Question

I m using MediaElement.js as my HTML5 video player for a site in progress. It works fine in Chrome, Safari, and Firefox, even with the fallback player, but in Internet Explorer I get the Javascript error seen here: http://d.pr/Jsfo. It doesn t seem to be loading my poster, or my player style (which works fine in the other browsers).

The player s code is being loaded dynamically, because it appears in a lightbox and there are multiple videos that can be played on the page. The Javascript that injects the HTML is at the bottom of the page

Unfortunately, you can t dynamically insert HTML5 tags in IE because it breaks their nesting

<video>
   <source src="file.mp4">
   <source src="file.webm">
</video>

becomes

<video />
<source src="file.mp4">
<source src="file.webm">

And then MediaElement.js can t figure out where the source files are.

My recommendation would be to put a <video> tag in a permanent spot on the page, then prepare a MediaElement object

var player = new MediaElementPlayer( #video );

and then when you re ready to play a video, just call it

// single MP4
player.setSrc( newfile.mp4 );

// OR multiple
player.setSrc([{src: newfile.mp4 ,type: video/mp3 },{src: newfile.webm ,type: video/webm }]);

// load and play
player.load();
player.play();

Also, you should remove the <object> embed HTML inside the <video> tag since that s only for cases when IE users don t have JavaScript enabled, and your app requires JavaScript.
