Plugin which allows you to apply extra control over the oembed functionality provided by the IPS core
allows group level control over which remote sites members of a group are allowed to embed.
allows group level control for automatically embedding internal IPS links.
provides you the ability to add other remote oembed sources which are not yet supported by IPS, such as http://developers.issuu.com/oembed/
Note: Plugin support does not include assisting you with researching whether a site supports oembed or not. Google, or the site itself, will be your friend in that situation
