retrieve id3 informations from remote mp3 file

Question

I need to get these information not from a file located on my machine, but on another one.

In general I'm able to get these infos in this way:

TagLib::MPEG::File.open("myfile.mp3") do |file|

    tag = file.tag

    "Artist:     "      +   tag.artist      + " " +
    "Title:      "      +   tag.title       + " " +
    "Album:      "      +   tag.album       + " "

end

... but if I open a link to the file like "http:// .../myfile.mp3" It doesn't work. Why?

Is there a different way to resolve it?

Answer 1

TagLib only works on files on the local filesystem. To retrieve tags from remote files, you'd first have to download that file to your local disk.

Answer 2

So a path to the file system should be given to the TagLib::MPEG::File.open param, not a url.
