Hello there!
I'm new with LibreELEC, I was using Kodibuntu till know but I decided to move a new more updated distro so I choose this one, the installation goes ok, it's really easy but I'm having problems to get HW decoding working properly, I guess that is a graphic card driver issue.
First of all I'm using and old graphic chipset, the AMD780G and the Radeon HD3200 graphic adapter here (I know pretty old but still working 
) , it was perfectly working with VDPAU decoding but no longer working, looking through log I have seen something suspect "VDPAU::Open: required extension GL_NV_vdpau_interop not found" thats makes me wonder about graphic driver, I know nothing about this distro so I don't know how to install anything (not yum or sudo here 
). Also audio passtrough is not working and I don't know why the sound is playing on stereo instead of its original format....
Any idea on how to get the graphic adapter working (installing somethig maybe)?
Below the piece of log, maybe it means something for you (I hope so)
Thanks in advanced.
