Build and Track Multiple Videos Code Snippet – Sizmek Help Center

Quick Start Guide

Note: This section deals with setting up and tracking multiple videos within a single html5 video player. For the full snippet to copy/paste please skip to the advanced section.

Summary

This Video Player code snippet provides the means to enable Sizmek Video Tracking within an ad using standard HTML5 video objects for display ads (NOT in-stream). This guide will document both “auto tracking” as well as manual tracking of video interactions for multiple video assets within a single video player.

How to Build

Add the EB Video Module include in the head of your Workspace index.html file. Be sure to add this before adding the adkit include.
```
<script type="text/javascript">EBModulesToLoad = ['Video'];</script>
```
Add a video tag with video source to the body of your index.html file. Add any attributes you may need such as controls or autoplay. A list of commonly used attributes is included below.
```
<video id="video" controls autoplay>
	<source src="videos\sizmek.mp4" type="video/mp4" />
	Your browser does not support the video tag.
</video>
```

Once adkit has loaded, instantiate the EB Video Module and pass the video element reference to the video module.


<script type="text/javascript">
    // Establish reference to video tag
    var theVideo = document.getElementById("video")
    // Create video module instance to track video events
    var trackedVideo = new EBG.VideoModule(theVideo);
</script>

Use the setVideoSrc API method to update the video module so that it tracks a new video asset


<script type="text/javascript">
    // update video player source
    theVideo.src = "videos/sizmek2.mp4";
    // use API to update video source in video module
    trackedVideo.setVideoSrc(theVideo.src);
</script>

Full Code Snippet

Please see the full script, below, needed to implement the video player into your ad.

Note: the code snippet below does not include styling which can affect the display and layout of the page. In the absence of styling, the video will load at the width and height of the video source possibly leading to undesirable results.

Known Issues

Due to the limited event data associated with native controls for HTML5 video, it is difficult to determine the origin of certain events as they pertain to video tracking. For instance, while we can track whether a custom play button built in javascript was clicked by the user, there is no reliable way to determine if the user clicked on the native play button, making it difficult to ascertain if the event was user-initiated. Likewise, it is difficult to determine if the "seeked" event is being fired because the user dragged the playhead, or if the user clicked the replay button. Similarly, if the video tag includes the "loop" attribute, the "seeked" event is fired automatically as the playhead updates. Please keep this in mind when using manual tracking.
When user the playVideo method with the EB.videoModule, please note, that the "IsUserInitiated" integer for the "ebVideoStarted" interaction will report as a 0. For manual tracking, the USER_INITIATED_VIDEO event must be fired for metrics to properly record user-initiated video. Additionally, once the user-initiated value is set to true, it will always be true for that impression.
