Identifies the reference clock to which the filter should synchronize activity.
HRESULT SetSyncSource( IReferenceClock * pClock );
Parameters
- pClock
- Pointer to the
IReferenceClockinterface.
Return Values
Returns an HRESULTvalue.
Remarks
This member function implements the IMediaFilter::SetSyncSourcemethod. It sets the m_pClockdata member to the pClockparameter and increments the reference count on the IReferenceClockinterface passed in.
This member function is most important to rendering filters and might not apply to other filters.
Filters should derive their filters from CBaseFilterand not from CBaseMediaFilter, so filters will not likely use this member function. Use CBaseFilter::SetSyncSourceinstead.
