IGraphConfig::RemoveFilterEx method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The RemoveFilterEx method removes a filter from the filter graph.
Syntax
HRESULT RemoveFilterEx(
[in] IBaseFilter *pFilter,
[in] DWORD Flags
);
Parameters
[in] pFilter
Pointer to the IBaseFilter interface of the filter to remove from the graph.
[in] Flags
Combination of flags from the REM_FILTER_FLAGS enumerated type.
Return value
Returns S_OK if successful, or an HRESULT value indicating the cause of the failure.
Remarks
This method extends the IFilterGraph::RemoveFilter method by accepting a flag that specifies the behavior of the method. This flag enables an application to remove a filter without disconnecting the pins automatically, which improves performance when moving groups of connected filters into a new graph.
By default, this method disconnects the filter before removing it from the graph. Use the REMFILTERF_LEAVECONNECTED flag to leave the filter connected.
