MP3::Tag::ID3v1 is designed to be called from the MP3::Tag module. use MP3::Tag; $mp3 = MP3::Tag->new($filename); # read an existing tag $mp3->get_tags(); $id3v1 = $mp3->{ID3v1} if exists $mp3->{ID3v1}; # or create a new tag $id3v1 = $mp3->new_tag("ID3v1"); See MP3::Tag for information on the above used functions. * Reading the tag print " Title: " .$id3v1->title . " "; print " Artist: " .$id3v1->artist . " "; print " Album: " .$id3v1->album . " "; print "Comment: " .$id3v1->comment . " "; print " Year: " .$id3v1->year . " "; print " Genre: " .$id3v1->genre . " "; print " Track: " .$id3v1->track . " "; # or at once @tagdata = $mp3->all(); foreach $tag (@tagdata) { print $tag; } * Changing / Writing the tag $id3v1->comment("This is only a Test Tag"); $id3v1->title("testing"); $id3v1->artist("Artest"); $id3v1->album("Test it"); $id3v1->year("1965"); $id3v1->track("5"); $id3v1->genre("Blues"); # or at once $id3v1->all("song title","artist","album","1900","comment",10,"Ska"); $id3v1->write_tag(); * Removing the tag from the file $id3v1->remove_tag(); AUTHOR

title(), artist(), album(), year(), comment(), track(), genre() $artist = $id3v1->artist; $artist = $id3v1->artist($artist); $album = $id3v1->album; $album = $id3v1->album($album); $year = $id3v1->year; $year = $id3v1->year($year); $comment = $id3v1->comment; $comment = $id3v1->comment($comment); $track = $id3v1->track; $track = $id3v1->track($track); $genre = $id3v1->genre; $genre = $id3v1->genre($genre); Use these functions to retrieve the date of these fields, or to set the data. $genre can be a string with the name of the genre, or a number describing the genre. all() @tagdata = $id3v1->all; @tagdata = $id3v1->all($title, $artist, $album, $year, $comment, $track, $genre); Returns all information of the tag in a list. You can use this sub also to set the data of the complete tag. The order of the data is always title, artist, album, year, comment, track, and genre. genre has to be a string with the name of the genre, or a number identifying the genre. fits_tag() warn "data truncated" unless $id3v1->fits_tag($hash); Check whether the info in ID3v1 tag fits into the format of the file. as_bin() $str = $id3v1->as_bin(); Returns the ID3v1 tag as a string. write_tag() $id3v1->write_tag(); [old name: writeTag() . The old name is still available, but you should use the new name] Writes the ID3v1 tag to the file. remove_tag() $id3v1->remove_tag(); Removes the ID3v1 tag from the file. Returns negative on failure, FALSE if no tag was found. (Caveat: only one tag is removed; some - broken - files may have many chain-loaded one after another; you may need to call remove_tag() in a loop to handle such beasts.) [old name: removeTag() . The old name is still available, but you should use the new name] genres() @allgenres = $id3v1->genres; $genreName = $id3v1->genres($genreID); $genreID = $id3v1->genres($genreName); Returns a list of all genres, or the according name or id to a given id or name. new() $id3v1 = MP3::Tag::ID3v1->new($mp3fileobj[, $create]); Generally called from MP3::Tag, because a $mp3fileobj is needed. If $create is true, a new tag is created. Otherwise undef is returned, if now ID3v1 tag is found in the $mp3obj. Please use $mp3 = MP3::Tag->new($filename); $id3v1 = $mp3->new_tag("ID3v1"); # Empty new tag or $mp3 = MP3::Tag->new($filename); $mp3->get_tags(); $id3v1 = $mp3->{ID3v1}; # Existing tag (if present) instead of using this function directly SEE ALSO
