For video, you need to look at WebKit which has a working gstreamer built right in. Read the gstreamer faq

Webkit is the lib to use now for html access. It plays videos. It has a perl module too Gtk2::Webkit

Gstreamer has it's own perl module also, if you don't need to view the camera stream thru a web address.

Webkit takes awhile to build, and has a few required dependencies; but it plays youtube videos right inside a Gtk2 window. I tested it all yesterday, and it all works. (You may also be able to use mplayer, embedded into a Gtk2 window. Google for examples.

#!/usr/bin/perl

use strict;
use warnings;
use Gtk2 -init;
use Gtk2::WebKit;

my $view = Gtk2::WebKit::WebView->new;

my $sw = Gtk2::ScrolledWindow->new;
$sw->add($view);

my $win = Gtk2::Window->new;
$win->set_default_size(800, 600);
$win->signal_connect(destroy => sub { Gtk2->main_quit });
$win->add($sw);
$win->show_all;

$view->open( $ARGV[0] // 'http://www.perlmonks.org' );
Gtk2->main;
