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

350 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
351 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
352 set the Cuda device handle.
354 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

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

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

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

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

3032 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3033 Remove the next field from AVFilter, this is not anymore required.
3035 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3036 Introduce the avfilter_next() function.
3038 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3039 Change the signature of avfilter_register() to make it return an
3040 int. This is required since now the registration operation may fail.
3042 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3043 Make the pixdesc.h API public.
3045 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3046 Add a next field to AVFilter, this is used for simplifying the
3047 registration and management of the registered filters.
3049 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3050 Add a description field to AVFilter.
3052 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3053 Change the interface of avfilter_make_format_list() from

3057 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3058 Make avfilter_get_video_buffer() recursive and add the w and h
3061 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3062 Add w and h fields to AVFilterPic.
3064 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3065 This is now an unsigned int instead of a signed int.
3067 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3068 Add a pts field to AVSubtitle which gives the subtitle packet pts
3069 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3070 not work right without this.
3072 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3073 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3074 major version. Use AV_PKT_FLAG_KEY instead.
3076 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3077 av_lockmgr_register() can be used to register a callback function
3078 that lavc (and in the future, libraries that depend on lavc) can use
3079 to implement mutexes. The application should provide a callback function
3080 that implements the AV_LOCK_* operations described in avcodec.h.
3081 When the lock manager is registered, FFmpeg is guaranteed to behave
3082 correctly in a multi-threaded application.
3084 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3085 av_free_packet() is no longer an inline function. It is now exported.
3087 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3088 Please use NULL instead. This has been supported since r16506
3089 (lavf > 52.23.1, lavc > 52.10.0).
3091 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3092 The old decoding functions are deprecated, all new code should use the
3093 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3094 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3095 argument instead of a const uint8_t *buf / int buf_size pair.
3097 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3098 Introduce the av_fifo_space() function.
3100 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3101 Move AVPacket declaration from libavformat/avformat.h to
3102 libavcodec/avcodec.h.
3104 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3105 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3106 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3107 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3108 PIX_FMT_BGR32_1 are now macros.
3109 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3110 Re-sort the enum PixelFormat list accordingly.
3111 This change breaks API/ABI backward compatibility.
3113 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3114 Add the enum PixelFormat values:
3115 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3116 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3118 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3119 The Mersenne Twister PRNG implemented through the av_random* functions
3120 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3123 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3124 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3125 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3126 and av_fifo_realloc2.
3127 In addition, the order of the function arguments of av_fifo_generic_read
3128 was changed to match av_fifo_generic_write.
3129 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3130 applications, they may not use sizeof() or directly access members.
3132 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3133 Introduce a new metadata API (see av_metadata_get() and friends).
3134 The old API is now deprecated and should not be used anymore. This especially
3135 includes the following structure fields:
3136 - AVFormatContext.title
3137 - AVFormatContext.author
3138 - AVFormatContext.copyright
3139 - AVFormatContext.comment
3140 - AVFormatContext.album
3141 - AVFormatContext.year
3142 - AVFormatContext.track
3143 - AVFormatContext.genre
3146 - AVProgram.provider_name
