416 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
417 (via an entry named "rotate"). Use av_stream_get_side_data() with
418 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
419 av_display_rotation_get(). The same is done for muxing. Instead of adding a
420 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
421 to be added to the AVStream.

526 Decoders now export the frame timestamp as AVFrame.pts. It was
527 previously exported as AVFrame.pkt_pts, which is now deprecated.
529 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
530 and not the codec timebase.

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

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

656 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
657 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
658 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
659 The default value for this option will change to "ass" at the next major
660 libavcodec version bump.
662 The current default is "ass_with_timings" for compatibility. This means that
663 all subtitles text decoders currently still output ASS with timings printed
664 as strings in the AVSubtitles.rects[N]->ass fields.
666 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
667 timing is limited to a 1/100 time base, so this is relevant for any subtitles
668 format needing a bigger one), ease timing adjustments, and prevents the need
669 of removing the timing from the decoded string yourself. This form is also
670 known as "the Matroska form". The timing information (start time, duration)
671 can be found in the AVSubtitles fields.

1868 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1869 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1899 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1900 should now be used instead of accessing AVFilterPad members
1903 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1904 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1905 and av_channel_layout_extract_channel().

1924 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1925 For audio formats with fixed frame size, the last frame
1926 no longer needs to be padded with silence, libavcodec
1927 will handle this internally (effectively all encoders
1928 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3042 Change the avfilter_add_colorspace() signature, make it accept an
3043 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
3045 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
3046 Add avfilter_add_colorspace().
3048 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
3049 Add av_match_ext(), it should be used in place of match_ext().

3071 Remove the next field from AVFilter, this is not anymore required.
3073 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3074 Introduce the avfilter_next() function.
3076 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3077 Change the signature of avfilter_register() to make it return an
3078 int. This is required since now the registration operation may fail.
3080 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3081 Make the pixdesc.h API public.
3083 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3088 Add a description field to AVFilter.
3090 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3091 Change the interface of avfilter_make_format_list() from

3095 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3096 Make avfilter_get_video_buffer() recursive and add the w and h
3099 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3100 Add w and h fields to AVFilterPic.
3102 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3103 This is now an unsigned int instead of a signed int.
3105 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3106 Add a pts field to AVSubtitle which gives the subtitle packet pts
3107 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3108 not work right without this.
3110 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3111 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3112 major version. Use AV_PKT_FLAG_KEY instead.
3114 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3115 av_lockmgr_register() can be used to register a callback function
3116 that lavc (and in the future, libraries that depend on lavc) can use
3117 to implement mutexes. The application should provide a callback function
3118 that implements the AV_LOCK_* operations described in avcodec.h.
3119 When the lock manager is registered, FFmpeg is guaranteed to behave
3120 correctly in a multi-threaded application.
3122 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3123 av_free_packet() is no longer an inline function. It is now exported.
3125 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3126 Please use NULL instead. This has been supported since r16506
3127 (lavf > 52.23.1, lavc > 52.10.0).
3129 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3130 The old decoding functions are deprecated, all new code should use the
3131 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3132 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3133 argument instead of a const uint8_t *buf / int buf_size pair.
3135 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3136 Introduce the av_fifo_space() function.
3138 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3139 Move AVPacket declaration from libavformat/avformat.h to
3140 libavcodec/avcodec.h.
3142 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3143 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3144 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3145 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3146 PIX_FMT_BGR32_1 are now macros.
3147 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3148 Re-sort the enum PixelFormat list accordingly.
3149 This change breaks API/ABI backward compatibility.
3151 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3152 Add the enum PixelFormat values:
3153 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3154 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3156 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3157 The Mersenne Twister PRNG implemented through the av_random* functions
3158 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3161 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3162 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3163 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3164 and av_fifo_realloc2.
3165 In addition, the order of the function arguments of av_fifo_generic_read
3166 was changed to match av_fifo_generic_write.
3167 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3168 applications, they may not use sizeof() or directly access members.
3170 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3171 Introduce a new metadata API (see av_metadata_get() and friends).
3172 The old API is now deprecated and should not be used anymore. This especially
3173 includes the following structure fields:
3174 - AVFormatContext.title
3175 - AVFormatContext.author
3176 - AVFormatContext.copyright
3177 - AVFormatContext.comment
3178 - AVFormatContext.album
3179 - AVFormatContext.year
3180 - AVFormatContext.track
3181 - AVFormatContext.genre
3184 - AVProgram.provider_name
