• FFMPEG AMF Hardware Acceleration on AMD Ryzen™ 7 7700 Server in Ubuntu 22.04 [closed]

  4 décembre 2024, par LoNormaly

  I was trying to make ffmpeg available with AMF and have access to the AMF hardware acceleration (in ffmpeg -hwaccels) but failed.

  


  At first, the kernel that the server as Ubuntu 22.04 came with was 5.15 and after contacting support I was explained that I need to upgrade the kernel to have access to /dev/dri.

  


  So I upgraded to 6.8 and then I had access to /dev/dri and was able to use ffmpeg 7.1 with vaapi working.

  


  In AMD, they have their own hardware acceleration named AMF, that allows much better speed and quality of transcoding.

  


  I installed the AMD GPU drivers like it's explained here : https://www.amd.com/en/support/download/linux-drivers.html

  


  I installed AMF as well, and compiled my own ffmpeg build with --enable-amf flag.

  


  Still in ffmpeg -hwaccels I get access to vaapi and drm only.

  


  Can you share if you know any solution to this enigma ?

  


  These are the instructions with which I installed the drivers, AMF and ffmpeg with :

  


  Install AMD GPU Pro Drivers:
wget https://repo.radeon.com/amdgpu-install…60203-1_all.deb
sudo apt install ./amdgpu-install_6.2.60203-1_all.deb

amdgpu-install --usecase=amf,multimedia -y
sudo amdgpu-install -y --usecase=amf,graphics --accept-eula --opencl=rocr,legacy --vulkan=amdvlk,pro
