python使用moviepy包下的VideoFileClip时报错：OSError: [WinError 6] 句柄无效解决方法

在使用moviepy包下的VideoFileClip获取视频时长，在连续获取了若干个视频时长之后，突然报错：

Traceback (most recent call last):

    run()

左侧是错误写法，右侧加了两行问题解决了：

 

正确获取视频时长的代码：

def get_video_time(video_path):
    """
    pip install moviepy
    获取视频时长（s:秒）,如果需要换算成时分秒，则调用time_convert()即可
    """
    from moviepy.editor import VideoFileClip
    video_clip = VideoFileClip(filename)
    durantion = video_clip.duration
    video_clip.reader.close()
    video_clip.audio.reader.close_proc()
    return durantion

因为感觉他写得太复杂，不太好看懂，自己简单的几行代码比较容易理解，就写了这么一篇水文
