python opencv 读取rtsp视频流

import cv2 
cap = cv2.VideoCapture("rtsp://admin:[email protected]:554//Streaming/Channels/1")
ret,frame = cap.read()
while ret:
    ret,frame = cap.read()
    cv2.imshow("frame",frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
cv2.destroyAllWindows()
cap.release()

这就是最简单的方法，vlc是可视化界面由于不会操作故不太推荐大家使用
