391 (via an entry named "rotate"). Use av_stream_get_side_data() with
392 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

394 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
395 to be added to the AVStream.

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

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

630 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
631 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
632 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
633 The default value for this option will change to "ass" at the next major
634 libavcodec version bump.
636 The current default is "ass_with_timings" for compatibility. This means that
637 all subtitles text decoders currently still output ASS with timings printed
638 as strings in the AVSubtitles.rects[N]->ass fields.
640 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
641 timing is limited to a 1/100 time base, so this is relevant for any subtitles
642 format needing a bigger one), ease timing adjustments, and prevents the need
643 of removing the timing from the decoded string yourself. This form is also
644 known as "the Matroska form". The timing information (start time, duration)
645 can be found in the AVSubtitles fields.

3044 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3045 Remove the next field from AVFilter, this is not anymore required.
3047 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3048 Introduce the avfilter_next() function.
3050 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3051 Change the signature of avfilter_register() to make it return an
3052 int. This is required since now the registration operation may fail.
3054 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3055 Make the pixdesc.h API public.
3057 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3062 Add a description field to AVFilter.
3064 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3065 Change the interface of avfilter_make_format_list() from

3079 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3080 Add a pts field to AVSubtitle which gives the subtitle packet pts
3081 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3082 not work right without this.
3084 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3085 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3086 major version. Use AV_PKT_FLAG_KEY instead.
3088 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3089 av_lockmgr_register() can be used to register a callback function
3090 that lavc (and in the future, libraries that depend on lavc) can use
3091 to implement mutexes. The application should provide a callback function
3092 that implements the AV_LOCK_* operations described in avcodec.h.
3093 When the lock manager is registered, FFmpeg is guaranteed to behave
3094 correctly in a multi-threaded application.
3096 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3097 av_free_packet() is no longer an inline function. It is now exported.
3099 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3100 Please use NULL instead. This has been supported since r16506
3101 (lavf > 52.23.1, lavc > 52.10.0).
3103 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3104 The old decoding functions are deprecated, all new code should use the
3105 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3106 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3107 argument instead of a const uint8_t *buf / int buf_size pair.
3109 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3110 Introduce the av_fifo_space() function.
3112 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3113 Move AVPacket declaration from libavformat/avformat.h to
3114 libavcodec/avcodec.h.
3116 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3117 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3118 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3119 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3120 PIX_FMT_BGR32_1 are now macros.
3121 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3122 Re-sort the enum PixelFormat list accordingly.
3123 This change breaks API/ABI backward compatibility.
3125 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3126 Add the enum PixelFormat values:
3127 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3128 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3130 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3131 The Mersenne Twister PRNG implemented through the av_random* functions
3132 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3135 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3136 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3137 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3138 and av_fifo_realloc2.
3139 In addition, the order of the function arguments of av_fifo_generic_read
3140 was changed to match av_fifo_generic_write.
3141 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3142 applications, they may not use sizeof() or directly access members.
3144 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3145 Introduce a new metadata API (see av_metadata_get() and friends).
3146 The old API is now deprecated and should not be used anymore. This especially
3147 includes the following structure fields:
3148 - AVFormatContext.title
3149 - AVFormatContext.author
3150 - AVFormatContext.copyright
3151 - AVFormatContext.comment
3152 - AVFormatContext.album
3153 - AVFormatContext.year
3154 - AVFormatContext.track
3155 - AVFormatContext.genre
3158 - AVProgram.provider_name
