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 2016-04-06 - xxxxxxx - lavc 57.92.100 - avcodec.h
19 Add AV_PKT_DATA_CONTENT_LIGHT_LEVEL packet side data.
21 2016-04-06 - xxxxxxx - lavu 55.60.100 - mastering_display_metadata.h
22 Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
23 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
24 type to export content light level video properties.
26 2017-03-31 - xxxxxxx - lavu 55.57.100 - spherical.h
27 Add av_spherical_projection_name().
28 Add av_spherical_from_name().
30 2017-03-30 - xxxxxxx - lavu 55.53.100 / 55.27.0 - hwcontext.h
31 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
32 Add av_hwframe_ctx_create_derived().
34 2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
35 add av_fourcc_make_string() function and av_fourcc2str() macro to replace

39 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
40 (via an entry named "rotate"). Use av_stream_get_side_data() with
41 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
42 av_display_rotation_get(). The same is done for muxing. Instead of adding a
43 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
44 to be added to the AVStream.

77 bound_bottom, padding) to AVSphericalMapping.
79 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
80 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
81 native decoder format. (The default value is not changed.)
83 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
84 Remove requirement to use AVOption or accessors to access certain fields
85 in AVFrame, AVCodecContext, and AVFormatContext that were previously
86 documented as "no direct access" allowed.

149 Decoders now export the frame timestamp as AVFrame.pts. It was
150 previously exported as AVFrame.pkt_pts, which is now deprecated.
152 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
153 and not the codec timebase.

180 field in AVCodecParameters.
182 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
183 Add a new API for chained BSF filters and passthrough (null) BSF --

194 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
195 Moved codecpar field from AVStream to the end of the struct, so that
196 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
198 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

202 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
203 Fix accidental ABI breakage in AVFilterContext.
204 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
206 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
207 compatible with lavfi>=6.47.100. Potentially also affects other users of
208 libavfilter if they are using one of the affected fields.

257 f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
258 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
260 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
261 Add requirement to bitstream filtering API that returned packets with
262 size == 0 and side_data_elems == 0 are to be skipped by the caller.
264 2016-03-04 - 9362973 - lavf 57.28.100
265 Add protocol blacklisting API
267 2016-02-28 - 4dd4d53 - lavc 57.27.101
268 Validate AVFrame returned by get_buffer2 to have required
269 planes not NULL and unused planes set to NULL as crashes
270 and buffer overflow are possible with certain streams if
271 that is not the case.
273 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
274 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
275 the reset of the ASS ReadOrder field on flush. This affects the content of
276 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
279 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
280 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
281 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
282 The default value for this option will change to "ass" at the next major
283 libavcodec version bump.
285 The current default is "ass_with_timings" for compatibility. This means that
286 all subtitles text decoders currently still output ASS with timings printed
287 as strings in the AVSubtitles.rects[N]->ass fields.
289 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
290 timing is limited to a 1/100 time base, so this is relevant for any subtitles
291 format needing a bigger one), ease timing adjustments, and prevents the need
292 of removing the timing from the decoded string yourself. This form is also
293 known as "the Matroska form". The timing information (start time, duration)
294 can be found in the AVSubtitles fields.

1548 For audio formats with fixed frame size, the last frame
1549 no longer needs to be padded with silence, libavcodec
1550 will handle this internally (effectively all encoders
1551 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2696 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2697 Introduce the avfilter_next() function.
2699 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2700 Change the signature of avfilter_register() to make it return an
2701 int. This is required since now the registration operation may fail.

2728 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2729 Add a pts field to AVSubtitle which gives the subtitle packet pts
2730 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2731 not work right without this.
2733 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2734 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2735 major version. Use AV_PKT_FLAG_KEY instead.
2737 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2738 av_lockmgr_register() can be used to register a callback function
2739 that lavc (and in the future, libraries that depend on lavc) can use
2740 to implement mutexes. The application should provide a callback function
2741 that implements the AV_LOCK_* operations described in avcodec.h.
2742 When the lock manager is registered, FFmpeg is guaranteed to behave
2743 correctly in a multi-threaded application.
2745 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2746 av_free_packet() is no longer an inline function. It is now exported.
2748 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2749 Please use NULL instead. This has been supported since r16506
2750 (lavf > 52.23.1, lavc > 52.10.0).
2752 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2753 The old decoding functions are deprecated, all new code should use the
2754 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2755 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2756 argument instead of a const uint8_t *buf / int buf_size pair.
2758 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2759 Introduce the av_fifo_space() function.
2761 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2762 Move AVPacket declaration from libavformat/avformat.h to
2763 libavcodec/avcodec.h.
2765 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2766 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2767 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2768 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2769 PIX_FMT_BGR32_1 are now macros.
2770 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2771 Re-sort the enum PixelFormat list accordingly.
2772 This change breaks API/ABI backward compatibility.
2774 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2775 Add the enum PixelFormat values:
2776 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2777 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2779 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2780 The Mersenne Twister PRNG implemented through the av_random* functions
2781 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2784 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2785 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2786 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2787 and av_fifo_realloc2.
2788 In addition, the order of the function arguments of av_fifo_generic_read
2789 was changed to match av_fifo_generic_write.
2790 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2791 applications, they may not use sizeof() or directly access members.
2793 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2794 Introduce a new metadata API (see av_metadata_get() and friends).
2795 The old API is now deprecated and should not be used anymore. This especially
2796 includes the following structure fields:
2797 - AVFormatContext.title
2798 - AVFormatContext.author
2799 - AVFormatContext.copyright
2800 - AVFormatContext.comment
2801 - AVFormatContext.album
2802 - AVFormatContext.year
2803 - AVFormatContext.track
2804 - AVFormatContext.genre
2807 - AVProgram.provider_name
