FileNotFoundError：[WinError 2] Mediainfo

Question

我试图找出文件是否是视频。目前正在尝试使用pymediainfo，但我仍然坚持这个错误：

Traceback (most recent call last):
  File "C:/Users/Ankka/Downloads/test.py", line 6, in <module>
    fileInfo = MediaInfo.parse(o)
  File "C:\Python34\lib\site-packages\pymediainfo\__init__.py", line 90, in parse
    p = Popen(command, stdout=fp_out, stderr=fp_err, env=environment)
  File "C:\Python34\lib\subprocess.py", line 859, in __init__
    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

我使用此代码收到此错误：

from pymediainfo import MediaInfo

o = "D:/Zeluge/video.mkv"

fileInfo = MediaInfo.parse(o)
for track in fileInfo.tracks:
   if track.track_type == "Video":
       print(o)
