How to set video capture format in opencv using python?

Question

I have a webcam which supports YUYV (raw) and MJPEG (compressed) formats. When I capture video stream - cap = cv2.VideoCapture(0) , openCV takes YUYV as default.

I want to use MJPEG (MJPG). I found here that it is possible. I try to set it by command: cap.set(7, ('M', 'J', 'P', 'G')) , but it doesn't work. How can I choose which video format I want to get in OpenCV?

请尝试以下行。

cap.set(8, ('M', 'J', 'P', 'G'))
