CBaseMediaFilter::GetSyncSource

  • Article

Retrieves the current reference clock in use by this filter.

HRESULT GetSyncSource(
IReferenceClock** pClock
);

Parameters

  • pClock
    Pointer to a reference clock; will be set to the IReferenceClock interface.

Return Values

Returns an HRESULT value

Remarks

This member function implements the IMediaFilter::GetSyncSource method. It returns the value of m_pClock after adding a reference to it. Be sure to release the interface by calling the IUnknown::Release method when finished with the pointer.

Filters should derive their filters from CBaseFilter and not from CBaseMediaFilter, so filters will not likely use this member function. Use CBaseFilter::GetSyncSource instead.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
