I have a simple task to do but I want some of you guys' input.
So I need to set up a button that when pressed will cause a video to play on a nearby TV.
- This must happen instantly (or at most with a second or two of delay)
- Video will be "self-hosted" (not on Youtube or something) and will mainly stay the same
- No idea what kind of TV I'll get to work with (might be smart, probably not)

I'm thinking a Raspberry Pi with a button connected to it's GPIO and a static image displayed on the TV when idle. That way I can also manage/maintain it remotely via SSH and it should be reliable enough but on the other hand this could be an overkill...

Post your 2 cents please and thank you :)
