According to Phoronix article av1 encoder appeared since libva 2.14 in early 2022. https://www.phoronix.com/news/VA-API-libva-2.14-Released > I guess, as Andrew says, internal libva is out of date, or use the > system one directly. > Important missing, besides the Intel ones, is av1_nvenc.

We'll see.
