the base audio domain structure that describes each port.
The data structure is derived from base port class and contain audio domain specific parameters. Other elements can be added in the derived components structures.

the base contructor for the generic OpenMAX ST Audio port
This function is executed by the component that uses a port. The parameter contains the info about the component. It takes care of constructing the instance of the port and every object needed by the base port.
