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

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

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

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

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

1877 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1878 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1908 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1909 should now be used instead of accessing AVFilterPad members
1912 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1913 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1914 and av_channel_layout_extract_channel().

1933 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1934 For audio formats with fixed frame size, the last frame
1935 no longer needs to be padded with silence, libavcodec
1936 will handle this internally (effectively all encoders
1937 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3051 Change the avfilter_add_colorspace() signature, make it accept an
3052 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
3054 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
3055 Add avfilter_add_colorspace().
3057 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()

3082 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3083 Introduce the avfilter_next() function.
3085 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3086 Change the signature of avfilter_register() to make it return an
3087 int. This is required since now the registration operation may fail.
3089 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3090 Make the pixdesc.h API public.
3092 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3097 Add a description field to AVFilter.
3099 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3100 Change the interface of avfilter_make_format_list() from

3111 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

3114 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3115 Add a pts field to AVSubtitle which gives the subtitle packet pts
3116 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3117 not work right without this.
3119 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3120 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3121 major version. Use AV_PKT_FLAG_KEY instead.
3123 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3124 av_lockmgr_register() can be used to register a callback function
3125 that lavc (and in the future, libraries that depend on lavc) can use
3126 to implement mutexes. The application should provide a callback function
3127 that implements the AV_LOCK_* operations described in avcodec.h.
3128 When the lock manager is registered, FFmpeg is guaranteed to behave
3129 correctly in a multi-threaded application.
3131 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3132 av_free_packet() is no longer an inline function. It is now exported.
3134 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3135 Please use NULL instead. This has been supported since r16506
3136 (lavf > 52.23.1, lavc > 52.10.0).
3138 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3139 The old decoding functions are deprecated, all new code should use the
3140 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3141 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3142 argument instead of a const uint8_t *buf / int buf_size pair.
3144 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3145 Introduce the av_fifo_space() function.
3147 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3148 Move AVPacket declaration from libavformat/avformat.h to
3149 libavcodec/avcodec.h.
3151 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3152 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3153 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3154 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3155 PIX_FMT_BGR32_1 are now macros.
3156 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3157 Re-sort the enum PixelFormat list accordingly.
3158 This change breaks API/ABI backward compatibility.
3160 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3161 Add the enum PixelFormat values:
3162 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3163 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3165 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3166 The Mersenne Twister PRNG implemented through the av_random* functions
3167 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3170 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3171 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3172 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3173 and av_fifo_realloc2.
3174 In addition, the order of the function arguments of av_fifo_generic_read
3175 was changed to match av_fifo_generic_write.
3176 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3177 applications, they may not use sizeof() or directly access members.
3179 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3180 Introduce a new metadata API (see av_metadata_get() and friends).
3181 The old API is now deprecated and should not be used anymore. This especially
3182 includes the following structure fields:
3183 - AVFormatContext.title
3184 - AVFormatContext.author
3185 - AVFormatContext.copyright
3186 - AVFormatContext.comment
3187 - AVFormatContext.album
3188 - AVFormatContext.year
3189 - AVFormatContext.track
3190 - AVFormatContext.genre
3193 - AVProgram.provider_name
