#IMA SDK Plugin for Video.js
##Introduction The IMA SDK Plugin for Video.js provides a quick and easy IMA SDK integration for the Video.js player.
The framework is currently in beta, allowing interested developers to try it out and send feedback before we finalize the APIs and features.
To see the plugin in action, check out our samples.
##Features
- Easily integrate the Google IMA SDK into Video.js to enable advertising on your video content.
##Requirements
- Your favorite text editor
- A JavaScript enabled browser
##Getting started The easiest way to get started is by using npm.
npm install videojs-ima
If you don't use npm, you can download the source from the src/ 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="//vjs.zencdn.net/4.5/video-js.css" rel="stylesheet">
<link rel="stylesheet" href="path/to/videojs.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="//vjs.zencdn.net/4.5/video.js"></script>
<script src="//imasdk.googleapis.com/js/sdkloader/ima3.js"></script>
<script src="/path/to/videojs.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 = {
id: 'content_video',
adTagUrl: 'YOUR_AD_TAG'
};
// This must be called before player.play() below.
player.ima(options);
player.ima.requestAds();
// 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();
// This must be called after player.ima(...) above.
player.play();That's all there is to it!
The plugin accepts additional settings beyond the two required settings shown in the previous snippet. A summary of all settings follows:
{
id: <string> REQUIRED The id of your video player
adTagUrl: <string> REQUIRED IF adsResponse IS NOT PROVIDED A URL which returns a VAST, VMAP or ad rules
response.
adsResponse: <string> REQUIRED IF adTagUrl IS NOT PROVIDED The VAST, VMAP, or ad rules response to use
in lieu of fetching one an ad tag.
adLabel: <string> Replaces the "Advertisement" text in the ad label. Added for multilingual UI support.
adsRenderingSettings: <Object> JSON object with ads rendering settings as defined in the IMA SDK
Docs(1).
autoPlayAdBreaks: <boolean> Whether or not to automatically play VMAP or ad rules ad breaks. Defaults
to true.
contribAdsSettings: <Object> Additional settings to be passed to the contrib-ads plugin(2), used by
this IMA plugin.
debug: <boolean> True to load the debug version of the plugin, false to load the non-debug version.
Defaults to false.
forceNonLinearFullSlot: <boolean> True to force non-linear AdSense ads to render as linear fullslot.
If set, the content video will be paused and the non-linear text or image ad will be rendered as
fullslot. The content video will resume once the ad has been skipped or closed.
locale: <string> Locale for ad localization. This may be any ISO 639-1 (two-letter) or ISO 639-2
(three-letter) code(3). Defaults to 'en'.
nonLinearWidth: <Number> Desired width of non-linear ads. Defaults to player width.
nonLinearHeight: <Number> Desired height for non-linear ads. Defaults to 1/3 player height.
numRedirects: <Number> Maximum number of VAST redirects before the subsequent redirects will be denied,
and the ad load aborted. The number of redirects directly affects latency and thus user experience.
This applies to all VAST wrapper ads.
showControlsForJSAds: <boolean> Whether or not to show the control bar for VPAID JavaScript ads. Defaults to true.
showCountdown: <boolean> Whether or not to show the ad countdown timer. Defaults to true.
vpaidAllowed: <boolean> (DEPRECATED, please use vpaidMode).
vpaidMode: <google.ima.ImaSdkSettings.VpaidMode(4)> VPAID Mode. Defaults to ENABLED. This setting
overrides vpaidAllowed.

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
autoPlayAdBreaksto 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.
