410 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
411 options. Introduce "listen_timeout" as replacement for the current "timeout"
412 option, and "user_agent" as replacement for "user-agent". Once the deprecation
413 is over, the old "timeout" option will be removed, and "stimeout" will be
414 renamed to "stimeout" (the "timeout" option will essentially change semantics).
416 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
417 Deprecate AVFormatContext filename field which had limited length, use the

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

440 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
442 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
443 Deprecate the entire library. Merged years ago to provide compatibility
444 with Libav, it remained unmaintained by the FFmpeg project and duplicated
445 functionality provided by libswresample.
447 In order to improve consistency and reduce attack surface, it has been deprecated.
448 Users of this library are asked to migrate to libswresample, which, as well as
449 providing more functionality, is faster and has higher accuracy.

509 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
510 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
511 (avcodec_send_packet/avcodec_receive_frame) always work with reference
514 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
515 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

625 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
626 (via an entry named "rotate"). Use av_stream_get_side_data() with
627 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
628 av_display_rotation_get(). The same is done for muxing. Instead of adding a
629 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
630 to be added to the AVStream.

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

857 that is not the case.
859 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
860 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
861 the reset of the ASS ReadOrder field on flush. This affects the content of
862 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
865 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
866 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
867 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
868 The default value for this option will change to "ass" at the next major
869 libavcodec version bump.
871 The current default is "ass_with_timings" for compatibility. This means that
872 all subtitles text decoders currently still output ASS with timings printed
873 as strings in the AVSubtitles.rects[N]->ass fields.
875 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
876 timing is limited to a 1/100 time base, so this is relevant for any subtitles
877 format needing a bigger one), ease timing adjustments, and prevents the need
878 of removing the timing from the decoded string yourself. This form is also
879 known as "the Matroska form". The timing information (start time, duration)
880 can be found in the AVSubtitles fields.

3285 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3286 Change the signature of avfilter_register() to make it return an
3287 int. This is required since now the registration operation may fail.
3289 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3290 Make the pixdesc.h API public.

3311 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3312 This is now an unsigned int instead of a signed int.
3314 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3315 Add a pts field to AVSubtitle which gives the subtitle packet pts
3316 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3317 not work right without this.
3319 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3320 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3321 major version. Use AV_PKT_FLAG_KEY instead.
3323 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3324 av_lockmgr_register() can be used to register a callback function
3325 that lavc (and in the future, libraries that depend on lavc) can use
3326 to implement mutexes. The application should provide a callback function
3327 that implements the AV_LOCK_* operations described in avcodec.h.
3328 When the lock manager is registered, FFmpeg is guaranteed to behave
3329 correctly in a multi-threaded application.
3331 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3332 av_free_packet() is no longer an inline function. It is now exported.
3334 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3335 Please use NULL instead. This has been supported since r16506
3336 (lavf > 52.23.1, lavc > 52.10.0).
3338 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3339 The old decoding functions are deprecated, all new code should use the
3340 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3341 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3342 argument instead of a const uint8_t *buf / int buf_size pair.
3344 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3345 Introduce the av_fifo_space() function.
3347 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3348 Move AVPacket declaration from libavformat/avformat.h to
3349 libavcodec/avcodec.h.
3351 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3352 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3353 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3354 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3355 PIX_FMT_BGR32_1 are now macros.
3356 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3357 Re-sort the enum PixelFormat list accordingly.
3358 This change breaks API/ABI backward compatibility.
3360 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3361 Add the enum PixelFormat values:
3362 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3363 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3365 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3366 The Mersenne Twister PRNG implemented through the av_random* functions
3367 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3370 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3371 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3372 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3373 and av_fifo_realloc2.
3374 In addition, the order of the function arguments of av_fifo_generic_read
3375 was changed to match av_fifo_generic_write.
3376 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3377 applications, they may not use sizeof() or directly access members.
3379 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3380 Introduce a new metadata API (see av_metadata_get() and friends).
3381 The old API is now deprecated and should not be used anymore. This especially
3382 includes the following structure fields:
3383 - AVFormatContext.title
3384 - AVFormatContext.author
3385 - AVFormatContext.copyright
3386 - AVFormatContext.comment
3387 - AVFormatContext.album
3388 - AVFormatContext.year
3389 - AVFormatContext.track
3390 - AVFormatContext.genre
3393 - AVProgram.provider_name
