option, and "user_agent" as replacement for "user-agent". Once the deprecation

2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h

with Libav, it remained unmaintained by the FFmpeg project and duplicated
functionality provided by libswresample.

providing more functionality, is faster and has higher accuracy.

parameter type to size_t at next major bump.
2017-05-05 - c0f17a905f - 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.

(via an entry named "rotate"). Use av_stream_get_side_data() with
AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

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.

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

libavfilter if they are using one of the affected fields.

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.
