Unreal Engine 4 Media Framework plug-in for NewTek's Network Device Interface (NDI).



NDI™ (Network Device Interface) is a standard created by NewTek to make it easy to develop video-related products that share video on a local Ethernet network (video over IP). This plug-in makes NDI media input streams available in Unreal Engine 4.

Make sure to pull the Tag that matches your Unreal Engine version. If you sync to Master the code may not compile, because it may depend on Engine changes that are not yet available in the UE4 Master branch.

Supported Platforms

This plug-in was last built against Unreal Engine 4.19 and NDI SDK 3 on the following platforms:

  • Linux (untested)
  • macOS (untested)
  • Windows


Strarting with 4.19, the required NDI header files and libraries are no longer included in this plug-in. Instead you must download and install the NewTek SDK for your platform. Verify that the NDI_SDK_DIR environment variable is set on your computer. Follow the NDI SDK Documentation for installation instructions.

The users of your project must have the NDI Redist package for the desired target platform package installed. It contains the NDI run-time libraries that are required for this plug-in to work. You should bundle the redistributable package installer with your project installer. Installation of the NDI SDK is not necessary on end user machines.


This plug-in requires Visual Studio and either a C++ code project or the full Unreal Engine 4 source code from GitHub. If you are new to programming in UE4, please see the official Programming Guide!


You can use this plug-in as a project plug-in, or an Engine plug-in.

If you use it as a project plug-in, clone this repository into your project's /Plugins directory and compile your game in Visual Studio. A C++ code project is required for this to work.

If you use it as an Engine plug-in, clone this repository into the /Engine/Plugins/Media directory and compile your game. Full Unreal Engine 4 source code from GitHub is required for this.
