[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetFiltergraph method specifies a filter graph for the capture graph builder to use.

Syntax

HRESULT SetFiltergraph(
  [in] IGraphBuilder *pfg
);

Parameters

[in] pfg

Pointer to the filter graph's IGraphBuilder interface.

Return value

Returns an HRESULT value. Possible values include the following.

Return code	Description
S_OK	Success.
E_POINTER	NULL pointer argument.
E_UNEXPECTED	Unexpected error.

Remarks

If you do not call this method, the capture graph builder automatically creates a filter graph when it needs one. If the capture graph builder already has a filter graph, this method returns E_UNEXPECTED.
