APIchanges

Never assume the API of libav* to be stable unless at least 1 month has passed
since the last major version increase or the API was added.

The last version increases were:
libavcodec:    2015-08-28
libavdevice:   2015-08-28
libavfilter:   2015-08-28
libavformat:   2015-08-28
libavresample: 2015-08-28
libpostproc:   2015-08-28
libswresample: 2015-08-28
libswscale:    2015-08-28
libavutil:     2015-08-28

2017-09-28 - xxxxxxx - lavc 57.106.104 - avcodec.h
  Add AV_PKT_DATA_A53_CC packet side data, to export closed captions

2017-09-27 - xxxxxxx - lavu 55.77.101 / lavu 55.31.1 - frame.h

  which can create the decoder context and allocate hardware frame automatically.
  See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
  the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

2017-06-14 - xxxxxxx - lavu 55.66.100 - hwcontext.h
  av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination
  as its flags argument (which was previously unused).

2017-06-14 - xxxxxxx - lavc 57.99.100 - avcodec.h

  parameter type to size_t at next major bump.

2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h

  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.

2017-03-23 - 7e4ba776a2 - lavc 57.85.101 - avcodec.h
  vdpau hardware accelerated decoding now supports the new hwaccel API, which

  Add AVIO_SEEKABLE_TIME flag.

2017-03-21 - d682ae70b4 - lavf 57.66.105, lavc 57.83.101 - avformat.h, avcodec.h
  Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
  bump, and libavformat will behave as if it were always set.
  Deprecate av_packet_merge_side_data() and av_packet_split_side_data().

2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

  Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
  and projection-specific properties (bound_left, bound_top, bound_right,
  bound_bottom, padding) to AVSphericalMapping.

2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
  AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
  native decoder format. (The default value is not changed.)

  Remove requirement to use AVOption or accessors to access certain fields
  in AVFrame, AVCodecContext, and AVFormatContext that were previously

  previously exported as AVFrame.pkt_pts, which is now deprecated.

  Add trailing_padding to AVCodecContext to match the corresponding
  field in AVCodecParameters.

2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
  Add a new API for chained BSF filters and passthrough (null) BSF --
  av_bsf_list_alloc(), av_bsf_list_free(), av_bsf_list_append(),
  av_bsf_list_append2(), av_bsf_list_finalize(), av_bsf_list_parse_str()
  and av_bsf_get_null_filter().

2016-08-04 - 82a33c8 - lavf 57.46.100 - avformat.h
  Add av_get_frame_filename2()

2016-07-09 - 775389f / 90f469a - lavc 57.50.100 / 57.20.0 - avcodec.h

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

  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.

-------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------

  Add a new audio/video encoding and decoding API with decoupled input
  and output -- avcodec_send_packet(), avcodec_receive_frame(),

  Add a new bitstream filtering API working with AVPackets.
  Deprecate the old bitstream filtering API.

2016-04-14 - 8688d3a / 07a844f - lavfi 6.42.100 / 6.3.0 - avfilter.h
  Add AVFilterContext.hw_device_ctx.

2016-04-14 - 28abb21 / 551c677 - lavu 55.22.100 / 55.9.0 - hwcontext_vaapi.h

  Add AVStream.codecpar, deprecate AVStream.codec.

2016-04-02 - e8a9b64 - lavu 55.20.100 - base64.h
  Add AV_BASE64_DECODE_SIZE(x) macro.

2016-xx-xx - lavc 57.33.100 / 57.14.0 - avcodec.h
  f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
  e6053b3 / a806834 - Add av_get_audio_frame_duration2().

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

2016-03-04 - 9362973 - lavf 57.28.100
  Add protocol blacklisting API

2016-02-28 - 4dd4d53 - lavc 57.27.101
  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.

2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
  "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).

2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
  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.

2016-02-24 - 7e49cdd / 7b3214d0 - lavc 57.25.100 / 57.13.0 - avcodec.h
  Add AVCodecContext.hw_frames_ctx.
