<p>Thanks. I've read that tonight. Earlier just for the fun of it
I installed the Radeon drivers on winsows10. I installed
handbrake and had it transcode the same video I experimented with
earlier. When I chose the codec, I found H.264 (AMD_VCE). There
was also an H.265 AMD_VCE option but I didn't try it. Handbrake
in Windows was transcoding the video at around 100 to 110 fps and
only using 1% of the CPU. I may not use hardware acceleration for
encoding often, but I'd like to have it available. It doesn't
matter to me if I use the open source drivers or the proprietary
ones. I can't help but wonder why it won't work in Linux.<br>

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.</span> <br>

truly need proprietary drivers? That card is one of the best

mesa, which should be easily installed from your distro's

you do need proprietary, maybe try a reboot if you haven't

get those after a kernel update and not rebooting.</span> <br>

<p>amdgpu-install --vulkan=amdvlk,pro gave me 2 errors:</p>
<p>E: Unable to locate package vulkan-amdgpu-pro and the
same for vulkan-amdgpu-pro:i386</p>
<p>I kept going and entered amdgpu-install -y
--usecase=workstation</p>
<p>That returned the errors Unable to locate package
amdgpu-pro and amdgpu-pro-lib32</p>
<p>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<code>:</code></p>
<p><code><font face="Helvetica, Arial, sans-serif">ffmpeg
-i input.mp4 -c:v h264_amf -c:a copy output.mp4<br>
<br>
That gave me several errors. The first one was
[h264_amf @ 0x562e1f855380] DLL libamfrt64.so.1
failed to open</font></code></p>
<p><code><font face="Helvetica, Arial, sans-serif">So I
tried sudo updatedb and locate libamfrt64.so.1 which
returned nothing. That told me the file wasn't
there.</font></code></p>
<p><code><font face="Helvetica, Arial, sans-serif">I tried
to transcode a file with Handbrake but it didn't
show h264_amf among the available codec options.</font></code></p>
<p><code><font face="Helvetica, Arial, sans-serif">I tried
searching for how to install libamfrt64.so.1 but all
I got was references to steps I already tried.<br>

<p><code><font face="Helvetica, Arial, sans-serif">Did I
make a mistake somwhere or does AMD need to fix
something?</font></code></p>
