Comment (by jkqxz):
Sounds like you have a complex case for which we don't know the device but
is working by internal automagic inside libmfx (assuming it actually did
use hardware before).
To explicitly make the device on Windows when multiple are present, you
want something like:
{{{
-init_hw_device dxva2=intel:N -init_hw_device qsv@intel
}}}
where N is the index of the Intel graphics adapter for D3D9.
Note that if you do not change any options then nothing has changed other
than the appearance of the warning. The warning is telling you that it
may not be working with hardware (though apparently it is anyway in your
setup by automagic inside the driver; it is just a warning after all) and
that if you do anything trickier then it probably won't work because we
don't know the device.
