410 2018-02-04 - ff46124b0d - lavf 58.8.100 - avformat.h
411 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
412 options. Introduce "listen_timeout" as replacement for the current "timeout"
413 option, and "user_agent" as replacement for "user-agent". Once the deprecation
414 is over, the old "timeout" option will be removed, and "stimeout" will be
415 renamed to "stimeout" (the "timeout" option will essentially change semantics).
417 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
418 Deprecate AVFormatContext filename field which had limited length, use the

431 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
432 If these are not called, network initialization and deinitialization is
433 automatic, and unlike in older versions, fully supported, unless libavformat
434 is linked to ancient GnuTLS and OpenSSL.
436 2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h

441 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
443 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
444 Deprecate the entire library. Merged years ago to provide compatibility
445 with Libav, it remained unmaintained by the FFmpeg project and duplicated
446 functionality provided by libswresample.
448 In order to improve consistency and reduce attack surface, it has been deprecated.
449 Users of this library are asked to migrate to libswresample, which, as well as
450 providing more functionality, is faster and has higher accuracy.
452 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

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

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

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

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

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

3286 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3287 Change the signature of avfilter_register() to make it return an
3288 int. This is required since now the registration operation may fail.

3315 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3316 Add a pts field to AVSubtitle which gives the subtitle packet pts
3317 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3318 not work right without this.
3320 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3321 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3322 major version. Use AV_PKT_FLAG_KEY instead.
3324 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3325 av_lockmgr_register() can be used to register a callback function
3326 that lavc (and in the future, libraries that depend on lavc) can use
3327 to implement mutexes. The application should provide a callback function
3328 that implements the AV_LOCK_* operations described in avcodec.h.
3329 When the lock manager is registered, FFmpeg is guaranteed to behave
3330 correctly in a multi-threaded application.
3332 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3333 av_free_packet() is no longer an inline function. It is now exported.
3335 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3336 Please use NULL instead. This has been supported since r16506
3337 (lavf > 52.23.1, lavc > 52.10.0).
3339 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3340 The old decoding functions are deprecated, all new code should use the
3341 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3342 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3343 argument instead of a const uint8_t *buf / int buf_size pair.
3345 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3346 Introduce the av_fifo_space() function.
3348 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3349 Move AVPacket declaration from libavformat/avformat.h to
3350 libavcodec/avcodec.h.
3352 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3353 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3354 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3355 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3356 PIX_FMT_BGR32_1 are now macros.
3357 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3358 Re-sort the enum PixelFormat list accordingly.
3359 This change breaks API/ABI backward compatibility.
3361 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3362 Add the enum PixelFormat values:
3363 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3364 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3366 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3367 The Mersenne Twister PRNG implemented through the av_random* functions
3368 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3371 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3372 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3373 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3374 and av_fifo_realloc2.
3375 In addition, the order of the function arguments of av_fifo_generic_read
3376 was changed to match av_fifo_generic_write.
3377 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3378 applications, they may not use sizeof() or directly access members.
3380 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
