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

393 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
394 (via an entry named "rotate"). Use av_stream_get_side_data() with
395 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
396 av_display_rotation_get(). The same is done for muxing. Instead of adding a
397 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
398 to be added to the AVStream.

503 Decoders now export the frame timestamp as AVFrame.pts. It was
504 previously exported as AVFrame.pkt_pts, which is now deprecated.
506 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

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

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

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

3020 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
3022 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
3023 Add avfilter_add_colorspace().
3025 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
3026 Add av_match_ext(), it should be used in place of match_ext().
3028 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
3029 Add av_guess_format(), it should be used in place of guess_format().
3031 2009-12-13 - a181981 - lavf 52.43.0 - metadata API
3032 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
3033 AV_METADATA_DONT_STRDUP_VAL.
3035 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API
3038 2009-12-13 - 02b398e - lavc 52.42.0 - AVStream

3042 Introduce the av_bmg_next() function.
3044 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
3045 Add a slice_dir parameter to avfilter_draw_slice().
3047 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3048 Remove the next field from AVFilter, this is not anymore required.
3050 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3051 Introduce the avfilter_next() function.
3053 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3054 Change the signature of avfilter_register() to make it return an
3055 int. This is required since now the registration operation may fail.
3057 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3058 Make the pixdesc.h API public.
3060 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3061 Add a next field to AVFilter, this is used for simplifying the
3062 registration and management of the registered filters.
3064 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3065 Add a description field to AVFilter.
3067 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3068 Change the interface of avfilter_make_format_list() from

3072 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3073 Make avfilter_get_video_buffer() recursive and add the w and h
3076 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3077 Add w and h fields to AVFilterPic.
3079 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3080 This is now an unsigned int instead of a signed int.
3082 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3083 Add a pts field to AVSubtitle which gives the subtitle packet pts
3084 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3085 not work right without this.
3087 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3088 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3089 major version. Use AV_PKT_FLAG_KEY instead.
3091 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3092 av_lockmgr_register() can be used to register a callback function
3093 that lavc (and in the future, libraries that depend on lavc) can use
3094 to implement mutexes. The application should provide a callback function
3095 that implements the AV_LOCK_* operations described in avcodec.h.
3096 When the lock manager is registered, FFmpeg is guaranteed to behave
3097 correctly in a multi-threaded application.
3099 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3100 av_free_packet() is no longer an inline function. It is now exported.
3102 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3103 Please use NULL instead. This has been supported since r16506
3104 (lavf > 52.23.1, lavc > 52.10.0).
3106 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3107 The old decoding functions are deprecated, all new code should use the
3108 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3109 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3110 argument instead of a const uint8_t *buf / int buf_size pair.
3112 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3113 Introduce the av_fifo_space() function.
3115 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3116 Move AVPacket declaration from libavformat/avformat.h to
3117 libavcodec/avcodec.h.
3119 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3120 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3121 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3122 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3123 PIX_FMT_BGR32_1 are now macros.
3124 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3125 Re-sort the enum PixelFormat list accordingly.
3126 This change breaks API/ABI backward compatibility.
3128 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3129 Add the enum PixelFormat values:
3130 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3131 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3133 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3134 The Mersenne Twister PRNG implemented through the av_random* functions
3135 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3138 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3139 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3140 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3141 and av_fifo_realloc2.
3142 In addition, the order of the function arguments of av_fifo_generic_read
3143 was changed to match av_fifo_generic_write.
3144 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3145 applications, they may not use sizeof() or directly access members.
3147 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3148 Introduce a new metadata API (see av_metadata_get() and friends).
3149 The old API is now deprecated and should not be used anymore. This especially
3150 includes the following structure fields:
3151 - AVFormatContext.title
3152 - AVFormatContext.author
3153 - AVFormatContext.copyright
3154 - AVFormatContext.comment
3155 - AVFormatContext.album
3156 - AVFormatContext.year
3157 - AVFormatContext.track
3158 - AVFormatContext.genre
3161 - AVProgram.provider_name
