What network ports are needed between the Sphere and the Sphere app?

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.


Sphere iPad app

The following are used for communication between the Sphere (and its (4) individual encoders) and the iPad running the Sphere App:

  • Device Discovery : Multicast DNS / Bonjour advertisements are sent out from the Sphere to IP address, port 5353 (UDP) to allow discovery by the Sphere app
  • Control : the Sphere app communicates with and configures the Sphere on HTTP / port 80 (TCP). Thumbnail image / snapshots are also obtained by the app from the Sphere over this same method when the streams are not being stitched.
  • Streaming video : ports for streaming video are dynamically assigned between 49513 and 65535; these streams will be sent from the encoders in Sphere to the iPad running the Sphere app for stitching


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 Sphere with the iPad running the Sphere 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 Sphere and Sphere app.

Access point isolation is common on public networks such as coffee shops, hotels, airports, or other venues.
