Topic on Extension talk:Html5mediator

I made an update for this extension. I did not touch the original functioning of the extension.

You can now add the 3 additional parameters webm, mp4 and ogv in the <html5media> tag.

When you add minimum one of the 3 parameters, the extension will work in alternatives mode. In this case you must not give the file extension of the videa file.

Example: <html5media mp4 webm>File:SampleVideo</html5media> For this example you have to upload the two files SampleVideo.mp4 and SampleVideo.webm. If someone will access this page with Opera SampleVideo.webm will be shown, with Firefox SampleVideo.mp4 will be shown.

To install the update just replace the file /etensions/Html5mediator/Html5mediator.php with the following source code:

<?php

if ( !defined( 'MEDIAWIKI' ) ) die();

$wgExtensionCredits['html5mediator'][] = array(
	'path' => __FILE__,
	'name' => 'Html5mediator',

}

This works for me, but I had to switch the "$data = $image->getFullURL();" lines to "$data = $image->getCanonicalURL();" as I use a protocol-independant $wgServer setting, so there was no http: or https: at the front of the File names resulting in an error 20. Not sure if there's a better way to do it.
