396 options. Introduce "listen_timeout" as replacement for the current "timeout"
397 option, and "user_agent" as replacement for "user-agent". Once the deprecation
398 is over, the old "timeout" option will be removed, and "stimeout" will be
399 renamed to "stimeout" (the "timeout" option will essentially change semantics).
401 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
402 Deprecate AVFormatContext filename field which had limited length, use the

425 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
427 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
428 Deprecate the entire library. Merged years ago to provide compatibility
429 with Libav, it remained unmaintained by the FFmpeg project and duplicated
430 functionality provided by libswresample.
432 In order to improve consistency and reduce attack surface, it has been deprecated.
433 Users of this library are asked to migrate to libswresample, which, as well as
434 providing more functionality, is faster and has higher accuracy.

496 (avcodec_send_packet/avcodec_receive_frame) always work with reference
499 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
500 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

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

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

3267 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3268 Introduce the avfilter_next() function.
3270 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3271 Change the signature of avfilter_register() to make it return an
3272 int. This is required since now the registration operation may fail.
3274 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3275 Make the pixdesc.h API public.

3296 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3297 This is now an unsigned int instead of a signed int.
3299 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3300 Add a pts field to AVSubtitle which gives the subtitle packet pts
3301 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3302 not work right without this.
3304 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3305 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3306 major version. Use AV_PKT_FLAG_KEY instead.
3308 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3309 av_lockmgr_register() can be used to register a callback function
3310 that lavc (and in the future, libraries that depend on lavc) can use
3311 to implement mutexes. The application should provide a callback function
3312 that implements the AV_LOCK_* operations described in avcodec.h.
3313 When the lock manager is registered, FFmpeg is guaranteed to behave
3314 correctly in a multi-threaded application.
3316 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3317 av_free_packet() is no longer an inline function. It is now exported.
3319 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3320 Please use NULL instead. This has been supported since r16506
3321 (lavf > 52.23.1, lavc > 52.10.0).
3323 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3324 The old decoding functions are deprecated, all new code should use the
3325 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3326 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3327 argument instead of a const uint8_t *buf / int buf_size pair.
3329 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3330 Introduce the av_fifo_space() function.
3332 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3333 Move AVPacket declaration from libavformat/avformat.h to
3334 libavcodec/avcodec.h.
3336 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3337 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3338 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3339 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3340 PIX_FMT_BGR32_1 are now macros.
3341 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3342 Re-sort the enum PixelFormat list accordingly.
3343 This change breaks API/ABI backward compatibility.
3345 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3346 Add the enum PixelFormat values:
3347 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3348 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3350 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3351 The Mersenne Twister PRNG implemented through the av_random* functions
3352 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3355 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3356 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3357 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3358 and av_fifo_realloc2.
3359 In addition, the order of the function arguments of av_fifo_generic_read
3360 was changed to match av_fifo_generic_write.
3361 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3362 applications, they may not use sizeof() or directly access members.
3364 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3365 Introduce a new metadata API (see av_metadata_get() and friends).
3366 The old API is now deprecated and should not be used anymore. This especially
3367 includes the following structure fields:
3368 - AVFormatContext.title
3369 - AVFormatContext.author
3370 - AVFormatContext.copyright
3371 - AVFormatContext.comment
3372 - AVFormatContext.album
3373 - AVFormatContext.year
3374 - AVFormatContext.track
3375 - AVFormatContext.genre
3378 - AVProgram.provider_name
