如果是mp4要怎麼改

cap=cv2.VideoCapture(data['url'])
print(data['url'])
while True:
    ret,m=cap.read()
    if ret==False:
        break
    size=m.shape
    m=cv2.resize(m, (608, int(608/size[1]*size[0])))
    cv2.imshow(data['url'],m)
    if data['url'].find('.mp4')==-1 :
        cv2.waitKey(0)
    else:
        cv2.waitKey(32)       
cv2.destroyAllWindows()
