[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Note The ICaptureGraphBuilder interface is deprecated. Use ICaptureGraphBuilder2 instead.

Tells the graph builder object which filter graph to use.

Syntax

HRESULT SetFiltergraph(
  [in] IGraphBuilder *pfg
);

Parameters

[in] pfg

Pointer to an IGraphBuilder interface that specifies the filter graph to use for subsequent calls to the IFilterGraph::AddFilter method.

Return value

Returns an HRESULT value.

Remarks

The graph builder will automatically create a filter graph if you don't call this method. If you call this method after the graph builder has created its own filter graph, the call will fail.
