METHODS

new

my $cs = new Audio::M4P::Decrypt;

my $cs_conparam = Audio::M4P::Decrypt->new(
strHome => ~, sPfix => ., dirSep => /
);

Optional arguments: strHome is the directory containing the keyfile directory. After running VLC on a .m4p file under Windows, MacOS X, and Linux, this should be found by the module automatically (APPDATA dir under Win32, ~/ under OS X and Linux). sPfix is . for MacOS/*nix, nil with Windows. dirSep is the char that separates directories, often /.

For debugging purposes, use eg: my $cs_conparam = Audio::M4P::Decrypt->new( DEBUG => 1, DEBUGDUMPFILE => m4ptree.html );

DEBUG turns on debugging output. DEBUGDUMPFILE is an output file name to dump an html picture of the m4p data structure.

DeDRMS

my $cs = new Audio::M4P::Decrypt;
$cs->DeDRMS(infilename, outfilename);

Decode infilename, write to outfilename. Reading slurps up an entire file, so output can overwrite the same file without a problem, we hope. Backup first.

DecryptFile

$cs->DecryptFile(infilename, outfilename);

More descriptive alias for the DeDRMS method.
