248 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
249 (avcodec_send_packet/avcodec_receive_frame) always work with reference
252 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
253 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

363 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
364 (via an entry named "rotate"). Use av_stream_get_side_data() with
365 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
366 av_display_rotation_get(). The same is done for muxing. Instead of adding a
367 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
368 to be added to the AVStream.

383 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
384 bump, and libavformat will behave as if it were always set.
385 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().

527 Fix accidental ABI breakage in AVFilterContext.
528 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
530 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
531 compatible with lavfi>=6.47.100. Potentially also affects other users of

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

603 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
604 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
605 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
606 The default value for this option will change to "ass" at the next major
607 libavcodec version bump.
609 The current default is "ass_with_timings" for compatibility. This means that
610 all subtitles text decoders currently still output ASS with timings printed
611 as strings in the AVSubtitles.rects[N]->ass fields.
613 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
614 timing is limited to a 1/100 time base, so this is relevant for any subtitles
615 format needing a bigger one), ease timing adjustments, and prevents the need
616 of removing the timing from the decoded string yourself. This form is also
617 known as "the Matroska form". The timing information (start time, duration)
618 can be found in the AVSubtitles fields.

3017 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3018 Remove the next field from AVFilter, this is not anymore required.
3020 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3021 Introduce the avfilter_next() function.
3023 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3024 Change the signature of avfilter_register() to make it return an
3025 int. This is required since now the registration operation may fail.
3027 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3028 Make the pixdesc.h API public.
3030 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3031 Add a next field to AVFilter, this is used for simplifying the
3032 registration and management of the registered filters.
3034 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3035 Add a description field to AVFilter.
3037 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3038 Change the interface of avfilter_make_format_list() from
3039 avfilter_make_format_list(int n, ...) to
3040 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3042 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3043 Make avfilter_get_video_buffer() recursive and add the w and h
3046 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3047 Add w and h fields to AVFilterPic.
3049 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3050 This is now an unsigned int instead of a signed int.
3052 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3053 Add a pts field to AVSubtitle which gives the subtitle packet pts
3054 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3055 not work right without this.
3057 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3058 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3059 major version. Use AV_PKT_FLAG_KEY instead.
3061 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3062 av_lockmgr_register() can be used to register a callback function
3063 that lavc (and in the future, libraries that depend on lavc) can use
3064 to implement mutexes. The application should provide a callback function
3065 that implements the AV_LOCK_* operations described in avcodec.h.
3066 When the lock manager is registered, FFmpeg is guaranteed to behave
3067 correctly in a multi-threaded application.
3069 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3070 av_free_packet() is no longer an inline function. It is now exported.
3072 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3073 Please use NULL instead. This has been supported since r16506
3074 (lavf > 52.23.1, lavc > 52.10.0).
3076 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3077 The old decoding functions are deprecated, all new code should use the
3078 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3079 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3080 argument instead of a const uint8_t *buf / int buf_size pair.
3082 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3083 Introduce the av_fifo_space() function.
3085 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3086 Move AVPacket declaration from libavformat/avformat.h to
3087 libavcodec/avcodec.h.
3089 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3090 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3091 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3092 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3093 PIX_FMT_BGR32_1 are now macros.
3094 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3095 Re-sort the enum PixelFormat list accordingly.
3096 This change breaks API/ABI backward compatibility.
3098 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3099 Add the enum PixelFormat values:
3100 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3101 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3103 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3104 The Mersenne Twister PRNG implemented through the av_random* functions
3105 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3108 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3109 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3110 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3111 and av_fifo_realloc2.
3112 In addition, the order of the function arguments of av_fifo_generic_read
3113 was changed to match av_fifo_generic_write.
3114 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3115 applications, they may not use sizeof() or directly access members.
3117 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3118 Introduce a new metadata API (see av_metadata_get() and friends).
3119 The old API is now deprecated and should not be used anymore. This especially
3120 includes the following structure fields:
3121 - AVFormatContext.title
3122 - AVFormatContext.author
3123 - AVFormatContext.copyright
3124 - AVFormatContext.comment
3125 - AVFormatContext.album
3126 - AVFormatContext.year
3127 - AVFormatContext.track
3128 - AVFormatContext.genre
3131 - AVProgram.provider_name
