CMccInterface Class Reference

class CMccInterface : public CBase

MCC subsystem client interface. Class is used for setting up and controlling multimedia streams. Details of resources needed by the cleint are unknown, hence specified in details in every session.

MCC interface is based on four components: Session, link, stream and endpoint (sink or source). In order to create multimedia streams, client need to construct it by using these four components.
