IDVDNavigatorSink
This interface is a COM connection point that allows applications to monitor the dynamic state of DVD playback. As the DVD-Video API encounters navigation-based events, it issues callbacks through the IDVDNavigatorSink interface. You must implement the specific IDVDNavigatorSink methods within your DVD player application.
The following table lists the methods for IDVDNavigatorSink in the order the compiler calls them.
| Programming element | Description |
|---|---|
| OnSPRMChange | Called whenever a system parameter (SPRM) value changes. |
| OnGPRMChange | Called whenever a general parameter (GPRM) value changes. |
| OnNewProgramChain | Called whenever the player switches to a new program chain (PGC). |
| OnNewProgram | Called whenever the player switches to a new program (PG). |
| OnNewCell | Called whenever the player switches to a new cell. |
| OnGOPUserData | Called when the player encounters user data in a group of pictures (GOP). |
| OnUOPChange | Called when the navigation manager receives a new user operation (UOP). |
| OnPlaybackStateChange | Called whenever the playback state changes. |
| OnDiskReadError | Called whenever the navigation manager is unable to read from the DVD volume. |
| ConfirmTemporaryParentalLevel | Called when the navigation manager receives a navigation command that changes the parental level (PTL_LVL). |
| OnNavigationException | Called when the navigation manager receives a navigation request that it cannot complete. |
The IDVDNavigatorSink interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
Remarks
You can obtain a pointer to an IDVDNavDataStatusSink interface by calling the IUnknown::QueryInterface method of a DVDData object and specifying the IID_IDVDNavDataStatusSink reference identifier.
