CaféMP – Experimental Media Player for the Nintendo Wii U

About

CaféMP is a lightweight, open-source media player for the Wii U, focused on basic media playback from the SD card. It supports most common video and audio formats, targeting up to 720p at 30 FPS.

This is a work-in-progress—expect occasional crashes, stutters, or other instability. I'm not a specialist in FFmpeg, Wii U homebrew, or C++.

Made with ❤️ in 🇩🇪

Note: 720p30 is the goal, not a guarantee. Playback performance depends on encoding complexity.
