Hi TPmodding thanks for getting back to me, I've loaded config as requested. I was running Hyperion on its own pi hence the forwarder using a different IP. I've now got everything running (including Hyperion server) on libreelec 8 with kodi 17 as Hyperion wouldn't install on version 7.0.10 (its documented on here). The only way I could get it too capture anything was too stick the Hyperion Kodi capture addon and sending that too local host.
As I'm using the kodi add-on grabber I have to switch off H.264 acceleration otherwise the lights just go nuts. When its enabled video plays fine so the build can play these files without issues, its only when using Hyperion which I think is down to the kodi grabber. Its not clear from what ive read but do you need to activate the X11 grabber through the config via Vl42 grabber section and change to the grabber in there.
Thanks again
