Yes, Emby could be considered a competitor to Kodi. Using a dedicated server on your media computer to organize your media may be preferable to allowing Kodi or a MySQL database do it. The content is accessed by using a remote client. Kodi can be an Emby client by using the Emby for Kodi add-on. I think this add-on is compatible with all skins, but some skins are better designed to work with the add-on.

Emby for Kodi works well with DSPlayer but requires path substitution is used for all sources. This is described in the set-up guide.

So, Emby/Plex are server/client applications, while Kodi is best described as a standalone media frontend/server.

I've now tried with only installing Emby as a skin in Kodi just like any other skin, and it is working fine with DSPlayer, so no need for installing any Emby Server I'm using Ember Media Manager to manage my movies.
