Spout is a system for Microsoft Windows for GPU accelerated sharing of graphics between applications in a similar way to Syphon for OSX. Spout supports DirectX 9, DirectX 11 and OpenGL textures. The installer includes a virtual webcam, utility programs and saves system settings required for correct operation. There is also a comprehensive SDK with example code for creating your own applications.


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. Unzip the distribution file to any convenient folder.



Nothing is installed on your system that runs in the background or prompts for upgrades or optional software or anything else like that. None of your system information is collected at any time. Spout installations have absolutely no advertisements or third-party software of any kind and can be easily and cleanly uninstalled from your system.
