16 API changes, most recent first:
18 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
19 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
20 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
21 set the Cuda device handle.
23 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
26 2016-04-06 - 157e57a181 - lavc 57.92.100 - avcodec.h
27 Add AV_PKT_DATA_CONTENT_LIGHT_LEVEL packet side data.
29 2016-04-06 - b378f5bd64 - lavu 55.60.100 - mastering_display_metadata.h
30 Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
31 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
32 type to export content light level video properties.

35 Add av_spherical_projection_name().
36 Add av_spherical_from_name().

39 Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
40 Add av_hwframe_ctx_create_derived().
42 2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
43 add av_fourcc_make_string() function and av_fourcc2str() macro to replace
44 av_get_codec_tag_string() from lavc.
46 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
47 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
48 (via an entry named "rotate"). Use av_stream_get_side_data() with
49 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
50 av_display_rotation_get(). The same is done for muxing. Instead of adding a
51 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
52 to be added to the AVStream.
54 2017-03-23 - 7e4ba776a2 - lavc 57.85.101 - avcodec.h

67 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
68 bump, and libavformat will behave as if it were always set.
69 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
71 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

85 bound_bottom, padding) to AVSphericalMapping.
87 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
88 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
89 native decoder format. (The default value is not changed.)
91 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
92 Remove requirement to use AVOption or accessors to access certain fields
93 in AVFrame, AVCodecContext, and AVFormatContext that were previously
94 documented as "no direct access" allowed.
96 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
97 Add AVCodecContext.hw_device_ctx.

112 Deprecate struct vaapi_context and the vaapi.h installed header.
113 Callers should set AVCodecContext.hw_frames_ctx instead.
115 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
116 Add av_buffersink_get_*() functions.

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

202 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
203 Moved codecpar field from AVStream to the end of the struct, so that
204 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
206 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
207 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

210 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
211 Fix accidental ABI breakage in AVFilterContext.
212 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
214 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
215 compatible with lavfi>=6.47.100. Potentially also affects other users of
216 libavfilter if they are using one of the affected fields.

265 f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
266 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
268 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
269 Add requirement to bitstream filtering API that returned packets with
270 size == 0 and side_data_elems == 0 are to be skipped by the caller.
272 2016-03-04 - 9362973 - lavf 57.28.100
273 Add protocol blacklisting API
275 2016-02-28 - 4dd4d53 - lavc 57.27.101
276 Validate AVFrame returned by get_buffer2 to have required
277 planes not NULL and unused planes set to NULL as crashes
278 and buffer overflow are possible with certain streams if
279 that is not the case.
281 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
282 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
283 the reset of the ASS ReadOrder field on flush. This affects the content of
284 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
287 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
288 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
289 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
290 The default value for this option will change to "ass" at the next major
291 libavcodec version bump.
293 The current default is "ass_with_timings" for compatibility. This means that
294 all subtitles text decoders currently still output ASS with timings printed
295 as strings in the AVSubtitles.rects[N]->ass fields.
297 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
298 timing is limited to a 1/100 time base, so this is relevant for any subtitles
299 format needing a bigger one), ease timing adjustments, and prevents the need
300 of removing the timing from the decoded string yourself. This form is also
301 known as "the Matroska form". The timing information (start time, duration)
302 can be found in the AVSubtitles fields.

1556 For audio formats with fixed frame size, the last frame
1557 no longer needs to be padded with silence, libavcodec
1558 will handle this internally (effectively all encoders
1559 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2741 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2742 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2743 major version. Use AV_PKT_FLAG_KEY instead.
2745 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2746 av_lockmgr_register() can be used to register a callback function
2747 that lavc (and in the future, libraries that depend on lavc) can use
2748 to implement mutexes. The application should provide a callback function
2749 that implements the AV_LOCK_* operations described in avcodec.h.
2750 When the lock manager is registered, FFmpeg is guaranteed to behave
2751 correctly in a multi-threaded application.
2753 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2754 av_free_packet() is no longer an inline function. It is now exported.
2756 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2757 Please use NULL instead. This has been supported since r16506
2758 (lavf > 52.23.1, lavc > 52.10.0).
2760 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2761 The old decoding functions are deprecated, all new code should use the
2762 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2763 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2764 argument instead of a const uint8_t *buf / int buf_size pair.
2766 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2767 Introduce the av_fifo_space() function.
2769 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2770 Move AVPacket declaration from libavformat/avformat.h to
2771 libavcodec/avcodec.h.
2773 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2774 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2775 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2776 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2777 PIX_FMT_BGR32_1 are now macros.
2778 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2779 Re-sort the enum PixelFormat list accordingly.
2780 This change breaks API/ABI backward compatibility.
2782 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2783 Add the enum PixelFormat values:
2784 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2785 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2787 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2788 The Mersenne Twister PRNG implemented through the av_random* functions
2789 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2792 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2793 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2794 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2795 and av_fifo_realloc2.
2796 In addition, the order of the function arguments of av_fifo_generic_read
2797 was changed to match av_fifo_generic_write.
2798 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2799 applications, they may not use sizeof() or directly access members.
2801 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2802 Introduce a new metadata API (see av_metadata_get() and friends).
2803 The old API is now deprecated and should not be used anymore. This especially
2804 includes the following structure fields:
2805 - AVFormatContext.title
2806 - AVFormatContext.author
2807 - AVFormatContext.copyright
2808 - AVFormatContext.comment
2809 - AVFormatContext.album
2810 - AVFormatContext.year
2811 - AVFormatContext.track
2812 - AVFormatContext.genre
2815 - AVProgram.provider_name
