Yes, amf is part of AMD's proprietary drivers, namely amdgpu-pro.
Other proprietary parts (OpenCL) have been put inside ROCm which is
open, but I don't think they will do that for amf.
Some time ago I had tried to create an x265-amf rendering profile, but
it didn't work. Now I don't have any amgpu-pro parts and can't try
anymore....

I expect you are right above, as I have no own experience yet with
the new AV1 encoding using GPU HWA.<br>
<br>
The opensource Mesa 23.3 seems to be an option in any case<br>

The ArchLinux wiki "Hardware video acceleration" is a good overview
for Linux options and driver installations for Intel, NVIDIA,
AMD/ATI <br>

The "av1_amf" encoder is included among the AV1 Encoders on my
FFmpeg 6.0.1 currently on Tumbleweed-Slowroll.<br>
<br>
Also the FFmpeg "AV1 Video Encoding Guide" has a section "AMD AMF
AV1" using the av1_amf encoder<br>
