Can i access QSV tech in Windows WSL？

ohye — Wed, 25 Sep 2019 21:56:21 GMT

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?
