256 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
257 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
258 (avcodec_send_packet/avcodec_receive_frame) always work with reference
261 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
262 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

344 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
345 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
346 set the Cuda device handle.
348 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

372 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
373 (via an entry named "rotate"). Use av_stream_get_side_data() with
374 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

376 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
377 to be added to the AVStream.

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

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

612 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
613 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
614 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
615 The default value for this option will change to "ass" at the next major
616 libavcodec version bump.
618 The current default is "ass_with_timings" for compatibility. This means that
619 all subtitles text decoders currently still output ASS with timings printed
620 as strings in the AVSubtitles.rects[N]->ass fields.
622 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
623 timing is limited to a 1/100 time base, so this is relevant for any subtitles
624 format needing a bigger one), ease timing adjustments, and prevents the need
625 of removing the timing from the decoded string yourself. This form is also
626 known as "the Matroska form". The timing information (start time, duration)
627 can be found in the AVSubtitles fields.

3027 Remove the next field from AVFilter, this is not anymore required.
3029 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3030 Introduce the avfilter_next() function.
3032 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3033 Change the signature of avfilter_register() to make it return an
3034 int. This is required since now the registration operation may fail.
3036 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3037 Make the pixdesc.h API public.
3039 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3040 Add a next field to AVFilter, this is used for simplifying the
3041 registration and management of the registered filters.
3043 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3044 Add a description field to AVFilter.
3046 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3047 Change the interface of avfilter_make_format_list() from
3048 avfilter_make_format_list(int n, ...) to
3049 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3051 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3052 Make avfilter_get_video_buffer() recursive and add the w and h
3055 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3056 Add w and h fields to AVFilterPic.
3058 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3059 This is now an unsigned int instead of a signed int.
3061 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3062 Add a pts field to AVSubtitle which gives the subtitle packet pts
3063 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3064 not work right without this.
3066 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3067 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3068 major version. Use AV_PKT_FLAG_KEY instead.
3070 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3071 av_lockmgr_register() can be used to register a callback function
3072 that lavc (and in the future, libraries that depend on lavc) can use
3073 to implement mutexes. The application should provide a callback function
3074 that implements the AV_LOCK_* operations described in avcodec.h.
3075 When the lock manager is registered, FFmpeg is guaranteed to behave
3076 correctly in a multi-threaded application.
3078 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3079 av_free_packet() is no longer an inline function. It is now exported.
3081 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3082 Please use NULL instead. This has been supported since r16506
3083 (lavf > 52.23.1, lavc > 52.10.0).
3085 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3086 The old decoding functions are deprecated, all new code should use the
3087 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3088 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3089 argument instead of a const uint8_t *buf / int buf_size pair.
3091 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3092 Introduce the av_fifo_space() function.
3094 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3095 Move AVPacket declaration from libavformat/avformat.h to
3096 libavcodec/avcodec.h.
3098 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3099 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3100 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3101 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3102 PIX_FMT_BGR32_1 are now macros.
3103 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3104 Re-sort the enum PixelFormat list accordingly.
3105 This change breaks API/ABI backward compatibility.
3107 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3108 Add the enum PixelFormat values:
3109 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3110 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3112 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3113 The Mersenne Twister PRNG implemented through the av_random* functions
3114 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3117 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3118 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3119 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3120 and av_fifo_realloc2.
3121 In addition, the order of the function arguments of av_fifo_generic_read
3122 was changed to match av_fifo_generic_write.
3123 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3124 applications, they may not use sizeof() or directly access members.
3126 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3127 Introduce a new metadata API (see av_metadata_get() and friends).
3128 The old API is now deprecated and should not be used anymore. This especially
3129 includes the following structure fields:
3130 - AVFormatContext.title
3131 - AVFormatContext.author
3132 - AVFormatContext.copyright
3133 - AVFormatContext.comment
3134 - AVFormatContext.album
3135 - AVFormatContext.year
3136 - AVFormatContext.track
3137 - AVFormatContext.genre
3140 - AVProgram.provider_name
