There's likely some setting you have to enable or change to enable hardware acceleration. You'll probably have to poke around or google for that as I'm not that familiar with those settings in Handbrake.
That said, depending on what you're trying to do, you may just want to use CPU encoding anyway. You have a lot more control over what the final product looks like with CPU encoding that you do hardware encoding. With hardware encoding you can give it some parameters but ultimately you get whatever the encoder spits out, while you have many more knobs to turn for CPU encoding. You'll spend more time encoding but you'll likely end up with a better quality and smaller file with CPU encoding.

> Thanks Ryan for the advice. You mentioned the mesa and vdpau drivers for hardware video acceleration. I'm testing handbrake now by having it transcode the same video (25 minutes) and same settings I mentioned earlier. ( H264 1440x1080 to 640x480). This time it's also using around 95% of the cpu and transcoding at around 80 fps. Is it using the hardware acceleration?

Jim, undo whatever it is that you did with the amdgpu-pro drivers and install the "xserver-xorg-video-amdgpu" (if you're on debian or a debian based distro, which I assume you are based on the mentioning of a deb package) and restart. That should be all you need.
