The Sphere can only stream to a single destination at a time using the Sphere app.
For example, a single stream can be sent to Facebook Live, YouTube Live, Wowza Streaming Engine or your own RTMP server that is capable of accepting the stitched stream from Sphere.
Streaming to multiple destinations simultaneously requires a subscription to the Teradek Core service.
When used with Core, the Sphere app can send multiple RTMP or MPEG-TS streams simultaneously by way of the Core-controlled Sputnik server.
