Broadcasting audio and video from Teams with NDI technology

NDI® (Network Device Interface) technology allows you to broadcast the audio and video streams from a Teams meeting to your local network. 

When using NewTek NDI® technology in a Teams meeting, you will have unique video steams on the network that can be used in your own production.

Turning on NDI® technology in Teams

First, NDI®-out needs to be turned on for each individual user by an admin. Once NDI®-out has been turned on, a new option will become available in Teams.


  • An admin for the user's tenant can use cmdlets or the admin portal to enable NDI®-out.

  • NDI®-in is currently not available in Teams.

Next, select Settings and more  Select to see more options  next to your profile picture at the top of Teams and choose Settings. Then select Permissions and turn on the toggle next to Network Device Interface (NDI).

Note: All meeting attendees who have subscribed to that NDI stream will be notified that broadcasting capabilities are turned on.

NDI®-out features

Once NDI® technology is turned on, the following streams will be available:

  • Primary speaker: A stream will be generated that automatically switches to whoever is actively speaking from all of the incoming streams. (Audio/video from your own computer will not be included.)

  • Local: A stream will be generated of the audio/video that is being sent to the meeting from your computer. (This allows you to have the same audio/video in both the meeting and in your local NDI® production.)

  • Individual users: Each individual user will have a stream available over NDI®. The incoming audio for a meeting is mixed together and will be the same for all individual user streams. These streams will display the video at the same quality that is being received by the client.

    Note: If no video is available, you will see a simple screen with the Teams logo. But the stream is still being received by your NDI® software/hardware.

  • Screen sharing: Any incoming screen sharing will be available as an NDI® stream. 

  • Large gallery and Together mode: Both of these modes will have their own NDI® stream available.

Technical limitations

These are some common technical issues to consider when using NDI® Technology in Teams:

  • Broadcasting NDI® signals from Teams is limited by the number of streams and quality of the streams your Teams client receives.

  • A good strategy is to first "pin" a video stream in Teams to ensure that particular video stays connected during the meeting. Under that meeting participant's name, select More actions  Select to see more options  and then choose Pin.

  • Try limiting the number of NDI®-out video streams to two or three on any single computer. This is another good strategy that will help ensure stability and performance for most users.

  • Changing to a different meeting layout such as Together Mode or Large Gallery will stop the video streams of other people in the meeting from coming to your computer. Your machine will then only be able to stream the selected layout via NDI®. (Returning to the Gallery layout will restore the video streams.)
