访问视频流地址: http://172.20.11.42:8080/video

**Python代码：**

vim test.py

#coding=utf-8
    import cv2 
    import time
     
    if __name__ == '__main__':
     
        cv2.namedWindow("camera",1)
        #开启ip摄像头
        video="http://172.20.11.42:8080/video"   #此处@后的ipv4 地址需要修改为自己的地址
        capture =cv2.VideoCapture(video)
        num = 0;
        while True:
            success,img = capture.read()
            cv2.imshow("camera",img)
     
        #按键处理，注意，焦点应当在摄像头窗口，不是在终端命令行窗口
            key = cv2.waitKey(10) 
     
            if key == 27: 
            #esc键退出
                print("esc break...")
                break
            if key == ord(' '):
                 #保存一张图像
                num = num+1
                filename = "frames_%s.jpg" % num 
                cv2.imwrite(filename,img)
     
     
        capture.release()
        cv2.destroyWindow("camera")
