259 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
260 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
261 (avcodec_send_packet/avcodec_receive_frame) always work with reference
264 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
265 Add av_color_range_from_name(), av_color_primaries_from_name(),

347 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
348 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
349 set the Cuda device handle.
351 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

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

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

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

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

3030 Remove the next field from AVFilter, this is not anymore required.
3032 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3033 Introduce the avfilter_next() function.
3035 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3036 Change the signature of avfilter_register() to make it return an
3037 int. This is required since now the registration operation may fail.
3039 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3040 Make the pixdesc.h API public.
3042 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3043 Add a next field to AVFilter, this is used for simplifying the
3044 registration and management of the registered filters.
3046 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3047 Add a description field to AVFilter.
3049 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3050 Change the interface of avfilter_make_format_list() from

3054 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3055 Make avfilter_get_video_buffer() recursive and add the w and h
3058 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3059 Add w and h fields to AVFilterPic.
3061 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3062 This is now an unsigned int instead of a signed int.
3064 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3065 Add a pts field to AVSubtitle which gives the subtitle packet pts
3066 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3067 not work right without this.
3069 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3070 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3071 major version. Use AV_PKT_FLAG_KEY instead.
3073 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3074 av_lockmgr_register() can be used to register a callback function
3075 that lavc (and in the future, libraries that depend on lavc) can use
3076 to implement mutexes. The application should provide a callback function
3077 that implements the AV_LOCK_* operations described in avcodec.h.
3078 When the lock manager is registered, FFmpeg is guaranteed to behave
3079 correctly in a multi-threaded application.
3081 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3082 av_free_packet() is no longer an inline function. It is now exported.
3084 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3085 Please use NULL instead. This has been supported since r16506
3086 (lavf > 52.23.1, lavc > 52.10.0).
3088 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3089 The old decoding functions are deprecated, all new code should use the
3090 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3091 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3092 argument instead of a const uint8_t *buf / int buf_size pair.
3094 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3095 Introduce the av_fifo_space() function.
3097 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3098 Move AVPacket declaration from libavformat/avformat.h to
3099 libavcodec/avcodec.h.
3101 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3102 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3103 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3104 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3105 PIX_FMT_BGR32_1 are now macros.
3106 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3107 Re-sort the enum PixelFormat list accordingly.
3108 This change breaks API/ABI backward compatibility.
3110 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3111 Add the enum PixelFormat values:
3112 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3113 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3115 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3116 The Mersenne Twister PRNG implemented through the av_random* functions
3117 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3120 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3121 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3122 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3123 and av_fifo_realloc2.
3124 In addition, the order of the function arguments of av_fifo_generic_read
3125 was changed to match av_fifo_generic_write.
3126 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3127 applications, they may not use sizeof() or directly access members.
3129 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3130 Introduce a new metadata API (see av_metadata_get() and friends).
3131 The old API is now deprecated and should not be used anymore. This especially
3132 includes the following structure fields:
3133 - AVFormatContext.title
3134 - AVFormatContext.author
3135 - AVFormatContext.copyright
3136 - AVFormatContext.comment
3137 - AVFormatContext.album
3138 - AVFormatContext.year
3139 - AVFormatContext.track
3140 - AVFormatContext.genre
3143 - AVProgram.provider_name
