Reddit users thevincentasteroid and MMD3_ posted about an auto-playing video ad (with sound) on the home screen. The ad is for Chicken Tender Wraps from Carl’s Jr. When it begins auto-playing, it pushes all the other UI elements out of focus and goes almost full-screen, returning to the home screen after it has played through once.
Plex will do all/most of that with no additional hardware required. Just install the app to your smart TV and phones. Best part is when I go to a anyone else’s house it’s as easy as installed the app to their TV and using the QR code on the display to sing in with my phone. Bonus you install the server app to your home computer and put in movies or media you already own there. You don’t even have to install a server for it to use all of the other aggregation features.
