There is nothing new here. It's just using the best pick already in the 
D3D/DXVA to the decoder device, since it's going to replace the lavc va 

It's either forced by the user and used in automatic. In automatic we 
don't want to use D3D11 on Win7 even if it can kind of work (needs extra 
conversion as it can't display NV12). I am not aware of any other way to 
do this fine tuning. We can't dynamically change the priorities of modules.
