IXMLGraphBuilder::SaveToXML method (amxmlgraphbuilder.h)

  • Articolo

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SaveToXML method saves a filter graph to an XML element.

Note  Support for this interface was removed in Windows 7. New applications should not use this interface.
