-  Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
-
-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
-  Fix accidental ABI breakage in AVFilterContext.
-  ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.

-  compatible with lavfi>=6.47.100. Potentially also affects other users of
-  libavfilter if they are using one of the affected fields.

-  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

-  1a70878 / 89923e4 hwcontext.h - Add a new installed header hwcontext.h with a new API
-                        for handling hwaccel frames.
-  6992276 / ad884d1 hwcontext_cuda.h - Add a new installed header hwcontext_cuda.h with
-                             CUDA-specific hwcontext definitions.
-  d779d8d / a001ce3 hwcontext_vdpau.h - Add a new installed header hwcontext_vdpau.h with
-                              VDPAU-specific hwcontext definitions.

-@item aac_pns
-Uses perceptual noise substitution to replace low entropy high frequency bands
-with imperceivable white noise during the decoding process. By default, it's
-enabled, but can be disabled for debugging purposes by using "disable".
-
-@item aac_tns
-Enables the use of a multitap FIR filter which spans through the high frequency
-bands to hide quantization noise during the encoding process and is reverted
-by the decoder. As well as decreasing unpleasant artifacts in the high range
-this also reduces the entropy in the high bands and allows for more bits to

-8 (limited range or full range), 10 or 12 bits, this makes it suitable for
-other tasks which require low overhead and low compression (like screen
-recording).
-
-@subsection Options
-
-@table @option
-
-@item b
-Sets target video bitrate. Usually that's around 1:6 of the uncompressed
-video bitrate (e.g. for 1920x1080 50fps yuv422p10 that's around 400Mbps). Higher
-values (close to the uncompressed bitrate) turn on lossless compression mode.
-
-@item field_order
-Enables field coding when set (e.g. to tt - top field first) for interlaced
-inputs. Should increase compression with interlaced content as it splits the
-fields and encodes each separately.
-
-@item wavelet_depth
-Sets the total amount of wavelet transforms to apply, between 1 and 5 (default).
-Lower values reduce compression and quality. Less capable decoders may not be
-able to handle values of @option{wavelet_depth} over 3.
-
-@item wavelet_type
-Sets the transform type. Currently only @var{5_3} (LeGall) and @var{9_7}
-(Deslauriers-Dubuc)
-are implemented, with 9_7 being the one with better compression and thus
-is the default.
-
-@item slice_width
-@item slice_height
-Sets the slice size for each slice. Larger values result in better compression.
-For compatibility with other more limited decoders use @option{slice_width} of
-32 and @option{slice_height} of 8.
-
-@item tolerance
-Sets the undershoot tolerance of the rate control system in percent. This is
-to prevent an expensive search from being run.
-
-@item qm
-Sets the quantization matrix preset to use by default or when @option{wavelet_depth}
-is set to 5
-@itemize @minus
-@item
-@var{default}
-Uses the default quantization matrix from the specifications, extended with
-values for the fifth level. This provides a good balance between keeping detail
-and omitting artifacts.
-
-@item
-@var{flat}
-Use a completely zeroed out quantization matrix. This increases PSNR but might
-reduce perception. Use in bogus benchmarks.
-
-@item
-@var{color}
-Reduces detail but attempts to preserve color at extremely low bitrates.

-This muxer computes and prints a cryptographic hash for each audio

-checks without having to individually do a binary comparison on each.
-
-By default audio frames are converted to signed 16-bit raw audio and

-of explicit conversions to other codecs can also be used. It uses the
-SHA-256 cryptographic hash function by default, but supports several
