Comment (by eero-t):
I just noticed that in the vaapi backend iHD driver case, instead of
hwdownloading nv12 format, one could also remove the scale_vaapi stuff and
it works.
I.e. either format conversion, or scaling, but not both, are supported by
FFmpeg with iHD vaapi driver, although doing both works with i965 vaapi
driver (and when using iHD driver with MediaSDK sample_decode
application).
Removing scale_qsv doesn't help with FFmpeg QSV backend though, only nv12
hwdownload works with that.
