使用ffmpeg.probe()获取视频元数据时遇FileNotFoundError求助

调用ffmpeg.probe()获取视频元数据时，触发了FileNotFoundError: [WinError 2] 系统找不到指定的文件错误，网上关于该问题的资料极少。先后尝试以下两种代码写法，均出现相同错误：

第一种写法：

import os
import ffmpeg

os.chdir('E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO')

pprint(ffmpeg.probe(filename='Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))

第二种写法：

pprint(ffmpeg.probe(filename='E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))

报错回溯信息如下：
