Based on the DXVA AV1 specs https://www.microsoft.com/en-us/download/details.aspx?id=101577
The structures and the associated define are available in Windows SDK since at least 10.0.20231.0.
Is this something pre-released? Latest one I see is 10.0.19041.0, corresponding to Windows 10 2004. It does not have the types.
The GUIDs were present in previous SDKs as well.

Adding GUIDs is fine, since they are indeed present in current versions.

For that I think we should wait for released SDK.
