Solo portal does not yet offer a multi-destination option.
Meanwhile, we have many great partners that can help you with this need.
LiveU Solo has one-touch integration with Restream.io as well as an additional option for Switchboard Live, whose customers have used LiveU products at many events and productions to reach a long list of platforms, or multiple destinations on the same platform - such as many Facebook Live pages.
We also have customers that use LiveU Solo with Livescale, among other services that offer multi-destination. These services make a great companion to your Solo!
The basic setup for such services is to point the output of your LiveU Solo - in either LRT mode or RTMP Direct mode - at the service in question. That is, you would set the ingress information from the service as your destination in LiveU Solo. That way your stream goes from Solo (or Solo cloud bonding service, via LRT) to the Multi-Destination service.
