Returns the SDI format. Might be different from capture image format.

(

unsigned int

ihavealready

)

const

int niftk::NVidiaSDIDataSourceImpl::GetRGBAImage	(	unsigned int	sequencenumber,
		IplImage *	targetbuffer
	)

targetbuffer needs to have the correct(!) size to fit all channels stacked together. Try something like cvCreateImage(cvSize(GetCaptureFormat().first, GetCaptureFormat().second * numstreams), IPL_DEPTH_8U, 4).

Returns

number of channels, or zero in case of some error.
