OBS Live Streaming [Speaker Guide]

This guide will outline the major steps involved in managing OBS Studio as a Session Speaker. 

For this guide, it is assumed that there will be a Session Facilitator controlling the Live Streaming output and various screens (e.g. Interactive Sessions Display Screen). If this is not the case, please refer to the Manage OBS Live Stream [Facilitator Guide]. 

 As OBS is a desktop-based application each speaker would need to stream their content from their respective desktops. 

A facilitator can be engaged to coordinate between the speakers on the presentation schedule and handover from one speaker to another.

Please install the OBS software from here https://obsproject.com/

Configure Broadcasting Software

OBS acts as our Broadcasting Software and needs to be linked to MUX, our Distribution Platform. OBS requires the RTMP URL and the Stream Key from MUX to enable live streaming. These would be provided by the Event Organiser or Session Facilitator.

To configure OBS Studio

  1. Launch OBS Studio
  2. Click Settings on the bottom right  and then select Stream under the menu items
  3. Paste the RTMP URL from distribution platform (MUX) into the Server field
    1. This would be provided by the Event Organiser or Session Facilitator
  4. Paste the Stream key from the distribution platform into the Stream key field
    1. This would be provided by the Event Organiser or Session Facilitator
  5. Click Apply and OK

This establishes the connection between OBS and the distribution platform MUX
