to a 1/100 time base, so this is relevant for any subtitles
271 format needing a bigger one), ease timing adjustments, and prevents the need
272 of removing the timing from the decoded string yourself. This form is also
273 known as "the Matroska form". The timing information (start time, duration)
274 can be found in the AVSubtitles fields.

2673 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2674 Remove the next field from AVFilter, this is not anymore required.
2676 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2677 Introduce the avfilter_next() function.
2679 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2680 Change the signature of avfilter_register() to make it return an
2681 int. This is required since now the registration operation may fail.
2683 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2684 Make the pixdesc.h API public.
2686 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2687 Add a next field to AVFilter, this is used for simplifying the
2688 registration and management of the registered filters.
2690 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2691 Add a description field to AVFilter.
2693 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2694 Change the interface of avfilter_make_format_list() from

2696 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2698 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2699 Make avfilter_get_video_buffer() recursive and add the w and h
2702 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2703 Add w and h fields to AVFilterPic.
2705 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2706 This is now an unsigned int instead of a signed int.
2708 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2709 Add a pts field to AVSubtitle which gives the subtitle packet pts
2710 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2711 not work right without this.
2713 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2714 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2715 major version. Use AV_PKT_FLAG_KEY instead.
2717 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2718 av_lockmgr_register() can be used to register a callback function
2719 that lavc (and in the future, libraries that depend on lavc) can use
2720 to implement mutexes. The application should provide a callback function
2721 that implements the AV_LOCK_* operations described in avcodec.h.
2722 When the lock manager is registered, FFmpeg is guaranteed to behave
2723 correctly in a multi-threaded application.
2725 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2726 av_free_packet() is no longer an inline function. It is now exported.
2728 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2729 Please use NULL instead. This has been supported since r16506
2730 (lavf > 52.23.1, lavc > 52.10.0).
2732 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2733 The old decoding functions are deprecated, all new code should use the
2734 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2735 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2736 argument instead of a const uint8_t *buf / int buf_size pair.
2738 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2739 Introduce the av_fifo_space() function.
2741 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2742 Move AVPacket declaration from libavformat/avformat.h to
2743 libavcodec/avcodec.h.
2745 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2746 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2747 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2748 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2749 PIX_FMT_BGR32_1 are now macros.
2750 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2751 Re-sort the enum PixelFormat list accordingly.
2752 This change breaks API/ABI backward compatibility.
2754 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2755 Add the enum PixelFormat values:
2756 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2757 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2759 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2760 The Mersenne Twister PRNG implemented through the av_random* functions
2761 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2764 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2765 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2766 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2767 and av_fifo_realloc2.
2768 In addition, the order of the function arguments of av_fifo_generic_read
2769 was changed to match av_fifo_generic_write.
2770 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2771 applications, they may not use sizeof() or directly access members.
2773 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2774 Introduce a new metadata API (see av_metadata_get() and friends).
2775 The old API is now deprecated and should not be used anymore. This especially
2776 includes the following structure fields:
2777 - AVFormatContext.title
2778 - AVFormatContext.author
2779 - AVFormatContext.copyright
2780 - AVFormatContext.comment
2781 - AVFormatContext.album
2782 - AVFormatContext.year
2783 - AVFormatContext.track
2784 - AVFormatContext.genre
2787 - AVProgram.provider_name
