407 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
408 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
409 set the Cuda device handle.

435 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
436 (via an entry named "rotate"). Use av_stream_get_side_data() with
437 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
438 av_display_rotation_get(). The same is done for muxing. Instead of adding a
439 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
440 to be added to the AVStream.

545 Decoders now export the frame timestamp as AVFrame.pts. It was
546 previously exported as AVFrame.pkt_pts, which is now deprecated.
548 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
549 and not the codec timebase.

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

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

675 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
676 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
677 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
678 The default value for this option will change to "ass" at the next major
679 libavcodec version bump.
681 The current default is "ass_with_timings" for compatibility. This means that
682 all subtitles text decoders currently still output ASS with timings printed
683 as strings in the AVSubtitles.rects[N]->ass fields.
685 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
686 timing is limited to a 1/100 time base, so this is relevant for any subtitles
687 format needing a bigger one), ease timing adjustments, and prevents the need
688 of removing the timing from the decoded string yourself. This form is also
689 known as "the Matroska form". The timing information (start time, duration)
690 can be found in the AVSubtitles fields.

1944 For audio formats with fixed frame size, the last frame
1945 no longer needs to be padded with silence, libavcodec
1946 will handle this internally (effectively all encoders
1947 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3092 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3093 Introduce the avfilter_next() function.
3095 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3096 Change the signature of avfilter_register() to make it return an
3097 int. This is required since now the registration operation may fail.
3099 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3100 Make the pixdesc.h API public.
3102 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3124 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3125 Add a pts field to AVSubtitle which gives the subtitle packet pts
3126 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3127 not work right without this.
3129 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3130 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3131 major version. Use AV_PKT_FLAG_KEY instead.
3133 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3134 av_lockmgr_register() can be used to register a callback function
3135 that lavc (and in the future, libraries that depend on lavc) can use
3136 to implement mutexes. The application should provide a callback function
3137 that implements the AV_LOCK_* operations described in avcodec.h.
3138 When the lock manager is registered, FFmpeg is guaranteed to behave
3139 correctly in a multi-threaded application.
3141 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3142 av_free_packet() is no longer an inline function. It is now exported.
3144 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3145 Please use NULL instead. This has been supported since r16506
3146 (lavf > 52.23.1, lavc > 52.10.0).
3148 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3149 The old decoding functions are deprecated, all new code should use the
3150 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3151 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3152 argument instead of a const uint8_t *buf / int buf_size pair.
3154 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3155 Introduce the av_fifo_space() function.
3157 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3158 Move AVPacket declaration from libavformat/avformat.h to
3159 libavcodec/avcodec.h.
3161 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3162 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3163 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3164 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3165 PIX_FMT_BGR32_1 are now macros.
3166 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3167 Re-sort the enum PixelFormat list accordingly.
3168 This change breaks API/ABI backward compatibility.
3170 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3171 Add the enum PixelFormat values:
3172 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3173 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3175 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3176 The Mersenne Twister PRNG implemented through the av_random* functions
3177 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3180 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3181 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3182 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3183 and av_fifo_realloc2.
3184 In addition, the order of the function arguments of av_fifo_generic_read
3185 was changed to match av_fifo_generic_write.
3186 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3187 applications, they may not use sizeof() or directly access members.
3189 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3190 Introduce a new metadata API (see av_metadata_get() and friends).
3191 The old API is now deprecated and should not be used anymore. This especially
3192 includes the following structure fields:
3193 - AVFormatContext.title
3194 - AVFormatContext.author
3195 - AVFormatContext.copyright
3196 - AVFormatContext.comment
3197 - AVFormatContext.album
3198 - AVFormatContext.year
3199 - AVFormatContext.track
3200 - AVFormatContext.genre
3203 - AVProgram.provider_name
