python3 使用Opencv打开USB摄像头,配置1080P分辨率的操作

我就废话不多说了，直接上代码吧！

import cv2
import time

cap = cv2.VideoCapture(0)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)

cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter.fourcc('M', 'J', 'P', 'G'))

while True:
    ret, frame = cap.read()

    cv2.imshow("test", frame)

    print(time.time())
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()
