Installation
USE flags
Global
VAAPI support can be enabled system-wide by adding the vaapi value to the USE variable:
/etc/portage/make.confUSE="vaapi"
Enabling VAAPI support will pull in the x11-libs/libva package, which has the following USE flags:
These flags can be adjusted in /etc/portage/package.use.
The system needs to be updated if the USE variable has been set to vaapi:
root #emerge --ask --changed-use --deep @worldUsage
Run vainfo to check VAAPI support.
root #vainfovainfo: VA-API version: 0.35 (libva 1.3.1)
