IFilterChain::RemoveChain

The RemoveChain method removes every filter in a filter chain from the filter graph.

Syntax

  HRESULT RemoveChain(
  IBaseFilter *pStartFilter,
  IBaseFilter *pEndFilter
);

Parameters

pStartFilter

[in] Pointer to the filter at the start of the chain.

pEndFilter

[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.

Return Values

Returns S_OK if successful, or an HRESULT value indicating the cause of the failure otherwise.

Remarks

You can call this method while the graph is running; the method stops the filters in the chain before removing them from the graph.
