Therefor this indication will be very reliable. Some image sources
such as a videorecorder tend to not having a stable timing. For such
devices it might be possible, that the returnvalue 3 will never be

Number of Processed Digitized Images
With the pciGrabber-4x4, it is possible to count the number of
digitized images. The following two functions are used for this
purpose:
These functions are not compatible with the pciGrabber-4.
BYTE Get_CaptureCounter (WORD nDevNo)
return value: Number of grabbed fields module 256
The function returns the number of digitized fields. The result is a
Byte value and the counter jumps from 255 to 0.
void Reset_CaptureCounter (WORD nDevNo)
Calling this routine sets the field counter back to zero.
