python调用海康威视的摄像机

很简单的一个代码，但首先安装python环境。

然后安装，cv2,

pip install opencv-python

国内源

pip install -i https://mirrors.aliyun.com/pypi/simple/ opencv-python

 然后，就可以运行，

 
import cv2
url = "rtsp://admin:tjn12345@192.168.0.64/Streaming/Channels/0"
cap = cv2.VideoCapture(url)
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()
