It is due to mfx.FrameInfo.Width/Height don't match coded_w/coded_h.
Reproduce: -hwaccel qsv -init_hw_device qsv -c:v vp8_qsv -i
/fate-suit/vp8-test-vectors-r1/vp80-00-comprehensive-001.ivf
-vf "hwdownload,format=nv12" -pix_fmt yuv420p -f md5 -
This patch also allows coded_w/h smaller than surface_w/h.
Sounds ok. The surface may be larger than the coded dimension (that
could be larger than the presentation dimension).
