Handlers for onStart, onComplete etc

The FancyBox API lists a number of handlers to enable hooks for javascript functions.
I need to pause some background video when opening a fancybox, but the closest I can get is using an anchor trigger (which won’t restart the video after Fancybox closes, obviously).
Are these (or the v2 ones: beforeShow, afterShow, etc) handlers available? I can’t seem to get them to work…

$('a.fancybox-youtube').fancybox({
        onStart: function() {
            return window.confirm('Continue?');
        },
        onCancel: function() {
            alert('Canceled!');
        },
        onComplete: function() {
            alert('Completed!');
        },
        onCleanup: function() {
            return window.confirm('Close?');
        },
        onClosed: function() {
            alert('Closed!');
        }
    });
