Can i access QSV tech in Windows WSL?

I built ffmpeg with libmfx in WSL(Windows Subsystem for Linux) but got "Error initializing the MFX video decoder: invalid handle" when I ran ffmpeg with "-hwaccel qsv".

 

I googled the error but got nothing helpful. I wanna know whether QSV is not supported in WSL?

In order for us to provide the most accurate response we just wanted to confirm a few details about your platform:

What is the model of the processor?

What is the model of the board?

If this is a laptop, what is the model of it?

Which is the Linux version that you are using?

I did some research to confirm what is QSV, but there are a lot of different concepts, could you please describe what do you mean by QSV?

Just to make sure, for what is the reason is that you need the information that you are requesting, are you working on a project or developing an application?
