go-rtmp#
A production-ready RTMP server in pure Go. Zero external dependencies.
Stream from OBS/FFmpeg → go-rtmp server → multiple viewers + FLV recording + multi-destination relay.
What is go-rtmp?#
go-rtmp is a lightweight, high-performance RTMP server built entirely on Go’s standard library. It receives live audio/video streams from tools like OBS Studio or FFmpeg, and can simultaneously:
- Relay streams to unlimited subscribers in real-time
- Record streams to FLV files on disk
- Forward streams to external RTMP servers (YouTube, Twitch, custom CDNs)
- Notify external services via webhooks, shell scripts, or stdio hooks
- Authenticate publishers and subscribers with pluggable token-based validation
- Monitor live metrics via HTTP
