mjpeg-webcam-server

A webserver for streaming a webcam using FFmpeg written in node.js designed for MacOS (Linux support may come later).

The endpoints are designed to work well with OctoPrint - /snapshot for a single JPG image, and /stream for an MJPEG video stream.

FFmpeg runs independent of the webserver requests, so multiple clients are supported at once without extra transcode tasks.

Snapshots are served from the last frame already seen, so the /snapshot endpoint is quick as possible for maximum timelapse accuracy.

Requirements

• node.js 16.x or later

Status Page

This server also includes a status page to monitor it in realtime. Simply open http://localhost:3000/ to preview your camera, monitor transcode performance, see capture devices detected, and check logs.
