NDI Capture is ideal for mobile video gaming or presentations that happen on a smartphone. NDI Capture captures the screen of a smartphone and makes the video available as NDI. NDI Camera turns a smartphone into an NDI camera. NDI offers two smartphone applications that can be used to send video in two different ways. Example: Using NDI® as an input Perhaps the most popular way to use NDI as an input in OBS is with a smartphone. The entire production can run on a Mac, PC, or Linux computer and then be distributed across the network to another computer where you want the video to be displayed. In this way, you can use all the tools in OBS to create a dynamic presentation with live video and other sources. Another popular use of OBS is to output the production to another computer as a display. As long as both computers are on the same local area network (LAN), the video should be crystal clear and reliable with minimal latency. One computer is set up to output NDI and the other simply uses NDI as an input source. Because OBS is free, it has become a go-to solution for creating NDI video and sending it out into a LAN.Ĭonnecting two computers with OBS is very easy with NDI. So why is OBS so important to the NDI ecosystem overall? NDI essentially opens up thousands of new video input and output opportunities for OBS users. Therefore, the plugin provides a legal way for OBS to interface with NDI.

NDI itself is royalty-free, but the code is not open source. All code in the OBS project must be 100% open source. It’s worth noting that OBS will never have native support for NDI. Once you create a dedicated NDI output filter you can name the NDI source and click “Apply Changes.” Once done, your NDI source will be made available on your network. Here you can choose to apply a dedicated NDI output with both audio and video or a dedicated NDI output just audio-only. To access this filter, you can right-click on any source and select the “ Filters ” option. This is an ideal way to take a specific source and make a dedicated NDI output available on your network regardless of whether it is in preview or program.
The latest version of the NDI plugin for OBS also includes a special NDI filter that can be applied to any audio or video source in OBS. Once you have done this your NDI video sources coming from OBS will be discoverable on your local area network (LAN).
Simply check the outputs you want to send via NDI, give them a name and press OK. You can send the “ Main Output ” which is your “ Program ” window in OBS Studio and you can send your “ Preview Output ” which is your “ Preview ” window. This area allows you to send two main NDI outputs. You can send NDI video out of OBS easily using the NDI Output Settings found in the Tools dropdown menu. NTP settings are so important to IP video, they will be covered in more detail in an upcoming chapter. Your network should have an NTP server in place or you can use a commonly used server such as or. Most NDI video sources can be set up to synchronize with a common Network Time Protocol (NTP) server. NDI is able to synchronize multiple cameras or video feeds together using time codes that can come from the device itself or the network. ” An important option to understand when using multiple NDI cameras is called Sync. ” You can also choose to connect with “ audio-only. The current OBS plugin integration allows you to connect to NDI sources in two bandwidth modes “ highest ” and “ lowest. This allows you to name the NDI source and search through a list of available NDI sources on your network. You can bring NDI video sources into OBS using the “ NDI Source ” option available in the sources menu. The nice thing about NDI is its ease of use when discovering video sources on your network.
Once installed the plugin allows users to bring NDI audio and video sources into OBS and send NDI audio and video sources out of OBS.

NDI is royalty-free and the plugin that Palakis has developed uses the royalty-free software development kit (SDK) to add NDI functionality into OBS. NDI itself is not open source and therefore it can not be developed into the core OBS application. Over the past few years, Palakis has made regular updates and improvements to the plugin. As of 2022, shows the NDI plugin has been downloaded over 1.7 million times. The plugin was originally released in June of 2017 by a french developer named Stéphane Lepin with the user name Palakis. The NDI plugin is available for OBS Studio users on Mac, PC, and Linux computers. NDI was released in 2015, and it has since become one of the most popular IP video production connectivity options for professionals around the world. NDI stands for Network Device Interface and it is an IP video production protocol originally developed by NewTek.
