issue with movie.py with renaming script

问题

I have a lot of videos stored in different subfolders. All the videos have weird file names like f4vd5sd1b5dsd41s415d. And I have a text file where there are the correct file names of each file. To know which video goes with which title, I added the file duration of the video I want to correspond with the title, so in my text file there is:

in line 1: the name of video 1

in line 2: the video length of video 1

in line 3: the name of video 2

in line 4: the video length of video 2

To better explain it here's some work I did manually:

Before:

After:

My script is:

import os
import shutil
from moviepy.editor import VideoFileClip

# parses the renaming rules described in your text file
# returns a dictionary where:
#    key represents the duration to match
#    value represents the name to rename the video file to
def parse_rules(path):
  with open(path) as file:
    lines = file.readlines()
    rules = { lines[i+1]: lines[i] for i in range(0, len(lines), 2)}
  return rules # structure { duration: rename_to, ... }

# gets the duration of the video file
def duration(file):
  return VideoFileClip(file).duration

 # determines whether the durations are close enough to   be considered similar
def is_close_enough(duration1, duration2):
  return duration1 == duration2

# makes a copy of source file according to the renaming rules specified and puts the resulting file in the destination folder 
def rename_by_rules(src_file, dst_dir, rules):
  for k, rename_to in rules.items():
    if is_close_enough(k, duration(src_file)):
      shutil.copy2(src_file, os.path.join(dst_dir, rename_to)) 

# begins renaming your video files matched by duration according to the rules in your text file
rules = parse_rules('<replace with your text file>')
for base, dirs, files in os.walk('<replace with your source director>'):
  for file in files:
    if file.endswith('mp4'):
      rename_by_rules(os.path.join(base, file), '<replace   by dest dir>', rules)

My Python version is 3.6.1 and I have Windows 7 64bit. The traceback call is:

"F:\Dossier Gros Nain\Python\Python 3.6.1\python.exe" "F:/Dossier Gros Nain/Pluralsight courses/1h Fundamentals of Arnold for Maya/Videos dupli - Copie/supreme script of death.py"

    if _WaitForSingleObject(self._handle, 0) == _WAIT_OBJECT_0:
OSError: [WinError 6] Descripteur non valide

Process finished with exit code 1

Is it a problem with movie.py? If yes, how could I remove it? Could I use ffprobe if nothing else works?
