Please Note: You must restart your computer once you install the NDI addon.
NDI the royalty free bidirectional technology for IP transport of video, audio, metadata and communications using standard networks. In layman terms, it allows you to stream your skype video/audio call!
To download NDI, just go here
Click on the "Download" button. You will be taken to Github. Go to the bottom of that page, and download the version for your operating system. For example, for windows, I downloaded "obs-ndi-4.6.0-Windows-Installer.exe"
Once you download the file, install it. Restart your computer.
Then go to OBS, click on the "+" icon in sources, and you will see NDI as a source.
Please Note: You will not be able to use NDI until you are in a call in skype.
