Odroid C2 H265 on Plex

this is my first post here :smiley:
I have recently bought an Odroid C2. I installed Samba for NAS, Transmission and (after a few problems) also Plex Media Server.
I read that there’s hardware transcoding for H265 files (1080p movies), so that the streaming via Plex is more fluid, but in my case it keeps loading after few seconds of video. I am asking if there is some option for GPU or VPU (i don’t know which it uses) accelleration or some option to activate this H265 hardware support.
Thank you :smiley:
