IDvdGraphBuilder::GetFiltergraph 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 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.
