| Description | Just a dead simple package to create readable streams from connected webcams |
| Node Version | >=12 |
You'll need OpenCV 4 or newer installed before installing.
Install OpenCV using brew
brew update
brew install opencv@4
brew link --force opencv@4- The object returned from createStream is a full readable Stream - you can pause, resume, destroy, pipe, etc.
- createStream optionally takes a camera number and defaults to 0 for the primary camera.
- Each data event is a full image buffer from the camera.
- Image buffers are PNGs.
- To convert the buffer to a base64 data uri (for the browser) just do
data:image/png;base64,${buffer.toString('base64')}
const camera = require('camera')
const webcam = camera.createStream()
webcam.on('data', (buffer) => {
// do something with image buffer
})Returns an error and one image buffer to the given callback. Useful if you just want to grab a simple photo.
Returns an array of video frames for the time-span specified in milliseconds.
const fs = require('fs')
const camera = require('camera')
const webcam = camera.createStream()
webcam.on('error', (err) => {
console.log('error reading data', err)
})
webcam.on('data', (buffer) => {
fs.writeFileSync('cam.png', buffer)
webcam.destroy()
})
webcam.snapshot((err, buffer) => {
})
webcam.record(1000, (buffers) => {
})
