VA-API VP9 Encode For GStreamer??

[Patrick Cusack]

According this, https://en.wikipedia.org/wiki/VP9, Coffee Lake encodes VP9.

I rebooted and ran what you recommended:

rm ~/.cache/gstreamer-1.0/registry.*
export LIBVA_DRIVER_NAME=i965
gst-inspect-1.0 vaapi

That appears to work. I got this result. I’ll need to test it further. I didn’t see this prior.

[root at localhost ~]# gst-inspect-1.0 vaapi

Though as you can see, The VP9 encoder is gone in the iHD driver (the new driver). It is not clear why the default driver was flipped without checking if that would break existing userspace. So basically, if you want to see the VP9 encoder, for now you have to do:
