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

Syntax

HRESULT RemoveChain(
  [in] IBaseFilter *pStartFilter,
  [in] IBaseFilter *pEndFilter
);

Parameters

[in] pStartFilter

A pointer to the IBaseFilter interface of the filter at the start of the chain.

[in] pEndFilter

A pointer to the IBaseFilter interface of 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 value

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.
