• 将视频文件放在D盘，编写代码转换

from moviepy.editor import VideoFileClip
 
# 输入视频文件路径
video_file_path = 'D:\qqq.mp4'
 
# 输出音频文件路径
audio_file_path = 'D:\qqq.mp3'
 
# 加载视频文件
video = VideoFileClip(video_file_path)
 
# 提取音频并写入文件
video.audio.write_audiofile(audio_file_path)
 
print(f"音频文件已保存到 {audio_file_path}")

• cmd中执行py文件进行转换

(env_dev1) C:\Users\dogle>python C:\Users\dogle\Desktop\aa.py
