424 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
425 (via an entry named "rotate"). Use av_stream_get_side_data() with
426 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
427 av_display_rotation_get(). The same is done for muxing. Instead of adding a
428 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
429 to be added to the AVStream.

534 Decoders now export the frame timestamp as AVFrame.pts. It was
535 previously exported as AVFrame.pkt_pts, which is now deprecated.
537 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
538 and not the codec timebase.

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

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

664 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
665 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
666 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
667 The default value for this option will change to "ass" at the next major
668 libavcodec version bump.
670 The current default is "ass_with_timings" for compatibility. This means that
671 all subtitles text decoders currently still output ASS with timings printed
672 as strings in the AVSubtitles.rects[N]->ass fields.
674 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
675 timing is limited to a 1/100 time base, so this is relevant for any subtitles
676 format needing a bigger one), ease timing adjustments, and prevents the need
677 of removing the timing from the decoded string yourself. This form is also
678 known as "the Matroska form". The timing information (start time, duration)
679 can be found in the AVSubtitles fields.

1876 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1877 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1907 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1908 should now be used instead of accessing AVFilterPad members

1932 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1933 For audio formats with fixed frame size, the last frame
1934 no longer needs to be padded with silence, libavcodec
1935 will handle this internally (effectively all encoders
1936 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3081 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3082 Introduce the avfilter_next() function.
3084 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3085 Change the signature of avfilter_register() to make it return an
3086 int. This is required since now the registration operation may fail.
3088 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3089 Make the pixdesc.h API public.
3091 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3096 Add a description field to AVFilter.
3098 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3099 Change the interface of avfilter_make_format_list() from

3108 Add w and h fields to AVFilterPic.
3110 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

3113 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3114 Add a pts field to AVSubtitle which gives the subtitle packet pts
3115 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3116 not work right without this.
3118 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3119 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3120 major version. Use AV_PKT_FLAG_KEY instead.
3122 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3123 av_lockmgr_register() can be used to register a callback function
3124 that lavc (and in the future, libraries that depend on lavc) can use
3125 to implement mutexes. The application should provide a callback function
3126 that implements the AV_LOCK_* operations described in avcodec.h.
3127 When the lock manager is registered, FFmpeg is guaranteed to behave
3128 correctly in a multi-threaded application.
3130 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3131 av_free_packet() is no longer an inline function. It is now exported.
3133 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3134 Please use NULL instead. This has been supported since r16506
3135 (lavf > 52.23.1, lavc > 52.10.0).
3137 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3138 The old decoding functions are deprecated, all new code should use the
3139 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3140 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3141 argument instead of a const uint8_t *buf / int buf_size pair.
3143 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3144 Introduce the av_fifo_space() function.
3146 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3147 Move AVPacket declaration from libavformat/avformat.h to
3148 libavcodec/avcodec.h.
3150 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3151 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3152 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3153 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3154 PIX_FMT_BGR32_1 are now macros.
3155 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3156 Re-sort the enum PixelFormat list accordingly.
3157 This change breaks API/ABI backward compatibility.
3159 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3160 Add the enum PixelFormat values:
3161 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3162 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3164 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3165 The Mersenne Twister PRNG implemented through the av_random* functions
3166 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3169 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3170 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3171 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3172 and av_fifo_realloc2.
3173 In addition, the order of the function arguments of av_fifo_generic_read
3174 was changed to match av_fifo_generic_write.
3175 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3176 applications, they may not use sizeof() or directly access members.
3178 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3179 Introduce a new metadata API (see av_metadata_get() and friends).
3180 The old API is now deprecated and should not be used anymore. This especially
3181 includes the following structure fields:
3182 - AVFormatContext.title
3183 - AVFormatContext.author
3184 - AVFormatContext.copyright
3185 - AVFormatContext.comment
3186 - AVFormatContext.album
3187 - AVFormatContext.year
3188 - AVFormatContext.track
3189 - AVFormatContext.genre
3192 - AVProgram.provider_name
