Introduction

With the release of Radiant Media Player 5.0.5, we support the HTML5 Google IMA DAI SDK (dynamic ad insertion). The Google IMA DAI SDK for HTML5 V3 allows publishers to request and track DAI streams in a HTML5 video environment with a server-side ad insertion angle (SSAI). We support both live and on-demand video streaming with the HTML5 Google IMA DAI SDK through HLS (hls.js based implementation).

Using the Google's dynamic ad insertion requires publishers to have an Ad Manager 360 account and an account manager.

You can test your DAI stream in our tester here.

Supported environments for the DAI IMA HTML5 SDK

Desktop: Chrome, Firefox, Safari 8+, Internet Explorer 11
Mobile: Chrome for Android 4.4+, Safari for iOS 9+

DAI streams may work in other environments with Radiant Media Player but they are not officially supported.

When version for a browser is not specified we support the latest version of this browser.

  var rmp = new RadiantMP(elementID);
  var rmpContainer = document.getElementById(elementID);
  // Get companion ad and append it to DOM when adstarted fires (if any available)
  var companionDiv = document.getElementById('companionDiv');
  rmpContainer.addEventListener('adstarted', function () {
    var companionAds = rmp.getCompanionAds();
    for (var i = 0; i < companionAds.length; i++) {
      var companionAd = companionAds[i];
      if (companionAd.getWidth() == 300 && companionAd.getHeight() == 250) {

      ads: {
        controlBarCustomMessage: 'Ads'
      }
    },
    poster: 'https://your-poster-url.jpg'
  };
  var elementID = 'rmpPlayer';
  var rmp = new RadiantMP(elementID);
  var rmpContainer = document.getElementById(elementID);
  rmpContainer.addEventListener('adstarted', function () {
    var adPodInfo = rmp.getAdPodInfo();
    var adPosition = adPodInfo.getAdPosition();
    var maxDuration = adPodInfo.getMaxDuration();
    var podIndex = adPodInfo.getPodIndex();
    var timeOffset = adPodInfo.getTimeOffset();
    var totalAds = adPodInfo.getTotalAds();
  });
  rmp.init(settings);
</script>

iOS specific considerations

On iOS Safari, last major environment where Media Source Extensions are still not available in 2018, hls.js does not go. By default if a HLS stream is provided through the adImaDaiBackupStream setting, we will use this HLS source for iOS Safari. However this does not enable ads on iOS Safari. In order to do so we need to use the client-side HTML5 IMA SDK (as opposed to the DAI IMA SDK). This can be done as follows:

// We define DAI player settings for non-iOS devices ...
var daiSettings = {...};
// ... and client-side IMA player settings for iOS devices
var iosImaSettings = {...};
var elementID = 'rmpPlayer';
var rmp = new RadiantMP(elementID);
// We detect iOS and use the relevant settings to init player
var env = rmp.getEnvironment();
var ios = env.isIos[0];
if (ios) {
  rmp.init(iosImaSettings);
} else {
  rmp.init(daiSettings);
}
