6 libavdevice: 2015-08-28
7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28

11 libswresample: 2015-08-28
12 libswscale: 2015-08-28
16 API changes, most recent first:
18 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
21 2016-04-06 - 157e57a181 - lavc 57.92.100 - avcodec.h
22 Add AV_PKT_DATA_CONTENT_LIGHT_LEVEL packet side data.
24 2016-04-06 - b378f5bd64 - lavu 55.60.100 - mastering_display_metadata.h
25 Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
26 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
27 type to export content light level video properties.

30 Add av_spherical_projection_name().
31 Add av_spherical_from_name().

34 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
35 Add av_hwframe_ctx_create_derived().
37 2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h

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

62 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
63 bump, and libavformat will behave as if it were always set.
64 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
66 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

82 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
83 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
84 native decoder format. (The default value is not changed.)
86 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
87 Remove requirement to use AVOption or accessors to access certain fields
88 in AVFrame, AVCodecContext, and AVFormatContext that were previously

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

197 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
198 Moved codecpar field from AVStream to the end of the struct, so that
199 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
201 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

206 Fix accidental ABI breakage in AVFilterContext.
207 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
209 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
210 compatible with lavfi>=6.47.100. Potentially also affects other users of
211 libavfilter if they are using one of the affected fields.
213 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
215 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

260 f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
261 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
263 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
264 Add requirement to bitstream filtering API that returned packets with
265 size == 0 and side_data_elems == 0 are to be skipped by the caller.
267 2016-03-04 - 9362973 - lavf 57.28.100
268 Add protocol blacklisting API
270 2016-02-28 - 4dd4d53 - lavc 57.27.101
271 Validate AVFrame returned by get_buffer2 to have required
272 planes not NULL and unused planes set to NULL as crashes
273 and buffer overflow are possible with certain streams if
274 that is not the case.
276 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
277 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
278 the reset of the ASS ReadOrder field on flush. This affects the content of
279 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
282 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
283 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
284 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
285 The default value for this option will change to "ass" at the next major
286 libavcodec version bump.
288 The current default is "ass_with_timings" for compatibility. This means that
289 all subtitles text decoders currently still output ASS with timings printed
290 as strings in the AVSubtitles.rects[N]->ass fields.
292 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
293 timing is limited to a 1/100 time base, so this is relevant for any subtitles
294 format needing a bigger one), ease timing adjustments, and prevents the need
295 of removing the timing from the decoded string yourself. This form is also
296 known as "the Matroska form". The timing information (start time, duration)
297 can be found in the AVSubtitles fields.

1494 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1495 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1551 For audio formats with fixed frame size, the last frame
1552 no longer needs to be padded with silence, libavcodec
1553 will handle this internally (effectively all encoders
1554 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2697 Remove the next field from AVFilter, this is not anymore required.
2699 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2700 Introduce the avfilter_next() function.
2702 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2703 Change the signature of avfilter_register() to make it return an
2704 int. This is required since now the registration operation may fail.
2706 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2707 Make the pixdesc.h API public.
2709 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2731 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2732 Add a pts field to AVSubtitle which gives the subtitle packet pts
2733 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2734 not work right without this.
2736 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2737 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2738 major version. Use AV_PKT_FLAG_KEY instead.
2740 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2741 av_lockmgr_register() can be used to register a callback function
2742 that lavc (and in the future, libraries that depend on lavc) can use
2743 to implement mutexes. The application should provide a callback function
2744 that implements the AV_LOCK_* operations described in avcodec.h.
2745 When the lock manager is registered, FFmpeg is guaranteed to behave
2746 correctly in a multi-threaded application.
2748 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2749 av_free_packet() is no longer an inline function. It is now exported.
2751 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2752 Please use NULL instead. This has been supported since r16506
2753 (lavf > 52.23.1, lavc > 52.10.0).
2755 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2756 The old decoding functions are deprecated, all new code should use the
2757 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2758 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2759 argument instead of a const uint8_t *buf / int buf_size pair.
2761 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2762 Introduce the av_fifo_space() function.
2764 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2765 Move AVPacket declaration from libavformat/avformat.h to
2766 libavcodec/avcodec.h.
2768 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2769 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2770 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2771 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2772 PIX_FMT_BGR32_1 are now macros.
2773 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2774 Re-sort the enum PixelFormat list accordingly.
2775 This change breaks API/ABI backward compatibility.
2777 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2778 Add the enum PixelFormat values:
2779 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2780 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2782 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2783 The Mersenne Twister PRNG implemented through the av_random* functions
2784 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2787 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2788 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2789 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2790 and av_fifo_realloc2.
2791 In addition, the order of the function arguments of av_fifo_generic_read
2792 was changed to match av_fifo_generic_write.
2793 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2794 applications, they may not use sizeof() or directly access members.
2796 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2797 Introduce a new metadata API (see av_metadata_get() and friends).
2798 The old API is now deprecated and should not be used anymore. This especially
2799 includes the following structure fields:
2800 - AVFormatContext.title
2801 - AVFormatContext.author
2802 - AVFormatContext.copyright
2803 - AVFormatContext.comment
2804 - AVFormatContext.album
2805 - AVFormatContext.year
2806 - AVFormatContext.track
2807 - AVFormatContext.genre
2810 - AVProgram.provider_name
