|Description||Create readable streams from connected webcams|
|Node Version||>= 0.4|
Use node-opencv's VideoStream
This library requires that you have OpenCV installed - go to the OpenCV site for instructions.
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 main camera
Each data event is a full image buffer from the camera - the framerate is variable on your CPU (should be an option in the future). 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')
camera = require 'camera'webcam = camera.createStream()webcam.on 'data', (buffer) -># do something with image buffer
Returns an error and one image buffer to the given callback.
Returns an array of video frames for the time-span specified in milliseconds
fs = require 'fs'camera = require 'camera'webcam = camera.createStream()webcam.on 'error', (err) ->console.log 'error reading data', errwebcam.on 'data', (buffer) ->fs.writeFileSync 'cam.png', bufferwebcam.destroy()webcam.snapshot (err, buffer) ->webcam.record 1000, (buffers) ->
