IMA HTML SDK - Use Custom Ad Playback for iPad Firebox

[WJ]

Hi IMA team,

I read that by default the SDK determines whether to use custom Ad playback based on the browser useragent, as quote from this blog:

"The HTML5 SDK looks at the UserAgent string of each browser on which it’s loaded. When it sees a browser that it knows has trouble with multiple video elements, it uses custom ad playback."

May i know if it applies to ipad browsers, especially Firefox which lacks fullscreen api support at the moment. When testing on iPad Firefox (iPadOS 18.6.2, Firefox 142.1), it seems standard rendering is used and it breaks when going to native fullscreen (no ads shown, content is freezing / black-screened). setDisableCustomPlaybackForIOS10Plus is false.

Would it be possible for the SDK to use custom playback on iPad Firefox and other browsers which lack fullscreen api support? Thank you :)

Best Regards,

WJ

Hi team, may I know if there is any update on this issue?

Hello WJ,


Thank you for following up on this thread.

Since the IMA HTML5 Rendering blog post you mentioned is from 2015, I am seeking confirmation from our engineering team regarding your questions.

In the meantime, the recommendation in this GitHub issue might resolve the problem: https://github.com/googleads/videojs-ima/issues/803#issuecomment-593565204.

Would you also be able to provide a screen recording, logs (including any error messages), and a sample project that we can use to reproduce the issue?


 

Thanks,
 

Joshua IMA SDK Team
