identifier 'D3D11AllocatorParams' in sample_multi_transcode app

When I build sample_multi_transcode app I get the following error ?

Any reason for this ?

Hi,

This is a known issue - some pieces of D3D11 code weren't put under defines for proper compilation with Windows SDK 7.0/7.1. You have two options to solve this:

1) install Windows SDK 8.0 and point the variable INTELMEDIASDK_WINSDK_PATH to that location

2)  Add #if MFX_D3D11_SUPPORT in the following pieces of code:

transcode_utils.cpp, line 764:

#if MFX_D3D11_SUPPORT

    D3D11AllocatorParams *d3d11AllocParams = dynamic_cast<D3D11AllocatorParams*>(pParams);

    if (d3d11AllocParams)   

        m_D3DAllocator.reset(new D3D11FrameAllocator);   

    else

#endif

        m_D3DAllocator.reset(new D3DFrameAllocator);

sample_multi_transcode.cpp, line 73:

    else if (m_bUseD3D11)

    {   

#if MFX_D3D11_SUPPORT

        m_pAllocParam.reset(new D3D11AllocatorParams); 

        m_hwdev.reset(new CD3D11Device());

        sts = m_hwdev->Init(NULL, 1, GetMSDKAdapterNumber() );

        MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, sts);

        sts = m_hwdev->GetHandle(MFX_HANDLE_D3D11_DEVICE, &hdl);

        MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, sts);

        // set Device to external dx11 allocator

        D3D11AllocatorParams *pD3D11Params = dynamic_cast<D3D11AllocatorParams*>(m_pAllocParam.get());

        pD3D11Params->pDevice =(ID3D11Device*)hdl;

#endif

    }

Regards,

Nina
