Hi,
I've encountered a bug
as a user of Fedora, that's also mirrored by this Arch Linux
bug report. The vast majority of VA-API hardware video decoders
have disappeared for the RX 6700 XT GPU.
It seems this happened in the 5.13.x branch, and that it's still a problem in 5.14.x (at least Fedora's packaging of 5.14 RC4).
Please let me know if there's any more information I can provide, or if this was the wrong place to reach out.
Thanks,
Wyatt
