    launch : function() {
        Ext.create('Ext.panel.Panel', {
            renderTo: Ext.getBody(),
            itemId: 'foo',
            html: '<iframe width="300" height="200" src="//content.jwplatform.com/videos/HkauGhRi-640.mp4" frameborder="0" allowfullscreen></iframe>',

For modern toolkit: https://docs.sencha.com/extjs/7.3.1/modern/Ext.Video.html

Ext.create({
    xtype: 'panel',
    renderTo: Ext.getBody(),
    width: 800,
    height: 600,
    shadow: true,
    scrollable: true,
    title: 'My Video Panel',
    layout: 'hbox',
    items: [{
        xtype: 'video',
        onVideoplayerid0Play: function (media, eOpts) {
            var video = Ext.get(media.id).select('video:first-of-type ', true).elements[0];
            if (video.style.display == 'none') {
                video.style.display = '';
            }
        },
        url: 'https://www.learningcontainer.com/wp-content/uploads/2020/05/sample-mp4-file.mp4',
        listeners: {
            painted: function (video) {
                video.play();
            },
            play: function(video) {
                // BUG fix. on auto play the black display is not disappeared. 
                document.getElementsByClassName('x-video-ghost')[0].style.display = 'none';
            }
        }
    }]
});
