Custom File Formats

If you have a custom mux or file-writer filter that supports your own file format, you can specify the CLSID as the first parameter of the SetOutputFileName method:

IBaseFilter *pMux = 0;
IFileSinkFilter *pSink = 0;
hr = pBuild->SetOutputFileName(&CLSID_MyCustomMuxFilter, 
    L"C:\\VidCap.avi", &pMux, &pSink);

For more information about this usage, see ICaptureGraphBuilder2::SetOutputFileName.
