409 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
410 (via an entry named "rotate"). Use av_stream_get_side_data() with
411 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
412 av_display_rotation_get(). The same is done for muxing. Instead of adding a
413 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
414 to be added to the AVStream.

522 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

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

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

649 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
650 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
651 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
652 The default value for this option will change to "ass" at the next major
653 libavcodec version bump.
655 The current default is "ass_with_timings" for compatibility. This means that
656 all subtitles text decoders currently still output ASS with timings printed
657 as strings in the AVSubtitles.rects[N]->ass fields.
659 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
660 timing is limited to a 1/100 time base, so this is relevant for any subtitles
661 format needing a bigger one), ease timing adjustments, and prevents the need
662 of removing the timing from the decoded string yourself. This form is also
663 known as "the Matroska form". The timing information (start time, duration)
664 can be found in the AVSubtitles fields.

1861 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1862 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1892 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1893 should now be used instead of accessing AVFilterPad members

1917 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1918 For audio formats with fixed frame size, the last frame
1919 no longer needs to be padded with silence, libavcodec
1920 will handle this internally (effectively all encoders
1921 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3064 Remove the next field from AVFilter, this is not anymore required.
3066 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3067 Introduce the avfilter_next() function.
3069 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3070 Change the signature of avfilter_register() to make it return an
3071 int. This is required since now the registration operation may fail.
3073 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3074 Make the pixdesc.h API public.
3076 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3081 Add a description field to AVFilter.
3083 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3084 Change the interface of avfilter_make_format_list() from

3095 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

3098 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3099 Add a pts field to AVSubtitle which gives the subtitle packet pts
3100 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3101 not work right without this.
3103 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3104 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3105 major version. Use AV_PKT_FLAG_KEY instead.
3107 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3108 av_lockmgr_register() can be used to register a callback function
3109 that lavc (and in the future, libraries that depend on lavc) can use
3110 to implement mutexes. The application should provide a callback function
3111 that implements the AV_LOCK_* operations described in avcodec.h.
3112 When the lock manager is registered, FFmpeg is guaranteed to behave
3113 correctly in a multi-threaded application.
3115 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3116 av_free_packet() is no longer an inline function. It is now exported.
3118 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3119 Please use NULL instead. This has been supported since r16506
3120 (lavf > 52.23.1, lavc > 52.10.0).
3122 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3123 The old decoding functions are deprecated, all new code should use the
3124 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3125 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3126 argument instead of a const uint8_t *buf / int buf_size pair.
3128 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3129 Introduce the av_fifo_space() function.
3131 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3132 Move AVPacket declaration from libavformat/avformat.h to
3133 libavcodec/avcodec.h.
3135 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3136 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3137 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3138 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3139 PIX_FMT_BGR32_1 are now macros.
3140 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3141 Re-sort the enum PixelFormat list accordingly.
3142 This change breaks API/ABI backward compatibility.
3144 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3145 Add the enum PixelFormat values:
3146 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3147 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3149 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3150 The Mersenne Twister PRNG implemented through the av_random* functions
3151 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3154 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3155 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3156 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3157 and av_fifo_realloc2.
3158 In addition, the order of the function arguments of av_fifo_generic_read
3159 was changed to match av_fifo_generic_write.
3160 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3161 applications, they may not use sizeof() or directly access members.
3163 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3164 Introduce a new metadata API (see av_metadata_get() and friends).
3165 The old API is now deprecated and should not be used anymore. This especially
3166 includes the following structure fields:
3167 - AVFormatContext.title
3168 - AVFormatContext.author
3169 - AVFormatContext.copyright
3170 - AVFormatContext.comment
3171 - AVFormatContext.album
3172 - AVFormatContext.year
3173 - AVFormatContext.track
3174 - AVFormatContext.genre
3177 - AVProgram.provider_name
