CWmaDecoderIntfc Class Reference

class CWmaDecoderIntfc : public CBase

Interface for sending configuration info to WMA 10 Pro decoder. This abstract class just provides the static NewL function for the creation of the proxy. Also, it defines the APIs to be implemented by the proxy and the real custom interface implementation.
