Ensures that a sample is waiting before allowing a pause.
virtual HRESULT CompleteStateChange( FILTER_STATE OldState );
Parameters
- OldState
- State prior to the transition.
Return Values
Returns S_OK if the filter can be paused; otherwise, returns S_FALSE.
Remarks
This member function is called from the CBaseRenderer::Pausemember function. If the filter is being paused and there is no sample waiting, the transition is not completed and the function returns S_FALSE until the first sample arrives. However, if the m_bAbortflag has been set, all samples are rejected so there is no point waiting for one. If a sample is available, this member function returns NOERROR.
