16 API changes, most recent first:
18 2017-05-15 - xxxxxxxxxx - lavc 57.96.100 - avcodec.h
19 VideoToolbox hardware-accelerated decoding now supports the new hwaccel API,
20 which can create the decoder context and allocate hardware frames automatically.
21 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx.
23 2017-05-15 - xxxxxxxxxx - lavu 57.63.100 - hwcontext.h
24 Add AV_HWDEVICE_TYPE_VIDEOTOOLBOX and implementation.
26 2017-xx-xx - xxxxxxx - lavc 57.95.100 / 57.31.0 - avcodec.h
27 Add AVCodecContext.apply_cropping to control whether cropping
28 is handled by libavcodec or the caller.
30 2017-xx-xx - xxxxxxx - lavu 55.62.100 / 55.30.0 - frame.h
31 Add AVFrame.crop_left/right/top/bottom fields for attaching cropping
32 information to video frames.
34 2017-xx-xx - xxxxxxxxxx
35 Change av_sha_update(), av_sha512_update() and av_md5_sum()/av_md5_update() length
36 parameter type to size_t at next major bump.
38 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
39 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
40 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
41 set the Cuda device handle.
43 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
46 2016-04-06 - 157e57a181 - lavc 57.92.100 - avcodec.h
47 Add AV_PKT_DATA_CONTENT_LIGHT_LEVEL packet side data.
49 2016-04-06 - b378f5bd64 - lavu 55.60.100 - mastering_display_metadata.h
50 Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
51 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
52 type to export content light level video properties.

66 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
67 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
68 (via an entry named "rotate"). Use av_stream_get_side_data() with
69 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
70 av_display_rotation_get(). The same is done for muxing. Instead of adding a
71 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
72 to be added to the AVStream.

87 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
88 bump, and libavformat will behave as if it were always set.
89 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
91 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

104 and projection-specific properties (bound_left, bound_top, bound_right,
105 bound_bottom, padding) to AVSphericalMapping.
107 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
108 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
109 native decoder format. (The default value is not changed.)
111 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
112 Remove requirement to use AVOption or accessors to access certain fields
113 in AVFrame, AVCodecContext, and AVFormatContext that were previously
114 documented as "no direct access" allowed.
116 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
117 Add AVCodecContext.hw_device_ctx.

177 Decoders now export the frame timestamp as AVFrame.pts. It was
178 previously exported as AVFrame.pkt_pts, which is now deprecated.
180 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
181 and not the codec timebase.

222 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
223 Moved codecpar field from AVStream to the end of the struct, so that
224 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
226 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
227 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

231 Fix accidental ABI breakage in AVFilterContext.
232 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
234 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
235 compatible with lavfi>=6.47.100. Potentially also affects other users of
236 libavfilter if they are using one of the affected fields.

286 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
288 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
289 Add requirement to bitstream filtering API that returned packets with
290 size == 0 and side_data_elems == 0 are to be skipped by the caller.
292 2016-03-04 - 9362973 - lavf 57.28.100
293 Add protocol blacklisting API
295 2016-02-28 - 4dd4d53 - lavc 57.27.101
296 Validate AVFrame returned by get_buffer2 to have required
297 planes not NULL and unused planes set to NULL as crashes
298 and buffer overflow are possible with certain streams if
299 that is not the case.
301 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
302 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
303 the reset of the ASS ReadOrder field on flush. This affects the content of
304 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
307 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
308 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
309 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
310 The default value for this option will change to "ass" at the next major
311 libavcodec version bump.
313 The current default is "ass_with_timings" for compatibility. This means that
314 all subtitles text decoders currently still output ASS with timings printed
315 as strings in the AVSubtitles.rects[N]->ass fields.
317 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
318 timing is limited to a 1/100 time base, so this is relevant for any subtitles
319 format needing a bigger one), ease timing adjustments, and prevents the need
320 of removing the timing from the decoded string yourself. This form is also
321 known as "the Matroska form". The timing information (start time, duration)
322 can be found in the AVSubtitles fields.

1576 For audio formats with fixed frame size, the last frame
1577 no longer needs to be padded with silence, libavcodec
1578 will handle this internally (effectively all encoders
1579 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2725 Introduce the avfilter_next() function.
2727 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2728 Change the signature of avfilter_register() to make it return an
2729 int. This is required since now the registration operation may fail.

2761 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2762 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2763 major version. Use AV_PKT_FLAG_KEY instead.
2765 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2766 av_lockmgr_register() can be used to register a callback function
2767 that lavc (and in the future, libraries that depend on lavc) can use
2768 to implement mutexes. The application should provide a callback function
2769 that implements the AV_LOCK_* operations described in avcodec.h.
2770 When the lock manager is registered, FFmpeg is guaranteed to behave
2771 correctly in a multi-threaded application.
2773 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2774 av_free_packet() is no longer an inline function. It is now exported.
2776 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2777 Please use NULL instead. This has been supported since r16506
2778 (lavf > 52.23.1, lavc > 52.10.0).
2780 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2781 The old decoding functions are deprecated, all new code should use the
2782 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2783 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2784 argument instead of a const uint8_t *buf / int buf_size pair.
2786 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2787 Introduce the av_fifo_space() function.
2789 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2790 Move AVPacket declaration from libavformat/avformat.h to
2791 libavcodec/avcodec.h.
2793 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2794 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2795 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2796 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2797 PIX_FMT_BGR32_1 are now macros.
2798 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2799 Re-sort the enum PixelFormat list accordingly.
2800 This change breaks API/ABI backward compatibility.
2802 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2803 Add the enum PixelFormat values:
2804 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2805 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2807 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2808 The Mersenne Twister PRNG implemented through the av_random* functions
2809 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2812 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2813 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2814 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2815 and av_fifo_realloc2.
2816 In addition, the order of the function arguments of av_fifo_generic_read
2817 was changed to match av_fifo_generic_write.
2818 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2819 applications, they may not use sizeof() or directly access members.
2821 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2822 Introduce a new metadata API (see av_metadata_get() and friends).
2823 The old API is now deprecated and should not be used anymore. This especially
2824 includes the following structure fields:
2825 - AVFormatContext.title
2826 - AVFormatContext.author
2827 - AVFormatContext.copyright
2828 - AVFormatContext.comment
2829 - AVFormatContext.album
2830 - AVFormatContext.year
2831 - AVFormatContext.track
2832 - AVFormatContext.genre
2835 - AVProgram.provider_name
