Changes the renderer to State_Paused if it isn't already.
HRESULT Pause(void);
Return Values
Returns an HRESULTvalue.
Remarks
The following steps comprise a pause operation.
- Commit the allocator used for the connection.
- Allow the thread for the upstream filter to wait in Receive.
- Cancel any outstanding clock advise links.
- Check to see if the renderer is connected and allow a state change.
- If a sample is available, complete the state change to State_Paused.
- If the member function succeeds, DirectShow sets the filter's
m_Statemember variable to State_Paused. If the renderer is
in the State_Stopped state, DirectShow calls the
CBasePin::Activemember
function for each of the renderer's connected pins.
This member function overrides CBaseFilter::Pause.
