Share textures over network using the Newtek NDI protocol Syphon-NDI on OS X

Convert between Syphon and Newtek NDI sources.
Using the Newtek NDI SDK
Version 2018-03-22 @ r88001

“Syphon to NDI” is a set of programs that allow Syphon 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. For more information about the NDI protocol see below.

Product requirements

  • OS: OSX 10.8+
  • CPU: NDI requires SIMD SSSE3

Syphon is created by Tom Butterworth and Anton Marini provides framework for VJ software. This framework is a library available connection between processes of image data on the identical host, and the architecture brought by IOSurface gives less delay. This utility allows image data as TCP/IP on network to realize network transparency. Compared with AirPlay, credibility might be lower, however this trait is small latency especially customized for VJ. By selecting the appropriate encode to network bandwidth you use, even on poor network environment it can carry out delivery without quality loss on image data.

Stay on Menu-Bar.

Attention "AppNap" on OSX10.9

App Nap is a new feature in OS X Mavericks that automatically reduces system resources to certain applications that are not currently in use. But we don't want to work it. Let's disable!

defaults write sg.techlife.TCPSyphonClient NSAppSleepDisabled -bool YES
defaults write sg.techlife.TCPSyphonServer NSAppSleepDisabled -bool YES

How to Disable App Nap in OS X Mavericks
