DxgiOuputDuplication texture frames to DirectX VideoProcessor - c++

Question

I was playing with this project DirectXVideoScreen because I am trying to find a way to convert RGBA to NV12 so I can make a video using the h264 transformation of my GPU. (You can only use the transformation when you have NV12 or YUV2 color format)
I have tried doing the color conversion using the Windows Media Foundation MFT (Video processor) but I am trying to go directly and use DirectX in order to have more control.
While you duplicate the screen the texture you get back is of type DXGI_FORMAT_B8G8R8A8_UNORM and I have to transform it to DXGI_FORMAT_NV12.
So I took the code from the project "D3D11VideoProcessor" and added the code from the "SimpleDesktopDuplication" project.
It is like this.
CD3D11VideoProcessor cD3D11VideoProcessor;
CSimpleDesktopDuplication cSimpleDesktopDuplication;
ID3D11Texture2D* output = NULL;
if (cSimpleDesktopDuplication.InitDesktopDuplication() == S_OK)
{
output = cSimpleDesktopDuplication.ProcessDesktopDuplication();
}
if(cD3D11VideoProcessor.InitDXVA2(2560,1440, DXGI_FORMAT_NV12) == S_OK)
{
cD3D11VideoProcessor.ProcessImageConversion(output, CONVERTED_IMAGE);
}
The problem (I think?) is that
m_pDXGIOutputDuplication->AcquireNextFrame(500, &FrameInfo, &pDXGIResource));
pDXGIResource->QueryInterface(__uuidof(ID3D11Texture2D), reinterpret_cast<void **>(&pScreenShotTexture2D)));
Returns a texture with the following flags.
Width: a00
Height: 5a0
MipLevels: 1
ArraySize: 1
Format: 57
Usage: 0
BindFlags: 28 // D3D11_BIND_RENDER_TARGET | D3D11_BIND_SHADER_RESOURCE
CPUAccessFlags: 0
MiscFlags: 2900
And here the code fails while executing

}
The error code is 0x80070057 meaning E_INVALIDARG One or more arguments are invalid.. I can not find the invalid arg :/
Can you help me ? or guide me ? Maybe I have to somehow change the ID3D11Texture2D* outputDuplicationTexture to match a simpler version of the texture (change misc params) ?
Thank you!
