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

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

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

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

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

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

1943 For audio formats with fixed frame size, the last frame
1944 no longer needs to be padded with silence, libavcodec
1945 will handle this internally (effectively all encoders
1946 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3091 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3092 Introduce the avfilter_next() function.
3094 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3095 Change the signature of avfilter_register() to make it return an
3096 int. This is required since now the registration operation may fail.
3098 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3099 Make the pixdesc.h API public.
3101 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3123 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3124 Add a pts field to AVSubtitle which gives the subtitle packet pts
3125 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3126 not work right without this.
3128 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3129 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3130 major version. Use AV_PKT_FLAG_KEY instead.
3132 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3133 av_lockmgr_register() can be used to register a callback function
3134 that lavc (and in the future, libraries that depend on lavc) can use
3135 to implement mutexes. The application should provide a callback function
3136 that implements the AV_LOCK_* operations described in avcodec.h.
3137 When the lock manager is registered, FFmpeg is guaranteed to behave
3138 correctly in a multi-threaded application.
3140 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3141 av_free_packet() is no longer an inline function. It is now exported.
3143 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3144 Please use NULL instead. This has been supported since r16506
3145 (lavf > 52.23.1, lavc > 52.10.0).
3147 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3148 The old decoding functions are deprecated, all new code should use the
3149 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3150 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3151 argument instead of a const uint8_t *buf / int buf_size pair.
3153 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3154 Introduce the av_fifo_space() function.
3156 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3157 Move AVPacket declaration from libavformat/avformat.h to
3158 libavcodec/avcodec.h.
3160 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3161 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3162 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3163 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3164 PIX_FMT_BGR32_1 are now macros.
3165 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3166 Re-sort the enum PixelFormat list accordingly.
3167 This change breaks API/ABI backward compatibility.
3169 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3170 Add the enum PixelFormat values:
3171 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3172 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3174 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3175 The Mersenne Twister PRNG implemented through the av_random* functions
3176 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3179 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3180 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3181 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3182 and av_fifo_realloc2.
3183 In addition, the order of the function arguments of av_fifo_generic_read
3184 was changed to match av_fifo_generic_write.
3185 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3186 applications, they may not use sizeof() or directly access members.
3188 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3189 Introduce a new metadata API (see av_metadata_get() and friends).
3190 The old API is now deprecated and should not be used anymore. This especially
3191 includes the following structure fields:
3192 - AVFormatContext.title
3193 - AVFormatContext.author
3194 - AVFormatContext.copyright
3195 - AVFormatContext.comment
3196 - AVFormatContext.album
3197 - AVFormatContext.year
3198 - AVFormatContext.track
3199 - AVFormatContext.genre
3202 - AVProgram.provider_name
