The player calls this function to create an instance of an interface into the library.

The player will use this instance to operate the IQCDMediaLibrary interface that it provides other modules. For a module to support this function call, the module must be able to instantiate any number of independent IQCDMediaLibrary instances. 

The player will pass this interface will be passed to other modules to allow them to access to some basic media library functionality. If the module does not support this type of access, it should not implement this function.
