Transitions the filter from paused to running state if it is not in this state already.

Syntax 

HRESULT Run (
  REFERENCE_TIME 
tStart
);

Parameters

tStart

Reference time value corresponding to stream time 0.

Return Value

Returns an HRESULTvalue. The default implementation returns NOERROR.

Remarks

If the filter is in State_Stopped state, the CBaseFilter::Pausemethod 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 Activemethod, the function fails and the state is not changed.

If this member function succeeds, the filter's m_Statemember variable is set to State_Running.

This member function holds the filter's lock.

Requirements
