Thanks. That will give me something to look into over the weekend.

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?
Thanks

Yeah, I wouldn't use the proprietary AMD drivers. 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.
If you're wanting hardware video acceleration you can also install
the following packages:
mesa-va-drivers
vdpau-driver-all
Those are listed on this wiki page:

I also don't think I made it clear that mesa is probably better
than the proprietary AMD drivers on linux. The same is untrue on
NVIDIA.

Do you truly need proprietary drivers? That card is one of the
best supported by open source software. So I would just install
mesa, which should be easily installed from your distro's
package manager, if it's not installed already.
Assuming you do need proprietary, maybe try a reboot if you
haven't already? It's giving a missing binary error and
sometimes I get those after a kernel update and not rebooting.

Today the Radeon RX580 graphics card I bought arrived. To
get the drivers for the card, I went here
https://www.amd.com/en/support
<https://www.amd.com/en/support> where I downloaded
amdgpu-install_6.0.60002-1_all.deb
Next I started following the instructions at
https://amdgpu-install.readthedocs.io/en/latest/
<https://amdgpu-install.readthedocs.io/en/latest/> then I
started running into problems.
amdgpu-install --vulkan=amdvlk,pro gave me 2 errors:
E: Unable to locate package vulkan-amdgpu-pro and the same
for vulkan-amdgpu-pro:i386
I kept going and entered amdgpu-install -y
--usecase=workstation
That returned the errors Unable to locate package
amdgpu-pro and amdgpu-pro-lib32
With the error messages I figured I'd have problems, but I
tried to find out if I could use the hardware acceleration
so I entered|:|
|ffmpeg -i input.mp4 -c:v h264_amf -c:a copy output.mp4
That gave me several errors. The first one was [h264_amf @
0x562e1f855380] DLL libamfrt64.so.1 failed to open|
|So I tried sudo updatedb and locate libamfrt64.so.1 which
returned nothing. That told me the file wasn't there.|
|I tried to transcode a file with Handbrake but it didn't
show h264_amf among the available codec options.|
|I tried searching for how to install libamfrt64.so.1 but
all I got was references to steps I already tried.|
|Did I make a mistake somwhere or does AMD need to fix
something?|
|Thank for your help.|
