一、moviepy实现视频转音频
github地址：GitHub - Zulko/moviepy: Video editing with Python
二、示例代码

@File : 视频转音频.py
@Description :
1.方式1 https://github.com/Zulko/moviepy -> 推荐 510M转换耗时 112秒=2分钟 大小98M
MoviePy can read and write all the most common audio and video formats, including GIF, and runs on Windows/Mac/Linux, with Python 3.6+
pip install moviepy
2.方式2 特殊格式如m3u8 ffmpeg
