I think you are correct about the hardware decoding not working in FF or <br>
Chrome. I found a discussion about using a beta PPA of Chromium with <br>
VAAPI support turned on. I'm going to try that and see.<br>

I'll confirm the problem with top, but I think it's classic software <br>
decode vs. HW.<br>
