Wii U browser can play MP4 files from a computer

The Wii U browser has a bit of a secret video playback function. It would appear that most, if not all, MP4 video files should be viewable through a computer.

Essentially, all that’s required is to set up a simple web server and upload the desired files. Then visit the server by entering your IP address in the URL bar, click on the video you wish to see, and that’s it! There’s a slightly more in-depth explanation here.

Video playback is limited to MP4 files. Other file types such as AVI and MKV aren’t compatible.

Thanks to Jackson for the tip.
