H.264 not available on a 3000 series card

[amq]

hi, thanks for your great project! I recently bought a new laptop with a 3070, but for some reason, H.264 doesn't show up in the Available Codec(s) list. What could theoretically cause this? I have the latest driver (471.11)

I've checked some items, but currently unabled to find out the cause.

I've tested 471.11 driver my self with RTX2070, but didn't have problem. Also, I got a --check-features result from a RTX3080 user which seemed to be fine (but with a old driver)), so it doesn't seem to be a RTX3xxx series problem.

Might be Windows version? Windows 10 21H2 should show Windows 10 x64 (19043), but you get Windows 10 x64 (22000).

Windows 10 x64 (22000).

That is Windows 11.
