Outbound RTMP Streaming
RTMP streaming is typically handled on port 1935/TCP for most providers such as Livestream, Ustream, or YouTube Live.
One notable exception is Facebook Live which does RTMP streaming on port 80/TCP.
To ensure that you are able to send out your stream, make sure the firewall on your network is not filtering or blocking outbound communication on this port.
Chat for Twitch, YouTube Live, or Facebook Live
To ensure that you're able to use the chat functionality with Live:Air and Live:Air Solo, ensure that the firewall on your network is not filtering or blocking outbound communication on these ports:
- Twitch Live Chat : port 6667/TCP
- Facebook Live Chat : ports 80/TCP and 443/TCP
- YouTube Live Chat : ports 80/TCP and 443/TCP
The following are used for communication between Source devices -- which includes compatible Teradek encoders in Live:Air mode such as the VidiU, Cube or Clip, as well as iOS devices such as an iPod Touch, iPhone or iPad running the Live:Air Remote app -- and the devices running Live:Air or Live:Air Solo:
- Device Discovery : the Live:Air and Live:Air Remote apps use the Bonjour / multicast DNS protocol for device discovery. This takes place on 18.104.22.168 port 5353/UDP, and requires the following service names:
- Device Communication: communication and configuration commands are sent between Live:Air and Live:Air Remote / Teradek encoder devices to the broadcast IP address of the network on which they are operating, on port 21572/UDP
- Video Stream : Live:Air Remote and Teradek encoder devices use a randomly-assigned UDP port between 49513 and 65535 for the video stream sent back to the iPad running Live:Air
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 these Source devices in Live:Air.
If there is access point isolation on the Wi-Fi network this would also prevent inter-device communication and prevent the operation of Live:Air with local Source devices.
Access point isolation is common on public networks such as coffee shops, hotels, airports, or other venues.
