Hi,

Sorry for the out-of-the-blue outsider comment onto an old thread (hopefully the In-Reply-To header will work from the archive URL), but as various OSS multimedia projects would like these definitions to be in wine/mingw-w64, I can inform you that:

1. Since mid-May the structures have been officially defined in what was previously called MSDN: https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/dxva/ns-dxva-dxva_status_av1
2. MS seemingly today (?) released a stable SDK 10.0.20348.0 which finally is a non-insider SDK that defines these structures. It is not currently available in the VS installer, but it is available as a "server" SDK at https://developer.microsoft.com/en-US/windows/downloads/windows-10-sdk/ .

I hope this should enable these structures to be verified, and pulled in.

Best regards,
Jan
