Reading camera frames and video files

In some projects, you have to capture camera frames (for example, capture frames with the webcam of your laptop). In OpenCV, we have cv2.VideoCapture, which is a class for video capturing from different sources, such as image sequences, video files, and cameras. In this section, we are going to see some examples to introduce us to this class for capturing camera frames.

Reading camera frames

This first example, read_camera.py, shows you how to read frames from a camera that's connected to your computer. The required argument is index_camera, which indicates the index of the camera to read. If you have connected a webcam to your computer, it has an index of 0. Additionally, if you...
