299 renamed to "stimeout" (the "timeout" option will essentially change semantics).
301 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
302 Deprecate AVFormatContext filename field which had limited length, use the

327 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
328 Deprecate the entire library. Merged years ago to provide compatibility
329 with Libav, it remained unmaintained by the FFmpeg project and duplicated
330 functionality provided by libswresample.
332 In order to improve consistency and reduce attack surface, it has been deprecated.
333 Users of this library are asked to migrate to libswresample, which, as well as
334 providing more functionality, is faster and has higher accuracy.
336 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

393 2017-09-26 - b1cf151c4d - lavc 57.106.102 - avcodec.h
394 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
395 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
396 (avcodec_send_packet/avcodec_receive_frame) always work with reference

482 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
483 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
484 set the Cuda device handle.

510 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
511 (via an entry named "rotate"). Use av_stream_get_side_data() with
512 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
513 av_display_rotation_get(). The same is done for muxing. Instead of adding a
514 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
515 to be added to the AVStream.

550 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
551 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the

555 Remove requirement to use AVOption or accessors to access certain fields
556 in AVFrame, AVCodecContext, and AVFormatContext that were previously
557 documented as "no direct access" allowed.

575 Deprecate struct vaapi_context and the vaapi.h installed header.

620 Decoders now export the frame timestamp as AVFrame.pts. It was
621 previously exported as AVFrame.pkt_pts, which is now deprecated.
623 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
624 and not the codec timebase.

674 Fix accidental ABI breakage in AVFilterContext.
675 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
677 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
678 compatible with lavfi>=6.47.100. Potentially also affects other users of

745 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

750 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
751 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
752 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
753 The default value for this option will change to "ass" at the next major
754 libavcodec version bump.
756 The current default is "ass_with_timings" for compatibility. This means that
757 all subtitles text decoders currently still output ASS with timings printed
758 as strings in the AVSubtitles.rects[N]->ass fields.
760 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
761 timing is limited to a 1/100 time base, so this is relevant for any subtitles
762 format needing a bigger one), ease timing adjustments, and prevents the need
763 of removing the timing from the decoded string yourself. This form is also

3170 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3171 Change the signature of avfilter_register() to make it return an
3172 int. This is required since now the registration operation may fail.
3174 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3175 Make the pixdesc.h API public.

3199 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3200 Add a pts field to AVSubtitle which gives the subtitle packet pts
3201 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3204 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3205 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3206 major version. Use AV_PKT_FLAG_KEY instead.
3208 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3209 av_lockmgr_register() can be used to register a callback function
3210 that lavc (and in the future, libraries that depend on lavc) can use
3211 to implement mutexes. The application should provide a callback function
3212 that implements the AV_LOCK_* operations described in avcodec.h.
3213 When the lock manager is registered, FFmpeg is guaranteed to behave
3214 correctly in a multi-threaded application.
3216 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3217 av_free_packet() is no longer an inline function. It is now exported.
3219 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3220 Please use NULL instead. This has been supported since r16506
3221 (lavf > 52.23.1, lavc > 52.10.0).
3223 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3224 The old decoding functions are deprecated, all new code should use the
3225 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3226 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3227 argument instead of a const uint8_t *buf / int buf_size pair.
3229 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3230 Introduce the av_fifo_space() function.
3232 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3233 Move AVPacket declaration from libavformat/avformat.h to
3234 libavcodec/avcodec.h.
3236 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3237 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3238 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3239 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3240 PIX_FMT_BGR32_1 are now macros.
3241 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3242 Re-sort the enum PixelFormat list accordingly.
3243 This change breaks API/ABI backward compatibility.
3245 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3246 Add the enum PixelFormat values:
3247 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3248 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3250 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3251 The Mersenne Twister PRNG implemented through the av_random* functions
3252 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3255 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3256 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3257 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3258 and av_fifo_realloc2.
3259 In addition, the order of the function arguments of av_fifo_generic_read
3260 was changed to match av_fifo_generic_write.
3261 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3262 applications, they may not use sizeof() or directly access members.
3264 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3265 Introduce a new metadata API (see av_metadata_get() and friends).
3266 The old API is now deprecated and should not be used anymore. This especially
3267 includes the following structure fields:
3268 - AVFormatContext.title
3269 - AVFormatContext.author
3270 - AVFormatContext.copyright
3271 - AVFormatContext.comment
3272 - AVFormatContext.album
3273 - AVFormatContext.year
3274 - AVFormatContext.track
3275 - AVFormatContext.genre
3278 - AVProgram.provider_name
