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

16 API changes, most recent first:
18 2017-xx-xx - xxxxxxx - lavu 55.62.100 / 55.30.0 - frame.h
19 Add AVFrame.crop_left/right/top/bottom fields for attaching cropping
20 information to video frames.
22 2017-xx-xx - xxxxxxxxxx
23 Change av_sha_update(), av_sha512_update() and av_md5_sum()/av_md5_update() length
24 parameter type to size_t at next major bump.
26 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
27 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
28 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
29 set the Cuda device handle.
31 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
34 2016-04-06 - 157e57a181 - lavc 57.92.100 - avcodec.h
35 Add AV_PKT_DATA_CONTENT_LIGHT_LEVEL packet side data.
37 2016-04-06 - b378f5bd64 - lavu 55.60.100 - mastering_display_metadata.h
38 Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
39 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
40 type to export content light level video properties.

47 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
48 Add av_hwframe_ctx_create_derived().
50 2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
51 add av_fourcc_make_string() function and av_fourcc2str() macro to replace

54 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
55 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
56 (via an entry named "rotate"). Use av_stream_get_side_data() with
57 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
58 av_display_rotation_get(). The same is done for muxing. Instead of adding a
59 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
60 to be added to the AVStream.

75 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
76 bump, and libavformat will behave as if it were always set.
77 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
79 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h
80 Add av_image_copy_uc_from(), a version of av_image_copy() for copying
81 from GPU mapped memory.
83 2017-03-20 - 9c2436e - lavu 55.49.100 - pixdesc.h

91 Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
92 and projection-specific properties (bound_left, bound_top, bound_right,
93 bound_bottom, padding) to AVSphericalMapping.
95 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
96 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
97 native decoder format. (The default value is not changed.)
99 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
100 Remove requirement to use AVOption or accessors to access certain fields
101 in AVFrame, AVCodecContext, and AVFormatContext that were previously
102 documented as "no direct access" allowed.
104 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
105 Add AVCodecContext.hw_device_ctx.
107 2017-02-11 - e3af49b14b - lavu 55.47.100 - frame.h

120 Deprecate struct vaapi_context and the vaapi.h installed header.
121 Callers should set AVCodecContext.hw_frames_ctx instead.
123 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
124 Add av_buffersink_get_*() functions.

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

210 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
211 Moved codecpar field from AVStream to the end of the struct, so that
212 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
214 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
215 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

218 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
219 Fix accidental ABI breakage in AVFilterContext.
220 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
222 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
223 compatible with lavfi>=6.47.100. Potentially also affects other users of
224 libavfilter if they are using one of the affected fields.

258 Add AVFilterContext.hw_device_ctx.
260 2016-04-14 - 28abb21 / 551c677 - lavu 55.22.100 / 55.9.0 - hwcontext_vaapi.h
261 Add new installed header with VAAPI-specific hwcontext definitions.
263 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
264 Add AVHWFramesConstraints and associated API.

274 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
276 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
277 Add requirement to bitstream filtering API that returned packets with
278 size == 0 and side_data_elems == 0 are to be skipped by the caller.
280 2016-03-04 - 9362973 - lavf 57.28.100
281 Add protocol blacklisting API
283 2016-02-28 - 4dd4d53 - lavc 57.27.101
284 Validate AVFrame returned by get_buffer2 to have required
285 planes not NULL and unused planes set to NULL as crashes
286 and buffer overflow are possible with certain streams if
287 that is not the case.
289 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
290 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
291 the reset of the ASS ReadOrder field on flush. This affects the content of
292 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
295 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
296 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
297 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
298 The default value for this option will change to "ass" at the next major
299 libavcodec version bump.
301 The current default is "ass_with_timings" for compatibility. This means that
302 all subtitles text decoders currently still output ASS with timings printed
303 as strings in the AVSubtitles.rects[N]->ass fields.
305 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
306 timing is limited to a 1/100 time base, so this is relevant for any subtitles
307 format needing a bigger one), ease timing adjustments, and prevents the need
308 of removing the timing from the decoded string yourself. This form is also
309 known as "the Matroska form". The timing information (start time, duration)
310 can be found in the AVSubtitles fields.

1564 For audio formats with fixed frame size, the last frame
1565 no longer needs to be padded with silence, libavcodec
1566 will handle this internally (effectively all encoders
1567 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2712 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2713 Introduce the avfilter_next() function.
2715 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2716 Change the signature of avfilter_register() to make it return an
2717 int. This is required since now the registration operation may fail.
2719 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2720 Make the pixdesc.h API public.
2722 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2744 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2745 Add a pts field to AVSubtitle which gives the subtitle packet pts
2746 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2747 not work right without this.
2749 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2750 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2751 major version. Use AV_PKT_FLAG_KEY instead.
2753 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2754 av_lockmgr_register() can be used to register a callback function
2755 that lavc (and in the future, libraries that depend on lavc) can use
2756 to implement mutexes. The application should provide a callback function
2757 that implements the AV_LOCK_* operations described in avcodec.h.
2758 When the lock manager is registered, FFmpeg is guaranteed to behave
2759 correctly in a multi-threaded application.
2761 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2762 av_free_packet() is no longer an inline function. It is now exported.
2764 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2765 Please use NULL instead. This has been supported since r16506
2766 (lavf > 52.23.1, lavc > 52.10.0).
2768 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2769 The old decoding functions are deprecated, all new code should use the
2770 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2771 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2772 argument instead of a const uint8_t *buf / int buf_size pair.
2774 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2775 Introduce the av_fifo_space() function.
2777 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2778 Move AVPacket declaration from libavformat/avformat.h to
2779 libavcodec/avcodec.h.
2781 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2782 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2783 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2784 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2785 PIX_FMT_BGR32_1 are now macros.
2786 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2787 Re-sort the enum PixelFormat list accordingly.
2788 This change breaks API/ABI backward compatibility.
2790 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2791 Add the enum PixelFormat values:
2792 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2793 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2795 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2796 The Mersenne Twister PRNG implemented through the av_random* functions
2797 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2800 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2801 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2802 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2803 and av_fifo_realloc2.
2804 In addition, the order of the function arguments of av_fifo_generic_read
2805 was changed to match av_fifo_generic_write.
2806 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2807 applications, they may not use sizeof() or directly access members.
2809 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2810 Introduce a new metadata API (see av_metadata_get() and friends).
2811 The old API is now deprecated and should not be used anymore. This especially
2812 includes the following structure fields:
2813 - AVFormatContext.title
2814 - AVFormatContext.author
2815 - AVFormatContext.copyright
2816 - AVFormatContext.comment
2817 - AVFormatContext.album
2818 - AVFormatContext.year
2819 - AVFormatContext.track
2820 - AVFormatContext.genre
2823 - AVProgram.provider_name
