433 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
434 options. Introduce "listen_timeout" as replacement for the current "timeout"
435 option, and "user_agent" as replacement for "user-agent". Once the deprecation
436 is over, the old "timeout" option will be removed, and "stimeout" will be
437 renamed to "stimeout" (the "timeout" option will essentially change semantics).
439 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
440 Deprecate AVFormatContext filename field which had limited length, use the

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

463 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
465 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
466 Deprecate the entire library. Merged years ago to provide compatibility
467 with Libav, it remained unmaintained by the FFmpeg project and duplicated
468 functionality provided by libswresample.
470 In order to improve consistency and reduce attack surface, it has been deprecated.
471 Users of this library are asked to migrate to libswresample, which, as well as
472 providing more functionality, is faster and has higher accuracy.

532 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
533 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
534 (avcodec_send_packet/avcodec_receive_frame) always work with reference
537 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
538 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

648 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
649 (via an entry named "rotate"). Use av_stream_get_side_data() with
650 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
651 av_display_rotation_get(). The same is done for muxing. Instead of adding a
652 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
653 to be added to the AVStream.

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

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

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

3337 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3338 Add a pts field to AVSubtitle which gives the subtitle packet pts
3339 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3340 not work right without this.
3342 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3343 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3344 major version. Use AV_PKT_FLAG_KEY instead.
3346 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3347 av_lockmgr_register() can be used to register a callback function
3348 that lavc (and in the future, libraries that depend on lavc) can use
3349 to implement mutexes. The application should provide a callback function
3350 that implements the AV_LOCK_* operations described in avcodec.h.
3351 When the lock manager is registered, FFmpeg is guaranteed to behave
3352 correctly in a multi-threaded application.
3354 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3355 av_free_packet() is no longer an inline function. It is now exported.
3357 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3358 Please use NULL instead. This has been supported since r16506
3359 (lavf > 52.23.1, lavc > 52.10.0).
3361 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3362 The old decoding functions are deprecated, all new code should use the
3363 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3364 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3365 argument instead of a const uint8_t *buf / int buf_size pair.
3367 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3368 Introduce the av_fifo_space() function.

3371 Move AVPacket declaration from libavformat/avformat.h to
3372 libavcodec/avcodec.h.
3374 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3375 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3376 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3377 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3378 PIX_FMT_BGR32_1 are now macros.
3379 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3380 Re-sort the enum PixelFormat list accordingly.
3381 This change breaks API/ABI backward compatibility.
3383 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3384 Add the enum PixelFormat values:

3388 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3389 The Mersenne Twister PRNG implemented through the av_random* functions
3390 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3393 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3394 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3395 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3396 and av_fifo_realloc2.
3397 In addition, the order of the function arguments of av_fifo_generic_read
3398 was changed to match av_fifo_generic_write.
3399 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3400 applications, they may not use sizeof() or directly access members.
