426 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
427 options. Introduce "listen_timeout" as replacement for the current "timeout"
428 option, and "user_agent" as replacement for "user-agent". Once the deprecation
429 is over, the old "timeout" option will be removed, and "stimeout" will be
430 renamed to "stimeout" (the "timeout" option will essentially change semantics).
432 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
433 Deprecate AVFormatContext filename field which had limited length, use the

446 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
447 If these are not called, network initialization and deinitialization is
448 automatic, and unlike in older versions, fully supported, unless libavformat
449 is linked to ancient GnuTLS and OpenSSL.

456 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
458 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
459 Deprecate the entire library. Merged years ago to provide compatibility
460 with Libav, it remained unmaintained by the FFmpeg project and duplicated
461 functionality provided by libswresample.
463 In order to improve consistency and reduce attack surface, it has been deprecated.
464 Users of this library are asked to migrate to libswresample, which, as well as
465 providing more functionality, is faster and has higher accuracy.
467 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

531 Add av_color_range_from_name(), av_color_primaries_from_name(),

567 DXVA2 and D3D11 hardware accelerated decoding now supports the new hwaccel API,
568 which can create the decoder context and allocate hardware frame automatically.
569 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
570 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

641 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
642 (via an entry named "rotate"). Use av_stream_get_side_data() with
643 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
644 av_display_rotation_get(). The same is done for muxing. Instead of adding a
645 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has

751 Decoders now export the frame timestamp as AVFrame.pts. It was
752 previously exported as AVFrame.pkt_pts, which is now deprecated.
754 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

805 Fix accidental ABI breakage in AVFilterContext.
806 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
808 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
809 compatible with lavfi>=6.47.100. Potentially also affects other users of
810 libavfilter if they are using one of the affected fields.

876 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
877 the reset of the ASS ReadOrder field on flush. This affects the content of
878 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
881 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
882 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
883 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
884 The default value for this option will change to "ass" at the next major
885 libavcodec version bump.
887 The current default is "ass_with_timings" for compatibility. This means that
888 all subtitles text decoders currently still output ASS with timings printed
889 as strings in the AVSubtitles.rects[N]->ass fields.
891 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
892 timing is limited to a 1/100 time base, so this is relevant for any subtitles
893 format needing a bigger one), ease timing adjustments, and prevents the need
894 of removing the timing from the decoded string yourself. This form is also
895 known as "the Matroska form". The timing information (start time, duration)
896 can be found in the AVSubtitles fields.

3301 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3302 Change the signature of avfilter_register() to make it return an
3303 int. This is required since now the registration operation may fail.
3305 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3306 Make the pixdesc.h API public.

3330 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3331 Add a pts field to AVSubtitle which gives the subtitle packet pts
3332 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3333 not work right without this.
3335 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3336 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3337 major version. Use AV_PKT_FLAG_KEY instead.
3339 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3340 av_lockmgr_register() can be used to register a callback function
3341 that lavc (and in the future, libraries that depend on lavc) can use
3342 to implement mutexes. The application should provide a callback function
3343 that implements the AV_LOCK_* operations described in avcodec.h.
3344 When the lock manager is registered, FFmpeg is guaranteed to behave
3345 correctly in a multi-threaded application.
3347 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3348 av_free_packet() is no longer an inline function. It is now exported.
3350 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3351 Please use NULL instead. This has been supported since r16506
3352 (lavf > 52.23.1, lavc > 52.10.0).
3354 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3355 The old decoding functions are deprecated, all new code should use the
3356 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3357 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3358 argument instead of a const uint8_t *buf / int buf_size pair.
3360 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3361 Introduce the av_fifo_space() function.
3363 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3364 Move AVPacket declaration from libavformat/avformat.h to
3365 libavcodec/avcodec.h.
3367 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3368 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3369 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3370 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3371 PIX_FMT_BGR32_1 are now macros.
3372 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3373 Re-sort the enum PixelFormat list accordingly.
3374 This change breaks API/ABI backward compatibility.
3376 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3377 Add the enum PixelFormat values:
3378 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3379 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3381 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3382 The Mersenne Twister PRNG implemented through the av_random* functions
3383 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3386 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3387 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3388 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3389 and av_fifo_realloc2.
3390 In addition, the order of the function arguments of av_fifo_generic_read
