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

412 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
413 (via an entry named "rotate"). Use av_stream_get_side_data() with
414 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
415 av_display_rotation_get(). The same is done for muxing. Instead of adding a
416 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
417 to be added to the AVStream.

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

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

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

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

1864 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1865 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1895 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1896 should now be used instead of accessing AVFilterPad members
1899 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1900 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1901 and av_channel_layout_extract_channel().

1920 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1921 For audio formats with fixed frame size, the last frame
1922 no longer needs to be padded with silence, libavcodec
1923 will handle this internally (effectively all encoders
1924 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3038 Change the avfilter_add_colorspace() signature, make it accept an
3039 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
3041 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
3042 Add avfilter_add_colorspace().
3044 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
3045 Add av_match_ext(), it should be used in place of match_ext().

3066 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3067 Remove the next field from AVFilter, this is not anymore required.
3069 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3070 Introduce the avfilter_next() function.
3072 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3073 Change the signature of avfilter_register() to make it return an
3074 int. This is required since now the registration operation may fail.
3076 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3077 Make the pixdesc.h API public.
3079 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3084 Add a description field to AVFilter.
3086 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3087 Change the interface of avfilter_make_format_list() from

3091 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3092 Make avfilter_get_video_buffer() recursive and add the w and h
3095 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3096 Add w and h fields to AVFilterPic.
3098 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3099 This is now an unsigned int instead of a signed int.
3101 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3102 Add a pts field to AVSubtitle which gives the subtitle packet pts
3103 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3104 not work right without this.
3106 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3107 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3108 major version. Use AV_PKT_FLAG_KEY instead.
3110 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3111 av_lockmgr_register() can be used to register a callback function
3112 that lavc (and in the future, libraries that depend on lavc) can use
3113 to implement mutexes. The application should provide a callback function
3114 that implements the AV_LOCK_* operations described in avcodec.h.
3115 When the lock manager is registered, FFmpeg is guaranteed to behave
3116 correctly in a multi-threaded application.
3118 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3119 av_free_packet() is no longer an inline function. It is now exported.
3121 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3122 Please use NULL instead. This has been supported since r16506
3123 (lavf > 52.23.1, lavc > 52.10.0).
3125 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3126 The old decoding functions are deprecated, all new code should use the
3127 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3128 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3129 argument instead of a const uint8_t *buf / int buf_size pair.
3131 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3132 Introduce the av_fifo_space() function.
3134 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3135 Move AVPacket declaration from libavformat/avformat.h to
3136 libavcodec/avcodec.h.
3138 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3139 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3140 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3141 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3142 PIX_FMT_BGR32_1 are now macros.
3143 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3144 Re-sort the enum PixelFormat list accordingly.
3145 This change breaks API/ABI backward compatibility.
3147 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3148 Add the enum PixelFormat values:
3149 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3150 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3152 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3153 The Mersenne Twister PRNG implemented through the av_random* functions
3154 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3157 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3158 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3159 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3160 and av_fifo_realloc2.
3161 In addition, the order of the function arguments of av_fifo_generic_read
3162 was changed to match av_fifo_generic_write.
3163 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3164 applications, they may not use sizeof() or directly access members.
3166 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3167 Introduce a new metadata API (see av_metadata_get() and friends).
3168 The old API is now deprecated and should not be used anymore. This especially
3169 includes the following structure fields:
3170 - AVFormatContext.title
3171 - AVFormatContext.author
3172 - AVFormatContext.copyright
3173 - AVFormatContext.comment
3174 - AVFormatContext.album
3175 - AVFormatContext.year
3176 - AVFormatContext.track
3177 - AVFormatContext.genre
3180 - AVProgram.provider_name
