![]() Output even potentially corrupted frames. Its primary use is for regression testing.Īic Apply H263 advanced intra coding / mpeg4 ac prediction. ThisĮnsures that file and data checksums are reproducible and match between platforms. ![]() Only write platform-, build- and time-independent data. Place global headers in extradata instead of every keyframe. Input bitstream might be randomly truncated.ĭon't output frames whose parameters differ from first decoded frame in stream.Įrror AVERROR_INPUT_CHANGED is returned when a frame is dropped. Use internal 2pass ratecontrol in second pass mode. Use internal 2pass ratecontrol in first pass mode. Mv4 Use four motion vector by macroblock (mpeg4). Lowering tolerance too much has an adverse effectįlags flags ( decoding/encoding,audio,video,subtitles ) How far ratecontrol is willing to deviate from the target average bitrate value. ![]() In 1-pass mode, bitrate tolerance specifies Value explicitly in the "AVCodecContext" options or using the libavutil/opt.h API for Options may be set by specifying - option value in the FFmpeg tools, or by setting the Also some options are meant only for decoding or encoding. Nonsensical or ignored by another, so you need to be aware of the meaning of the specified Sometimes, a global option may only affect a specific kind of codec, and may be In addition each codec may support so-called private options, which are specific Libavcodec provides some generic global options, which can be set on all the encoders andĭecoders. ![]() This document describes the codecs (decoders and encoders) provided by the libavcodec ![]()
