如何在 python 中使用 moviePy 通过多线程动态快进视频文件夹？

Question

I have a folder of videos which I want to fast forward using multiple threads using moviePy. How do I Fetch the videos from the folder dynamically instead of giving their paths statically? Here is my code:

1. from moviepy.editor import *

   import os

   from natsort import natsorted

   from threading import Thread

   def fast(path,thread_name):

    if os.path.splitext(path)[1] == '.mp4': #print(os.path.splitext(path)) clip = (VideoFileClip(path).fx(vfx.speedx, 5)) #print(clip) clip.to_videofile('G:/Ocsid Technologies/Video_1/'+thread_name + '.mp4', codec='libx264')

   t1 = Thread(target=fast, args=("G:/Ocsid Technologies/Video_1/sample1.mp4", 't1')).start()

t2 =Thread(target=fast, args=("G:/Ocsid Technologies/Video_1/sample2.mp4", 't2')).start()

t3 =Thread(target=fast, args=("G:/Ocsid Technologies/Video_1/sample3.mp4",'t3' )).start()

t4 =Thread(target=fast, args=("G:/Ocsid Technologies/Video_1/sample4.mp4",'t4' )).start()

You can enumerate files with glob.glob() and use enumerate to get a counter for your thread names.

import glob
# ...
for i, filename in enumerate(glob.glob("G:/Ocsid Technologies/Video_1/*.mp4"), 1):
    thread_name = f"t{i}"
    Thread(target=fast, args=(filename, thread_name)).start()
