What is Spout? #

Spout is a real-time video sharing application for windows. It allows to programs running on the same GPU to share textures between them.

Before testing, if Spout is working we recommend downloading Spout and then restarting your computer.

Notch can either send or receive Spout shared textures from another program

Sending #

1. To make Notch a sender you will need to go to Project > Settings > Video In / Capture > Spout
2. Enable ‘Spout Sender’.

Receiving #

1. To receive a Spout shared texture from another program will need to go to Project > Settings > Video In / Capture > Spout
2. Enable ‘Spout Receiver’.
3. Add a ‘Video Capture’ node to the nodegraph.
4. Select ‘Spout’ as the ‘Source Type’
   
   

You will need the spout sending file open to allow the receiver to work.
