That could be a good idea but only based on a query interface, instead of MSDK 
initialization failure. 
There are many reasons may cause the failure but application can't what is the

I haven't see MFXVideoDECODE_Query() has exposed this, this could be addressed 
if you have a plan to improve MSDK query functions.
