Comment (by eero-t):

 VAAPI & QSV command lines work (at least with latest Git versions of
 everything), '''if''' one does scale_vaapi/scale_qsv=<size> in addition to
 format conversion.  Just doing format conversion fails (which is nearly
 reverse of issue #7691).

 Hoewever, even that fails, if input is 4K instead of FullHD (tested on
 KBL).
