402 Deprecate the entire library. Merged years ago to provide compatibility
403 with Libav, it remained unmaintained by the FFmpeg project and duplicated
404 functionality provided by libswresample.
406 In order to improve consistency and reduce attack surface, it has been deprecated.
407 Users of this library are asked to migrate to libswresample, which, as well as
408 providing more functionality, is faster and has higher accuracy.

749 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
751 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be

819 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
820 the reset of the ASS ReadOrder field on flush. This affects the content of
821 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
824 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
825 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
826 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
827 The default value for this option will change to "ass" at the next major
828 libavcodec version bump.
830 The current default is "ass_with_timings" for compatibility. This means that
831 all subtitles text decoders currently still output ASS with timings printed
832 as strings in the AVSubtitles.rects[N]->ass fields.
834 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
835 timing is limited to a 1/100 time base, so this is relevant for any subtitles
836 format needing a bigger one), ease timing adjustments, and prevents the need
837 of removing the timing from the decoded string yourself. This form is also
838 known as "the Matroska form". The timing information (start time, duration)
839 can be found in the AVSubtitles fields.

3241 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3242 Introduce the avfilter_next() function.
3244 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3245 Change the signature of avfilter_register() to make it return an
3246 int. This is required since now the registration operation may fail.
3248 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3249 Make the pixdesc.h API public.
3251 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3268 Add w and h fields to AVFilterPic.
3270 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3271 This is now an unsigned int instead of a signed int.
3273 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3274 Add a pts field to AVSubtitle which gives the subtitle packet pts
3275 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3276 not work right without this.
3278 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3279 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3280 major version. Use AV_PKT_FLAG_KEY instead.
3282 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3283 av_lockmgr_register() can be used to register a callback function
3284 that lavc (and in the future, libraries that depend on lavc) can use
3285 to implement mutexes. The application should provide a callback function
3286 that implements the AV_LOCK_* operations described in avcodec.h.
3287 When the lock manager is registered, FFmpeg is guaranteed to behave
3288 correctly in a multi-threaded application.
3290 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3291 av_free_packet() is no longer an inline function. It is now exported.
3293 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3294 Please use NULL instead. This has been supported since r16506
3295 (lavf > 52.23.1, lavc > 52.10.0).
3297 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3298 The old decoding functions are deprecated, all new code should use the
3299 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3300 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3301 argument instead of a const uint8_t *buf / int buf_size pair.
3303 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3304 Introduce the av_fifo_space() function.
3306 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3307 Move AVPacket declaration from libavformat/avformat.h to
3308 libavcodec/avcodec.h.
3310 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3311 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3312 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3313 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3314 PIX_FMT_BGR32_1 are now macros.
3315 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3316 Re-sort the enum PixelFormat list accordingly.
3317 This change breaks API/ABI backward compatibility.
3319 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3320 Add the enum PixelFormat values:
3321 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3322 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3324 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3325 The Mersenne Twister PRNG implemented through the av_random* functions
3326 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3329 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3330 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3331 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3332 and av_fifo_realloc2.
3333 In addition, the order of the function arguments of av_fifo_generic_read
3334 was changed to match av_fifo_generic_write.
3335 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3336 applications, they may not use sizeof() or directly access members.
3338 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3339 Introduce a new metadata API (see av_metadata_get() and friends).
3340 The old API is now deprecated and should not be used anymore. This especially
3341 includes the following structure fields:
3342 - AVFormatContext.title
3343 - AVFormatContext.author
3344 - AVFormatContext.copyright
3345 - AVFormatContext.comment
3346 - AVFormatContext.album
3347 - AVFormatContext.year
3348 - AVFormatContext.track
3349 - AVFormatContext.genre
3352 - AVProgram.provider_name
