MPlayerCapabilitiesObserver Class Reference

class MPlayerCapabilitiesObserver

This class is used to define the capabilities of the current application, and the implementation will generate AVRCP responses to the controller. For the event part of the API, it is recommended to add all events which make sense for the media player. In general, this will be everything except ESystemStatusChanged. The company ID part of the API is only needed if the media player needs to support vendor extensions other than bluetooth SIG. The bluetooth SIG company ID is always included in responses to a COMPANY_ID request.
