Do we need this anymore?

[jrummell, 2014/10/23 01:20:03]

Yes. MediaKeySession.generateRequest() needs it in step 6 ("If the CDM
corresponding to media keys's keySystem attribute does not support initDataType
..."). Maybe this will go away with the isTypeSupported changes?

 
     MediaKeySession* createSession(ScriptState*, const String& sessionType);
 
     ScriptPromise setServerCertificate(ScriptState*, DOMArrayBuffer* serverCertificate);
     ScriptPromise setServerCertificate(ScriptState*, DOMArrayBufferView* serverCertificate);
 
     static bool isTypeSupported(const String& keySystem, const String& contentType);

FIXME: Remove this.

[jrummell, 2014/10/23 01:20:03]

Done.
