Video keeps playing after pausing it (while playing ads via IMA)

[davlasq]

Description

I use IMA for playing ads in my player. I have this setup for months and everything was fine until recently. The problem is video and ad are playing at the same time. I pause video before playing ad but it keeps playing. I can only replicate this problem on Chrome on Android but other users claim to have this issue in different scenarios. In production it happens very often but on my CodePen example only sparingly.

What I'm doing exactly: I have two endpoints for VAST responses - one internal source (which is often empty) and one external which I use when internal one fails. I need to request them from my domain so I manually fetch this endpoints and put response into IMA.

It goes like like this:

1. User presses play or autoplay happens
2. Video is paused - the issue is here, sometimes it keeps playing
3. First VAST is fetch but it's empty
4. Second VAST is fetched and put into IMA
5. Ad is playing
6. Ad is finished and video is resumed - when problem happens video is already in progress

I tried manually checking if ad is playing and pausing video if so but it doesn't fix the problem and breaks playback on iOS.

4. Refresh if problem is not happening

The videojs-ima repo would be a better place to get help for this. googleads/videojs-ima#1098 is possibly the same or related.

Yes, this is the same issue. Thanks
