First off, I must say that I am not much of a video expert, I just know that hardware acceleration and encoding is supposed to help with putting load on the CPU and rendering video more efficiently to put it in very simplistic terms.

I have hardware acceleration successfully working using VAAPI on my setup but certain options dont work and they give the same error. QSV produces a similar error

If I check the box for "Hardware encoding" or "HEVC", they both generate the same error which is below. I have tried to set the permissions to /dev/dri to 755 and 777 based on some posts that I saw but that has not made any difference.

My questions are

1. Do I need these options?
2. If so what I can do to get it working?
