Ok, I have found and installed "libamfrt64.so".  Comes with amdgpu-pro.
aptitude install amf-amdgpu-pro

So, getting closer to a possible solution.

Are their any example/sample C++ programs for Linux demonstrating how to
use the API?
I am interested in decoding H.264 on the GPU and getting the decoded frame
into opencl.

Kind Regards
