SRS

SRS is available in the NetActuate Marketplace as a one-click, open-source appliance you can deploy into any NetActuate PoP. The all-protocol live streaming server (RTMP/WebRTC/HLS/SRT). It is grouped under the Media & Streaming category.

What It Does

SRS (Simple Realtime Server) is a battle-tested, MIT-licensed live streaming server that bridges nearly every streaming protocol in a single high-efficiency binary. It ingests from encoders like OBS or FFmpeg and delivers to browsers and apps over the protocol that fits each viewer, all with an HTTP API and web console for operations.

Key features

• All-protocol support: RTMP, WebRTC (WHIP/WHEP), SRT, HLS, HTTP-FLV, HTTP-TS, and MPEG-DASH
• Broad codec coverage: H.264, H.265, AV1, VP9, AAC, Opus, and G.711
• Sub-second latency paths via WebRTC and SRT for interactive streaming
• Clustering (origin and edge) to scale fan-out across many viewers
• Built-in DVR, transcoding, forwarding, and stream ingest
• HTTP API plus a web console for monitoring and control
• Runs on Linux and macOS across x86_64, ARM, AARCH64, and RISC-V
• Lightweight, single-process design that is easy to containerize

Use cases

• Low-latency live streaming for events, sports, and auctions
• Protocol conversion (for example RTMP ingest to WebRTC or HLS delivery)
• Interactive and conversational video via WebRTC or SRT
• Building a scalable origin/edge streaming cluster
• Self-hosted alternative to commercial media server licenses

Why run it on the NetActuate edge Deploy SRS in a PoP close to your audience so WebRTC and SRT sessions get the shortest possible round trip and the lowest glass-to-glass latency. Terminate ingest and fan out HLS or WebRTC at the edge to keep viewer traffic off your origin and cut rebuffering for regional audiences.

Best for: Live origin, Low-latency, WebRTC.
