Yes, it's using VA-API hardware acceleration. I would agree with you that this is unacceptable. What is the processor in your NAS? Most of the time they're underpowered and although you may be able to use VA-API, it's not cutting it. If new enough, you may be able to upgrade to QSV for better results, but it seems a bit off that your performance is so piss poor.
It's an Intel Celeron J4125. QSV wasn't much better, I switched to VA-API to test that one. Judging from this thread it should at the very least work at all. I don't care that much about performance, for that I have to buy something much better, but it just has to be better than what it is right now.
