CBaseFilter::Run
Transitions the filter from paused to running state if it is not in this state already.
HRESULT Run (
REFERENCE_TIME tStart);
Parameters
- tStart
Reference time value corresponding to stream time 0.
Return Values
Returns an HRESULT value. The default implementation returns NOERROR.
Remarks
If the filter is in State_Stopped state, the CBaseFilter::Pause method is called first to transition the filter to State_Paused state, which has the effect of activating any of the filter's connected pins. If any pin returns a failure return code from its Active method, the function fails and the state is not changed. If this member function succeeds, the filter's m_State member variable is set to State_Running.
This member function holds the filter's lock.
