2017-05-15 - xxxxxxxxxx - lavc 57.96.100 - avcodec.h
  VideoToolbox hardware-accelerated decoding now supports the new hwaccel API,
  which can create the decoder context and allocate hardware frames automatically.
  See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx.

2017-05-15 - xxxxxxxxxx - lavu 57.63.100 - hwcontext.h
  Add AV_HWDEVICE_TYPE_VIDEOTOOLBOX and implementation.

  Add AVCodecContext.apply_cropping to control whether cropping
  is handled by libavcodec or the caller.

2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
  The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
  the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
  set the Cuda device handle.

43
2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
44 45

50 51 52 53
  Add AV_FRAME_DATA_CONTENT_LIGHT_LEVEL value, av_content_light_metadata_alloc()
  and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata
  type to export content light level video properties.

  add av_fourcc_make_string() function and av_fourcc2str() macro to replace
  av_get_codec_tag_string() from lavc.

2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
67 68 69 70 71 72 73
  Deprecate that demuxers export the stream rotation angle in AVStream.metadata
  (via an entry named "rotate"). Use av_stream_get_side_data() with
  AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
  av_display_rotation_get(). The same is done for muxing. Instead of adding a
  "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
  to be added to the AVStream.

  AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the

180 181 182
  Note: When decoding, AVFrame.pts uses the stream/packet timebase,
  and not the codec timebase.

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

2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
  Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
231 232 233 234 235 236 237
  Fix accidental ABI breakage in AVFilterContext.
  ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.

  Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
  compatible with lavfi>=6.47.100. Potentially also affects other users of
  libavfilter if they are using one of the affected fields.

2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h
279 280
  Add AVStream.codecpar, deprecate AVStream.codec.

  f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
  e6053b3 / a806834 - Add av_get_audio_frame_duration2().
287

288
2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
289 290 291
  Add requirement to bitstream filtering API that returned packets with
  size == 0 and side_data_elems == 0 are to be skipped by the caller.

292
2016-03-04 - 9362973 - lavf 57.28.100
293 294
  Add protocol blacklisting API

295
2016-02-28 - 4dd4d53 - lavc 57.27.101
296 297 298 299 300
  Validate AVFrame returned by get_buffer2 to have required
  planes not NULL and unused planes set to NULL as crashes
  and buffer overflow are possible with certain streams if
  that is not the case.

301
2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
302 303 304 305 306
  "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
  the reset of the ASS ReadOrder field on flush. This affects the content of
  AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
  previous entry).

307
2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323
  Add a "sub_text_format" subtitles decoding option allowing the values "ass"
  (recommended) and "ass_with_timings" (not recommended, deprecated, default).
  The default value for this option will change to "ass" at the next major
  libavcodec version bump.

  The current default is "ass_with_timings" for compatibility. This means that
  all subtitles text decoders currently still output ASS with timings printed
  as strings in the AVSubtitles.rects[N]->ass fields.

  Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
  timing is limited to a 1/100 time base, so this is relevant for any subtitles
  format needing a bigger one), ease timing adjustments, and prevents the need
  of removing the timing from the decoded string yourself. This form is also
  known as "the Matroska form". The timing information (start time, duration)
  can be found in the AVSubtitles fields.

2762
  PKT_FLAG_KEY has been deprecated and will be dropped at the next

2766 2767 2768
  av_lockmgr_register() can be used to register a callback function
  that lavc (and in the future, libraries that depend on lavc) can use
  to implement mutexes. The application should provide a callback function
2769 2770 2771
  that implements the AV_LOCK_* operations described in avcodec.h.
  When the lock manager is registered, FFmpeg is guaranteed to behave
  correctly in a multi-threaded application.
2772

2773
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

2781 2782 2783 2784 2785
  The old decoding functions are deprecated, all new code should use the
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  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 2788

2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2794 2795 2796 2797 2798
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  PIX_FMT_BGR32_1 are now macros.
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2799
  Re-sort the enum PixelFormat list accordingly.
2800 2801
  This change breaks API/ABI backward compatibility.

2802

2803 2804 2805 2806

  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
2808 2809 2810 2811
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

2812
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
2813 2814 2815 2816
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  and av_fifo_realloc2.
  In addition, the order of the function arguments of av_fifo_generic_read
2817
  was changed to match av_fifo_generic_write.
2818 2819
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
2820

2821
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2822 2823
