417 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
418 Deprecate the entire library. Merged years ago to provide compatibility
419 with Libav, it remained unmaintained by the FFmpeg project and duplicated
420 functionality provided by libswresample.
422 In order to improve consistency and reduce attack surface, it has been deprecated.
423 Users of this library are asked to migrate to libswresample, which, as well as
424 providing more functionality, is faster and has higher accuracy.

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

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

834 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
835 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
836 the reset of the ASS ReadOrder field on flush. This affects the content of
837 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
840 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
841 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
842 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
843 The default value for this option will change to "ass" at the next major
844 libavcodec version bump.
846 The current default is "ass_with_timings" for compatibility. This means that
847 all subtitles text decoders currently still output ASS with timings printed
848 as strings in the AVSubtitles.rects[N]->ass fields.
850 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
851 timing is limited to a 1/100 time base, so this is relevant for any subtitles
852 format needing a bigger one), ease timing adjustments, and prevents the need
853 of removing the timing from the decoded string yourself. This form is also
854 known as "the Matroska form". The timing information (start time, duration)
855 can be found in the AVSubtitles fields.

3257 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3258 Introduce the avfilter_next() function.
3260 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3261 Change the signature of avfilter_register() to make it return an
3262 int. This is required since now the registration operation may fail.
3264 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3265 Make the pixdesc.h API public.

3289 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3290 Add a pts field to AVSubtitle which gives the subtitle packet pts
3291 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3292 not work right without this.
3294 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3295 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3296 major version. Use AV_PKT_FLAG_KEY instead.
3298 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3299 av_lockmgr_register() can be used to register a callback function
3300 that lavc (and in the future, libraries that depend on lavc) can use
3301 to implement mutexes. The application should provide a callback function
3302 that implements the AV_LOCK_* operations described in avcodec.h.
3303 When the lock manager is registered, FFmpeg is guaranteed to behave
3304 correctly in a multi-threaded application.
3306 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3307 av_free_packet() is no longer an inline function. It is now exported.
3309 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3310 Please use NULL instead. This has been supported since r16506
3311 (lavf > 52.23.1, lavc > 52.10.0).
3313 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3314 The old decoding functions are deprecated, all new code should use the
3315 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3316 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3317 argument instead of a const uint8_t *buf / int buf_size pair.
3319 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3320 Introduce the av_fifo_space() function.
3322 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3323 Move AVPacket declaration from libavformat/avformat.h to
3324 libavcodec/avcodec.h.
3326 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3327 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3328 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3329 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3330 PIX_FMT_BGR32_1 are now macros.
3331 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3332 Re-sort the enum PixelFormat list accordingly.
3333 This change breaks API/ABI backward compatibility.
3335 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3336 Add the enum PixelFormat values:
3337 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3338 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3340 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3341 The Mersenne Twister PRNG implemented through the av_random* functions
3342 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3345 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3346 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3347 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3348 and av_fifo_realloc2.
3349 In addition, the order of the function arguments of av_fifo_generic_read
3350 was changed to match av_fifo_generic_write.
3351 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3352 applications, they may not use sizeof() or directly access members.
3354 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3355 Introduce a new metadata API (see av_metadata_get() and friends).
3356 The old API is now deprecated and should not be used anymore. This especially
3357 includes the following structure fields:
3358 - AVFormatContext.title
3359 - AVFormatContext.author
3360 - AVFormatContext.copyright
3361 - AVFormatContext.comment
3362 - AVFormatContext.album
3363 - AVFormatContext.year
3364 - AVFormatContext.track
3365 - AVFormatContext.genre
3368 - AVProgram.provider_name
