WebRTC-Streamer is a WebRTC streaming application that ingests video from V4L2 capture devices, RTSP sources, screen capture, and other media formats, then delivers them over WebRTC to web clients.
The tool solves the problem of exposing diverse video sources through a modern, low-latency streaming protocol. It works by accepting input from multiple source types—including local video devices, network streams via RTSP or RMTP, MKV files, and desktop capture—and transcoding or forwarding them as WebRTC streams. A simple HTTP signaling mechanism handles stream negotiation, and the tool supports the WHEP interface for standards-based client interaction. An optional compression mode using native frame buffers allows H264 frames to be forwarded directly from V4L2 devices or RTSP streams with reduced CPU overhead, though this disables resizing, codec selection, and bandwidth adaptation.
Adoption suits projects needing to stream from embedded devices, IP cameras, or desktop sources to web browsers with minimal latency. The tool is available as both standalone packages and Docker container images. It runs on platforms supporting V4L2 (Linux and similar systems) and includes Windows support for screen and window capture. The simple command-line interface accepts listening port configuration compatible with civetweb syntax, and streams can be referenced by alias, direct URL, or protocol-prefixed identifiers like v4l2://, rtsp://, or screen://.
Development activity shows ongoing maintenance with regular updates to dependencies and bug fixes. The project accepts pull requests addressing specific issues and improvements. Documentation is maintained in the repository including API specifications and usage examples. The tool is distributed through multiple channels including GitHub releases and Docker Hub, indicating sustained infrastructure support.
