Yes Plex is 100% legit but for CLOUDRON? IDK I believe this is docker based I have not USED Plex in while because most hosting companies frowned on me uploading my DVDs digitally to their storage...
IF CAN BRING PLEX OR IT IS POSSIBLE should stop all dev on everything and work on PLEX server side deployment turn key..
here is good idea if Plex is not do-able
