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

420 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
421 (via an entry named "rotate"). Use av_stream_get_side_data() with
422 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
423 av_display_rotation_get(). The same is done for muxing. Instead of adding a
424 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
425 to be added to the AVStream.

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

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

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

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

1872 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1873 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1929 For audio formats with fixed frame size, the last frame
1930 no longer needs to be padded with silence, libavcodec
1931 will handle this internally (effectively all encoders
1932 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3077 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3078 Introduce the avfilter_next() function.
3080 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3081 Change the signature of avfilter_register() to make it return an
3082 int. This is required since now the registration operation may fail.

3085 Make the pixdesc.h API public.
3087 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3092 Add a description field to AVFilter.
3094 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3095 Change the interface of avfilter_make_format_list() from

3106 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

3109 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3110 Add a pts field to AVSubtitle which gives the subtitle packet pts
3111 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3112 not work right without this.
3114 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3115 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3116 major version. Use AV_PKT_FLAG_KEY instead.
3118 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3119 av_lockmgr_register() can be used to register a callback function
3120 that lavc (and in the future, libraries that depend on lavc) can use
3121 to implement mutexes. The application should provide a callback function
3122 that implements the AV_LOCK_* operations described in avcodec.h.
3123 When the lock manager is registered, FFmpeg is guaranteed to behave
3124 correctly in a multi-threaded application.
3126 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3127 av_free_packet() is no longer an inline function. It is now exported.
3129 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3130 Please use NULL instead. This has been supported since r16506
3131 (lavf > 52.23.1, lavc > 52.10.0).
3133 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3134 The old decoding functions are deprecated, all new code should use the
3135 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3136 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3137 argument instead of a const uint8_t *buf / int buf_size pair.
3139 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3140 Introduce the av_fifo_space() function.
3142 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3143 Move AVPacket declaration from libavformat/avformat.h to
3144 libavcodec/avcodec.h.
3146 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3147 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3148 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3149 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3150 PIX_FMT_BGR32_1 are now macros.
3151 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3152 Re-sort the enum PixelFormat list accordingly.
3153 This change breaks API/ABI backward compatibility.
3155 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3156 Add the enum PixelFormat values:
3157 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3158 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3160 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3161 The Mersenne Twister PRNG implemented through the av_random* functions
3162 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3165 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3166 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3167 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3168 and av_fifo_realloc2.
3169 In addition, the order of the function arguments of av_fifo_generic_read
3170 was changed to match av_fifo_generic_write.
3171 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3172 applications, they may not use sizeof() or directly access members.
3174 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3175 Introduce a new metadata API (see av_metadata_get() and friends).
3176 The old API is now deprecated and should not be used anymore. This especially
3177 includes the following structure fields:
3178 - AVFormatContext.title
3179 - AVFormatContext.author
3180 - AVFormatContext.copyright
3181 - AVFormatContext.comment
3182 - AVFormatContext.album
3183 - AVFormatContext.year
3184 - AVFormatContext.track
3185 - AVFormatContext.genre
3188 - AVProgram.provider_name
