265 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
266 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
267 (avcodec_send_packet/avcodec_receive_frame) always work with reference
270 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
271 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

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

621 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
622 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
623 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
624 The default value for this option will change to "ass" at the next major
625 libavcodec version bump.
627 The current default is "ass_with_timings" for compatibility. This means that
628 all subtitles text decoders currently still output ASS with timings printed
629 as strings in the AVSubtitles.rects[N]->ass fields.
631 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
632 timing is limited to a 1/100 time base, so this is relevant for any subtitles
633 format needing a bigger one), ease timing adjustments, and prevents the need
634 of removing the timing from the decoded string yourself. This form is also
635 known as "the Matroska form". The timing information (start time, duration)
636 can be found in the AVSubtitles fields.

3038 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3039 Introduce the avfilter_next() function.
3041 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3042 Change the signature of avfilter_register() to make it return an
3043 int. This is required since now the registration operation may fail.
3045 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3046 Make the pixdesc.h API public.
3048 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3070 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3071 Add a pts field to AVSubtitle which gives the subtitle packet pts
3072 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3073 not work right without this.
3075 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3076 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3077 major version. Use AV_PKT_FLAG_KEY instead.
3079 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3080 av_lockmgr_register() can be used to register a callback function
3081 that lavc (and in the future, libraries that depend on lavc) can use
3082 to implement mutexes. The application should provide a callback function
3083 that implements the AV_LOCK_* operations described in avcodec.h.
3084 When the lock manager is registered, FFmpeg is guaranteed to behave
3085 correctly in a multi-threaded application.
3087 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3088 av_free_packet() is no longer an inline function. It is now exported.
3090 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3091 Please use NULL instead. This has been supported since r16506
3092 (lavf > 52.23.1, lavc > 52.10.0).
3094 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3095 The old decoding functions are deprecated, all new code should use the
3096 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3097 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3098 argument instead of a const uint8_t *buf / int buf_size pair.
3100 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3101 Introduce the av_fifo_space() function.
3103 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3104 Move AVPacket declaration from libavformat/avformat.h to
3105 libavcodec/avcodec.h.
3107 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3108 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3109 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3110 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3111 PIX_FMT_BGR32_1 are now macros.
3112 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3113 Re-sort the enum PixelFormat list accordingly.
3114 This change breaks API/ABI backward compatibility.
3116 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3117 Add the enum PixelFormat values:
3118 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3119 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3121 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3122 The Mersenne Twister PRNG implemented through the av_random* functions
3123 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3126 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3127 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3128 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3129 and av_fifo_realloc2.
3130 In addition, the order of the function arguments of av_fifo_generic_read
3131 was changed to match av_fifo_generic_write.
3132 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3133 applications, they may not use sizeof() or directly access members.
3135 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3136 Introduce a new metadata API (see av_metadata_get() and friends).
3137 The old API is now deprecated and should not be used anymore. This especially
3138 includes the following structure fields:
3139 - AVFormatContext.title
3140 - AVFormatContext.author
3141 - AVFormatContext.copyright
3142 - AVFormatContext.comment
3143 - AVFormatContext.album
3144 - AVFormatContext.year
3145 - AVFormatContext.track
3146 - AVFormatContext.genre
3149 - AVProgram.provider_name
