398 Deprecate AVFormatContext filename field which had limited length, use the
399 new dynamically allocated url field instead.

421 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
423 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
424 Deprecate the entire library. Merged years ago to provide compatibility
425 with Libav, it remained unmaintained by the FFmpeg project and duplicated
426 functionality provided by libswresample.
428 In order to improve consistency and reduce attack surface, it has been deprecated.
429 Users of this library are asked to migrate to libswresample, which, as well as
430 providing more functionality, is faster and has higher accuracy.

490 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
491 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
492 (avcodec_send_packet/avcodec_receive_frame) always work with reference
495 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
496 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

766 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
767 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
769 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
770 Fix accidental ABI breakage in AVFilterContext.
771 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
773 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
774 compatible with lavfi>=6.47.100. Potentially also affects other users of
775 libavfilter if they are using one of the affected fields.

840 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
841 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
842 the reset of the ASS ReadOrder field on flush. This affects the content of
843 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
846 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
847 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
848 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
849 The default value for this option will change to "ass" at the next major
850 libavcodec version bump.
852 The current default is "ass_with_timings" for compatibility. This means that
853 all subtitles text decoders currently still output ASS with timings printed
854 as strings in the AVSubtitles.rects[N]->ass fields.
856 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
857 timing is limited to a 1/100 time base, so this is relevant for any subtitles
858 format needing a bigger one), ease timing adjustments, and prevents the need
859 of removing the timing from the decoded string yourself. This form is also
860 known as "the Matroska form". The timing information (start time, duration)
861 can be found in the AVSubtitles fields.

3263 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3264 Introduce the avfilter_next() function.
3266 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3267 Change the signature of avfilter_register() to make it return an
3268 int. This is required since now the registration operation may fail.
3270 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3271 Make the pixdesc.h API public.

3295 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3296 Add a pts field to AVSubtitle which gives the subtitle packet pts
3297 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3298 not work right without this.
3300 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3301 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3302 major version. Use AV_PKT_FLAG_KEY instead.
3304 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3305 av_lockmgr_register() can be used to register a callback function
3306 that lavc (and in the future, libraries that depend on lavc) can use
3307 to implement mutexes. The application should provide a callback function
3308 that implements the AV_LOCK_* operations described in avcodec.h.
3309 When the lock manager is registered, FFmpeg is guaranteed to behave
3310 correctly in a multi-threaded application.
3312 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3313 av_free_packet() is no longer an inline function. It is now exported.
3315 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3316 Please use NULL instead. This has been supported since r16506
3317 (lavf > 52.23.1, lavc > 52.10.0).
3319 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3320 The old decoding functions are deprecated, all new code should use the
3321 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3322 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3323 argument instead of a const uint8_t *buf / int buf_size pair.
3325 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3326 Introduce the av_fifo_space() function.
3328 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3329 Move AVPacket declaration from libavformat/avformat.h to
3330 libavcodec/avcodec.h.
3332 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3333 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3334 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3335 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3336 PIX_FMT_BGR32_1 are now macros.
3337 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3338 Re-sort the enum PixelFormat list accordingly.
3339 This change breaks API/ABI backward compatibility.
3341 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3342 Add the enum PixelFormat values:
3343 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3344 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3346 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3347 The Mersenne Twister PRNG implemented through the av_random* functions
3348 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3351 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3352 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3353 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3354 and av_fifo_realloc2.
3355 In addition, the order of the function arguments of av_fifo_generic_read
3356 was changed to match av_fifo_generic_write.
3357 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3358 applications, they may not use sizeof() or directly access members.
3360 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3361 Introduce a new metadata API (see av_metadata_get() and friends).
3362 The old API is now deprecated and should not be used anymore. This especially
3363 includes the following structure fields:
3364 - AVFormatContext.title
3365 - AVFormatContext.author
3366 - AVFormatContext.copyright
3367 - AVFormatContext.comment
3368 - AVFormatContext.album
3369 - AVFormatContext.year
3370 - AVFormatContext.track
3371 - AVFormatContext.genre
3374 - AVProgram.provider_name
