Callaba Streaming Engine contains a set of streaming functionality that you can use to develop your own application. You can do that by interacting with the engine via the REST API.

Callaba Streaming API provides the following functionality
• Organizing video streaming via SRT, RTMP, MPEG-DASH, HLS in your application
• Recording broadcasts
• Embedding video into your infrastructure

At its core, Callaba Streaming API is a RESTful API based on HTTP requests and JSON responses.

Supported technologies:

  • SRT Gateway API,
  • Restream API,
  • RTMP Streaming API,
  • Player API,
  • Stream Recordings API.

Here is a simple example of a request to create an SRT Gateway using the REST API.

In this request the following data is indicated:

“server_name”: “Awesome SRT server”, // The name of the future gateway
“server_type”: “SERVER_TYPE_SRT”, // Use SERVER_TYPE_SRT if you want to create an SRT Gateway“server_port”: 1935, // UDP Port that this server will occupy“server_latency”: 200, // SRT network delay“server_maxbw”: -1, // SRT maximum bandwidth“server_timeout”: 60, // Connection timeout“server_rcvbuf”: 48234496, // Server listener buffer“server_active”: true // Enabled yes/no

This code is just an example of a request and may differ slightly from the actual request in Swagger.
