A small library that uses getUserMedia to convert some video into an array of base64 encoded images

Requirements:

browserify

Installation:

npm install webrtc2images

options

Type: Object

Options to pass webrtc2images.

options.width:

Type: Number Default: 320

The width of the video stream.

options.height:

Type: Number Default: 180

The height of the video stream.

options.frames:

Type: Number Default: 10

The number of frames to capture.

options.type:

Type: String Default: image/jpeg

The mime type of the image you'd like.

options.quality:

Type Number Default: 0.4

A number between 0 and 1 representing the quality of the image. Note, this only works for the image/jpeg and image/webp filetypes.

options.interval:

Type: Number Default: 200

The time between still captures (in milliseconds).

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>
