int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    // Create a new Directshow graph
    IGraphBuilder *pGraph = NULL;
    CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC, IID_IGraphBuilder, (void **)&pGraph);

    // Add the FLV Directshow Source Filter to the graph
    IBaseFilter *pFilter = NULL;
    CoCreateInstance(CLSID_MainmediaFLVSourceFilter, NULL, CLSCTX_INPROC, IID_IBaseFilter, (void **)&pFilter);
    pGraph->AddFilter(pFilter, L"FLV Source Filter");

    // Configure the filter to play the FLV file
    IAMFilter *pIAMFilter = NULL;
    pFilter->QueryInterface(IID_IAMFilter, (void **)&pIAMFilter);
    pIAMFilter->put_VideoWindow(L"FLV File", L"C:\\path\\to\\file.flv");

    // Play the FLV file
    pGraph->Run();

    return 0;
}
