412 2018-02-04 - ff46124b0d - lavf 58.8.100 - avformat.h
413 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
414 options. Introduce "listen_timeout" as replacement for the current "timeout"
415 option, and "user_agent" as replacement for "user-agent". Once the deprecation
416 is over, the old "timeout" option will be removed, and "stimeout" will be
417 renamed to "stimeout" (the "timeout" option will essentially change semantics).
419 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
420 Deprecate AVFormatContext filename field which had limited length, use the

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

443 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
445 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
446 Deprecate the entire library. Merged years ago to provide compatibility
447 with Libav, it remained unmaintained by the FFmpeg project and duplicated
448 functionality provided by libswresample.
450 In order to improve consistency and reduce attack surface, it has been deprecated.
451 Users of this library are asked to migrate to libswresample, which, as well as
452 providing more functionality, is faster and has higher accuracy.
454 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

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

555 which can create the decoder context and allocate hardware frame automatically.
556 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
557 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

628 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
629 (via an entry named "rotate"). Use av_stream_get_side_data() with
630 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

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

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

3288 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3289 Change the signature of avfilter_register() to make it return an
3290 int. This is required since now the registration operation may fail.

3317 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3318 Add a pts field to AVSubtitle which gives the subtitle packet pts
3319 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3320 not work right without this.
3322 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3323 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3324 major version. Use AV_PKT_FLAG_KEY instead.
3326 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3327 av_lockmgr_register() can be used to register a callback function
3328 that lavc (and in the future, libraries that depend on lavc) can use
3329 to implement mutexes. The application should provide a callback function
3330 that implements the AV_LOCK_* operations described in avcodec.h.
3331 When the lock manager is registered, FFmpeg is guaranteed to behave
3332 correctly in a multi-threaded application.
3334 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3335 av_free_packet() is no longer an inline function. It is now exported.
3337 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3338 Please use NULL instead. This has been supported since r16506
3339 (lavf > 52.23.1, lavc > 52.10.0).
3341 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3342 The old decoding functions are deprecated, all new code should use the
3343 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3344 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3345 argument instead of a const uint8_t *buf / int buf_size pair.
3347 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3348 Introduce the av_fifo_space() function.
3350 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3351 Move AVPacket declaration from libavformat/avformat.h to
3352 libavcodec/avcodec.h.
3354 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3355 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3356 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3357 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3358 PIX_FMT_BGR32_1 are now macros.
3359 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3360 Re-sort the enum PixelFormat list accordingly.
3361 This change breaks API/ABI backward compatibility.
3363 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3364 Add the enum PixelFormat values:
3365 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3366 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3368 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3369 The Mersenne Twister PRNG implemented through the av_random* functions
3370 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3373 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3374 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3375 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3376 and av_fifo_realloc2.
3377 In addition, the order of the function arguments of av_fifo_generic_read
3378 was changed to match av_fifo_generic_write.
3379 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3380 applications, they may not use sizeof() or directly access members.
