  Maybe the following script could be of use also. Not sure 
  if it will work on a 2Gb file, but this could be a good 
  test ;)

#!/usr/bin/perl
use strict;
use warnings;

use Net::Pkt;

my $dump = Net::Packet::Dump->new(
   file            => $ARGV[0],
   filter          => $ARGV[1] ? $ARGV[0] : '',
   overwrite       => 1,
   unlinkOnDestroy => 0,
   noStore         => 1,
   callStart       => 1,
);

while (my $f = $dump->next) {
  if ($f->l7) {
      my $binData = $f->l7->data;
      print unpack('H*', $binData), "\n";
      # Do whatever you want with this $binData here
   }
}
