          Derived classes should implement this function to fill a GUPnPDIDLLiteResource, representing the transcoded content, with parameters 
            specific to the transcoder, such as bitrate or resolution. The GUPnPDIDLLiteResource should be instantiated by calling this base class 
            implementation, passing the provided didl_item, item and manager parameters.
          Parameters:
          
            
              | didl_item | The DIDLLite item for which to create the resource, by calling the base class implementation. | 
            
              | item | The media item for which to create the DIDLiteResource, by calling the base class implementation. | 
            
              | manager | The transcoder manager to pass to the base class implemenetation. | 
          
          Returns:
