Restreamer

Restreamer (by datarhei) is a self-hosted live streaming relay that receives a live input stream, optionally transcodes it, and forwards it to one or more outputs. It focuses on making common streaming workflows easy through a browser-based UI while still exposing an API and Docker-first deployment.

Key Features

• Ingest live streams via RTMP and other supported protocols (via the underlying streaming engine)
• Restream/relay to multiple destinations (e.g., YouTube Live, Twitch, Facebook Live, custom RTMP endpoints)
• Optional transcoding and re-encoding using FFmpeg (e.g., bitrate/codec changes)
• Browser-based management UI for configuring inputs/outputs and monitoring status
• Docker-based deployment with persistent configuration and simplified updates
• HTTP API for automation and integration with external systems
• Designed to run on modest servers and edge devices, depending on transcoding load

Use Cases

• Mirror one live stream to multiple platforms simultaneously
• Receive RTMP from OBS and forward it to a CDN/ingress point over a controlled network path
• Centralize live stream routing/transcoding for events, churches, classrooms, or community broadcasters

Limitations and Considerations

• Transcoding is CPU/GPU intensive; capacity depends heavily on FFmpeg settings and available hardware acceleration

Restreamer is a practical option when you need a controllable, web-managed live streaming “hub” that can ingest a stream once and distribute it to many destinations. It is especially useful for simple restreaming setups and small-to-medium live production workflows that benefit from Docker deployment and API control.
