Finally those frames should be displayed in a window sequentially. Here is the sample OpenCV. Load and Display Video OpenCV C++ cout read a frame from video stream" Display Image OpenCV C++. The slow, naive method to reading video frames with OpenCV . Lines display the frame to our screen and update our FPS counter.
