Videojs-ima NPM

IMA SDK Plugin for Video.js

Introduction

You can use the IMA SDK Plugin for Video.js to integrate with the Video.js player.

If you're using the plugin for a DAI implementation, see the DAI readme for documentation.

To see the plugin in action, check out our samples.

Features

Integrate the Google IMA SDK into Video.js to enable advertising on your video content.

Requirements

Your favorite text editor
A JavaScript enabled browser

Get started

ES6 Imports

The easiest way to get started is to use npm.

npm install videojs-ima

Your index.html should contain the video.js stylesheet (not included in the npm module), a video player to be used for playback, and script tags for the IMA SDK and your own javascript file.

<html>
  <head>
    <!-- Load dependent stylesheets. -->
    <link href="path/to/video-js.css" rel="stylesheet">
    <link href="path/to/videojs.ima.css" rel="stylesheet"/>
  </head>

  <body>
    <video id='content_video' class="video-js">
        <p class='vjs-no-js'>
            To view this video, please enable JavaScript and consider upgrading to a web browser that
            <a href='https://videojs.com/html5-video-support/' target='_blank'>supports HTML5 video</a>
        </p>
    </video>
    <!-- Load dependent scripts -->
    <script src="//imasdk.googleapis.com/js/sdkloader/ima3.js"></script>
    <script src="player.js"></script>
  </body>
</html>

Three imports are required to use the videojs-ima module, as seen in the player.js example below.

import videojs from 'video.js';
import 'videojs-contrib-ads';
import 'videojs-ima';

var videoOptions = {
  controls: true,
  sources: [{
      src: 'PATH_TO_YOUR_CONTENT_VIDEO',
      type: 'YOUR_CONTENT_VIDEO_TYPE',
  }]
};

var player = videojs('content_video', videoOptions);

var imaOptions = {
  adTagUrl: 'YOUR_AD_TAG'
};

player.ima(imaOptions);
// On mobile devices, you must call initializeAdDisplayContainer as the result
// of a user action (e.g. button click). If you do not make this call, the SDK
// will make it for you, but not as the result of a user action. For more info
// see our examples, all of which are set up to work on mobile devices.
// player.ima.initializeAdDisplayContainer();

Alternative Setup

If you don't use npm, you can download the source from the dist/ folder and include it directly in your project. You'll also need to download the source for the videojs-contrib-ads plugin.

In your index.html file, create a new video.js player and load a (currently empty) javascript file:

<html>
  <head>
    <!-- Load dependent stylesheets. -->
    <link href="path/to/video-js.css" rel="stylesheet">
    <link rel="stylesheet" href="path/to/videojs-contrib-ads.css" />
    <link rel="stylesheet" href="path/to/videojs.ima.css" />
  </head>

  <body>
    <video id="content_video" class="video-js vjs-default-skin"
        controls preload="auto" width="YOUR_VIDEO_WIDTH" height="YOUR_VIDEO_HEIGHT">
      <source src="PATH_TO_YOUR_CONTENT_VIDEO" type="YOUR_CONTENT_VIDEO_TYPE" />
    </video>
    <!-- Load dependent scripts -->
    <script src="/path/to/video.js"></script>
    <script src="//imasdk.googleapis.com/js/sdkloader/ima3.js"></script>
    <script src="/path/to/videojs-contrib-ads.js"></script>
    <script src="/path/to/videojs.ima.js"></script>
    <script src="player.js"></script>
  </body>
</html>

In player.js, load the ads library and set up the IMA plugin:

var player = videojs('content_video');

var options = {
  adTagUrl: 'YOUR_AD_TAG'
};

player.ima(options);
// On mobile devices, you must call initializeAdDisplayContainer as the result
// of a user action (e.g. button click). If you do not make this call, the SDK
// will make it for you, but not as the result of a user action. For more info
// see our examples, all of which are set up to work on mobile devices.
// player.ima.initializeAdDisplayContainer();

Additional settings

The plugin accepts additional settings beyond the two required settings shown in the previous snippet. A summary of all settings follows:

Settings	Type	Description
adLabel	string	Replaces the "Advertisement" text in the ad label. Added for multilingual UI support.
adLabelNofN	string	Replaces the "of" text in the ad label (e.g. ... (1 of 2) ...). Added for multilingual UI support.
adTagUrl	string	A URL which returns a VAST, VMAP or ad rules response. This will override adsResponse.
adsRenderingSettings	object	JSON object with ads rendering settings as defined in the IMA SDK Docs(1).
adsResponse	string	The VAST, VMAP, or ad rules response to use in lieu of fetching one an ad tag. This is overridden if adTagUrl is set.

autoPlayAdBreaks	boolean	Whether or not to automatically play VMAP or ad rules ad breaks. Defaults to true.
deprecated adWillPlayMuted	boolean	Notifies the SDK whether the player intends to start ad while muted. Changing this setting will have no impact on ad playback. Defaults to false.

IMA Plugin Ad Events

The IMA Plugin fires events that can be listened for. Ad lifecycle events can be listened for by following our Advanced Example. Other events are emited from the videojs player. Please see the below example to set up listeners for these events.

this.player = videojs('content_video');

this.player.on('ads-manager', function(response){
  var adsManager = response.adsManager;
  // Your code in response to the `ads-manager` event.
})

Below are the events added by the videojs-ima plugin to the videojs player.

Event	Event String	Payload
Ad Started	'ads-ad-started'	none
Ads Manager	'ads-manager'	google.ima.AdsManager
Ads Loader	'ads-loader'	google.ima.AdsLoader
Ads Request	'ads-request'	google.ima.AdsRequest

Disable automatic ad break playback

In some circumstances you may want to prevent the SDK from playing ad breaks until you're ready for them. In this scenario, you can disable automatic playback of ad breaks in favor of letting the SDK know when you're ready for an ad break to play. To do so:

Set autoPlayAdBreaks to false in the initial options.
Provide an ad break ready listener via setAdBreakReadyListener.
Call player.ima.playAdBreak() in your ad break ready listener when you're ready to play the ads.
