python - 在python中将视频转换为音频

问题描述

我尝试制作一个转换器应用程序，它可以从 youtube 下载 .3gpp 格式的视频并将其转换为 mp3，但我有一些关于权限的问题，我现在真的不关心 windows 和 python 权限。

import pytube
import moviepy.editor as mp

while True:
    url = input("Video url: ")
    print("Downloading video....")
    youtube = pytube.YouTube(url)
    video = youtube.streams.first()
    video.download(r'C:\Users\Silver\Downloads\video.3gpp')
    print("Converting video....") 
    clip = mp.VideoFileClip(r"C:\Users\Silver\Downloads\video.3gpp")
    clip.audio.write_audiofile(r"C:\Users\Silver\Desktop\INFO\PythonFiles\Python\Youtube MP3 Converter\mp3 conv")

错误：

Traceback (most recent call last):
  File "C:\Users\Silver\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\video\io\ffmpeg_reader.py", line 285, in ffmpeg_parse_infos
    line = [l for l in lines if keyword in l][index]
IndexError: list index out of range

During handling of the above exception, another exception occurred:
