# Ensure correct setup on the RTMP upstream system
<a name="setup-uss-rtmp-pull"></a>

An operator at the upstream server must set up the source content on the upstream system. Make sure that the operator sets up as follows:
+ They set up to deliver the correct number of sources:
  + If the MediaLive channel is a standard channel, set up two sources for the content. Make sure that the two source contents are identical in terms of video resolution and bitrate.
  + If the MediaLive channel is a single-pipeline channel, set up one source for the content. 
+ They set up to make the content available at the agreed URLs, and they use the agreed application names and instance names. These URLs are the URLs that you obtained [earlier in this section](setup-mp4-obtain-info.md), and that you configured into the RTMP input. They correspond to the URLs shown in [the diagram after this procedure](setup-result-rtmp-push.md).
