In this post on OpenCV Python Tutorial For Beginners, I am going to show How to Read, Write, Show Videos from Camera in OpenCV.
We will see How to read video, display video and save video, How to capture from Camera and display it, we will see these functions : cv.VideoCapture(), cv.VideoWriter(). So we will Capture Video from Camera using opencv. So let us see How to process images of a video, frame by frame in video streaming using Opencv python.
The list of available codes can be found in fourcc.org – http://www.fourcc.org/codecs.php
Gist of code I used in this video (Display the webcam in Python using OpenCV (cv2))
Python: cv.CAP_PROP_FRAME_WIDTH: Width of the frames in the video stream.
Python: cv.CAP_PROP_FRAME_HEIGHT: Height of the frames in the video stream.
Color image loaded by OpenCV is in BGR mode. But Matplotlib displays in RGB mode.
