IDvdControl2 Interface

The IDvdControl2 interface navigates and plays DVD-Video titles. The DirectShow DVD Navigator source filter implements this interface. After creating a DVD filter graph through the IDvdGraphBuilder interface, a DVD player application uses the methods of the IDvdControl2 and IDvdInfo2 interfaces to send DVD commands to and retrieve state information from the DVD Navigator.

IDvdControl2 provides the full functionality required by the DVD Annex J specification, as well as methods for playback, menu navigation, and parental control. For more information on writing a DVD player application using the DVD Navigator, including topics on the DVD filter graph, command synchronization, parental controls, menus, and karaoke support, see DVD Applications.

In addition to the methods inherited from IUnknown, the IDvdControl2 interface exposes the following methods. The methods are grouped by functional area.
