ColorSpaceConverter RenderlessMode   

hi @ all,

i will use ColorSpaceConverter in Renderless Mode but when i add the
Filter my Video play only one Frame.

Here is my Code:

HRESULT hr = NULL;

	IVMRMixerControl9			*m_pMixerControl = NULL;
	IBaseFilter					*m_pAviDecoder = NULL;
	IBaseFilter					*m_pColorSpaceCoverter = NULL;
	ICaptureGraphBuilder2		*m_pCaptureGraphBuilder2 = NULL;

	hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER,
IID_IGraphBuilder, (void**)&m_pGraphBuilder);

    if (SUCCEEDED(hr))
    {
		hr = CoCreateInstance(CLSID_VideoMixingRenderer9, NULL,
CLSCTX_INPROC_SERVER, IID_IBaseFilter, (void**)&m_pVMR9);
    }


	CoCreateInstance(CLSID_Colour, NULL, CLSCTX_INPROC_SERVER,
IID_IBaseFilter, (void **)&m_pColorSpaceCoverter);
	if(!m_pColorSpaceCoverter)
	{
		return 0;
	}

	if (SUCCEEDED(hr))
    {
		hr = m_pVMR9->QueryInterface(IID_IVMRFilterConfig9,
reinterpret_cast<void**>(&m_pFilterConfig));
    }

    if (SUCCEEDED(hr))
    {
		hr = m_pFilterConfig->SetRenderingMode( VMR9Mode_Renderless );
    }

	if (SUCCEEDED(hr))
    {
		hr = m_pFilterConfig->SetNumberOfStreams(2);

    }

    if (SUCCEEDED(hr))
    {
		hr = SetAllocatorPresenter(m_pVMR9);
    }

    if (SUCCEEDED(hr))
    {
        hr = m_pGraphBuilder->AddFilter(m_pVMR9, L"Video Mixing
Renderer 9");
    }

    if (SUCCEEDED(hr))
    {
		hr = m_pGraphBuilder-
>AddFilter(m_pColorSpaceCoverter,L"ColorSpaceConverter");
    }



	if (SUCCEEDED(hr))
    {
		hr = m_pGraphBuilder->QueryInterface(IID_IMediaControl,
reinterpret_cast<void**>(&m_pMediaControl));
    }

	if (SUCCEEDED(hr))
    {
		hr = m_pGraphBuilder->QueryInterface(IID_IMediaSeeking,
reinterpret_cast<void**>(&m_pMediaSeeking));
    }
	if (SUCCEEDED(hr))
    {
		hr = m_pVMR9->QueryInterface(IID_IVMRMixerControl9,
(void**)&m_pMixerControl);
	}
	m_pMixerControl->SetMixingPrefs(MixerPref9_RenderTargetYUV);

	if (SUCCEEDED(hr))
    {
		hr = m_pGraphBuilder->RenderFile(m_pFile, NULL );
    }

    if (SUCCEEDED(hr))
    {
		hr = m_pMediaControl->Run();
    }

    return hr;
