The StopChain method switches all the filters in a filter chain into a stopped state.
HRESULT StopChain( IBaseFilter *pStartFilter, IBaseFilter *pEndFilter );
[in] Pointer to the filter at the start of the chain.
[in] Pointer to the filter at the end of the chain. If this parameter is NULL, the method uses the longest possible filter chain that extends downstream from the start filter.
Returns S_OK if successful, or an HRESULT value indicating the cause of the failure otherwise.
