import cv2
import numpy as np
import time

cap=cv2.VideoCapture('http://192.168.XX.XX:8080/video')
cap.set(3,320) #set heigt   >>refer propId
cap.set(4,240)  #set width
time.sleep(0.1)


while True:
  ret,frame = cap.read()
  cv2.imshow('frame',frame)

  if cv2.waitKey(1)&0xFF == ord('q'):
  break

cap.release()
cv2.destroyAllWindows()
