读取ID3标签而不下载整个文件 [英] Read ID3 tags without downloading the whole file

问题描述

是否可以读取MP3文件的ID3标签(持续时间，艺术家，标题...)，而不必下载整个文件?

Is it possible to read ID3 tags (Duration, Artist, title...) of an MP3 file without having to download the whole file?

我做了一些测试，仅下载了几个字节的MP3文件，就能够获得Artist和title标签..但是我不确定Duration和其他标签是否可能.

I did a few tests and I was able to get the Artist and title tags with only downloading a few bytes of the MP3 file.. but I'm not sure if it's possible for Duration and other tags..

谢谢.

推荐答案

我只是发现ffmpeg可以读取远程文件的ID3标签，而不必下载整个文件:

I just find out that ffmpeg can read ID3 tags of a remote file without having to download the whole file:
