cv2播Video+声音 cv2+ffpyPlayer 【附码】

cv2 只有影像，没有声音。 只播影像简单方法如下：
上一篇 cv2影像播放方式
如果还要加上声音，就要借助 ffpyPlayer了，基本写法如下：

from ffpyplayer.player import MediaPlayer

filename = 'YourVideo.mp4'
player = MediaPlayer(filename)
val = ''
while val != 'eof':
     frame, val = player.get_frame()
     if val != 'eof' and frame is not None:
         img, t = frame

不过，要先安装 ffmpeg，安装设定方式，可参考官方说明。
现在，把两者加在一起，让cv2 播影片时有声音了。( 按Esc中断播放 )
