How to pause videos on a slide change?

It's possible only in the pro version as the "onSlideChange" event is not provided in the basic one. To pause YouTube videos, you have to append the "enablejsapi=1" parameter to the URL (for example, "https://www.youtube.com/watch?v=3nQNiWdeH2Q" into "https://www.youtube.com/watch?v=3nQNiWdeH2Q&enablejsapi=1"). The following example describes how to pause both HTML and YouTube videos (so you might want to modify it if you are using only HTML or only YouTube videos):

fsLightbox.props.onSlideChange = function (instance) {
var sources = instance.elements.sources;
for (var i = 0; i < sources.length; i++) {
var source = sources[i];
if (!source) {
if (source.tagName === "VIDEO") {
} else if (source.tagName === "IFRAME") {
