If you just want a single client without the whole server setup, then something like the Raspberry Pi Kodi media center might interest you more. It really is a fantastic home media solution. The Plex client is supported on a ton of devices including Windows, Apple, Android, Amazon Fire TV, Chromecast, Xbox, PlayStation, Linux, and so much more. It is great as you don’t need to have multiple copies of the same media across several devices. You can then have multiple clients connect to the same server. In this case, we will be using the Raspberry Pi. This setup means you can have all your movies, music, and photos located on the one device, the server. Plex is a client-server setup where the client directly streams data from the Plex media server. You can also set it up to be accessed outside your local network. This project is perfect for anyone who wants to have a media server that can be accessed by anyone within a household. In this tutorial, I go through all the steps to getting your very own Raspberry Pi plex server up and running.
