Dynamically configuring the ad server URL for the Brightcove Player.

dynamic-ads.js

/**
 * PLUGIN CODE
 */
 
// create a simple javascript plugin that gets the current video ID and sets up ads:
videojs.plugin('setupAds', function() {
  'use strict';
  var player = this, 
      currentVideoId = player.el().getAttribute('data-video-id');
  player.ima3({
    serverUrl: '//ads.example.com/ad?q=100&anotherparam=17&video=' + currentVideoId
  });
});

/**
 * PLAYER CONFIGURATION
 */

// Below is the raw player configuration JSON, what you'd see if you were working 
// with the Player Management APIs directly. You could configure all of this through
// the studio, too. Each of the top-level properties corresponds to the fields in 
// the "Plugins" pane of the Player Details page.

// include that plugin in your player config *instead of* a plugin entry for videojs-ima3:
{
  "scripts": [
    "//players.brightcove.net/videojs-ima3/videojs.ima3.min.js",
    "//example.com/setupads.js" // the URL to the plugin javascript above
  ],
  "stylesheets": [
    "//players.brightcove.net/videojs-ima3/videojs.ima3.min.css"
  ],
  // only include plugin initialization options for the setupAds plugin
  // setupAds will initialize videojs-ima3 instead of configuring it statically here
  "plugins": [{
    "name": "setupAds"
  }]
