360 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
361 (via an entry named "rotate"). Use av_stream_get_side_data() with
362 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
363 av_display_rotation_get(). The same is done for muxing. Instead of adding a
364 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
365 to be added to the AVStream.

524 Fix accidental ABI breakage in AVFilterContext.
525 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
527 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be

595 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

600 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
601 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
602 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
603 The default value for this option will change to "ass" at the next major
604 libavcodec version bump.
606 The current default is "ass_with_timings" for compatibility. This means that
607 all subtitles text decoders currently still output ASS with timings printed
608 as strings in the AVSubtitles.rects[N]->ass fields.
610 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
611 timing is limited to a 1/100 time base, so this is relevant for any subtitles
612 format needing a bigger one), ease timing adjustments, and prevents the need
613 of removing the timing from the decoded string yourself. This form is also
614 known as "the Matroska form". The timing information (start time, duration)
615 can be found in the AVSubtitles fields.

3020 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3021 Change the signature of avfilter_register() to make it return an
3022 int. This is required since now the registration operation may fail.
3024 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3025 Make the pixdesc.h API public.
3027 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3028 Add a next field to AVFilter, this is used for simplifying the
3029 registration and management of the registered filters.
3031 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3032 Add a description field to AVFilter.
3034 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3035 Change the interface of avfilter_make_format_list() from
3036 avfilter_make_format_list(int n, ...) to
3037 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3039 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3040 Make avfilter_get_video_buffer() recursive and add the w and h
3043 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3044 Add w and h fields to AVFilterPic.
3046 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3047 This is now an unsigned int instead of a signed int.
3049 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3050 Add a pts field to AVSubtitle which gives the subtitle packet pts
3051 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3052 not work right without this.
3054 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3055 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3056 major version. Use AV_PKT_FLAG_KEY instead.
3058 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3059 av_lockmgr_register() can be used to register a callback function
3060 that lavc (and in the future, libraries that depend on lavc) can use
3061 to implement mutexes. The application should provide a callback function
3062 that implements the AV_LOCK_* operations described in avcodec.h.
3063 When the lock manager is registered, FFmpeg is guaranteed to behave
3064 correctly in a multi-threaded application.
3066 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3067 av_free_packet() is no longer an inline function. It is now exported.
3069 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3070 Please use NULL instead. This has been supported since r16506
3071 (lavf > 52.23.1, lavc > 52.10.0).
3073 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3074 The old decoding functions are deprecated, all new code should use the
3075 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3076 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3077 argument instead of a const uint8_t *buf / int buf_size pair.
3079 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3080 Introduce the av_fifo_space() function.
3082 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3083 Move AVPacket declaration from libavformat/avformat.h to
3084 libavcodec/avcodec.h.
3086 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3087 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3088 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3089 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3090 PIX_FMT_BGR32_1 are now macros.
3091 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3092 Re-sort the enum PixelFormat list accordingly.
3093 This change breaks API/ABI backward compatibility.
3095 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3096 Add the enum PixelFormat values:
3097 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3098 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3100 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3101 The Mersenne Twister PRNG implemented through the av_random* functions
3102 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3105 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3106 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3107 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3108 and av_fifo_realloc2.
3109 In addition, the order of the function arguments of av_fifo_generic_read
3110 was changed to match av_fifo_generic_write.
3111 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3112 applications, they may not use sizeof() or directly access members.
3114 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3115 Introduce a new metadata API (see av_metadata_get() and friends).
3116 The old API is now deprecated and should not be used anymore. This especially
3117 includes the following structure fields:
3118 - AVFormatContext.title
3119 - AVFormatContext.author
3120 - AVFormatContext.copyright
3121 - AVFormatContext.comment
3122 - AVFormatContext.album
3123 - AVFormatContext.year
3124 - AVFormatContext.track
3125 - AVFormatContext.genre
3128 - AVProgram.provider_name
