Identifies the reference clock to which the filter should synchronize activity.
HRESULT SetSyncSource( IReferenceClock * pClock );
Parameters
- pClock
- [in] Pointer to the
IReferenceClockinterface.
Return Values
Returns an HRESULTvalue that depends on the implementation. HRESULTcan be one of the following standard constants, or other values not listed.
E_FAIL Failure. E_POINTER Null pointer argument. E_INVALIDARG Invalid argument. E_NOTIMPL Method isn't supported. S_OK or NOERROR Success. Remarks
This method is of most importance to rendering filters and might not apply to other filters. The pClockparameter can be NULL, meaning that the filter should run as fast as possible at its current quality settings without any attempt to synchronize. For example, a filter graph that is doing compression probably runs in this mode. Each filter takes as long as it needs.
