Tvheadend

I’ve a general question: I tried the last weeks without success to find a setup for tvheadend transcoding (actual version 4.3 self-compiled) with hardware acceleration on an odroid XU4Q. Is somebody out there who is using an XU4Q for tvheadend transcoding?
If yes - which os version is used, which ffmpeg and which tvheadend compiler options and setup is used?
If no - which minicomputer is working with tvheadend transcoding?
Thanks for hints and help!
Best regards
Hannes
