Viewing mp4 files in Firefox

Question

I'm trying to embed an mp4 file in a video and object element, however it's failing to play/register - I wasn't able to find any sort of plugin so far. It would be great if someone could recommend some Firefox 3.5/Ubuntu Jaunty compatible plugin.

Answer 1

https://developer.mozilla.org/En/HTML/Element/Video says it only supports ogg theora so far. maybe an addon can do it, but i couldn't find any

Answer 2

Ended up using jwplayer, all you do is basically reference a swf and pass any media file and it'll play it.

<script src="swfobject.js"></script>
<script type="text/javascript">
    var s1 = new SWFObject("mediaplayer.swf","single","1280","544","7");
    s1.addParam("allowfullscreen","true");
    s1.addVariable("file","file.mp4");
    s1.addVariable("stretching","exactfit");
    s1.addVariable("smoothing","false");
    s1.addVariable("wmode", "direct");
    s1.write("player1");
</script>
