The Live:Air apps can only stream to a single destination at a time.
For example, a single stream can be sent to Facebook Live, YouTube Live, Livestream, Ustream, Wowza Streaming Engine or your own RTMP server.
Streaming to multiple destinations simultaneously requires a subscription to the Teradek Core service.
When used with Core, the app can send multiple RTMP or MPEG-TS streams simultaneously by way of the Core-controlled Sputnik server.
Additional information on the Core service is found below:
