The following are used for communication between the VUER app and a supported Teradek encoder:
- Device Discovery : the VUER app uses the Bonjour / multicast DNS protocol for device discovery. This takes place on 220.127.116.11 port 5353/UDP, and requires the following service names:
_tdstream._tcp.local. These advertisements are sent out from the Teradek encoder's IP address to that corresponding multicast DNS IP address, port and service names.
- Device Communication : communication and configuration commands are sent from the VUER app to the Teradek encoder's IP address on port 80/TCP (HTTP) and port 2020/TCP.
- Video Stream : ports for streaming video are dynamically assigned between 49513/UDP and 65535/UDP; these streams will be sent from the Teradek encoder back to the iPhone or iPad running the VUER app on these randomly assigned ports.
If there are blocks on sending to broadcast or multicast addresses this could still prevent inter-device communication on your network, and you would not be able to use the VUER app.
If there is access point / client isolation on the Wi-Fi network this would also prevent inter-device communication and prevent the operation of the VUER app.
Access point isolation is common on public networks such as coffee shops, hotels, airports, or other venues.
