Hi lilin

I suggest using DirectX with the SpoutDX class.
Look at the Tutorial04 example.

I downloaded your repository but CMake fails.

In Main.cpp you could try :

Line 8
#include “…..\SpoutDX\SpoutDX.h”
(depends where you put the SpoutDX files)

Line 27
spoutDX sender;

Line 69
if (!sender.OpenDirectX11(device))
return nullptr;
The function requires ID3D11Device* but you have used auto, so you might need to do something here.

Line 179
sender.SendBackBuffer();
This might work. Otherwise you have to get a texture as shown in Tutorial04.

Finally
Line 538
sender.ReleaseSender();
