Node.js implementation of the W3C Media Capture and Streams

node-media-capture

Node.js implementation of the W3C Media Capture and Streams

##Features

Currently supports the following APIs:

• MediaStream
• MediaStreamTrack
• MediaDevices
• MediaRecorder (partially)
• ImageCapture (partially)

###Specs

• Media Capture and Streams
• MediaStream Recording
• Mediastream Image Capture

####Difference from W3C APIs

• MediaRecorder's ondataavailable() returns node's Buffer instead of ArrayBuffer.
• ImageCapture's takePhoto() returns node's Buffer instead of Blob.

###Status

• Currently supports Mac OS X only. (tested on MBP + Yosemite.)
• Currently supports video tracks only. (audio is being implemented.)
• MediaRecorder's recording operations (pause/resume) are not supported.
• ImageCapture's settings are not supported.

##Install

Note that only the Mac OS X is supported.

$ git clone [e-mail]:kuu/node-media-capture.git
$ cd node-media-capture
$ npm install

##Run

Run the sample app:

$ npm start

Go to http://localhost:8080/ with your browser.

##Usage

import NMC from 'node-media-capture';

let navigator = NMC.navigator,
    MediaRecorder = NMC.MediaRecorder,
    ImageCapture = NMC.ImageCapture;

navigator.mediaDevices.getUserMedia({video: true})
.then(
  (stream) => {
    // Video capture
    let recorder = new MediaRecorder(stream);
    recorder.ondataavailable = (buf) => {
      console.log('----- Video captured. size=' + buf.length);
    };

    // Image capture
    let capture = new ImageCapture(stream.getVideoTracks()[0]);
    capture.takePhoto().then((buf) => {
      console.log('----- Image captured. size=' + buf.length);
    });
  },
  (e) => {
    throw e;
  }
);
