我在Pycharm中运行 ffmpeg库 以下代码时出现错误

import ffmpeg
stream = ffmpeg.input('test.mp4')
stream = ffmpeg.hflip(stream)
stream = ffmpeg.output(stream, 'output.mp4')
ffmpeg.run(stream)

报错内容为

FileNotFoundError: [WinError 2] 系统找不到指定的文件。

以上报错主要可以看最后一句：FileNotFoundError: [WinError 2] 系统找不到指定的文件。

在模块安装正确的情况下，应该是电脑本地没有安装 ffmpeg软件 ，可以搜索 Windows下安装ffmpeg的教程，也可以直接参考以下链接：
