python实现rtsp取流并截图

import cv2
def get_img_from_camera_net(folder_path):
	cap = cv2.VideoCapture("rtsp://admin:admin@10.82.21.151/ch1/stream1")#获取网络摄像机
   
	i = 1
	while i<3:
		ret, frame = cap.read()
		cv2.imshow("capture", frame)
		print (str(i))
		cv2.imwrite(folder_path + str(i) + '.jpg', frame)# 存储为图像
		if cv2.waitKey(1) & 0xFF == ord('q'):
			break
		i += 1
	cap.release()
	cv2.destroyAllWindows()

# 测试
if __name__ == '__main__':
	folder_path = 'D:\Anacon'
	get_img_from_camera_net(folder_path)
