NDI and Syphon (Video Sharing)
Sharing real-time video textures between applications without using excessive CPU.
NDI (Network Device Interface)
Video over IP. Useful for sending video to/from other computers on the same network. It is cross-platform.
- Video Stream In TOP: Select NDI source.
- Video Stream Out TOP: Send NDI stream.
Syphon (macOS) / Spout (Windows)
Zero-latency GPU memory sharing on the same machine. Since you are on macOS, you will use Syphon.
- Syphon Spout In TOP: Receive video from another app (like Resolume or MadMapper) on your Mac.
- Syphon Spout Out TOP: Send your TouchDesigner video output to another app.
Note: In TouchDesigner, the node is called Syphon Spout to support both OS types, but on Mac, it utilizes the Syphon protocol under the hood.
