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

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
