Simulcast a Wowza ClearCaster Facebook mode broadcast on Facebook Live and Wowza Streaming Cloud

You can use the Wowza ClearCaster™ appliance in Facebook mode as a video source for live streaming to Facebook Live with the Wowza Streaming Cloud™ service. This way, you can simultaneously broadcast (simulcast) your stream to Facebook and to a Wowza Streaming Cloud hosted webpage, a custom target, or a Wowza CDN edge resource. This article describes how to set up a live stream in Wowza Streaming Cloud that uses Wowza ClearCaster as its video source, enabling you to configure the ClearCaster to simulcast a live video stream to Facebook and Wowza Streaming Cloud.

  • This workflow requires you to have a Wowza Streaming Cloud subscription in addition to a Wowza ClearCaster appliance. Vist the Wowza Streaming Cloud product page for information on the features and benefits of using Wowza Streaming Cloud.
  • Simulcasting doesn't work with redundancy because individual simulcast targets can only be associated with a single ClearCaster.

Create a live stream in Wowza Streaming Cloud

To connect your ClearCaster appliance as a video source for Wowza Streaming Cloud, you first need to create a live stream and generate a connection code.
  1. Sign in to Wowza Streaming Cloud.
  2. Follow the steps in the Wowza Streaming Cloud getting started article to Add a live stream, making sure to do the following:
    • When asked What is the name of your live stream?, enter a descriptive name. This name is displayed in Wowza ClearCaster Manager as the name of the simulcast target that your producer must select when configuring the broadcast to simulcast.
    • When asked What camera or encoder will you use to connect to Wowza Streaming Cloud?, select Wowza ClearCaster.
    When you click Finish, Wowza Streaming Cloud creates your live stream and displays the Overview tab of the live stream detail page.
  3. Copy the Connection Code on the Overview tab. You'll use this code with your ClearCaster so that it can communicate with Wowza Streaming Cloud.

  4. Then, on the Broadcast page, create a new broadcast or edit an existing broadcast:
  5. On the broadcast details page, under Simulcast, select the simulcast target to which you'd like to simultaneously broadcast the stream. (Note that the simulcast target has the same name as the live stream you created in Wowza Streaming Cloud.)

Finally, when you're ready to start your broadcast, you can start both instances of the broadcast from within Wowza ClearCaster Manager.
