(Not surprisingly) You were probably right:
While I know of one file in the conformance suite, HCAFF1_HHI, that claims not
to decode correctly because of PAFF and spatial direct, but has all crc's
correct (and a second one, Sharp_MP_PAFF_1r2, that decodes much better than the
message would suggest), cabac_mot_picaff0_full shows the typical artifacts that
are reported so often, but does not contain spatial direct mode.
Should I remove the warning?
