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

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

460 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
462 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
463 Deprecate the entire library. Merged years ago to provide compatibility
464 with Libav, it remained unmaintained by the FFmpeg project and duplicated
465 functionality provided by libswresample.
467 In order to improve consistency and reduce attack surface, it has been deprecated.
468 Users of this library are asked to migrate to libswresample, which, as well as
469 providing more functionality, is faster and has higher accuracy.

529 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
530 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
531 (avcodec_send_packet/avcodec_receive_frame) always work with reference

535 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

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

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

3334 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3335 Add a pts field to AVSubtitle which gives the subtitle packet pts
3336 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3337 not work right without this.
3339 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3340 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3341 major version. Use AV_PKT_FLAG_KEY instead.
3343 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3344 av_lockmgr_register() can be used to register a callback function
3345 that lavc (and in the future, libraries that depend on lavc) can use
3346 to implement mutexes. The application should provide a callback function
3347 that implements the AV_LOCK_* operations described in avcodec.h.
3348 When the lock manager is registered, FFmpeg is guaranteed to behave
3349 correctly in a multi-threaded application.
3351 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3352 av_free_packet() is no longer an inline function. It is now exported.
3354 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3355 Please use NULL instead. This has been supported since r16506
3356 (lavf > 52.23.1, lavc > 52.10.0).
3358 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3359 The old decoding functions are deprecated, all new code should use the
3360 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3361 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3362 argument instead of a const uint8_t *buf / int buf_size pair.
3364 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3365 Introduce the av_fifo_space() function.

3368 Move AVPacket declaration from libavformat/avformat.h to
3369 libavcodec/avcodec.h.
3371 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3372 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3373 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3374 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3375 PIX_FMT_BGR32_1 are now macros.
3376 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3377 Re-sort the enum PixelFormat list accordingly.
3378 This change breaks API/ABI backward compatibility.
3380 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3381 Add the enum PixelFormat values:
3382 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3383 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3385 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3386 The Mersenne Twister PRNG implemented through the av_random* functions
3387 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

3391 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3392 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3393 and av_fifo_realloc2.
3394 In addition, the order of the function arguments of av_fifo_generic_read
3395 was changed to match av_fifo_generic_write.

3397 applications, they may not use sizeof() or directly access members.
