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.
