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

automatic, and unlike in older versions, fully supported, unless libavformat
is linked to ancient GnuTLS and OpenSSL.
2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h

2018-01-05 - 798dcf2432 - lavfi 7.11.101 - avfilter.h
Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
Deprecate the entire library. Merged years ago to provide compatibility
with Libav, it remained unmaintained by the FFmpeg project and duplicated
functionality provided by libswresample.
In order to improve consistency and reduce attack surface, it has been deprecated.
Users of this library are asked to migrate to libswresample, which, as well as
providing more functionality, is faster and has higher accuracy.
2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h
Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
support enabled to get basic thread-safety (which is the default build
configuration).

the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.
2017-06-27 - 3303511f33 - lavu 56.67.100 - hwcontext.h
Add AV_HWDEVICE_TYPE_D3D11VA and AV_PIX_FMT_D3D11.

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
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.

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_PIX_FMT_FLAG_BAYER pixel format flag.
2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
Deprecate AVFilterGraph.resample_lavr_opts
It's never been used by avfilter nor passed to anything.
2017-02-10 - 1b7ffddb3a - lavu 55.48.100 / 55.33.0 - spherical.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

Remove requirement to use AVOption or accessors to access certain fields
in AVFrame, AVCodecContext, and AVFormatContext that were previously
documented as "no direct access" allowed.
2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
Add AVCodecContext.hw_device_ctx.

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.

CodecID name.

Make avfilter_get_video_buffer() recursive and add the w and h
parameters to it.
2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
Add w and h fields to AVFilterPic.
2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
This is now an unsigned int instead of a signed int.
2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
Add a pts field to AVSubtitle which gives the subtitle packet pts
in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
not work right without this.
2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
PKT_FLAG_KEY has been deprecated and will be dropped at the next
major version. Use AV_PKT_FLAG_KEY instead.
2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
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
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.
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
av_free_packet() is no longer an inline function. It is now exported.
2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
Please use NULL instead. This has been supported since r16506
(lavf > 52.23.1, lavc > 52.10.0).
2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
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.
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
Introduce the av_fifo_space() function.
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
Move AVPacket declaration from libavformat/avformat.h to
libavcodec/avcodec.h.
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
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.
Re-sort the enum PixelFormat list accordingly.
This change breaks API/ABI backward compatibility.
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
Add the enum PixelFormat values:
PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
The Mersenne Twister PRNG implemented through the av_random* functions
was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
instead.
2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
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
was changed to match av_fifo_generic_write.
The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
applications, they may not use sizeof() or directly access members.
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
Introduce a new metadata API (see av_metadata_get() and friends).
The old API is now deprecated and should not be used anymore. This especially
includes the following structure fields:
- AVFormatContext.title
- AVFormatContext.author
- AVFormatContext.copyright
- AVFormatContext.comment
- AVFormatContext.album
- AVFormatContext.year
- AVFormatContext.track
- AVFormatContext.genre
- AVStream.language
- AVStream.filename
- AVProgram.provider_name
- AVProgram.name
- AVChapter.title
