NDI Streaming Setup Guide

Use NDI to move video and audio across your network for cleaner dual-PC and multi-source setups.

NDI, short for Network Device Interface, lets you send low-latency audio and video over your local network. It can be a strong alternative to a capture card when you want a flexible dual-PC setup or need to move multiple sources between machines.

Requirements

Software

  • OBS Studio (installed on both PCs)
  • OBS-NDI Plugin (Palakis version on GitHub)
  • NDI Runtime Installer (required for plugin functionality)

Hardware

  • Two PCs on the same network, with wired Ethernet strongly recommended
  • Gigabit Ethernet for smooth high-bitrate transfers
  • Router or switch capable of handling heavy bandwidth

Installation & Setup

1. Install NDI Plugin on Both PCs

  • Download and install the latest OBS-NDI plugin.
  • Complete setup on both the Gaming PC (source) and Streaming PC (receiver).
  • Install the NewTek NDI Runtime when prompted.

2. Enable NDI Output on the Gaming PC

  • Open OBS Studio on the Gaming PC.
  • Go to Tools > NDI Output Settings.
  • Enable Main Output and give it a recognizable name (e.g., GamingPC-OBS).
  • Ensure your game scene is active in OBS.

3. Add the NDI Source on the Streaming PC

  • Open OBS Studio on the Streaming PC.
  • Add a new NDI Source.
  • Select the NDI stream you named (GamingPC-OBS).
  • The gameplay and audio should now appear live.

Audio Management

  • NDI transmits audio with video automatically.
  • Ensure Desktop Audio is active in your Gaming PC's OBS scene.
  • If sync issues occur, adjust using Network Sync Offset or OBS's audio sync settings.

Tips for Performance & Sync

  • Use Gigabit Ethernet to reduce latency.
  • Match resolution and FPS across both OBS instances.
  • Disable preview on the Gaming PC to save resources.
  • Adjust the NDI bandwidth mode (Low/Medium/High) according to network stability.
