Get latest frame from camera using opencv

Question

I am using opencv 3.0 to capture frames from video camera. But processing the frame takes some time, so the next time I fetch a frame, it gives me an older frame. I want to capture always the last frame, how can I do this? capture.get(CV_CAP_PROP_POS_FRAMES) gives me error.

请尝试在同一函数中两次调用“捕获>> MatImage”或“ capture.read（MatImage）”语句。
