#Configure broadcast software

You or your application users need to be able to push an RTMP stream. To broadcast a live stream, you’ll need a stream key.

Here are several ways to find your stream key:

  • Login to the Livepeer.com Dashboard, navigate to the streams list page, livepeer.com/app/user, and click on a stream name. Then copy your secret stream key.
  • When you create a stream object with a POST request to https://livepeer.com/api/stream, note the value of the streamKey in the response.
  • Make a GET request to https://livepeer.com/api/stream/{id}, and note the value of the streamKey in the response

When configuring broadcast software to push streams, use the secret streamKey and the Livepeer.com RTMP ingest URL, rtmp://rtmp.livepeer.com/live.

Depending on the software used to push your RTMP stream, you’ll be prompted for the following:

  • Stream Key: In some cases, this is called a "Stream Name." Input your Livepeer.com streamKey not the name of your stream.
  • Server URL: Input the RTMP ingest URL, rtmp://rtmp.livepeer.com/live.
  • Location or URL: Input the ingest url with the streamKey appended. For example, rtmp://rtmp.livepeer.com/live/{streamKey}.

#Optimization: Set keyframe intervals

Livepeer works best with consistent, short keyframe intervals, ideally 2 seconds.

You should set or encourage your users to set this in their broadcasting software. In OBS, you can set this by going to "Settings" --> "Output", change the "Output Mode" from "Simple" to "Advanced" and set the "Keyframe interval" to 2.
