jernej, I have registered just to THANK YOU. This is a huge thing! I have grabbed the 190324 release image, put into my Orange Pi PC Plus, booted it and it JUST WORKED! In my very quick test all the H.264 videos were replayed properly and very nicely. Woooow, finally an accelerated Kodi video playback. Thank you again, and please push it upstream so it's official part of LibreELEC. This is really great present for all Orange Pi owners out there!
P.S. Now I'd like to copy it from microSD to internal EMMC as it will be my main HTPC player now (bye bye Raspberry Pi!). I'll try to find some instructions for that. Then I'll see if I can get sleep and wake-up working and if yes then I am the happiest Kodi user 
Thanks again!
