ISourceControl

ISourceControl – it manages and creates sources of video and audio data by the next methods:

HRESULT getCollectionOfSources( BSTR* aPtrPtrXMLstring) - get collection of sources in XML form (SourceXMLDocument), where aPtrPtrXMLstring is a pointer on the create string;

HRESULT getSourceOutputMediaType( BSTR aSymbolicLink, DWORD aIndexStream, DWORD aIndexMediaType, IUnknown** aPtrPtrOutputMediaType) - get pointer on output media type of the source, where aSymbolicLink is a pointer on the unique symbolic link string of CaptureManager source, aIndexStream is index of stream in selected source, aIndexMediaType is index of media type in the selected stream in the selected source, aPtrPtrOutputMediaType is a pointer on the selected output media type of the selected source;

HRESULT createSourceNode( BSTR aSymbolicLink, DWORD aIndexStream, DWORD aIndexMediaType, IUnknown** aPtrPtrTopologyNode) - create source node from defined source settings, where aSymbolicLink is a pointer on the unique symbolic link string of CaptureManager source, aIndexStream is index of stream in selected source, aIndexMediaType is index of media type in the selected stream in the selected source, aPtrPtrTopologyNode is a pointer on the topology node which contains the selected source;
