Python实现音频提取的示例详解

pip install moviepy

import moviepy.editor as mp
my_clip = mp.VideoFileClip("C:\\Users\\ME08I\\Desktop\\1.mp4")#ci此处为视频的绝对路径。
my_clip.audio.write_audiofile('./test.mp3')#此处为输出的音频名称和格式

import os
import moviepy.editor as mp
import tkinter as tk
from tkinter import filedialog
#关闭黑窗口
root = tk.Tk()
root.withdraw()
