lukpod [1] filed a deletion request for libva-xvba-driver [2]:
The last release of this was years ago.
This only works with Catalyst which hasn’t had a new release for over
6 months.
The latest release of Catalyst doesn’t work with xorg-server higher
than 1.17.
Catalyst has been superseded by other drivers (r600, radeonsi,
amdgpu).
The latest release of Catalyst has a new XvBA backend for VA-API which
supersedes this one.
Also delete xvba-sdk [1]; it’s only needed to compile this package;
there no other packages in the AUR which need xvba-sdk.
