227 is over, the old "timeout" option will be removed, and "stimeout" will be
228 renamed to "stimeout" (the "timeout" option will essentially change semantics).
230 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h

263 providing more functionality, is faster and has higher accuracy.

365 DXVA2 and D3D11 hardware accelerated decoding now supports the new hwaccel API,
366 which can create the decoder context and allocate hardware frame automatically.
367 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
368 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

410 2017-05-05 - c0f17a905f - lavc 57.94.100 - avcodec.h
411 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
412 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
413 set the Cuda device handle.

439 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
440 (via an entry named "rotate"). Use av_stream_get_side_data() with
441 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
442 av_display_rotation_get(). The same is done for muxing. Instead of adding a
443 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
444 to be added to the AVStream.

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

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

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

679 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
680 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
681 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
682 The default value for this option will change to "ass" at the next major
683 libavcodec version bump.
685 The current default is "ass_with_timings" for compatibility. This means that
686 all subtitles text decoders currently still output ASS with timings printed
687 as strings in the AVSubtitles.rects[N]->ass fields.
689 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
690 timing is limited to a 1/100 time base, so this is relevant for any subtitles
691 format needing a bigger one), ease timing adjustments, and prevents the need
692 of removing the timing from the decoded string yourself. This form is also
693 known as "the Matroska form". The timing information (start time, duration)
694 can be found in the AVSubtitles fields.

1865 be used for freeing an AVFrame.

1868 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

1891 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1892 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1893 Note that this can break user code that includes avcodec.h and uses the
1894 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1922 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1923 should now be used instead of accessing AVFilterPad members

1947 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1948 For audio formats with fixed frame size, the last frame
1949 no longer needs to be padded with silence, libavcodec
1950 will handle this internally (effectively all encoders
1951 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3096 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3097 Introduce the avfilter_next() function.
3099 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3100 Change the signature of avfilter_register() to make it return an
3101 int. This is required since now the registration operation may fail.

3104 Make the pixdesc.h API public.
3106 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3128 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3129 Add a pts field to AVSubtitle which gives the subtitle packet pts
3130 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3133 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3134 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3135 major version. Use AV_PKT_FLAG_KEY instead.
3137 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3138 av_lockmgr_register() can be used to register a callback function
3139 that lavc (and in the future, libraries that depend on lavc) can use
3140 to implement mutexes. The application should provide a callback function
3141 that implements the AV_LOCK_* operations described in avcodec.h.
3142 When the lock manager is registered, FFmpeg is guaranteed to behave
3143 correctly in a multi-threaded application.
3145 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3146 av_free_packet() is no longer an inline function. It is now exported.
3148 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3149 Please use NULL instead. This has been supported since r16506
3150 (lavf > 52.23.1, lavc > 52.10.0).
3152 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3153 The old decoding functions are deprecated, all new code should use the
3154 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3155 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3156 argument instead of a const uint8_t *buf / int buf_size pair.
3158 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3159 Introduce the av_fifo_space() function.
3161 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3162 Move AVPacket declaration from libavformat/avformat.h to
3163 libavcodec/avcodec.h.
3165 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3166 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3167 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3168 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3169 PIX_FMT_BGR32_1 are now macros.
3170 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3171 Re-sort the enum PixelFormat list accordingly.
3172 This change breaks API/ABI backward compatibility.
3174 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3175 Add the enum PixelFormat values:
3176 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3177 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3179 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3180 The Mersenne Twister PRNG implemented through the av_random* functions
3181 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3184 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3185 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3186 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3187 and av_fifo_realloc2.
3188 In addition, the order of the function arguments of av_fifo_generic_read
3189 was changed to match av_fifo_generic_write.
3190 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3191 applications, they may not use sizeof() or directly access members.
3193 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3194 Introduce a new metadata API (see av_metadata_get() and friends).
3195 The old API is now deprecated and should not be used anymore. This especially
3196 includes the following structure fields:
3197 - AVFormatContext.title
3198 - AVFormatContext.author
3199 - AVFormatContext.copyright
3200 - AVFormatContext.comment
3201 - AVFormatContext.album
3202 - AVFormatContext.year
3203 - AVFormatContext.track
3204 - AVFormatContext.genre
3207 - AVProgram.provider_name
