243 is over, the old "timeout" option will be removed, and "stimeout" will be
244 renamed to "stimeout" (the "timeout" option will essentially change semantics).
246 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h

279 providing more functionality, is faster and has higher accuracy.

428 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
429 set the Cuda device handle.

455 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
456 (via an entry named "rotate"). Use av_stream_get_side_data() with
457 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
458 av_display_rotation_get(). The same is done for muxing. Instead of adding a
459 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
460 to be added to the AVStream.

565 Decoders now export the frame timestamp as AVFrame.pts. It was
566 previously exported as AVFrame.pkt_pts, which is now deprecated.
568 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
569 and not the codec timebase.

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

690 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
691 the reset of the ASS ReadOrder field on flush. This affects the content of

695 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
696 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
697 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
698 The default value for this option will change to "ass" at the next major
699 libavcodec version bump.
701 The current default is "ass_with_timings" for compatibility. This means that
702 all subtitles text decoders currently still output ASS with timings printed
703 as strings in the AVSubtitles.rects[N]->ass fields.
705 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
706 timing is limited to a 1/100 time base, so this is relevant for any subtitles
707 format needing a bigger one), ease timing adjustments, and prevents the need
708 of removing the timing from the decoded string yourself. This form is also
709 known as "the Matroska form". The timing information (start time, duration)
710 can be found in the AVSubtitles fields.

1964 For audio formats with fixed frame size, the last frame
1965 no longer needs to be padded with silence, libavcodec
1966 will handle this internally (effectively all encoders

3115 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3116 Change the signature of avfilter_register() to make it return an
3117 int. This is required since now the registration operation may fail.

3144 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3145 Add a pts field to AVSubtitle which gives the subtitle packet pts
3146 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3149 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3150 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3151 major version. Use AV_PKT_FLAG_KEY instead.
3153 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3154 av_lockmgr_register() can be used to register a callback function
3155 that lavc (and in the future, libraries that depend on lavc) can use
3156 to implement mutexes. The application should provide a callback function
3157 that implements the AV_LOCK_* operations described in avcodec.h.
3158 When the lock manager is registered, FFmpeg is guaranteed to behave
3159 correctly in a multi-threaded application.
3161 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3162 av_free_packet() is no longer an inline function. It is now exported.
3164 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3165 Please use NULL instead. This has been supported since r16506
3166 (lavf > 52.23.1, lavc > 52.10.0).
3168 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3169 The old decoding functions are deprecated, all new code should use the
3170 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3171 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3172 argument instead of a const uint8_t *buf / int buf_size pair.
3174 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3175 Introduce the av_fifo_space() function.
3177 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3178 Move AVPacket declaration from libavformat/avformat.h to
3179 libavcodec/avcodec.h.
3181 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3182 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3183 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3184 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3185 PIX_FMT_BGR32_1 are now macros.
3186 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3187 Re-sort the enum PixelFormat list accordingly.
3188 This change breaks API/ABI backward compatibility.
3190 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3191 Add the enum PixelFormat values:
3192 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3193 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3195 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3196 The Mersenne Twister PRNG implemented through the av_random* functions
3197 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3200 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3201 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3202 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3203 and av_fifo_realloc2.
3204 In addition, the order of the function arguments of av_fifo_generic_read
3205 was changed to match av_fifo_generic_write.
3206 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3207 applications, they may not use sizeof() or directly access members.
3209 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3210 Introduce a new metadata API (see av_metadata_get() and friends).
3211 The old API is now deprecated and should not be used anymore. This especially
3212 includes the following structure fields:
3213 - AVFormatContext.title
3214 - AVFormatContext.author
3215 - AVFormatContext.copyright
3216 - AVFormatContext.comment
3217 - AVFormatContext.album
3218 - AVFormatContext.year
3219 - AVFormatContext.track
3220 - AVFormatContext.genre
3223 - AVProgram.provider_name
