IMediaControl::AddSourceFilter

  • Article

This method 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.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
