The anatomy of RTMP URL
One of the most frequent questions about streaming from mobile is: how can the connection URL be specified? Since RTMP is the most common protocol used for mobile delivery, here's how it's made.
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".
Combining these parts together will create a URL which you will 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".
Notice that YouTube requires using video+audio mode for streaming and has a number of other recommendations and requriements .
Some services like Facebook Live require using SSL connection. This means the protocol prefix need to be "rtmps://" instead of regular "rtmp://".
