This tutorial applies to Windows OS and MXWendler versions 6.0 and above.


Spout is an open source video frame sharing system for Microsoft Windows, which allows sharing of OpenGL textures between applications in a similar way to Syphon for the Mac.
There are multiple numbers of Softwares and Applications which can send and receive video through Spout. Through this interconnectivity of Windows-based video and music application, Spout opens up a wide range of creative use to be applied to MXWendler.
In this tutorial, we will send and receive video through Spout, in and out of MXWendler.

Spout Software

1. Download and install the latest version of Spout from their website:


2. There are two test modules provided by the installation that can send and receive Spout as a way of monitoring your Spout signal flow and connection.

You should be able to find them in C:\Program Files (x86)\Spout2\DEMO (at the time this tutorial is written)

3. SpoutReceiver.exe will receive any Spout signal and show it as an output. In the software you can choose which Spout source you want to monitor. We will use SpoutReceiver to make sure that MXWendler is sending out Spout signal.

4. SpoutSender.exe will send a Spout stream out for you to test your Spout connection in other sotwares. We will use the SpoutSender to send Spout to MXWendler as a sample media.
