Most livestreams on the Internet currently use the RTMP protocol to deliver the stream for its wide adoption and low latency advantage. With that being said, if you are using Castr for your streaming production, you might find yourself needing a static RTMP address for the team. 

For a successful connection using the RTMP protocol, you need an RTMP server URL and an RTMP stream key. Enabling Castr’s constant RTMP address helps you and your team to use the persistent details at any point when streaming. 

Note that this feature is available in Castr’s Multistream plans and upon request in Livestream plans.
