When did you install 4.0.2? This same problem was happening on arch linux a week ago, and we resolved that, although i'll have to check with our developer to see if that was fixed via another libx264 update, or an emby package update.
But in any case, it appears the manjaro package for Emby is just our arch linux package, right? If that's the case, you could try installing again.
I have been running 4.0.2 since Feb. No issues period with Emby or any/all Manjaro updates that were installed. Let me STATE..... This is not an Emby problem or even an Manjaro issue. My problem is just a simple dependency issue between 2 and more software's installed in Manjaro. The Emby-Server package in Manjaro is maintained by Manjaro contributor. It is not from AUR (an Arch package). Now... The Manjaro Maintainer/Contributor for Emby-Server maybe getting the package from Arch and not directly from Emby???? I do not know. That person's email is in one of the screen shots I posted above.
The whole issue started when the latest FFMPEG and X264 Library popped up in Update Manager for install. It's as simple as that. This is the 1st time I have experienced Manjaro's Update Manager detecting a dependency issue and refuse to install an update. I think this wise! I've been running Manjaro on and off for 3 years. In the past, dependency checks were not the norm and caused me to brick my OS many times.
If I don't see an update from you, I will uninstall Emby-Server. Let Manjaro Update FFMPEG and X264. And then reinstall Emby.
