418 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
419 options. Introduce "listen_timeout" as replacement for the current "timeout"
420 option, and "user_agent" as replacement for "user-agent". Once the deprecation
421 is over, the old "timeout" option will be removed, and "stimeout" will be
422 renamed to "stimeout" (the "timeout" option will essentially change semantics).
424 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
425 Deprecate AVFormatContext filename field which had limited length, use the

438 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
439 If these are not called, network initialization and deinitialization is
440 automatic, and unlike in older versions, fully supported, unless libavformat
441 is linked to ancient GnuTLS and OpenSSL.
443 2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h

448 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
450 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
451 Deprecate the entire library. Merged years ago to provide compatibility
452 with Libav, it remained unmaintained by the FFmpeg project and duplicated
453 functionality provided by libswresample.
455 In order to improve consistency and reduce attack surface, it has been deprecated.
456 Users of this library are asked to migrate to libswresample, which, as well as
457 providing more functionality, is faster and has higher accuracy.
459 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

517 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
518 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
519 (avcodec_send_packet/avcodec_receive_frame) always work with reference
522 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
523 Add av_color_range_from_name(), av_color_primaries_from_name(),
524 av_color_transfer_from_name(), av_color_space_from_name(), and

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

633 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
634 (via an entry named "rotate"). Use av_stream_get_side_data() with
635 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
636 av_display_rotation_get(). The same is done for muxing. Instead of adding a
637 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
638 to be added to the AVStream.

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

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

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

3293 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3294 Change the signature of avfilter_register() to make it return an
3295 int. This is required since now the registration operation may fail.
3297 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3298 Make the pixdesc.h API public.

3322 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3323 Add a pts field to AVSubtitle which gives the subtitle packet pts
3324 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3325 not work right without this.
3327 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3328 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3329 major version. Use AV_PKT_FLAG_KEY instead.
3331 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3332 av_lockmgr_register() can be used to register a callback function
3333 that lavc (and in the future, libraries that depend on lavc) can use
3334 to implement mutexes. The application should provide a callback function
3335 that implements the AV_LOCK_* operations described in avcodec.h.
3336 When the lock manager is registered, FFmpeg is guaranteed to behave
3337 correctly in a multi-threaded application.
3339 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3340 av_free_packet() is no longer an inline function. It is now exported.
3342 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3343 Please use NULL instead. This has been supported since r16506
3344 (lavf > 52.23.1, lavc > 52.10.0).
3346 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3347 The old decoding functions are deprecated, all new code should use the
3348 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3349 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3350 argument instead of a const uint8_t *buf / int buf_size pair.
3352 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3353 Introduce the av_fifo_space() function.
3355 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3356 Move AVPacket declaration from libavformat/avformat.h to
3357 libavcodec/avcodec.h.
3359 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3360 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3361 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3362 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3363 PIX_FMT_BGR32_1 are now macros.
3364 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3365 Re-sort the enum PixelFormat list accordingly.
3366 This change breaks API/ABI backward compatibility.
3368 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3369 Add the enum PixelFormat values:
3370 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3371 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3373 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3374 The Mersenne Twister PRNG implemented through the av_random* functions
3375 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3378 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3379 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3380 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3381 and av_fifo_realloc2.
3382 In addition, the order of the function arguments of av_fifo_generic_read
3383 was changed to match av_fifo_generic_write.
3384 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3385 applications, they may not use sizeof() or directly access members.
