399 2018-02-04 - ff46124b0d - lavf 58.8.100 - avformat.h
400 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
401 options. Introduce "listen_timeout" as replacement for the current "timeout"
402 option, and "user_agent" as replacement for "user-agent". Once the deprecation
403 is over, the old "timeout" option will be removed, and "stimeout" will be
404 renamed to "stimeout" (the "timeout" option will essentially change semantics).
406 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
407 Deprecate AVFormatContext filename field which had limited length, use the

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

430 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
432 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
433 Deprecate the entire library. Merged years ago to provide compatibility
434 with Libav, it remained unmaintained by the FFmpeg project and duplicated
435 functionality provided by libswresample.
437 In order to improve consistency and reduce attack surface, it has been deprecated.
438 Users of this library are asked to migrate to libswresample, which, as well as
439 providing more functionality, is faster and has higher accuracy.

499 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
500 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
501 (avcodec_send_packet/avcodec_receive_frame) always work with reference
504 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
505 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

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

850 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
851 the reset of the ASS ReadOrder field on flush. This affects the content of
852 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
855 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
856 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
857 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
858 The default value for this option will change to "ass" at the next major
859 libavcodec version bump.
861 The current default is "ass_with_timings" for compatibility. This means that
862 all subtitles text decoders currently still output ASS with timings printed
863 as strings in the AVSubtitles.rects[N]->ass fields.
865 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
866 timing is limited to a 1/100 time base, so this is relevant for any subtitles
867 format needing a bigger one), ease timing adjustments, and prevents the need
868 of removing the timing from the decoded string yourself. This form is also
869 known as "the Matroska form". The timing information (start time, duration)
870 can be found in the AVSubtitles fields.

3275 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3276 Change the signature of avfilter_register() to make it return an
3277 int. This is required since now the registration operation may fail.
3279 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3280 Make the pixdesc.h API public.

3301 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3302 This is now an unsigned int instead of a signed int.
3304 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3305 Add a pts field to AVSubtitle which gives the subtitle packet pts
3306 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3307 not work right without this.
3309 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3310 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3311 major version. Use AV_PKT_FLAG_KEY instead.
3313 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3314 av_lockmgr_register() can be used to register a callback function
3315 that lavc (and in the future, libraries that depend on lavc) can use
3316 to implement mutexes. The application should provide a callback function
3317 that implements the AV_LOCK_* operations described in avcodec.h.
3318 When the lock manager is registered, FFmpeg is guaranteed to behave
3319 correctly in a multi-threaded application.
3321 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3322 av_free_packet() is no longer an inline function. It is now exported.
3324 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3325 Please use NULL instead. This has been supported since r16506
3326 (lavf > 52.23.1, lavc > 52.10.0).
3328 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3329 The old decoding functions are deprecated, all new code should use the
3330 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3331 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3332 argument instead of a const uint8_t *buf / int buf_size pair.
3334 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3335 Introduce the av_fifo_space() function.
3337 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3338 Move AVPacket declaration from libavformat/avformat.h to
3339 libavcodec/avcodec.h.
3341 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3342 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3343 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3344 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3345 PIX_FMT_BGR32_1 are now macros.
3346 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3347 Re-sort the enum PixelFormat list accordingly.
3348 This change breaks API/ABI backward compatibility.
3350 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3351 Add the enum PixelFormat values:
3352 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3353 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3355 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3356 The Mersenne Twister PRNG implemented through the av_random* functions
3357 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3360 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3361 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3362 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3363 and av_fifo_realloc2.
3364 In addition, the order of the function arguments of av_fifo_generic_read
3365 was changed to match av_fifo_generic_write.
3366 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3367 applications, they may not use sizeof() or directly access members.
3369 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3370 Introduce a new metadata API (see av_metadata_get() and friends).
3371 The old API is now deprecated and should not be used anymore. This especially
3372 includes the following structure fields:
3373 - AVFormatContext.title
3374 - AVFormatContext.author
3375 - AVFormatContext.copyright
3376 - AVFormatContext.comment
3377 - AVFormatContext.album
3378 - AVFormatContext.year
3379 - AVFormatContext.track
3380 - AVFormatContext.genre
3383 - AVProgram.provider_name
