CBasePin::Active (Compact 2013)

  • Artigo

3/26/2014

Called by the CBaseFilter implementation when the state changes from stopped to paused or running.

Syntax

virtual HRESULT Active(void);

Parameters

None.

Return Value

Returns an HRESULT value.

The default implementation returns NOERROR.

Remarks

Any class that requires notification of a change of state should override this member function. This is called when the filter owning the pin exits the State_Stopped state.

The filter graph manager's internal state variable is not updated until after this member function returns, so avoid testing the filter graph manager's state (directly or indirectly) from within this member function.

Header

dshow.h,
