385 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated

473 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
474 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
475 set the Cuda device handle.
477 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

501 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
502 (via an entry named "rotate"). Use av_stream_get_side_data() with
503 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
504 av_display_rotation_get(). The same is done for muxing. Instead of adding a
505 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
506 to be added to the AVStream.

521 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
522 bump, and libavformat will behave as if it were always set.
523 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().

541 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
542 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
543 native decoder format. (The default value is not changed.)
545 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
546 Remove requirement to use AVOption or accessors to access certain fields
547 in AVFrame, AVCodecContext, and AVFormatContext that were previously
548 documented as "no direct access" allowed.

566 Deprecate struct vaapi_context and the vaapi.h installed header.
567 Callers should set AVCodecContext.hw_frames_ctx instead.

611 Decoders now export the frame timestamp as AVFrame.pts. It was
612 previously exported as AVFrame.pkt_pts, which is now deprecated.
614 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
615 and not the codec timebase.

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

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

741 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
742 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
743 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
744 The default value for this option will change to "ass" at the next major
745 libavcodec version bump.
747 The current default is "ass_with_timings" for compatibility. This means that
748 all subtitles text decoders currently still output ASS with timings printed
749 as strings in the AVSubtitles.rects[N]->ass fields.
751 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
752 timing is limited to a 1/100 time base, so this is relevant for any subtitles
753 format needing a bigger one), ease timing adjustments, and prevents the need
754 of removing the timing from the decoded string yourself. This form is also
755 known as "the Matroska form". The timing information (start time, duration)
756 can be found in the AVSubtitles fields.

3159 Introduce the avfilter_next() function.
3161 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3162 Change the signature of avfilter_register() to make it return an
3163 int. This is required since now the registration operation may fail.
3165 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3166 Make the pixdesc.h API public.

3190 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3191 Add a pts field to AVSubtitle which gives the subtitle packet pts
3192 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3195 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3196 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3197 major version. Use AV_PKT_FLAG_KEY instead.
3199 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3200 av_lockmgr_register() can be used to register a callback function
3201 that lavc (and in the future, libraries that depend on lavc) can use
3202 to implement mutexes. The application should provide a callback function
3203 that implements the AV_LOCK_* operations described in avcodec.h.
3204 When the lock manager is registered, FFmpeg is guaranteed to behave
3205 correctly in a multi-threaded application.
3207 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3208 av_free_packet() is no longer an inline function. It is now exported.
3210 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3211 Please use NULL instead. This has been supported since r16506
3212 (lavf > 52.23.1, lavc > 52.10.0).
3214 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3215 The old decoding functions are deprecated, all new code should use the
3216 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3217 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3218 argument instead of a const uint8_t *buf / int buf_size pair.
3220 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3221 Introduce the av_fifo_space() function.
3223 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3224 Move AVPacket declaration from libavformat/avformat.h to
3225 libavcodec/avcodec.h.
3227 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3228 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3229 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3230 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3231 PIX_FMT_BGR32_1 are now macros.
3232 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3233 Re-sort the enum PixelFormat list accordingly.
3234 This change breaks API/ABI backward compatibility.
3236 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3237 Add the enum PixelFormat values:
3238 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3239 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3241 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3242 The Mersenne Twister PRNG implemented through the av_random* functions
3243 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3246 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3247 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3248 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3249 and av_fifo_realloc2.
3250 In addition, the order of the function arguments of av_fifo_generic_read
3251 was changed to match av_fifo_generic_write.
3252 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3253 applications, they may not use sizeof() or directly access members.
3255 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3256 Introduce a new metadata API (see av_metadata_get() and friends).
3257 The old API is now deprecated and should not be used anymore. This especially
3258 includes the following structure fields:
3259 - AVFormatContext.title
3260 - AVFormatContext.author
3261 - AVFormatContext.copyright
3262 - AVFormatContext.comment
3263 - AVFormatContext.album
3264 - AVFormatContext.year
3265 - AVFormatContext.track
3266 - AVFormatContext.genre
3269 - AVProgram.provider_name
