I'm trying to use the Video::Capture module (which has no docs) to capture
images from multple cards. I've finally found the following snippet of
code in the perl module itself:
sub new(;$) {
my $class = shift;
my $device = shift || "/dev/video0";
my $self = bless { device => $device }, $class;
It looks like the devie needs to be passed as the 2nd argument to the new
call., and if a 2nd arg is not received it defaults to the first card.
So far so good. Probel is the example cdoe I have passes _NO_ arguments to
the new call. Any idea what the first one should be?
