AMF seems to require some additional (may be even closed-source/proprietary) components from amdgpu-pro ? 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. The opensource Mesa 23.3 seems to be an option in any case https://www.phoronix.com/news/Mesa-23.3-HQ-AV1-Radeon https://www.phoronix.com/review/arc-graphics-ubuntu-2310 The ArchLinux wiki "Hardware video acceleration" is a good overview for Linux options and driver installations for Intel, NVIDIA, AMD/ATI https://wiki.archlinux.org/title/Hardware_video_acceleration * Advanced Media Framework (AMF) is an open source framework which allows "Optimal" access to AMD GPUs for multimedia processing using the AMDGPU PRO Stack, Developed by AMD. * AMDGPU PRO proprietary driver is built on top of AMDGPU driver and supports both VA-API and VDPAU in addition to AMF. * NVAMDGPU PRO proprietary driver is built on top of AMDGPU driver and supports both VA-API and VDPAU in addition to AMF. DEC/NVENC - NVIDIA's proprietary APIs for hardware video acceleration, used by NVIDIA GPUs from Fermi onwards. The "av1_amf" encoder is included among the AV1 Encoders on my FFmpeg 6.0.1 currently on Tumbleweed-Slowroll. Also the FFmpeg "AV1 Video Encoding Guide" has a section "AMD AMF AV1" using the av1_amf encoder https://trac.ffmpeg.org/wiki/Encode/AV1#AMDAMFAV1
