ruby on rails - how to get song cover art using TagLib -

here's code able song's picture/cover art.

taglib::mpeg::file.open("song_file_name.mp3") |file|     tag = file.id3v2_tag      cover = tag.frame_list('apic').first     mime_type = cover.mime_type     picture = cover.picture end 

how can convert value of picture url or image's source?

you should store content of picture in file, save it, , make available on web server.

try like:

taglib::mpeg::file.open("song_file_name.mp3") |file|     tag = file.id3v2_tag      cover = tag.frame_list('apic').first     mime_type = cover.mime_type     picture = cover.picture      extension = case cover.mime_type       when 'image/jpeg', 'image/jpg'         'jpg'       when 'image/gif'         'gif'       else         raise "mime not found"     end      file_name = "my_file.#{extension}"      file.open(file_name, "w") |f|       f.write(picture)     end  end
