arbmind / desktop-duplication-cpp Goto Github PK

Hello arBmind,
I try to recreate the project that you did, with the only difference, that I want to send the buffer on the network.
I would like to know if it was possible to customize the output of the frame. For example, I have my desktop which is in 1920x1080, I would like to be able to receive the buffer and dirty rect in 1280x720.
I saw that there was the SetDisplaySurface function that could be applied before running DuplicateOutput.
Here is my code:

HRESULT hr;

 hr = gDevice->QueryInterface(IID_PPV_ARGS(&gDxgiDevice));
		if (FAILED(hr))
			return;
		hr = gDxgiDevice->GetParent(__uuidof(IDXGIAdapter), reinterpret_cast<void**>(&gDxgiAdapter));
		if (FAILED(hr))
			return;
		gDxgiDevice->Release();
		UINT Output = 0;
		IDXGIOutput *lDxgiOutput = nullptr;
		hr = gDxgiAdapter->EnumOutputs(Output, &lDxgiOutput);
		if (FAILED(hr))
			return;
		gDxgiAdapter->Release();
		hr = lDxgiOutput->GetDesc(&gOutputDesc);
		if (FAILED(hr))
			return;
		IDXGIOutput1 *lDxgiOutput1 = nullptr;
		hr = lDxgiOutput->QueryInterface(IID_PPV_ARGS(&lDxgiOutput1));
		if (FAILED(hr))
			return;
		lDxgiOutput->Release();
//Is it possible to customize the output here ? With SetDisplaySurface ?
		hr = lDxgiOutput1->DuplicateOutput(gDevice, &gDeskDupl);
		if (FAILED(hr))
			return;
		lDxgiOutput1->Release();
		gDeskDupl->GetDesc(&gOutputDuplDesc);

Is it possible for you to help me?
Thanks a lot

Hi @arBmind,

thanks a lot for this great tool. I am using it for sharing just a part of my screen in MS-Teams Meetings. To further customize the tool to my needs, I want to add a few changes. Unfortunately, I am not able to set up the Project in Visual Studio 2019 (Professional).

I have already installed the Windows 10 SDK and used the clang Toolset, but I receive the following Error-message:

'''
....\src\BaseRenderer.cpp(5,10): fatal error : 'PlainPixelShader.h' file not found
'''

Therefore, I suspect something is still wrong with my include directories. Since I am not very experienced with Direct-X development, I appreciate any tips. Thanks a lot for your help.

Great project,

I would like to capture windowed apps. All the sample I see talks about DXGI capturing the full desktop. So, is DXGI capable to do it? Any advice to do it?

I compiled this repository in Visual Studio Professional 2017.

The only difference being, I switched all paths in desktop-duplication.vcxproj from Community to Professional.
It compiles just fine. Running the program gives me the following black display.

Do you have an idea what can be causing this issue ?

Hello, I really like your work, you have done a great job. I have a question, is it possible to take a screenshot not of the whole desktop but just one application? Take a screenshot of the desktop and cut out the layers with unnecessary applications? I will be grateful for any answer.
