Stream realtime low-latency h264 video directly to the browser. Comes with a browser player, and streaming server. Uses Broadway browser decoder and player. Ideal for for Raspberry pi cam streaming.
const AvcServer = require('ws-avc-player/lib/server')
const { WebSocketServer } = require('@clusterws/cws') // works with ws, legacy uws
const wss = new WebSocketServer({ port: 3333 })
const avcServer = new AvcServer(wss, 640, 480) //initial width and height (it adapts to the stream)
avcServer.setVideoStream(h264Stream)More detailed in example/index.js
