I've no idea what QuickSync is, but GPU assignment should would just fine.

And before that define <hostdev/> in the domain XML so that libvirt
enables the PCI assignment. For instance:

  00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530
(rev 06)

  <hostdev mode='subsystem' type='pci' managed='yes'>
      <address domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    <address type='pci' domain='0x0000' bus='0x00' slot='0x04'
