Video player

Starting from version 2.0.2 glightbox droped support of JWPlayer because that player implemented new restrictions for the free edition, it was replaced with an awesome new player "Plyr" that also includes support for youtube and vimeo. So instead of maintaining 3 different apis now we only can focus on one. You can pass any Plyr option to the player, view all available options here Plyr options.

Please note that GLightbox will only inject the video player library if required and only when the lightbox is opened.

const lightbox = GLightbox({
    plyr: {
        css: 'https://cdn.plyr.io/3.5.6/plyr.css', // Default not required to include
        js: 'https://cdn.plyr.io/3.5.6/plyr.js', // Default not required to include
        config: {
            muted: false,
            hideControls: true,
            youtube: {
                noCookie: true,
                rel: 0,
                showinfo: 0,
                iv_load_policy: 3
            },
            vimeo: {
                byline: false,
                portrait: false,
                title: false,
                speed: true,
                transparent: false
            }
        }
    }
});
