422 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
423 options. Introduce "listen_timeout" as replacement for the current "timeout"
424 option, and "user_agent" as replacement for "user-agent". Once the deprecation
425 is over, the old "timeout" option will be removed, and "stimeout" will be
426 renamed to "stimeout" (the "timeout" option will essentially change semantics).
428 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
429 Deprecate AVFormatContext filename field which had limited length, use the

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

452 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
454 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
455 Deprecate the entire library. Merged years ago to provide compatibility
456 with Libav, it remained unmaintained by the FFmpeg project and duplicated
457 functionality provided by libswresample.
459 In order to improve consistency and reduce attack surface, it has been deprecated.
460 Users of this library are asked to migrate to libswresample, which, as well as
461 providing more functionality, is faster and has higher accuracy.

521 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
522 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
523 (avcodec_send_packet/avcodec_receive_frame) always work with reference
526 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
527 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

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

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

3326 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3327 Add a pts field to AVSubtitle which gives the subtitle packet pts
3328 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3331 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3332 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3333 major version. Use AV_PKT_FLAG_KEY instead.
3335 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3336 av_lockmgr_register() can be used to register a callback function
3337 that lavc (and in the future, libraries that depend on lavc) can use
3338 to implement mutexes. The application should provide a callback function
3339 that implements the AV_LOCK_* operations described in avcodec.h.
3340 When the lock manager is registered, FFmpeg is guaranteed to behave
3341 correctly in a multi-threaded application.
3343 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3344 av_free_packet() is no longer an inline function. It is now exported.
3346 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3347 Please use NULL instead. This has been supported since r16506
3348 (lavf > 52.23.1, lavc > 52.10.0).
3350 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3351 The old decoding functions are deprecated, all new code should use the
3352 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3353 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3354 argument instead of a const uint8_t *buf / int buf_size pair.
3356 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3357 Introduce the av_fifo_space() function.
3359 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3360 Move AVPacket declaration from libavformat/avformat.h to
3361 libavcodec/avcodec.h.
3363 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3364 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3365 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3366 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3367 PIX_FMT_BGR32_1 are now macros.
3368 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3369 Re-sort the enum PixelFormat list accordingly.
3370 This change breaks API/ABI backward compatibility.
3372 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3373 Add the enum PixelFormat values:
3374 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3375 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3377 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3378 The Mersenne Twister PRNG implemented through the av_random* functions
3379 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3382 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3383 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3384 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3385 and av_fifo_realloc2.
3386 In addition, the order of the function arguments of av_fifo_generic_read
3387 was changed to match av_fifo_generic_write.
