With Socialive, you can stream to any platform that supports RTMP.
When you set up an RTMP stream, you can choose to store it for one-time use or save it to your Account for future broadcasts (also called "Persistent").
If you choose to save the RTMP settings, other broadcasters will be able to choose it as an output connection in other broadcasts.
Simply copy and paste the RTMP Server URL and Streak Key into Socialive. Click on the check box to Save as a Persistent RTMP (if relevant) and click on the SAVE button as seen in the screenshot below:
