Releases any cached interfaces on the upstream pin.
Syntax
HRESULT ForceRefresh( ); |
Parameters
None.
Return Value
Returns S_OK.
Remarks
For efficiency, the CPosPassThruclass can cache the IMediaPositioninterface of the connected upstream output pin.
This method releases any cached interface pointers and forces them to be obtained again through QueryInterfaceif needed.
Presently, this class does not cache the upstream IMediaPositionso this member function is not necessary. It is left in for future flexibility.
