But it won't do you any good if you don't install this version of libreElec. To make this addon work you need SDL 2.04 which is not in the release of libreelec 7.0.1. : MEGA
(This version has the jack audio server installed with alsa-plugins but it should not matter)
I tried the addon by building it for my build. It's a generic one with an ATI HD5850. It works, but the video decoding is buggy. Lots of artifacts and there's no way to remove them even if i change the bitrate settings and the force video acceleration setting.
