如何解决方法描述失败：453 带宽不足 - OpenCv python

我正在尝试使用 opencv python 打开两个 rtsp 流，当我只打开一个流时，我没有收到此错误，但是当我尝试打开两个或更多流时，会发生错误。我的服务器是 NVR。

import os
from imutils.video import VideoStream,FileVideoStream,FPS
import cv2
import numpy as np

data1= "20201229T171900z"
data2= "20201229T172200z"
rtsp1 = "rtsp://user:pass@192.168.0.4:554/streaming/tracks/101?"
rtsp1 = rtsp1 + "starttime="+data1+"&endtime="+data2

rtsp2 = "rtsp://user:pass@192.168.0.4:554/streaming/tracks/201?"
rtsp2 = rtsp2 + "starttime="+data1+"&endtime="+data2
    

vs1 = VideoStream(rtsp1).start()
vs2 = VideoStream(rtsp2).start()


while(True):
  frame1 = vs1.read()   
  frame2 = vs2.read()   


  frame1 = cv2.resize(frame1,(400,400))
  frame2 = cv2.resize(frame2,400))   
  esquerda = np.concatenate((frame1,frame2),axis=0)
    
  cv2.imshow('img',esquerda)
  key = cv2.waitKey(1)

  if key == ord("q"):
    break

vs1.stop()
vs2.stop()
