The anatomy of RTMP URL (with YouTube as example)

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”.

BTW, YouTube recommends Larix among very few mobile encoders, see more details on the setup below. Please follow their recommendations and requirements for setup as well.

Screencasting from iOS via Larix Screencaster

Apple requires additional screencasting setup for Larix Screencaster besides the streaming part.
Notice that if you stream your screen, you can only use your microphone. If currently opened application supports ReplayKit, then you’ll be able to stream its sound.
This is the limitation of iOS.
