Although I'm currently trying to build LibreELEC-AML 9.2.8 with the necessary tweaks to get it running and updating on the MX2 boxes. I've stumbled at the Mozilla stuff not building on 32-bit, so I've switched to 64-bit and may have a build to try in the new year (it's not a simple task, so fingers crossed). I'm really hoping it'll sort that hanging issue with Amlogic hardware decoding.
If you think so, maybe I can help you with that.
