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

410 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
411 Deprecate the entire library. Merged years ago to provide compatibility
412 with Libav, it remained unmaintained by the FFmpeg project and duplicated
413 functionality provided by libswresample.
415 In order to improve consistency and reduce attack surface, it has been deprecated.
416 Users of this library are asked to migrate to libswresample, which, as well as
417 providing more functionality, is faster and has higher accuracy.

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

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

828 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
829 the reset of the ASS ReadOrder field on flush. This affects the content of
830 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
833 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
834 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
835 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
836 The default value for this option will change to "ass" at the next major
837 libavcodec version bump.
839 The current default is "ass_with_timings" for compatibility. This means that
840 all subtitles text decoders currently still output ASS with timings printed
841 as strings in the AVSubtitles.rects[N]->ass fields.
843 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
844 timing is limited to a 1/100 time base, so this is relevant for any subtitles
845 format needing a bigger one), ease timing adjustments, and prevents the need
846 of removing the timing from the decoded string yourself. This form is also
847 known as "the Matroska form". The timing information (start time, duration)
848 can be found in the AVSubtitles fields.

3250 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3251 Introduce the avfilter_next() function.
3253 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3254 Change the signature of avfilter_register() to make it return an
3255 int. This is required since now the registration operation may fail.
3257 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3258 Make the pixdesc.h API public.

3282 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3283 Add a pts field to AVSubtitle which gives the subtitle packet pts
3284 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3285 not work right without this.
3287 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3288 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3289 major version. Use AV_PKT_FLAG_KEY instead.
3291 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3292 av_lockmgr_register() can be used to register a callback function
3293 that lavc (and in the future, libraries that depend on lavc) can use
3294 to implement mutexes. The application should provide a callback function
3295 that implements the AV_LOCK_* operations described in avcodec.h.
3296 When the lock manager is registered, FFmpeg is guaranteed to behave
3297 correctly in a multi-threaded application.
3299 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3300 av_free_packet() is no longer an inline function. It is now exported.
3302 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3303 Please use NULL instead. This has been supported since r16506
3304 (lavf > 52.23.1, lavc > 52.10.0).
3306 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3307 The old decoding functions are deprecated, all new code should use the
3308 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3309 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3310 argument instead of a const uint8_t *buf / int buf_size pair.
3312 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3313 Introduce the av_fifo_space() function.
3315 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3316 Move AVPacket declaration from libavformat/avformat.h to
3317 libavcodec/avcodec.h.
3319 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3320 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3321 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3322 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3323 PIX_FMT_BGR32_1 are now macros.
3324 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3325 Re-sort the enum PixelFormat list accordingly.
3326 This change breaks API/ABI backward compatibility.
3328 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3329 Add the enum PixelFormat values:
3330 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3331 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3333 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3334 The Mersenne Twister PRNG implemented through the av_random* functions
3335 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3338 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3339 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3340 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3341 and av_fifo_realloc2.
3342 In addition, the order of the function arguments of av_fifo_generic_read
3343 was changed to match av_fifo_generic_write.
3344 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3345 applications, they may not use sizeof() or directly access members.
3347 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3348 Introduce a new metadata API (see av_metadata_get() and friends).
3349 The old API is now deprecated and should not be used anymore. This especially
3350 includes the following structure fields:
3351 - AVFormatContext.title
3352 - AVFormatContext.author
3353 - AVFormatContext.copyright
3354 - AVFormatContext.comment
3355 - AVFormatContext.album
3356 - AVFormatContext.year
3357 - AVFormatContext.track
3358 - AVFormatContext.genre
3361 - AVProgram.provider_name
