157 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
159 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h

166 providing more functionality, is faster and has higher accuracy.
168 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

227 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
228 (avcodec_send_packet/avcodec_receive_frame) always work with reference
231 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
232 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

314 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
315 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
316 set the Cuda device handle.
318 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

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

382 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
383 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
384 native decoder format. (The default value is not changed.)

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

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

582 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
583 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
584 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
585 The default value for this option will change to "ass" at the next major
586 libavcodec version bump.
588 The current default is "ass_with_timings" for compatibility. This means that
589 all subtitles text decoders currently still output ASS with timings printed
590 as strings in the AVSubtitles.rects[N]->ass fields.
592 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
593 timing is limited to a 1/100 time base, so this is relevant for any subtitles
594 format needing a bigger one), ease timing adjustments, and prevents the need
595 of removing the timing from the decoded string yourself. This form is also
596 known as "the Matroska form". The timing information (start time, duration)
597 can be found in the AVSubtitles fields.

3019 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3021 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3022 Make avfilter_get_video_buffer() recursive and add the w and h
3025 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3026 Add w and h fields to AVFilterPic.
3028 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3029 This is now an unsigned int instead of a signed int.
3031 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3032 Add a pts field to AVSubtitle which gives the subtitle packet pts
3033 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3034 not work right without this.
3036 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3037 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3038 major version. Use AV_PKT_FLAG_KEY instead.
3040 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3041 av_lockmgr_register() can be used to register a callback function
3042 that lavc (and in the future, libraries that depend on lavc) can use
3043 to implement mutexes. The application should provide a callback function
3044 that implements the AV_LOCK_* operations described in avcodec.h.
3045 When the lock manager is registered, FFmpeg is guaranteed to behave
3046 correctly in a multi-threaded application.
3048 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3049 av_free_packet() is no longer an inline function. It is now exported.
3051 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3052 Please use NULL instead. This has been supported since r16506
3053 (lavf > 52.23.1, lavc > 52.10.0).
3055 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3056 The old decoding functions are deprecated, all new code should use the
3057 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3058 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3059 argument instead of a const uint8_t *buf / int buf_size pair.
3061 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3062 Introduce the av_fifo_space() function.
3064 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3065 Move AVPacket declaration from libavformat/avformat.h to
3066 libavcodec/avcodec.h.
3068 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3069 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3070 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3071 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3072 PIX_FMT_BGR32_1 are now macros.
3073 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3074 Re-sort the enum PixelFormat list accordingly.
3075 This change breaks API/ABI backward compatibility.
3077 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3078 Add the enum PixelFormat values:
3079 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3080 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3082 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3083 The Mersenne Twister PRNG implemented through the av_random* functions
3084 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3087 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3088 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3089 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3090 and av_fifo_realloc2.
3091 In addition, the order of the function arguments of av_fifo_generic_read
3092 was changed to match av_fifo_generic_write.
3093 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3094 applications, they may not use sizeof() or directly access members.
3096 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3097 Introduce a new metadata API (see av_metadata_get() and friends).
3098 The old API is now deprecated and should not be used anymore. This especially
3099 includes the following structure fields:
3100 - AVFormatContext.title
3101 - AVFormatContext.author
3102 - AVFormatContext.copyright
3103 - AVFormatContext.comment
3104 - AVFormatContext.album
3105 - AVFormatContext.year
3106 - AVFormatContext.track
3107 - AVFormatContext.genre
3110 - AVProgram.provider_name
