IMediaControl::AddSourceFilter
Adds to the graph the source filter that can read the given file name, and returns an IDispatch interface pointer representing the filter.
HRESULT AddSourceFilter(
BSTR strFilename,
IDispatch **ppUnk);
Parameters
- strFilename
[in] Name of the file containing the source video. - ppUnk
[out] Pointer to the interface on the filter.
Return Values
Returns an HRESULT value.
Remarks
This method is primarily for use by Automation clients because it returns an IDispatch interface pointer. C and C++ applications should call the IGraphBuilder::AddSourceFilter method to perform this operation for maximum efficiency.
