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 - lavu 55.52.100 - avutil.h
19 add av_fourcc_make_string() function and av_fourcc2str() macro to replace
20 av_get_codec_tag_string() from lavc.
22 2017-03-xx - xxxxxxx - lavf 57.68.100 - avformat.h
23 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
24 (via an entry named "rotate"). Use av_stream_get_side_data() with
25 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
26 av_display_rotation_get(). The same is done for muxing. Instead of adding a
27 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
28 to be added to the AVStream.
30 2017-03-xx - xxxxxxx - lavc 57.85.101 - avcodec.h

64 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
65 native decoder format. (The default value is not changed.)
67 2017-03-02 - xxxxxxx - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
68 Remove requirement to use AVOption or accessors to access certain fields
69 in AVFrame, AVCodecContext, and AVFormatContext that were previously
70 documented as "no direct access" allowed.
72 2017-02-13 - xxxxxxx - lavc 57.80.100 - avcodec.h

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

178 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
179 Moved codecpar field from AVStream to the end of the struct, so that
180 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
182 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

187 Fix accidental ABI breakage in AVFilterContext.
188 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
190 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
191 compatible with lavfi>=6.47.100. Potentially also affects other users of
192 libavfilter if they are using one of the affected fields.
194 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
196 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

245 Add requirement to bitstream filtering API that returned packets with
246 size == 0 and side_data_elems == 0 are to be skipped by the caller.
248 2016-03-04 - 9362973 - lavf 57.28.100
249 Add protocol blacklisting API
251 2016-02-28 - 4dd4d53 - lavc 57.27.101
252 Validate AVFrame returned by get_buffer2 to have required
253 planes not NULL and unused planes set to NULL as crashes
254 and buffer overflow are possible with certain streams if
255 that is not the case.
257 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
258 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
259 the reset of the ASS ReadOrder field on flush. This affects the content of
260 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
263 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
264 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
265 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
266 The default value for this option will change to "ass" at the next major
267 libavcodec version bump.
269 The current default is "ass_with_timings" for compatibility. This means that
270 all subtitles text decoders currently still output ASS with timings printed
271 as strings in the AVSubtitles.rects[N]->ass fields.
273 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
274 timing is limited to a 1/100 time base, so this is relevant for any subtitles
275 format needing a bigger one), ease timing adjustments, and prevents the need
276 of removing the timing from the decoded string yourself. This form is also
277 known as "the Matroska form". The timing information (start time, duration)
278 can be found in the AVSubtitles fields.

2677 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2678 Remove the next field from AVFilter, this is not anymore required.
2680 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2681 Introduce the avfilter_next() function.
2683 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2684 Change the signature of avfilter_register() to make it return an
2685 int. This is required since now the registration operation may fail.
2687 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2688 Make the pixdesc.h API public.
2690 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2691 Add a next field to AVFilter, this is used for simplifying the
2692 registration and management of the registered filters.

2695 Add a description field to AVFilter.
2697 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2698 Change the interface of avfilter_make_format_list() from

2707 Add w and h fields to AVFilterPic.
2709 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2710 This is now an unsigned int instead of a signed int.
2712 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2713 Add a pts field to AVSubtitle which gives the subtitle packet pts
2714 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2715 not work right without this.
2717 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2718 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2719 major version. Use AV_PKT_FLAG_KEY instead.
2721 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2722 av_lockmgr_register() can be used to register a callback function
2723 that lavc (and in the future, libraries that depend on lavc) can use
2724 to implement mutexes. The application should provide a callback function
2725 that implements the AV_LOCK_* operations described in avcodec.h.
2726 When the lock manager is registered, FFmpeg is guaranteed to behave
2727 correctly in a multi-threaded application.
2729 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2730 av_free_packet() is no longer an inline function. It is now exported.
2732 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2733 Please use NULL instead. This has been supported since r16506
2734 (lavf > 52.23.1, lavc > 52.10.0).
2736 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2737 The old decoding functions are deprecated, all new code should use the
2738 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2739 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2740 argument instead of a const uint8_t *buf / int buf_size pair.
2742 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2743 Introduce the av_fifo_space() function.
2745 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2746 Move AVPacket declaration from libavformat/avformat.h to
2747 libavcodec/avcodec.h.
2749 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2750 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2751 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2752 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2753 PIX_FMT_BGR32_1 are now macros.
2754 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2755 Re-sort the enum PixelFormat list accordingly.
2756 This change breaks API/ABI backward compatibility.
2758 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2759 Add the enum PixelFormat values:
2760 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2761 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2763 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2764 The Mersenne Twister PRNG implemented through the av_random* functions
2765 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2768 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2769 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2770 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2771 and av_fifo_realloc2.
2772 In addition, the order of the function arguments of av_fifo_generic_read
2773 was changed to match av_fifo_generic_write.
2774 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2775 applications, they may not use sizeof() or directly access members.
2777 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2778 Introduce a new metadata API (see av_metadata_get() and friends).
2779 The old API is now deprecated and should not be used anymore. This especially
2780 includes the following structure fields:
2781 - AVFormatContext.title
2782 - AVFormatContext.author
2783 - AVFormatContext.copyright
2784 - AVFormatContext.comment
2785 - AVFormatContext.album
2786 - AVFormatContext.year
2787 - AVFormatContext.track
2788 - AVFormatContext.genre
2791 - AVProgram.provider_name
