In the coming weeks, we’ll be making changes to the way the IMA HTML5 SDK handles AdSense and Ad Exchange non-linear and full slot ads. You should be aware of these changes to ensure that your video player behaves as expected once the changes have taken effect.
A non-linear ad is a static or animated ad that displays over the video content during content playback. These are also sometimes referred to as “bottom-third” ads, because they typically take up the bottom third of the video player. A non-linear ad.
A full slot ad is a static or animated ad that usually appears before or after the content, occupying the entire view area. It renders a close button that when clicked closes the ad and, if rendered before the content, triggers the content to start. A full slot ad.
Currently, non-linear ads are rendered as expected, but full slot ads are also rendered as non-linear ads. So instead of pausing, the video continues to play underneath them while they take up a large portion of the video display.
With the new behavior, any non-linear AdSense or Ad Exchange ad greater than 90 pixels in height will be rendered as a full slot ad. This means it will take up the entire video display. When the user clicks the close button, the content will start.
We will also be adding a new UI to these full slot ads which includes a countdown timer and a skip button. You should remove any custom UI elements you’ve added for full slot ads to ensure there are no conflicts with this new UI.
Lastly, to ensure that your ads are rendered properly, make sure your AdDisplayContainer is rendered on top of everything else and takes up the full size of your video player. Full slot ad with the updated UI.
Testing the changes
If you’d like to test these changes, you can load the test version of our SDK by replacing your load of ima3.js with ima3_test.js. This is a watermarked test binary that changes frequently and without notice; it is not intended for use in production.
As always, if you have any questions, feel free to contact us via the support forum.
