We link to system's libva, so it should depend on version installed on
build machine. According to Phoronix article av1 encoder appeared since
libva 2.14 in early 2022.

I think for this one we need to update our ffnvcodec.tar.xz

https://github.com/FFmpeg/nv-codec-headers/commit/7947f29859f2fa7a9252309daeb4717030d027e0

I guess SDK 12.x is earliest with av1 ENCODE.

unfortunately,  this might mean I lose nvenc acceleration on legacy nvidia
proprietary 470 driver? We'll see.



I additionally have only av1_vaapi. @Terje, you also use a rolling,
