I'm using in JavaScript this lightbox:

https://getuikit.com/docs/lightbox.html

I'm calling on this form:

	var lightbox = UIkit.lightbox.create([
    {'source': url, 'autoplay':'true', 'type':'video'},
	
    
]);

lightbox.show();

});

Open in new window


The light box works but the video is not starting in autoplay. How can I start in autoplay?
And other questions is possible also to disable the video controls on the video after open in the autobox?

Thank you

The lightbox component does not appear to support autoplay

I modified the lightbox.js file to include this feature.
Line 447 of components/lightbox.js add this
var autoplay = data.item.autoplay ? 'autoplay' : '';

Open in new window

Line 449 change to
content: '<video class="uk-responsive-width" src="'+source+'" width="'+width+'" height="'+height+'" controls ' + autoplay + '></video>',

Open in new window
