What network ports are needed for streaming with Live:Air, Live:Air Action and Live:Air Solo?

Outbound RTMP Streaming

RTMP streaming is typically handled on port 1935/TCP for most providers such as IBM Cloud Video, Livestream, Vimeo, or YouTube Live.

Two exceptions are Facebook Live which streams RTMPS on port 443/TCP, and Periscope which streams RTMP streaming on port 80/TCP.

To ensure that you are able to send out your stream:

• the firewall on the network must not filter or block outbound communication on these ports
• the firewall on the network must not be performing content filtering / policy rules blocking access to these sites, especially sites which may be categorized as social media (Twitter/Periscope, Facebook, YouTube)

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

Airmix / Live:Air-enabled Sources

The following are used for communication between Source devices --  which includes compatible Teradek encoders in Airmix / 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 Airmix Remote app -- and the devices running Airmix, Airmix Solo or Live:Air Action:

• Device Discovery : the Airmix and Airmix Live:Air Remote apps use the Bonjour / multicast DNS protocol for device discovery. This takes place on 224.0.0.251 port 5353/UDP, and requires the following service names: _device-info._tcp.local and _tdstream._tcp.local
• Device Communication: communication and configuration commands are sent between Airmix, Airmix Solo, Live:Air Action and Live:Air Remote or Teradek encoder devices to the broadcast IP address of the network on which they are operating, on port 21572/UDP. Additional communication between the Live:Air app and Teradek encoder devices takes place on port 80/TCP (HTTP) and port 2020/TCP.
• Video Stream : Airmix 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 Airmix / Airmix Remote / Live:Air Action.

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 Airmix, Airmix Remote or Live:Air Action.

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.
