Setting up NDI Local Network Feed with OBS on a Windows 10 Computer using Onboard Network Adapters

In this article, we will discuss how to set up a Network Device Interface (NDI) local network feed using OBS (Open Broadcasting Software) on a Windows 10 computer with onboard network adapters. The goal is to segregate video data from internet data, which is important for a variety of reasons, such as reducing latency, improving bandwidth, and enhancing security.

What is NDI?

NDI is a high-performance video over IP protocol developed by NewTek. It allows video and audio to be sent over a local area network (LAN) with low latency and minimal impact on network bandwidth. NDI is commonly used in live production, broadcast, and streaming applications, where real-time video feeds are critical.

What is OBS?

OBS is a free and open-source software for video recording and live streaming. It supports a wide range of video and audio sources, including NDI, and can be used to create professional-quality broadcasts and streams. OBS is available for Windows, Mac, and Linux.

Setting up NDI with OBS on Windows 10

To set up NDI with OBS on a Windows 10 computer with onboard network adapters, follow these steps:

1. Download and install the latest version of OBS from the official website: https://obsproject.com/
2. Download and install the NDI Tools from the NewTek website: https://www.newtek.com/ndi/tools/
3. Launch OBS and go to "Settings" > "Output" > "Output Mode" and select "Advanced".
4. In the "Multiplex Method" dropdown, select "NDI".
5. Click "Start Streaming" to start the NDI output.
6. On another computer on the same network, launch the NDI Watcher application from the NDI Tools.
7. In the NDI Watcher, select the NDI output from the OBS computer.
8. The NDI feed will now be available on the other computer for use in other applications that support NDI, such as vMix, Wirecast, or Resolume.

Configuring Network Adapters for NDI

To ensure optimal performance and segregation of video and internet data, it is recommended to configure the onboard network adapters on the OBS computer as follows:

1. Go to "Control Panel" > "Network and Internet" > "Network and Sharing Center" > "Change adapter settings".
2. Right-click on the primary network adapter (the one connected to the LAN) and select "Properties".
3. Uncheck "Internet Protocol Version 6 (TCP/IPv6)" and click "OK".
4. Right-click on the secondary network adapter (the one connected to the internet) and select "Properties".
5. Check "Internet Protocol Version 6 (TCP/IPv6)" and click "OK".

This configuration will ensure that the primary network adapter is used for NDI traffic, while the secondary network adapter is used for internet traffic. This will help reduce latency, improve bandwidth, and enhance security for the NDI feed.

Using Magewell NDI Decoder

If you want to output the NDI feed to a physical display or projector, you can use a Magewell NDI decoder. The Magewell NDI decoder is a hardware device that converts NDI streams to HDMI or SDI signals. It can be connected to a display or projector and configured to receive the NDI feed from the OBS computer.

To use the Magewell NDI decoder, follow these steps:

1. Connect the Magewell NDI decoder to the display or projector using an HDMI or SDI cable.
2. Connect the Magewell NDI decoder to the LAN using an Ethernet cable.
3. Launch the Magewell NDI decoder software on a computer on the same network.
4. In the Magewell NDI decoder software, select the NDI feed from the OBS computer.
5. The NDI feed will now be displayed on the ```python display or projector.
   • NDI is a high-performance video over IP protocol for low-latency, real-time video feeds.
   • OBS is a free and open-source software for video recording and live streaming.
   • To set up NDI with OBS on a Windows 10 computer with onboard network adapters, install OBS and NDI Tools, configure OBS to output NDI, and use the NDI Watcher to receive the NDI feed on another computer.
   • To configure network adapters for NDI, use the primary network adapter for NDI traffic and the secondary network adapter for internet traffic.
   • To output the NDI feed to a physical display or projector, use a Magewell NDI decoder.
