SpoutBrowser - Chromium Browser with Spout Video Output

SpoutBrowser is a Chromium-based browser with built-in Spout texture output support.

It lets you use any web content - WebGL scenes, shaders, generative visuals, interactive pages, Strudel, Three.js experiments - as a real-time video source inside VJ and projection mapping software such as Resolume Avenue, MadMapper, or any other Spout-compatible tool.
