Decrease latency on camera view

Question

I read Ip camera but 500ms latency occurred on camera view. How can I decrease this value?

import cv2
cap = cv2.VideoCapture("rtsp:admin:admin@192.168.1.108/mpeg4 ")
while(True):
    ret, frame = cap.read()
    cv2.imshow("frame",frame)

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

       cap.release()
       cv2.destroyAllWindows()
