使用Java YouTube API仅检索YouTube视频的音频是否可能?
与如何在程序中提取YouTube视频的音频?非常相似。
那里的最佳答案是:
Writing an application for this might be overkill. Existing tools already do a pretty good job, and it's hard to beat their simplicity:
wget http://www.youtube.com/get_video.php?video_id=...
| ffmpeg -i - audio.mp3
All done!
If your application needs to do something special with the audio afterwards, it would make sense to write an app for that part. But for just getting the audio out, shelling out to ffmpeg will be a lot easier.
