231 is over, the old "timeout" option will be removed, and "stimeout" will be
232 renamed to "stimeout" (the "timeout" option will essentially change semantics).
234 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h

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

412 parameter type to size_t at next major bump.
414 2017-05-05 - c0f17a905f - lavc 57.94.100 - avcodec.h
415 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
416 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
417 set the Cuda device handle.

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

483 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
484 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the

489 in AVFrame, AVCodecContext, and AVFormatContext that were previously
490 documented as "no direct access" allowed.

508 Deprecate struct vaapi_context and the vaapi.h installed header.

553 Decoders now export the frame timestamp as AVFrame.pts. It was
554 previously exported as AVFrame.pkt_pts, which is now deprecated.
556 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
557 and not the codec timebase.

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

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

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

1868 Add avcodec_free_frame(). This function must now
1869 be used for freeing an AVFrame.
1871 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h
1872 Added AV_CH_LOW_FREQUENCY_2 channel mask value.
1874 2012-09-04 - b21b5b0 / 686a329 - lavu 51.71.100 / 51.40.0 - opt.h

1895 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1896 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1897 Note that this can break user code that includes avcodec.h and uses the
1898 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1926 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1927 should now be used instead of accessing AVFilterPad members
1930 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1931 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1932 and av_channel_layout_extract_channel().

1951 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1952 For audio formats with fixed frame size, the last frame
1953 no longer needs to be padded with silence, libavcodec
1954 will handle this internally (effectively all encoders
1955 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3100 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3101 Introduce the avfilter_next() function.
3103 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3104 Change the signature of avfilter_register() to make it return an
3105 int. This is required since now the registration operation may fail.
3107 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3108 Make the pixdesc.h API public.

3132 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3133 Add a pts field to AVSubtitle which gives the subtitle packet pts
3134 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3135 not work right without this.
3137 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3138 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3139 major version. Use AV_PKT_FLAG_KEY instead.
3141 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3142 av_lockmgr_register() can be used to register a callback function
3143 that lavc (and in the future, libraries that depend on lavc) can use
3144 to implement mutexes. The application should provide a callback function
3145 that implements the AV_LOCK_* operations described in avcodec.h.
3146 When the lock manager is registered, FFmpeg is guaranteed to behave
3147 correctly in a multi-threaded application.
3149 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3150 av_free_packet() is no longer an inline function. It is now exported.
3152 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3153 Please use NULL instead. This has been supported since r16506
3154 (lavf > 52.23.1, lavc > 52.10.0).
3156 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3157 The old decoding functions are deprecated, all new code should use the
3158 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3159 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3160 argument instead of a const uint8_t *buf / int buf_size pair.
3162 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3163 Introduce the av_fifo_space() function.
3165 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3166 Move AVPacket declaration from libavformat/avformat.h to
3167 libavcodec/avcodec.h.
3169 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3170 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3171 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3172 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3173 PIX_FMT_BGR32_1 are now macros.
3174 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3175 Re-sort the enum PixelFormat list accordingly.
3176 This change breaks API/ABI backward compatibility.
3178 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3179 Add the enum PixelFormat values:
3180 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3181 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3183 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3184 The Mersenne Twister PRNG implemented through the av_random* functions
3185 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3188 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3189 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3190 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3191 and av_fifo_realloc2.
3192 In addition, the order of the function arguments of av_fifo_generic_read
3193 was changed to match av_fifo_generic_write.
3194 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3195 applications, they may not use sizeof() or directly access members.
3197 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3198 Introduce a new metadata API (see av_metadata_get() and friends).
3199 The old API is now deprecated and should not be used anymore. This especially
3200 includes the following structure fields:
3201 - AVFormatContext.title
3202 - AVFormatContext.author
3203 - AVFormatContext.copyright
3204 - AVFormatContext.comment
3205 - AVFormatContext.album
3206 - AVFormatContext.year
3207 - AVFormatContext.track
3208 - AVFormatContext.genre
3211 - AVProgram.provider_name
