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-xx-xx - xxxxxxxxxx
19 Change av_sha_update(), av_sha512_update() and av_md5_sum()/av_md5_update() length
20 parameter type to size_t at next major bump.
22 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
23 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
24 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
25 set the Cuda device handle.
27 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
30 2016-04-06 - 157e57a181 - lavc 57.92.100 - avcodec.h
31 Add AV_PKT_DATA_CONTENT_LIGHT_LEVEL packet side data.
33 2016-04-06 - b378f5bd64 - lavu 55.60.100 - mastering_display_metadata.h
34 Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
35 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
36 type to export content light level video properties.

43 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
44 Add av_hwframe_ctx_create_derived().
46 2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
47 add av_fourcc_make_string() function and av_fourcc2str() macro to replace
48 av_get_codec_tag_string() from lavc.
50 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
51 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
52 (via an entry named "rotate"). Use av_stream_get_side_data() with
53 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
54 av_display_rotation_get(). The same is done for muxing. Instead of adding a
55 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
56 to be added to the AVStream.

71 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
72 bump, and libavformat will behave as if it were always set.

88 and projection-specific properties (bound_left, bound_top, bound_right,
89 bound_bottom, padding) to AVSphericalMapping.
91 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
92 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
93 native decoder format. (The default value is not changed.)
95 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
96 Remove requirement to use AVOption or accessors to access certain fields
97 in AVFrame, AVCodecContext, and AVFormatContext that were previously
98 documented as "no direct access" allowed.
100 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
101 Add AVCodecContext.hw_device_ctx.

116 Deprecate struct vaapi_context and the vaapi.h installed header.
117 Callers should set AVCodecContext.hw_frames_ctx instead.
119 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
120 Add av_buffersink_get_*() functions.

161 Decoders now export the frame timestamp as AVFrame.pts. It was
162 previously exported as AVFrame.pkt_pts, which is now deprecated.
164 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
165 and not the codec timebase.

207 Moved codecpar field from AVStream to the end of the struct, so that
208 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
210 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
211 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

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

272 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
273 Add requirement to bitstream filtering API that returned packets with
274 size == 0 and side_data_elems == 0 are to be skipped by the caller.
276 2016-03-04 - 9362973 - lavf 57.28.100
277 Add protocol blacklisting API
279 2016-02-28 - 4dd4d53 - lavc 57.27.101
280 Validate AVFrame returned by get_buffer2 to have required
281 planes not NULL and unused planes set to NULL as crashes
282 and buffer overflow are possible with certain streams if
283 that is not the case.
285 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
286 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
287 the reset of the ASS ReadOrder field on flush. This affects the content of
288 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
291 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
292 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
293 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
294 The default value for this option will change to "ass" at the next major
295 libavcodec version bump.
297 The current default is "ass_with_timings" for compatibility. This means that
298 all subtitles text decoders currently still output ASS with timings printed
299 as strings in the AVSubtitles.rects[N]->ass fields.
301 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
302 timing is limited to a 1/100 time base, so this is relevant for any subtitles
303 format needing a bigger one), ease timing adjustments, and prevents the need
304 of removing the timing from the decoded string yourself. This form is also
305 known as "the Matroska form". The timing information (start time, duration)
306 can be found in the AVSubtitles fields.

1560 For audio formats with fixed frame size, the last frame
1561 no longer needs to be padded with silence, libavcodec
1562 will handle this internally (effectively all encoders
1563 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2708 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2709 Introduce the avfilter_next() function.
2711 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2712 Change the signature of avfilter_register() to make it return an
2713 int. This is required since now the registration operation may fail.
2715 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2716 Make the pixdesc.h API public.
2718 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2740 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2741 Add a pts field to AVSubtitle which gives the subtitle packet pts
2742 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2743 not work right without this.
2745 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2746 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2747 major version. Use AV_PKT_FLAG_KEY instead.
2749 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2750 av_lockmgr_register() can be used to register a callback function
2751 that lavc (and in the future, libraries that depend on lavc) can use
2752 to implement mutexes. The application should provide a callback function
2753 that implements the AV_LOCK_* operations described in avcodec.h.
2754 When the lock manager is registered, FFmpeg is guaranteed to behave
2755 correctly in a multi-threaded application.
2757 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2758 av_free_packet() is no longer an inline function. It is now exported.
2760 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2761 Please use NULL instead. This has been supported since r16506
2762 (lavf > 52.23.1, lavc > 52.10.0).
2764 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2765 The old decoding functions are deprecated, all new code should use the
2766 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2767 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2768 argument instead of a const uint8_t *buf / int buf_size pair.
2770 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2771 Introduce the av_fifo_space() function.
2773 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2774 Move AVPacket declaration from libavformat/avformat.h to
2775 libavcodec/avcodec.h.
2777 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2778 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2779 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2780 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2781 PIX_FMT_BGR32_1 are now macros.
2782 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2783 Re-sort the enum PixelFormat list accordingly.
2784 This change breaks API/ABI backward compatibility.
2786 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2787 Add the enum PixelFormat values:
2788 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2789 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2791 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2792 The Mersenne Twister PRNG implemented through the av_random* functions
2793 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2796 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2797 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2798 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2799 and av_fifo_realloc2.
2800 In addition, the order of the function arguments of av_fifo_generic_read
2801 was changed to match av_fifo_generic_write.
2802 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2803 applications, they may not use sizeof() or directly access members.
2805 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2806 Introduce a new metadata API (see av_metadata_get() and friends).
2807 The old API is now deprecated and should not be used anymore. This especially
2808 includes the following structure fields:
2809 - AVFormatContext.title
2810 - AVFormatContext.author
2811 - AVFormatContext.copyright
2812 - AVFormatContext.comment
2813 - AVFormatContext.album
2814 - AVFormatContext.year
2815 - AVFormatContext.track
2816 - AVFormatContext.genre
2819 - AVProgram.provider_name
