Ffmpeg: amf video support with ROCm base?

Support AUR
1

Hi there, with help of ChatCPT I found that my GFX card Radeon RX7600 is capable of transcoding with AMF support to achieve best results. I’d like to stay with the open source driver amdgpu with ROCm.
ffmpeg fails with this error: ‘DLL libamfrt64.so.1 failed to open’ ffmpeg has amf capability, but where may I get the o.a. library from?

Best regards,

It seems you would need amf-amdgpu-pro from the AUR. See also AMDGPU PRO - ArchWiki.

4 February 2025

FFmpeg already has supported AMD’s Advanced Media Framework “AMF” on the video encode side while FFmpeg has landed initial “AMFDEC” support as video decoding support using AMD AMF.

This commit introduces AMFDEC to FFmpeg’s libavcodec library. FFmpeg’s AMFDEC support covers H.264, H.265/HEVC, and AV1 video decoding

ffmpeg in Manjaro extra repository has not been updated since Dec 2025, but git versions in AUR might have this commit:
AUR (en) - ffmpeg-full-git
AUR (en) - ffmpeg-amd-full-git

I had presumed the amf-amdgpu-pro package would only be usable in combination with proprietary driver - but it works now. Thx! :slight_smile:
