Media aggregator services like embed.ly provide oEmbed support for a broad range of media services. embed.ly is a commercial media aggregator service that provides oEmbed support for over 250 different services. A complete listing of supported service providers can be found on embed.ly's site.
It's recommended that media aggregators be provided as a "fallback" service, used to attempt to match URLs for assets that don't match with any other services. A fallback can be specified by using a scheme using the * wildcard to match all URLs.
As a scheme of "*" will match all URLs it should be specified at the end of the list of services as services are tried in order until a match is found and "*" will match all URLs. Also, it is only valid to have a single endpoint associated with the "*" scheme.
The following example would ask youtube.com for how to insert YouTube videos, and embed.ly for all other links.
