I need FFMPEG syntax examples for AMD AMF hardware acceleration on Ubuntu 22.04

Question

I built FFMPEG with AMD AMF enabled. Everything seems to be compiled properly with the AMD AMF headers.

Now I have never executed FFMPEG commands over Ubuntu terminal.

I did some googling and couldn't find any proper guide on how to make FFMPEG to do some video H.264 encoding or converting using the AMD AMF hardware acceleration.

I only found guides for VAAPI but not for AMD AMF.

What are some of the FFMPEG basic syntax for using the AMD AMF hardware acceleration?

This is what I get output from Ubuntu 22.04 terminal when I enter:

$ ffmpeg -h encoder=hevc_amf
