x264 is a video encoder, Intel QuickSync (as available through libva)
is a different video encoder. x264 can't "use" libva in much the same
way that a Toyota can't "use" a Ford. If you're using libva, you're
not using x264, much like if you're driving a Ford, you're not driving
a Toyota.

QuickSync also isn't GPU-powered, it's a dedicated hardware encoder.
