We modified ImaAdsLoader to support feature we called Smart seek. It means, ads will not start when another ad was played within defined amount of time. In other words, timeline has 5 ad breaks, when you seek between first and second one, IMA will start playing first ad break. Immediately after the end of the ad you seek between second and third one, but at this time, ad will start because media playback does not exceed time threshold to play next ads.

I sent you source code of modified ImaAdsLoader on email. All my modifications are marked with MARK TOM. Please set adWatchThreshold to 25 seconds (25000) and use this VMAP that has ad breaks every 20 seconds. Player plays the preroll, skips first midroll and plays second midroll. We need to update AdPlaybackState before the first midroll and that cause 1 second buffering that is unacceptable for our client.

Could you please help us? Is there any solution how to prevent from buffering when update AdPlaybackState? Can we implement this feature by another way?

Thanks!
