This may be caused by several problems.
NDI uses the mDNS (Avahi daemon on Linux) to discover NDI sources. Live Transcoder in Docker already has avahi-daemon up, and another avahi-daemon on your host system can lead to a conflict. Stopping the service on your host system solves the issue. You can stop it with this command.
sudo systemctl stop avahi-daemon
This command prevents the startup of the daemon at boot.
sudo systemctl disable avahi-daemon
Stop and start your Live Transcoder container again.
- The Live Transcoder host instance is in a different VPC or subnet than your NDI source.
- Ports needed for NDI source discovery are closed in your cloud provider's firewall (Security Groups in AWS)
