Parameters

in_streamstyping.Iterable[Stream]: Transmitted to cutcutcodec.core.classes.filter.Filter. About the overlaping portions, if the stream is an audio stream, a simple addition is performed but if the stream is a video stream, the frames are combined like a superposition of semi-transparent windows.
