253 is over, the old "timeout" option will be removed, and "stimeout" will be
254 renamed to "stimeout" (the "timeout" option will essentially change semantics).
256 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h

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

465 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
466 (via an entry named "rotate"). Use av_stream_get_side_data() with
467 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
468 av_display_rotation_get(). The same is done for muxing. Instead of adding a
469 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
470 to be added to the AVStream.

575 Decoders now export the frame timestamp as AVFrame.pts. It was
576 previously exported as AVFrame.pkt_pts, which is now deprecated.
578 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
579 and not the codec timebase.

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

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

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

1974 For audio formats with fixed frame size, the last frame
1975 no longer needs to be padded with silence, libavcodec
1976 will handle this internally (effectively all encoders
1977 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3154 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3155 Add a pts field to AVSubtitle which gives the subtitle packet pts
3156 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3159 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3160 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3161 major version. Use AV_PKT_FLAG_KEY instead.
3163 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3164 av_lockmgr_register() can be used to register a callback function
3165 that lavc (and in the future, libraries that depend on lavc) can use
3166 to implement mutexes. The application should provide a callback function
3167 that implements the AV_LOCK_* operations described in avcodec.h.
3168 When the lock manager is registered, FFmpeg is guaranteed to behave
3169 correctly in a multi-threaded application.
3171 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3172 av_free_packet() is no longer an inline function. It is now exported.
3174 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3175 Please use NULL instead. This has been supported since r16506
3176 (lavf > 52.23.1, lavc > 52.10.0).
3178 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3179 The old decoding functions are deprecated, all new code should use the
3180 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3181 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3182 argument instead of a const uint8_t *buf / int buf_size pair.
3184 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3185 Introduce the av_fifo_space() function.
3187 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3188 Move AVPacket declaration from libavformat/avformat.h to
3189 libavcodec/avcodec.h.
3191 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3192 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3193 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3194 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3195 PIX_FMT_BGR32_1 are now macros.
3196 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3197 Re-sort the enum PixelFormat list accordingly.
3198 This change breaks API/ABI backward compatibility.
3200 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3201 Add the enum PixelFormat values:
3202 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3203 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3205 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3206 The Mersenne Twister PRNG implemented through the av_random* functions
3207 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3210 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3211 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3212 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3213 and av_fifo_realloc2.
3214 In addition, the order of the function arguments of av_fifo_generic_read
3215 was changed to match av_fifo_generic_write.
3216 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3217 applications, they may not use sizeof() or directly access members.
3219 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3220 Introduce a new metadata API (see av_metadata_get() and friends).
3221 The old API is now deprecated and should not be used anymore. This especially
3222 includes the following structure fields:
3223 - AVFormatContext.title
3224 - AVFormatContext.author
3225 - AVFormatContext.copyright
3226 - AVFormatContext.comment
3227 - AVFormatContext.album
3228 - AVFormatContext.year
3229 - AVFormatContext.track
3230 - AVFormatContext.genre
3233 - AVProgram.provider_name
