Comment (by eero-t):

 Verified, I don't anymore get the same error and everything works now
 using QSV & VA-API backends with '''iHD''' driver on GEN9+ '''Core'''
 devices.

 On BXT / APL devices I get now following error:

 And following with the '''i965''' VA driver on all other devices:
 {{{

 compatible with selected options (supported modes: CQP).
 }}}

 Should I file separate ticket(s) for these?  (Where?)
