I am getting ID3D10Device by hooking into DXGISwapChain::Present() method and then This->GetDevice(IID_ID3D10Device, &ppDevice);

The problem is that g_pIFR->NvIFRSetUpH264HWEncoder(&params); returns -4 or NVIFR_ERROR_DX_DRIVER_FAILURE. Why is that? This works fine with DirectX 9

int InitNVIFR(ID3D10Device *g_pD3DDevice)
{
    HINSTANCE g_hNvIFRDll=NULL;
    NvIFRLibrary NvIFRLib;
    //! Load the NvIFR.dll library
    if(NULL == (g_hNvIFRDll = NvIFRLib.load()))
        return -1;

    //! Create the NvIFRToH264HWEncoder object
    g_pIFR = (NvIFRToH264HWEncoder *) NvIFRLib.create (g_pD3DDevice, NVIFR_TOH264HWENCODER);
    if(NULL == g_pIFR)
    {
        gbx_error("Failed to create the NvIFRToH264HWEncoder\r\n");
        return -1;
    }

    for (DWORD i = 0; i < NUMFRAMESINFLIGHT; i++)
    {
        //! Create the events for allowing rendering to continue after a capture is complete
        g_aCanRenderEvents[i] = CreateEvent(NULL, TRUE, TRUE, NULL);    
    }
    g_hThreadQuitEvent = CreateEvent(NULL, TRUE, FALSE, NULL);

    //! Set up the H.264 encoder and target buffers
    DWORD dwBitRate720p = 3000000;
    double  dBitRate = double(dwBitRate720p);

    params.ppEncodeCompletionEvents = g_hCaptureCompleteEvent;
    params.dwTargetHeight = video_source_out_height(0);
    params.dwTargetWidth = video_source_out_width(0);

    NVIFRRESULT res = g_pIFR->NvIFRSetUpH264HWEncoder(&params);

    if (res != NVIFR_SUCCESS)
    {
        if (res == NVIFR_ERROR_INVALID_PARAM || res != NVIFR_ERROR_INVALID_PTR)
            gbx_error("NvIFR Buffer creation failed due to invalid params.\n");
        else
            gbx_error("Something is wrong with the driver, cannot initialize IFR buffers\n");
