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.

76 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
77 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
78 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
79 set the Cuda device handle.
81 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

105 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
106 (via an entry named "rotate"). Use av_stream_get_side_data() with
107 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
108 av_display_rotation_get(). The same is done for muxing. Instead of adding a
109 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
110 to be added to the AVStream.

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

136 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
137 Deprecate AVFilterGraph.resample_lavr_opts
138 It's never been used by avfilter nor passed to anything.

141 Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
142 and projection-specific properties (bound_left, bound_top, bound_right,
143 bound_bottom, padding) to AVSphericalMapping.
145 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
146 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
147 native decoder format. (The default value is not changed.)
149 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
150 Remove requirement to use AVOption or accessors to access certain fields
151 in AVFrame, AVCodecContext, and AVFormatContext that were previously
152 documented as "no direct access" allowed.

215 Decoders now export the frame timestamp as AVFrame.pts. It was
216 previously exported as AVFrame.pkt_pts, which is now deprecated.
218 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
219 and not the codec timebase.

242 Add AVFilterContext.nb_threads.
244 2016-08-15 - c3c4c72 - lavc 57.53.100 - avcodec.h
245 Add trailing_padding to AVCodecContext to match the corresponding
246 field in AVCodecParameters.
248 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
249 Add a new API for chained BSF filters and passthrough (null) BSF --

260 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
261 Moved codecpar field from AVStream to the end of the struct, so that
262 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
264 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
265 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
266 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
268 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
269 Fix accidental ABI breakage in AVFilterContext.
270 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
272 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
273 compatible with lavfi>=6.47.100. Potentially also affects other users of
274 libavfilter if they are using one of the affected fields.
276 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
278 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

313 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
314 Add AVHWFramesConstraints and associated API.

323 f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
324 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
326 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
327 Add requirement to bitstream filtering API that returned packets with
328 size == 0 and side_data_elems == 0 are to be skipped by the caller.
330 2016-03-04 - 9362973 - lavf 57.28.100
331 Add protocol blacklisting API
333 2016-02-28 - 4dd4d53 - lavc 57.27.101
334 Validate AVFrame returned by get_buffer2 to have required
335 planes not NULL and unused planes set to NULL as crashes
336 and buffer overflow are possible with certain streams if
337 that is not the case.
339 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
340 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
341 the reset of the ASS ReadOrder field on flush. This affects the content of
342 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
345 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
346 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
347 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
348 The default value for this option will change to "ass" at the next major
349 libavcodec version bump.
351 The current default is "ass_with_timings" for compatibility. This means that
352 all subtitles text decoders currently still output ASS with timings printed
353 as strings in the AVSubtitles.rects[N]->ass fields.
355 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
356 timing is limited to a 1/100 time base, so this is relevant for any subtitles
357 format needing a bigger one), ease timing adjustments, and prevents the need
358 of removing the timing from the decoded string yourself. This form is also
359 known as "the Matroska form". The timing information (start time, duration)
360 can be found in the AVSubtitles fields.

2799 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2800 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2801 major version. Use AV_PKT_FLAG_KEY instead.
2803 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2804 av_lockmgr_register() can be used to register a callback function
2805 that lavc (and in the future, libraries that depend on lavc) can use
2806 to implement mutexes. The application should provide a callback function
2807 that implements the AV_LOCK_* operations described in avcodec.h.
2808 When the lock manager is registered, FFmpeg is guaranteed to behave
2809 correctly in a multi-threaded application.
2811 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2812 av_free_packet() is no longer an inline function. It is now exported.
2814 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2815 Please use NULL instead. This has been supported since r16506
2816 (lavf > 52.23.1, lavc > 52.10.0).
2818 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2819 The old decoding functions are deprecated, all new code should use the
2820 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2821 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2822 argument instead of a const uint8_t *buf / int buf_size pair.
2824 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2825 Introduce the av_fifo_space() function.
2827 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2828 Move AVPacket declaration from libavformat/avformat.h to
2829 libavcodec/avcodec.h.
2831 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2832 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2833 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2834 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2835 PIX_FMT_BGR32_1 are now macros.
2836 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2837 Re-sort the enum PixelFormat list accordingly.
2838 This change breaks API/ABI backward compatibility.
2840 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2841 Add the enum PixelFormat values:
2842 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2843 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2845 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2846 The Mersenne Twister PRNG implemented through the av_random* functions
2847 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2850 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2851 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2852 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2853 and av_fifo_realloc2.
2854 In addition, the order of the function arguments of av_fifo_generic_read
2855 was changed to match av_fifo_generic_write.
2856 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2857 applications, they may not use sizeof() or directly access members.
2859 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2860 Introduce a new metadata API (see av_metadata_get() and friends).
2861 The old API is now deprecated and should not be used anymore. This especially
2862 includes the following structure fields:
2863 - AVFormatContext.title
2864 - AVFormatContext.author
2865 - AVFormatContext.copyright
2866 - AVFormatContext.comment
2867 - AVFormatContext.album
2868 - AVFormatContext.year
2869 - AVFormatContext.track
2870 - AVFormatContext.genre
2873 - AVProgram.provider_name
