How to Live Stream from Microsoft Teams (RTMP) to Webcastcloud

This guide explains how to broadcast a live event from Microsoft Teams to Webcastcloud using RTMP.

This setup allows you to:

• Use Teams as your production environment (presenters, screen share, etc.)
• Deliver the stream through Webcastcloud for branded viewing, monetisation, and audience engagement.

Before You Start

Make sure you have:

• A Webcastcloud Streaming Software Live Stream created.
• Your RTMP URL and Stream Key from Webcastcloud.
• Access to Teams Live Events or Town Hall (RTMP output required).

Step 1: Create Your Live Stream in Webcastcloud

1. Log in to Webcastcloud admin portal.
2. Go to Library > Content > Add New.
3. Click Live Stream > Streaming Software > Fill out streaming details > Save.

After your livestream is created, you'll want to save the following details: 

1. Click on the Media Info tab:
   
2. Click Live Studio
3. Click the Info icon in the top right:
   
    
   • Copy RTMP Server URL
   • Copy Stream Key

You’ll use these in Microsoft Teams.

Step 2: Schedule a Teams Live Event / Town Hall

In Microsoft Teams:

1. Go to Calendar
2. Click the arrow next to New 
3. Select:
   • Town Hall (recommended) or
   • Live Event (legacy option)
4. Enter event details (title, presenters, etc.)
   
   

Step 3: Enable RTMP Output in Teams

When setting up the event:

1. Go to Event Settings
2. Enable:
   • External app or device (RTMP output)

Once enabled, Teams will provide:

• RTMP Server URL

You will replace these with Webcastcloud’s RTMP details

Step 4: Configure RTMP Output to Webcastcloud

In the Teams RTMP settings:

• RTMP Server URL → Paste from Webcastcloud
• Stream Key → Paste from Webcastcloud

Save your event.
 

Step 5: Start the Stream

1. From Live Studio (In Webcastcloud)
2. Click Prepare to Go Live
3. You will see the Go Live button once the livestream server is running. 

Now do the following from teams:

1. Join the event as a presenter
2. Click Start Event
3. Begin your presentation (camera, screen share, etc.)
   

In Webcastcloud: 

1. Confirm the stream is being received
2. Once you're happy with the livestream preview click Go Live to begin streaming to your audience.
