Kodi Emby addon and external player problem

Hello,
I'have a part of my movie library located on a dedicated server running emby server and plex media server.
I've just received my Zidoo X9S and everything works fine however, it is impossible to play movies with external player. I think it's related to the source being Http. Problem is the same with Plex kodi connect addon.
Is there a possible workaround or are there any plan to support Http source with external player?

Thanks
