## What it is
A JavaScript library that plays live H.264 video streams in the browser by wrapping the Broadway WebGL-accelerated decoder, with NAL units split server-side and transported over WebSocket. It is designed for low-latency feeds such as a Raspberry Pi raspicam raw H.264 stream.

## Use cases
- play a live h264 stream from a raspberry pi camera in the browser
- view raspicam video feed with low latency without mp4 boxing
- decode h264 baseline profile frames in the browser via websocket
- build a simple surveillance or webcam viewer without plugins
- stream ffmpeg webcam output to an html5 canvas player

## When to choose
- you need real-time (no buffering) h264 video in the browser
- your source is a raspicam or ffmpeg raw h264 baseline stream
- Media Source Extensions / mp4 muxing latency is unacceptable

## When to avoid
- you need audio in the stream (video only)
- your video uses h264 profiles other than baseline
- you need a maintained, feature-rich player like MSE-based or WebRTC solutions
