Neat! AV1 encoding is painfully slow. I wonder what quality will you get when doing vulkan.
Just curious: which AV1 encoder were you using?
I ask because librav1e and libaom performance is dismal, but libsvtav1 can at least do ~1.00x speed, which is impressive considering how complex the codec is.
That’s not to say I don’t welcome improvements, though I think AV1 Vulkan requires hardware support I don’t have on my RX 580; it wasn’t until the RX 7000 series that AMD cards started getting hardware encoded support for AV1.
SVT-AV1 has also had some pretty major improvements in recent months and years. It's possible if tested even a year ago it will be significantly faster for the same quality today.
