如何在 openCV 中同时播放带有音频的视频

问题描述

我正在尝试使用 openCV 播放视频，但它只显示没有声音的视频，请您帮我解决这个问题，这是我的代码。

( 我有一个 macOS Mojave 版本 10.14.6 )

import cv2

from ffpyplayer.player import MediaPlayer


video = cv2.VideoCapture('videos/nature.mp4')
player = MediaPlayer('videos/nature.mp4')

while True:
    # read video frame by frame
    isTrue,frame = video.read()
    audio_frame,val = player.get_frame()
    cv2.imshow('Video',frame)
    
    if val != 'eof' and audio_frame is not None:
        #audio
        img,t = audio_frame
    
    if cv2.waitKey(28) & 0xFF == ord('q'):
        break
    
video.release()
cv2.destroyAllWindows()

我尝试使用 ffpyplayer，但在我的 ma​​cOS 上出现此错误。
