The anatomy of RTMP URL

Every RTMP URL has these parts:

  • Server and application name, e.g. rtmp://yourserver.com:1935/live or rtmps://192.168.0.1/app. It has a protocol prefix, a domain or URL, a port (optionally) and an application name. For YouTube Live it would be "rtmp://a.rtmp.youtube.com/live2"
  • Stream name or Stream key. It's also usually some alphanumeric stream name. E.g. for YouTube Live it's like "abcd-efgh-abcd-efgh".

Combine these parts to create a URL to insert into Connection URL field in Larix Broadcaster settings (see the links to full instructions below).
For example if you see Primary Server URL in YouTube Live as "rtmp://a.rtmp.youtube.com/live2" and Stream Name as "abcd-efgh-abcd-efgh", then your full URL will be "rtmp://a.rtmp.youtube.com/live2/abcd-efgh-abcd-efgh".
