下面这段代码播放的视频没有声音，怎样才能连声音也一起播放呢？

Question

import cv2
import numpy as np
cap = cv2.VideoCapture('E:/电影/神偷奶爸2.rmvb')

# Check if camera opened successfully
if (cap.isOpened() == False):
    print("Error opening video stream or file")
# Read until video is completed
while (cap.isOpened()):
    # Capture frame-by-frame
    ret, frame = cap.read()
    if ret == True:
        # Display the resulting frame
        cv2.imshow('Frame', frame)

        # Press Q on keyboard to  exit
        if cv2.waitKey(25) & 0xFF == ord('q'):
            break

    # Break the loop
    else:
        break
# When everything done, release the video capture object
cap.release()

# Closes all the frames
cv2.destroyAllWindows()
