Node.js based application trying to mimic YouTube some but supports image, video, and audio. The platform is open source available on github: https://github.com/mayeaux/nodetube
The devs are also hosting the application at nodetube.live. No email is required to sign up.
Seems to be pretty popular on both Github and Hacker News.
Max upload size is 500MB which seems like a big issue to me. Any decent quality video around 20 minutes long would surpass that.
Edit: FYI, let me know if this is the wrong forum. I figured it fit in General since it might be a good place game resources can be posted. At the very least, tutorials and game footage. Maybe game assets as well since it supports audio and images.
