“Spout” is a video frame sharing system for Microsoft Windows, which allows sharing of OpenGL textures between applications in a similar way to Syphon for the Mac. Read the Documentation.



“SpoutControls” is a programmer aid to develop a controlled Spout Sender that will react to controls specific to the application. Examples for Openframeworks, Cinder and Processing can be used as a guide for developing others. The “SpoutController” FreeframeGL plugin adapts it’s user interface to that of the Sender so that you can forget about the sender app itself. Read the Documentation.

Spout to NDI


“Spout to NDI” is a set of programs that allow Spout senders and receivers to share video, not only with each other but also by way of a network using the NewTek NDI (“Network Device Interface”) protocol version 4.0. Read the Documentation.

As well as the converter programs, there are 32 and 64 bit modules developed specifically for Magic Music Visuals for sending to and receiving from NDI. Binaries and source code are available on GitHub. And, if you want to do your own thing, there is an addon for OpenFrameworks.

Nothing is installed on your system that runs in the background, and none of your system information is collected at any time. Spout installations have absolutely no advertisements or third-party applications of any kind and can be easily and cleanly uninstalled from your system at any time.
