Hello Steve,
These definitions don't seem to be present in my Windows 7 or 10 SDK. Do you have a Windows SDK in which they are present?
ἔρρωσο, Zebediah
The structures are not present in the current stable Windows 10 SDK 19041 build aka. 20H1. I have found those in the latest Windows 10 Insider SDK 20206 build aka. 20H2. Also the docx provided by Steve Lhomme has this in the copyright notice:
"Information and views expressed in this document, including URL and other Internet Web site references, may change without notice. You bear the risk of using it."
But the DXVA_ModeAV1_VLD GUIDs are present in 20H1 WinSDK which may be added safely.
