oEmbed "Endpoint" URL to embed videos to WordPress

I’m looking for the proper “endpoint” URL for mediaspace’s oEmbed feature. I’m trying to get WordPress 3.5.1 to recognize MediaSpace’s oEmbed code so that it will embed video into posts and pages.

I found this old post that asks the same question, but it’s for KMS2: http://www.kaltura.org/what-kalturas-oembed-publisher-url. Our site is using KMS4 and the answer suggested in this old post does not work properly.

Here is the code I’ve currently got in the non-functional plugin, based on the wordpress codex (http://codex.wordpress.org/Function_Reference/wp_oembed_add_provider):

add_action( ‘init’, ‘kaltura_add_oembed_handlers’);

function kaltura_add_oembed_handlers(){
wp_oembed_add_provider( ‘#https?://media.up.edu/mediaspace/public/id/.*#i’, ‘http://media.up.edu/mediaspace/public/action/oembed/’, true );

Thanks for any help!

For anyone else looking for an answer tot his, a new knowledgebase article was posted here that answered my question: http://knowledge.kaltura.com/mediaspace-oembed-integration

@box Hi, just checked your question here. We currently got the same problem trying to add Kaltura oEmbed onto wordpress following this new Kaltura knowledgebase article. The Kaltura media content still didn’t recognized when add on wordpress post. Could you share what the Kaltura API oEmbed endpoint you pass to make it work? Thanks in advance!

function custom_oembed_provider() {
wp_oembed_add_provider( ‘https://video.vt.edu/id/*’, ‘https://video.vt.edu/oembed’, false );
add_action( ‘init’, ‘custom_oembed_provider’ );
