What did you do?

Try to play video with ads

What did you expect to happen?
Ads and video to play

What actually happened?

Ads work great when player is not in fullscreen.

On fullscreen, no ads are displayed. When going to fullscreen during an ad (rotating the device to landscape), the ad sound keeps playing but main video is visible (paused). If ad(s) end, video starts playing.

Are you interested in finding and create a PR to fix the error? Thanks!

@avelad I'm afraid that I'm not that familiar with Apple devices. As I use Win/Android, it would be really difficult to debug also...

[avelad]

The fullscreen API is not available on iOS (https://caniuse.com/fullscreen) so we use the fullscreen API of the video element itself and it produces this behavior.
I see two solutions:

• Disable the full screen button in browsers that do not support the fullscreen API and are using IMA CS.
• When an ad is going to be played, exit fullscreen, and disable the fullscreen button during the ad, the problem is that we cannot return to fullscreen afterwards because a user action is necessary.

Which solution do you like best? (You probably won't like any...)

@avelad Thanks for looking it up!

I guess that the best solution would be to disable the fullscreen button / rotation during the ads, if fullscreen API is not supported.

In this case user is forced to see at least preroll. And if he goes to fullscreen after preroll and doesn't get any midrolls, it's acceptable. Exiting fullscreen to display ads is a really bad user experience, I would say.

@theodab What do you think?

@Andekas @avelad Please look this blog - IMA iOS10+ customPlayback. It may provide insights on how to address the problem.
