Transitions the filter to State_Running state if it is not already in this state.
HRESULT Run (REFERENCE_TIMEtStart);
Parameters
- tStart
Reference time value corresponding to stream time 0.
Return Values
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
DirectShow applications and DirectShow filters have different include file and link library requirements.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
