CBaseMediaFilter::Run (Windows Embedded CE 6.0)

1/6/2010

Transitions the filter to State_Running state if it is not already in this state.

Syntax

HRESULT Run (
  REFERENCE_TIME tStart
);

Parameters

  • tStart
    Reference time value corresponding to stream time 0.

Return Value

Returns an HRESULT value.

Remarks

If the filter is in State_Stopped state, the CBaseMediaFilter::Pause member function 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 CBasePin::Active member function, 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.

Filters should derive their filters from CBaseFilter and not from CBaseMediaFilter, so filters will not likely use this member function. Use CBaseFilter::Run instead.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
