Notifies the pin that the filter is flushing.
void Flushing( BOOL bInProgress );
Parameters
- bInProgress
- TRUE indicates flushing in progress; FALSE indicates not
flushing.
Return Values
No return value.
Remarks
If you are implementing your own filter, your pin must call this member function on BeginFlushand EndFlush( DeliverBeginFlushand DeliverEndFlushfor output pins) to say when it is flushing, as shown in the following example.
HRESULT CMyPin::BeginFlush() { Flushing(TRUE); //Or CBaseInputPin for input pins return CBaseOutputPin::BeginFlush(); } HRESULT CMyPin::EndFlush() { Flushing(FALSE); //Or CBaseInputPin for input pins return CBaseOutputPin::EndFlush(); }Note that capture filters that do not support seeking do not call this method.
