402 2017-05-05 - c0f17a905f - lavc 57.94.100 - avcodec.h
403 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
404 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
405 set the Cuda device handle.

431 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
432 (via an entry named "rotate"). Use av_stream_get_side_data() with
433 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
434 av_display_rotation_get(). The same is done for muxing. Instead of adding a
435 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
436 to be added to the AVStream.

541 Decoders now export the frame timestamp as AVFrame.pts. It was
542 previously exported as AVFrame.pkt_pts, which is now deprecated.
544 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
545 and not the codec timebase.

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

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

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

1940 For audio formats with fixed frame size, the last frame
1941 no longer needs to be padded with silence, libavcodec
1942 will handle this internally (effectively all encoders
1943 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3088 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3089 Introduce the avfilter_next() function.
3091 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3092 Change the signature of avfilter_register() to make it return an
3093 int. This is required since now the registration operation may fail.
3095 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3096 Make the pixdesc.h API public.
3098 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3120 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3121 Add a pts field to AVSubtitle which gives the subtitle packet pts
3122 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3123 not work right without this.
3125 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3126 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3127 major version. Use AV_PKT_FLAG_KEY instead.
3129 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3130 av_lockmgr_register() can be used to register a callback function
3131 that lavc (and in the future, libraries that depend on lavc) can use
3132 to implement mutexes. The application should provide a callback function
3133 that implements the AV_LOCK_* operations described in avcodec.h.
3134 When the lock manager is registered, FFmpeg is guaranteed to behave
3135 correctly in a multi-threaded application.
3137 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3138 av_free_packet() is no longer an inline function. It is now exported.
3140 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3141 Please use NULL instead. This has been supported since r16506
3142 (lavf > 52.23.1, lavc > 52.10.0).
3144 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3145 The old decoding functions are deprecated, all new code should use the
3146 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3147 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3148 argument instead of a const uint8_t *buf / int buf_size pair.
3150 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3151 Introduce the av_fifo_space() function.
3153 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3154 Move AVPacket declaration from libavformat/avformat.h to
3155 libavcodec/avcodec.h.
3157 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3158 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3159 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3160 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3161 PIX_FMT_BGR32_1 are now macros.
3162 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3163 Re-sort the enum PixelFormat list accordingly.
3164 This change breaks API/ABI backward compatibility.
3166 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3167 Add the enum PixelFormat values:
3168 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3169 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3171 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3172 The Mersenne Twister PRNG implemented through the av_random* functions
3173 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3176 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3177 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3178 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3179 and av_fifo_realloc2.
3180 In addition, the order of the function arguments of av_fifo_generic_read
3181 was changed to match av_fifo_generic_write.
3182 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3183 applications, they may not use sizeof() or directly access members.
3185 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3186 Introduce a new metadata API (see av_metadata_get() and friends).
3187 The old API is now deprecated and should not be used anymore. This especially
3188 includes the following structure fields:
3189 - AVFormatContext.title
3190 - AVFormatContext.author
3191 - AVFormatContext.copyright
3192 - AVFormatContext.comment
3193 - AVFormatContext.album
3194 - AVFormatContext.year
3195 - AVFormatContext.track
3196 - AVFormatContext.genre
3199 - AVProgram.provider_name
