BeginDrmSetupDecryptor provides a mechanism to dynamically create decryptors.

BeginDrmSetupDecryptor can be called any time after the MediaOpened state has been reached.

If the initial call to BeginDrmSetupDecryptor does not throw an exception, then there will be exactly one DrmSetupDecryptorCompleted event per call to BeginDrmSetupDecryptor.

A DrmSetupDecryptorCompleted event is raised when the operation is complete. If the AsyncCompletedEventArgs.Error property is null, then the setup was successful; otherwise, the setup failed and the AsyncCompletedEventArgs.Error property will contain an Exception object.
