[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetFiltergraph method retrieves the IGraphBuilder interface for the filter graph used by the DVD-Video graph builder object.

Syntax

HRESULT GetFiltergraph(
  [out] IGraphBuilder **ppGB
);

Parameters

[out] ppGB

Address of a pointer to the IGraphBuilder interface that the DVD-Video graph builder object is using.

Return value

Returns an HRESULT value that depends on the implementation of the interface. The current DirectShow implementation returns E_INVALIDARG if ppGB is invalid.

Remarks

The returned IGraphBuilder interface pointer has an outstanding reference count. The caller must release the interface.
