398 options. Introduce "listen_timeout" as replacement for the current "timeout"
399 option, and "user_agent" as replacement for "user-agent". Once the deprecation
400 is over, the old "timeout" option will be removed, and "stimeout" will be
401 renamed to "stimeout" (the "timeout" option will essentially change semantics).
403 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
404 Deprecate AVFormatContext filename field which had limited length, use the
405 new dynamically allocated url field instead.

417 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
418 If these are not called, network initialization and deinitialization is
419 automatic, and unlike in older versions, fully supported, unless libavformat
420 is linked to ancient GnuTLS and OpenSSL.
422 2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h

426 2018-01-05 - 798dcf2432 - lavfi 7.11.101 - avfilter.h
427 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
429 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
430 Deprecate the entire library. Merged years ago to provide compatibility
431 with Libav, it remained unmaintained by the FFmpeg project and duplicated
432 functionality provided by libswresample.
434 In order to improve consistency and reduce attack surface, it has been deprecated.
435 Users of this library are asked to migrate to libswresample, which, as well as
436 providing more functionality, is faster and has higher accuracy.
438 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

496 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
497 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
498 (avcodec_send_packet/avcodec_receive_frame) always work with reference
501 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
502 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

612 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
613 (via an entry named "rotate"). Use av_stream_get_side_data() with
614 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
615 av_display_rotation_get(). The same is done for muxing. Instead of adding a
616 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
617 to be added to the AVStream.

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

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

847 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
848 the reset of the ASS ReadOrder field on flush. This affects the content of
849 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
852 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
853 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
854 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
855 The default value for this option will change to "ass" at the next major
856 libavcodec version bump.
858 The current default is "ass_with_timings" for compatibility. This means that
859 all subtitles text decoders currently still output ASS with timings printed
860 as strings in the AVSubtitles.rects[N]->ass fields.
862 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
863 timing is limited to a 1/100 time base, so this is relevant for any subtitles
864 format needing a bigger one), ease timing adjustments, and prevents the need
865 of removing the timing from the decoded string yourself. This form is also
866 known as "the Matroska form". The timing information (start time, duration)
867 can be found in the AVSubtitles fields.

3267 Remove the next field from AVFilter, this is not anymore required.
3269 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3270 Introduce the avfilter_next() function.
3272 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3273 Change the signature of avfilter_register() to make it return an
3274 int. This is required since now the registration operation may fail.
3276 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3277 Make the pixdesc.h API public.

3298 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3299 This is now an unsigned int instead of a signed int.
3301 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3302 Add a pts field to AVSubtitle which gives the subtitle packet pts
3303 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3304 not work right without this.
3306 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3307 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3308 major version. Use AV_PKT_FLAG_KEY instead.
3310 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3311 av_lockmgr_register() can be used to register a callback function
3312 that lavc (and in the future, libraries that depend on lavc) can use
3313 to implement mutexes. The application should provide a callback function
3314 that implements the AV_LOCK_* operations described in avcodec.h.
3315 When the lock manager is registered, FFmpeg is guaranteed to behave
3316 correctly in a multi-threaded application.
3318 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3319 av_free_packet() is no longer an inline function. It is now exported.
3321 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3322 Please use NULL instead. This has been supported since r16506
3323 (lavf > 52.23.1, lavc > 52.10.0).
3325 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3326 The old decoding functions are deprecated, all new code should use the
3327 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3328 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3329 argument instead of a const uint8_t *buf / int buf_size pair.
3331 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3332 Introduce the av_fifo_space() function.
3334 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3335 Move AVPacket declaration from libavformat/avformat.h to
3336 libavcodec/avcodec.h.
3338 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3339 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3340 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3341 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3342 PIX_FMT_BGR32_1 are now macros.
3343 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3344 Re-sort the enum PixelFormat list accordingly.
3345 This change breaks API/ABI backward compatibility.
3347 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3348 Add the enum PixelFormat values:
3349 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3350 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3352 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3353 The Mersenne Twister PRNG implemented through the av_random* functions
3354 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3357 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3358 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3359 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3360 and av_fifo_realloc2.
3361 In addition, the order of the function arguments of av_fifo_generic_read
3362 was changed to match av_fifo_generic_write.
3363 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3364 applications, they may not use sizeof() or directly access members.
3366 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3367 Introduce a new metadata API (see av_metadata_get() and friends).
3368 The old API is now deprecated and should not be used anymore. This especially
3369 includes the following structure fields:
3370 - AVFormatContext.title
3371 - AVFormatContext.author
3372 - AVFormatContext.copyright
3373 - AVFormatContext.comment
3374 - AVFormatContext.album
3375 - AVFormatContext.year
3376 - AVFormatContext.track
3377 - AVFormatContext.genre
3380 - AVProgram.provider_name
