datarhei Restreamer

datarhei Restreamer is a self-hosted live streaming server that ingests video from sources like OBS or IP cameras, processes streams via FFmpeg, and publishes them to your website and/or external platforms. It combines a browser-based UI with streaming protocols and a documented API to manage inputs, outputs, and monitoring.

Key Features

• Ingest and publish using common streaming protocols (including RTMP, SRT, and HLS)
• Restream a single input to multiple outputs (e.g., social platforms or other streaming servers)
• Web-based setup wizard and streamlined administration interface
• Built-in embeddable web player and optional publication page
• FFmpeg-based transcoding and processing, including muxing separate audio
• Hardware-accelerated encoding support (e.g., NVIDIA CUDA), depending on deployment
• Bandwidth/viewer monitoring and optional limiting
• REST API with OpenAPI/Swagger documentation
• TLS automation with Let’s Encrypt for HTTPS (deployment-dependent)

Use Cases

• Publish a live stream to your own website while simultaneously restreaming to major platforms
• Centralize ingest from OBS and distribute to multiple RTMP/SRT endpoints
• Create a lightweight streaming gateway for events using commodity hardware (including SBCs)

Limitations and Considerations

• Reliable transcoding and multi-output restreaming can require significant CPU/GPU resources
• External publishing depends on the capabilities and limits of the destination platforms

Restreamer is a practical choice for organizations and creators that want to control their streaming stack while keeping setup approachable. Its UI-driven configuration, multi-protocol support, and API make it suitable for both simple live embeds and more advanced distribution workflows.
