dotnet-window-capture's Issues

DwmSharedSurface sample does not seem to be working with games, Edge, etc

I am using Windows 11 22H2 with NVidia graphics.

Trying to capture Edge, VS Code or video games (I tried on Dota 2) just returns blank texture.

I find it slightly weird as their windows have proper thumbnails in Win+Tab and the taskbar, which hints that DWM actually has their surfaces of some kind.

DwmSharedSurface Sample not Compiling

I have been trying to compile DwmSharedSurface Sample from the repo, but sharp dx is throwing exception like this:

SharpDX.SharpDXException: 'HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.'

I tried changing shader file location but it still throw exception here:

using var vertexShader = new VertexShader(device, vertexShaderByteCode);

Could you please resolve this issue

[DwmThumbnail] Export frame as image

Hey checked the code for DwmThumbnail, It seems like you directly push the frame to the WPF window.
Is there any way to export the frame to an image?

Thanks.

Replace with Vortice.Windows

SharpDX has no longer been maintained, replace implementations with Vortice.Windows.
