NDI Inputs let you send video from production software like vMix or OBS into LIGR Live over your local network, so you can use that feed as the source for a match stream.
What NDI Does in LIGR Live
NDI is a network video protocol supported by LIGR Live as an Input type. Instead of sending video via RTMP, NDI lets compatible software on the same network deliver a low-latency feed directly into LIGR.
Use NDI when:
• You're producing locally with vMix, OBS (with the NDI plugin), or another NDI-compatible tool
• You want to avoid encoding to RTMP before sending video to LIGR
• You need to bring LIGR graphics back into your production software as an NDI output
Prerequisites
Before setting up an NDI Input, make sure:
• Your production machine and LIGR are on the same network
• Your encoder (vMix, OBS, or similar) has NDI output enabled
• You have a Match created in LIGR Live that you want to attach the Input to
• You have the required permissions (Owner, Admin, or Gameday Operator)
Setting Up an NDI Input
Step 1: Open Your Match
1. Click the Matches tab in the left sidebar.
2. Select the match you want to configure.
3. Open the Stream View for that match.

Step 2: Configure the Input
1. Locate the Input settings for the match.
2. Choose NDI as the Input type.
3. Select your NDI source from the list of detected sources on your network.

Step 3: Enable NDI Output on Your Encoder
In your production software, make sure the NDI output is turned on:
• vMix: Enable NDI output under Settings → Outputs / NDI
• OBS: Install the OBS-NDI plugin, then enable NDI output under Tools → NDI Output Settings
Step 4: Confirm the Feed
1. Back in LIGR, check that the Input is receiving video.
2. Preview the feed in the Stream View to confirm audio and video are both present.
Tips
• Keep your encoder and LIGR on the same wired network where possible. NDI is sensitive to network performance and works best over Gigabit Ethernet.
• Give your NDI source a clear, recognisable name in your encoder so it's easy to find in the LIGR source list.
• Test your NDI setup well before match day — ideally with a full end-to-end check into a test Destination.
• If you're using Multiview to monitor several streams, confirm each NDI Input is stable before going live.
Common Issues
NDI source not appearing in LIGR
• Confirm both machines are on the same subnet
• Check that NDI output is actually running in your encoder
• Firewall or VPN software can block NDI discovery — temporarily disable to test
Video is choppy or dropping frames
• Switch from Wi-Fi to wired Ethernet
• Reduce the resolution or frame rate of the NDI output
• Close unnecessary applications using network bandwidth
Audio is missing
• Verify the audio source is assigned to the NDI output in your encoder
• Check audio levels in the Stream View preview
Input shows connected but no video
• Restart the NDI output in your encoder
• Re-select the NDI source in the Input settings in LIGR
