Can this be used with a non-hosted (youtube or vimeo) videos?

Hi, as far as I know the plugin only works with external links from YouTube and Vimeo. You need to add a video ID number. Internal links don’t have a video ID number.

Hello;

Yes, that is what I figured. Can you suggest a similar plugin to do the same with self hosted videos?

Thanks,
Tamer
