Below code cause both div show separately, panel is up, video is down.
but I want the video div inside the panel div, how to do this ?

var video = new Ext.BoxComponent({
el: 'video-div'
new Ext.Panel({
renderTo: 'panel',
width: 650,
height: 500,
<div id="panel"></div>
<div id="video-div" class="video-js-box" >
<video id="example_video_1" class="video-js" width="640" height="264" controls="controls" preload="auto" >
<source src="out.ogv" type='video/ogg; codecs="theora, vorbis"' />

BTW, Sencha has support for video type tag ? I know touch already has, how's the desktop ?

Thanks in advance.
