API

Webrtc2images.startVideo(function (err) { .. })

Initiates video streaming

Webrtc2images.recordVideo(function (err, frames) { .. })

Captures video into an array

Example

var Webrtc2images = require('webrtc2images');
var rtc2images = new Webrtc2images({
  width: 320,
  height: 180,
  frames: 10,
  type: 'image/jpeg',
  quality: 0.4,
  interval: 200
});
 
rtc2images.startVideo(function (err) {
  if (err) {
    console.log(err);
  }
});
 
var recordBtn = document.getElementById('record');
recordBtn.addEventListener('click', function (ev) {
  ev.preventDefault();
  rtc2images.recordVideo(function (err, frames) {
    if (err) {
      console.log(err);
    } else {
      console.log(frames);
    }
  });
});

Here's some markup that the lib needs, at some point I can refine this...

<div class="video-actions" id="record">
  <span class="recorder"></span> <span class="text">Record</span>
</div>
<div id="video-preview"></div>
<div class="debugger">
  <p id="debug-msg">
</div>
