If you have stepped into the world of streaming protocols already, you may have come across SRT, or Secure Reliable Transport. You also probably know of RTMP, or Real-Time Messaging Protocol.

These are two of the most common protocols used in audio and video streaming. When you create a new livestream or multistream on Castr, you wil get the details for both of these protocols.

To see how they differ, check out our blog!

Get RTMP details for your stream on Castr

When you create a new stream in Castr, you can find the RTMP ingest details automatically generated in the Stream Source Setup.

  1. Open an All in One/Multistream project in Castr

  2. From the Stream Source Setup, copy the RTMP URL and Streaming Key

  3. Paste into your encoder's RTMP configuration

Note: If your encoders ask for username and password, leave the fields empty. Authentication using username and password is not required to start streaming to Castr.

Besides the RTMP details, Castr also provides you with an SRT URL in the Stream Source Setup.

  2. In the Stream Source Setup, you can find the SRT URL

  3. Copy and paste the URL to your encoder to connect using the SRT ingest

Once the encoder is configured, you will be able to start streaming. The stream will appear in the preview section in Castr Dashboard.
