355 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
356 (via an entry named "rotate"). Use av_stream_get_side_data() with
357 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

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

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

595 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
596 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
597 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
598 The default value for this option will change to "ass" at the next major
599 libavcodec version bump.
601 The current default is "ass_with_timings" for compatibility. This means that
602 all subtitles text decoders currently still output ASS with timings printed
603 as strings in the AVSubtitles.rects[N]->ass fields.
605 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
606 timing is limited to a 1/100 time base, so this is relevant for any subtitles
607 format needing a bigger one), ease timing adjustments, and prevents the need
608 of removing the timing from the decoded string yourself. This form is also
609 known as "the Matroska form". The timing information (start time, duration)
610 can be found in the AVSubtitles fields.

3015 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3016 Change the signature of avfilter_register() to make it return an
3017 int. This is required since now the registration operation may fail.
3019 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3020 Make the pixdesc.h API public.
3022 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3023 Add a next field to AVFilter, this is used for simplifying the
3024 registration and management of the registered filters.
3026 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3027 Add a description field to AVFilter.
3029 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3030 Change the interface of avfilter_make_format_list() from
3031 avfilter_make_format_list(int n, ...) to
3032 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3034 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3035 Make avfilter_get_video_buffer() recursive and add the w and h
3038 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3039 Add w and h fields to AVFilterPic.
3041 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3042 This is now an unsigned int instead of a signed int.
3044 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3045 Add a pts field to AVSubtitle which gives the subtitle packet pts
3046 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3047 not work right without this.
3049 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3050 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3051 major version. Use AV_PKT_FLAG_KEY instead.
3053 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3054 av_lockmgr_register() can be used to register a callback function
3055 that lavc (and in the future, libraries that depend on lavc) can use
3056 to implement mutexes. The application should provide a callback function
3057 that implements the AV_LOCK_* operations described in avcodec.h.
3058 When the lock manager is registered, FFmpeg is guaranteed to behave
3059 correctly in a multi-threaded application.
3061 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3062 av_free_packet() is no longer an inline function. It is now exported.
3064 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3065 Please use NULL instead. This has been supported since r16506
3066 (lavf > 52.23.1, lavc > 52.10.0).
3068 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3069 The old decoding functions are deprecated, all new code should use the
3070 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3071 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3072 argument instead of a const uint8_t *buf / int buf_size pair.
3074 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3075 Introduce the av_fifo_space() function.
3077 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3078 Move AVPacket declaration from libavformat/avformat.h to
3079 libavcodec/avcodec.h.
3081 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3082 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3083 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3084 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3085 PIX_FMT_BGR32_1 are now macros.
3086 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3087 Re-sort the enum PixelFormat list accordingly.
3088 This change breaks API/ABI backward compatibility.
3090 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3091 Add the enum PixelFormat values:
3092 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3093 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3095 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3096 The Mersenne Twister PRNG implemented through the av_random* functions
3097 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3100 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3101 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3102 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3103 and av_fifo_realloc2.
3104 In addition, the order of the function arguments of av_fifo_generic_read
3105 was changed to match av_fifo_generic_write.
3106 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3107 applications, they may not use sizeof() or directly access members.
3109 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3110 Introduce a new metadata API (see av_metadata_get() and friends).
3111 The old API is now deprecated and should not be used anymore. This especially
3112 includes the following structure fields:
3113 - AVFormatContext.title
3114 - AVFormatContext.author
3115 - AVFormatContext.copyright
3116 - AVFormatContext.comment
3117 - AVFormatContext.album
3118 - AVFormatContext.year
3119 - AVFormatContext.track
3120 - AVFormatContext.genre
3123 - AVProgram.provider_name
