444 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
445 set the Cuda device handle.

471 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
472 (via an entry named "rotate"). Use av_stream_get_side_data() with
473 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
474 av_display_rotation_get(). The same is done for muxing. Instead of adding a
475 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
476 to be added to the AVStream.

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

581 Decoders now export the frame timestamp as AVFrame.pts. It was
582 previously exported as AVFrame.pkt_pts, which is now deprecated.
584 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
585 and not the codec timebase.

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

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

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

3128 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3129 Introduce the avfilter_next() function.
3131 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3132 Change the signature of avfilter_register() to make it return an
3133 int. This is required since now the registration operation may fail.
3135 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3136 Make the pixdesc.h API public.

3160 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3161 Add a pts field to AVSubtitle which gives the subtitle packet pts
3162 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3163 not work right without this.
3165 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3166 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3167 major version. Use AV_PKT_FLAG_KEY instead.
3169 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3170 av_lockmgr_register() can be used to register a callback function
3171 that lavc (and in the future, libraries that depend on lavc) can use
3172 to implement mutexes. The application should provide a callback function
3173 that implements the AV_LOCK_* operations described in avcodec.h.
3174 When the lock manager is registered, FFmpeg is guaranteed to behave
3175 correctly in a multi-threaded application.
3177 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3178 av_free_packet() is no longer an inline function. It is now exported.
3180 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3181 Please use NULL instead. This has been supported since r16506
3182 (lavf > 52.23.1, lavc > 52.10.0).
3184 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3185 The old decoding functions are deprecated, all new code should use the
3186 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3187 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3188 argument instead of a const uint8_t *buf / int buf_size pair.
3190 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3191 Introduce the av_fifo_space() function.
3193 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3194 Move AVPacket declaration from libavformat/avformat.h to
3195 libavcodec/avcodec.h.
3197 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3198 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3199 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3200 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3201 PIX_FMT_BGR32_1 are now macros.
3202 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3203 Re-sort the enum PixelFormat list accordingly.
3204 This change breaks API/ABI backward compatibility.
3206 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3207 Add the enum PixelFormat values:
3208 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3209 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3211 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3212 The Mersenne Twister PRNG implemented through the av_random* functions
3213 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3216 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3217 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3218 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3219 and av_fifo_realloc2.
3220 In addition, the order of the function arguments of av_fifo_generic_read
3221 was changed to match av_fifo_generic_write.
3222 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3223 applications, they may not use sizeof() or directly access members.
3225 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3226 Introduce a new metadata API (see av_metadata_get() and friends).
3227 The old API is now deprecated and should not be used anymore. This especially
3228 includes the following structure fields:
3229 - AVFormatContext.title
3230 - AVFormatContext.author
3231 - AVFormatContext.copyright
3232 - AVFormatContext.comment
3233 - AVFormatContext.album
3234 - AVFormatContext.year
3235 - AVFormatContext.track
3236 - AVFormatContext.genre
3239 - AVProgram.provider_name
