This is a dirt-simple SDL3 program that just renders an Ogg Theora file to a window.
This is hooked up to a Raspberry Pi Zero 2 with a Pimoroni Pirate Audio Speaker, and a PiSugar S battery, with a case around it to look like a Christmas tree ornament.
It's sort of a special-case thing, but if it works for you, feel free to steal it.
