Add live RTMP presentations

Mediasite allows you to stream live presentations, using RTMP, from third-party streaming services such as OBS Studio and Wirecast Go. Once you add the presentation, you will specify the stream key and Server URL on the streaming service. You are then ready to stream live. You can share the link with your audience or include it in a channel. Your audience can then view the live stream in Mediasite Player the same way they would with other presentations.

 Live streaming from 3rd party streaming services is available as a limited release. For more information on enabling this feature, contact your sales account representative or our technical support  team on the  Customer Care Portal.

 

 My Mediasite considerations: Currently, all live RTMP presentations must be created in Management Portal. To make presentations available to My Mediasite users for live streaming, create them in folders that have been shared to My Mediasite. Then assign the appropriate permissions to users who will be responsible for configuring the live stream.
