/**
|
|
* This is a kind of example class how to do a oembed provider for a service, that doesn't support oembed.
|
|
* This provider reads the AudioBoo API to resolve Boos and produce embedded players.
|
|
* It is configurable, what type of player should be used.
|
|
*
|
|
* Converting is done in the getEmbed function. This is the main code.
|
|
* Everything else is only type converting that should be nearly the same in any custom provider
|
|
*
|
|
* All *.class.php files found in the customs directory will be included automatically
|
|
*
|
|
* After implementing the provider you have to add it to the providers.xml like this:
|
|
* <provider>
|
|
* <name>AudioBoo (3 different players)</name>
|
|
* <url>http://(audio)?boo.fm/boos/*</url>
|
|
* <class>AudioBooProvider</class>
|
|
* </provider>
