我尝试在C++中使用DirectX 11来捕获屏幕并将其转换为我可以使用OpenGL或ImGui渲染的纹理。我使用了Windows API和BitBlt，但这导致fps低于15，所以这不是一个选项。
我使用的是Windows 11，带有Nvidia显卡。
库导入：

#pragma comment(lib, "dxgi.lib")
#pragma comment(lib, "d3d11.lib")

正在初始化DirectX 11：

bool DirectX11::initDirectX11() {
        HRESULT hr = S_OK;
        IDXGIFactory* DXGIFactory = nullptr;
        IDXGIAdapter* Adapter = nullptr;
        D3D_FEATURE_LEVEL FeatureLevel = D3D_FEATURE_LEVEL_11_0;
        Output = nullptr;
        deskDupl = nullptr;
        hr = CreateDXGIFactory(__uuidof(IDXGIFactory), (void**)(&DXGIFactory));
        if (FAILED(hr)) {
            std::cout << "Failed to create DXGI Factory" << std::endl;
            return false;
        }
        hr = DXGIFactory->EnumAdapters(0, &Adapter);
        if (FAILED(hr)) {
            std::cout << "Failed to create adapter" << std::endl;
            return false;
        }
        hr = Adapter->EnumOutputs(0, &Output);
        if (FAILED(hr)) {
            std::cout << "Failed to create output" << std::endl;
            return false;
        }
        hr = Output->QueryInterface(__uuidof(Output), (void**)(&deskDupl));
        if (FAILED(hr)) {
            std::cout << "Failed to create output1" << std::endl;
            return false;
        }
        hr = Output->GetDesc(&OutputDesc);
        if (FAILED(hr)) {
            std::cout << "Failed to get output description" << std::endl;
            return false;
        }
        hr = D3D11CreateDevice(Adapter, D3D_DRIVER_TYPE_UNKNOWN, NULL, 0, NULL, 0, D3D11_SDK_VERSION, &device, &FeatureLevel, &deviceContext);
        if (FAILED(hr)) {
            std::cout << "Failed to create D3D11 device" << std::endl;
            return false;
        }
        DXGIFactory->Release();
        Adapter->Release();
        return true;
    }

捕获屏幕：

void  DirectX11::captureScreen() {
        HRESULT hr = S_OK;
        IDXGIResource* DesktopResource;
        DXGI_OUTDUPL_FRAME_INFO FrameInfo;
        // Get new frame
        hr = deskDupl->AcquireNextFrame(500, &FrameInfo, &DesktopResource);
        if (FAILED(hr)) {
            std::cout << "Failed to acquire next frame" << std::endl;
            return;
        }
        
        // Store the frame as a texture
        // Trows exception
        // Read access violation
        // DesktopResource was 0xFFFFFFFFFFFFFFFF   
        hr = DesktopResource->QueryInterface(__uuidof(ID3D11Texture2D), reinterpret_cast<void**>(&AcquiredDesktopImage));
        if (FAILED(hr)) {
            std::cout << "Failed to query interface" << std::endl;
            return;
        }
    }

问题是它不断抛出读访问冲突异常。

Read access violation
DesktopResource was 0xFFFFFFFFFFFFFFFF
