VideoLan’s VLC Media Player is a free download:
Download and run the installer, and follow the onscreen instructions to install the VLC Media Player on your system. [Important Note: The installer default is to install 32-bit VLC Media Player; if you have a 64-bit system, make sure instead to select to install 64-bit VLC Media Player - NDI is about 4 times faster on 64-bit than it is on 32-bit.]
The NewTek NDI Tools Pack is a free download
The file you download is an installer, “NewTek NDI Tools.exe”. Run the installer and follow the onscreen instructions to install the NDI Tools to your chosen system. Once installation is complete, the tools present on your system include the NewTek NDI VLC Plugin.
First, locate your VLC Media Player on the desktop and run the application. If you play a video at this time, you’ll note that the video is displayed in the player window. When we use VLC Media Player with the plugin, this won’t be the case - the video and audio will go to the network as an NDI stream.
Now, Locate the Tools menu and select Preferences and configure VLC to send video and audio to the NewTek NDI VLC Plugin
On the Preferences panel, select Audio.
On the Audio Settings, drop down the selection list for Output module, and select NewTek NDI audio output.
Next, select the Video Settings.
On the Video Settings, drop down the Output options list, and select NewTek NDI video output.
Once you have completed this selection, click the Save button to save the preferences.
Next, exit VLC Media Player, and restart it.
Start playing the video you would like to go out over NDI by pressing Ctrl+N to insert a network stream. You should paste the link to your YouTube video here.
You can also load and start a local video which will play over NDI as well.
Locate and add the NDI source in you Livestream Studio.
