Things people build with this

USE CASE 1

Build a telemedicine or video consultation app that needs sub-second latency between doctor and patient.

USE CASE 2

Set up a live online classroom or auction platform that accepts OBS streams and scales to many simultaneous viewers.

USE CASE 3

Deploy IP camera monitoring by ingesting RTSP streams and distributing them through a web interface.

USE CASE 4

Add live video to a mobile app using the provided iOS, Android, React Native, or Flutter SDKs without implementing the streaming protocol yourself.

Requires a dedicated Linux server or cloud instance, Enterprise Edition needs a paid license for production use beyond the 14-day trial.

The Community Edition is free and open source, the Enterprise Edition requires a paid commercial license.

In plain English

Ant Media Server is an open-source video streaming server you can run on your own infrastructure. Its main purpose is to get live video from a camera or encoder, process it, and send it out to viewers with very little delay. The headline number is around half a second of latency when using WebRTC, a browser-native technology for real-time video. It also accepts incoming streams in several other formats including RTMP (common for broadcasting software like OBS), SRT (a newer protocol built for unreliable networks), and RTSP (used by IP cameras). On the output side, it can convert a single incoming stream into multiple quality levels automatically, so viewers on slow connections get a lower-resolution version while viewers on fast connections get a higher one. This is called adaptive bitrate. It also supports HLS and CMAF, which are the standard formats used for large-scale video delivery, so you can feed into conventional CDN infrastructure if needed. The server is used in industries where low-delay video matters: telemedicine consultations, live auctions, online classrooms, gaming streams, and security camera monitoring. The project offers SDKs for iOS, Android, React Native, Flutter, and JavaScript so developers can build apps that send or receive video without implementing the protocol layer themselves. Deployment options cover most environments. You can install it directly on a Linux server using a provided script, or pull it from AWS, Azure, and Google Cloud marketplaces as a one-click instance. Docker and Kubernetes setups are also supported. The project publishes a CloudFormation template for auto-scaling on AWS. There are two editions: a Community Edition that is free and open source, and an Enterprise Edition with additional features, technical support, and a paid license. The README links to a 14-day trial for the Enterprise version.

Copy-paste prompts

Prompt 1

I want to set up Ant Media Server on a Linux VPS to stream from OBS to a web page with WebRTC. Walk me through the installation script and a minimal test stream.

Prompt 2

Show me how to use the Ant Media Server REST API to list active streams and get the viewer count for each one.

Prompt 3

I'm building a telemedicine app. How do I configure Ant Media Server so two users in a browser can video call each other with WebRTC at under one second delay?

Prompt 4

Help me write a Docker Compose file that runs Ant Media Server Community Edition with a reverse proxy so it serves on HTTPS port 443.

Prompt 5

How do I configure adaptive bitrate in Ant Media Server so viewers on slow connections automatically get a lower-resolution stream?
