INSTRUCTIONS:

modify the kaltura-embed.php file before installing to webdir/wordpress/wp-content/plugins folder

You will need to add your own mediaspace URL here which may only require you to change the yoursitehere portion if you have a hosted instance.

wp_oembed_add_provider( 'https://yoursitehere.mediaspace.kaltura.com/id/*', 'http://yoursitehere.mediaspace.kaltura.com/oembed/', false );
