SpoutReceiver not working: Failed to create 2D texture shader resource

[pholz]

In Unity 2023.1.0b20 I get the following warning:

d3d11: Creating a default shader resource view with dxgi-fmt=29 for a texture that uses dxgi-fmt=87

and error:

d3d11: failed to create 2D texture shader resource view id=1801 [D3D error was 80070057]

No matter what format I specify in the Unity render texture, it always creates a "dxgi-fmt" of 29 which is DXGI_FORMAT_R8G8B8A8_UNORM_SRGB according to this page. Ans this does not seem to match any output I can create in unity itself or any other program.

Same issue in Unity 2022.20b16.
