Use defaults
Ubuntu 20.04 LTS (or 22.04 LTS)
Associate an EIP public IP
Connect to the CLI
Download NDI SDK.
Go to: https://www.ndi.tv/sdk/
Download the NDI SDK from NDI site to your PC.
In NDI Instance Linux CLI create NDI directory in /home/ubuntu
scp the NDI SDK to /home/ubuntu/NDI
unarchive the NDI SDK: sudo tar -xf Install_NDI_SDK_v5_Linux.tar.gz
Note: version (v5) may change according to what is current NDI SDK
make the unarchived .sh file executable:
sudo chmod +x Install_NDI_SDK_v5_Linux.sh
run: sudo ./ Install_NDI_SDK_v5_Linux.sh
The script creates a directory: ’NDI SDK for Linux’
Rename /home/ubuntu/NDI/’NDI SDK for Linux’ to ndi-sdk
mv /home/ubuntu/NDI/’NDI SDK for Linux’ /home/ubuntu/NDI/ndi-sdk
ndi-sdk
Create a systemd Service to Run the NDI Discovery Server in the Background and Restart on Boot.
cd /etc/systemd/system/
Create a new file where you will define the NDI Discovery service:
sudo nano ndi-discovery.service
Write the following in the file:
cd bin
Note: Make sure that the directories in the above script are correct. These may change in different NDI versions so check the /home/ubuntu/NDI… directories.
Save the file and quit.
A json file must be created to configure the discovery server.
In directory /home/ubuntu/NDI/ndi-sdk/bin/
Create file as shown below: sudo nano /home/ubuntu/NDI/ndi-sdk/bin/ndi-config-v5.json
Insert the public address of the NDI Discovery server, between the “ “
Example:
“discovery”: “<public IP>” becomes "discovery": "52.44.134.94" or whatever your public IP is
