VideoCaptureGrab Method OpenCvSharp Class Library
Grabs the frame from camera or file. The grabbed frame is stored internally. The purpose of this function is to grab frame fast that is important for syncronization in case of reading from several cameras simultaneously. The grabbed frames are not exposed because they may be stored in compressed format (as defined by camera/driver). To retrieve the grabbed frame, cvRetrieveFrame should be used.
