is Windows Graphics Capture API return such as DXGI_OUTDUPL_FRAME_INFO(LastPresentTime,LastMouseUpdateTime)

Question

hi,I'm used dxgi to capture the windows screen, but it draw cursor on the texture2d too slow with DrawIconEx.
and I find windows graphics capture can capture cursor,but there is some problem. it can't detect the image change or cursor change(such as LastPresentTime,LastMouseUpdateTime),so I can't filter the duplicate frames.Is there any other way?thanks

Hello @hao chen ,

Yes, you can detect mouse update and get update information via LastMouseUpdateTime.

For how does it work you can refer to this official sample: DXGIDesktopDuplication.

PtrInfo->LastTimeStamp = FrameInfo->LastMouseUpdateTime;  

Thank you!
