Using Perl Mods to edit mp3 meta tags

ifeatu · 12-04-2009, 08:46 PM

Hello,

Im relatively new to Perl and I want to use Perl to write a simple script that takes a file name and chops it up and puts the contents into the meta tag of the file it came from (mp3).

eg

Filename: Jan_03_1991_The_Sufferings_of_Christ_BLH_Side_1.mp3

MetaTags:

Year: 1991
Album Name (In this order): 1991-01-03- The_Sufferings_of_Christ -BLH
Track Number: 1

So I installed the Perl mod from cpan for mp3::tag ID3 but have no idea how to begin to use it.

Can anyone help?

Yes, we can help. Post what you've written, and where you're getting stuck. You can also go out to CPAN and read the usage notes for the module, that explain how to use it.

You can also try perlmonks.com, for more perl-specific programming questions...they may already have code snippets out there too.

okay,

This is what I have done to learn how the module works, basically I just want to grab the metatag info that is already on the track and print it to the screen

This is what I have so far

Code:

 
  use MP3::Tag;
  
  $filename = d:\\Pierres_Tape_Library\\Labeled_Tracks\\April_20_1984_side_1.mp3;
  $mp3 = MP3::Tag->new($filename);

  $mp3->get_tags();
  $id3v2 = $mp3->{ID3v2} if exists $mp3->{ID3v2};

  print "The information in the metatag for the file is: $id3v2";

So I just get errors such as

Code:

Can't call method "get_tags" on an undefined value at mp3test.pl line 14

I DID install the module.

why don't you get this moved to the Programming section?
