327 which can create the decoder context and allocate hardware frame automatically.
328 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
329 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

400 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
401 (via an entry named "rotate"). Use av_stream_get_side_data() with
402 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
403 av_display_rotation_get(). The same is done for muxing. Instead of adding a
404 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
405 to be added to the AVStream.

511 previously exported as AVFrame.pkt_pts, which is now deprecated.
513 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

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

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

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

3026 Change the avfilter_add_colorspace() signature, make it accept an
3027 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
3029 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()

3054 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3055 Remove the next field from AVFilter, this is not anymore required.
3057 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3058 Introduce the avfilter_next() function.
3060 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3061 Change the signature of avfilter_register() to make it return an
3062 int. This is required since now the registration operation may fail.
3064 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3065 Make the pixdesc.h API public.
3067 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3072 Add a description field to AVFilter.
3074 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3075 Change the interface of avfilter_make_format_list() from

3079 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3080 Make avfilter_get_video_buffer() recursive and add the w and h
3083 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3084 Add w and h fields to AVFilterPic.
3086 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3087 This is now an unsigned int instead of a signed int.
3089 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3090 Add a pts field to AVSubtitle which gives the subtitle packet pts
3091 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3092 not work right without this.
3094 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3095 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3096 major version. Use AV_PKT_FLAG_KEY instead.
3098 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3099 av_lockmgr_register() can be used to register a callback function
3100 that lavc (and in the future, libraries that depend on lavc) can use
3101 to implement mutexes. The application should provide a callback function
3102 that implements the AV_LOCK_* operations described in avcodec.h.
3103 When the lock manager is registered, FFmpeg is guaranteed to behave
3104 correctly in a multi-threaded application.
3106 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3107 av_free_packet() is no longer an inline function. It is now exported.
3109 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3110 Please use NULL instead. This has been supported since r16506
3111 (lavf > 52.23.1, lavc > 52.10.0).
3113 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3114 The old decoding functions are deprecated, all new code should use the
3115 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3116 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3117 argument instead of a const uint8_t *buf / int buf_size pair.
3119 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3120 Introduce the av_fifo_space() function.
3122 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3123 Move AVPacket declaration from libavformat/avformat.h to
3124 libavcodec/avcodec.h.
3126 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3127 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3128 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3129 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3130 PIX_FMT_BGR32_1 are now macros.
3131 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3132 Re-sort the enum PixelFormat list accordingly.
3133 This change breaks API/ABI backward compatibility.
3135 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3136 Add the enum PixelFormat values:
3137 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3138 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3140 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3141 The Mersenne Twister PRNG implemented through the av_random* functions
3142 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3145 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3146 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3147 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3148 and av_fifo_realloc2.
3149 In addition, the order of the function arguments of av_fifo_generic_read
3150 was changed to match av_fifo_generic_write.
3151 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3152 applications, they may not use sizeof() or directly access members.
3154 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3155 Introduce a new metadata API (see av_metadata_get() and friends).
3156 The old API is now deprecated and should not be used anymore. This especially
3157 includes the following structure fields:
3158 - AVFormatContext.title
3159 - AVFormatContext.author
3160 - AVFormatContext.copyright
3161 - AVFormatContext.comment
3162 - AVFormatContext.album
3163 - AVFormatContext.year
3164 - AVFormatContext.track
3165 - AVFormatContext.genre
3168 - AVProgram.provider_name
