Unable to add VideoAdPlayerCallback to ImaAdsLoader in latest version 2.12.0

[Manvendra-Jadon]

I am getting an error, where video force closes before playing mid-roll ad. Here is the stack trace for the same:

I tried upgrading ima extension to latest version, but i am unable to add callback, which is required on my end.

Please could you share the ad tag here or email it to dev.exoplayer@gmail.com with subject "#7944"? Thanks.

@andrewlewis Details sent through email(dev.exoplayer@gmail.com).

I tried upgrading ima extension to latest version, but i am unable to add callback, which is required on my end.

On the latest version I can't reproduce the problem (the ad tag has two empty ads with cue points "0" and "-1" (postroll) but both are located correctly).

Could you give some more details about what information you need from VideoAdPlayerCallback? The same information should be available via player listeners, so there may be an alternative way to implement what you're trying to do.

@andrewlewis If you see screenshot, when i am upgrading from 2.11.5 to 2.12.0, i am not able to add this callback showing in red. Because of this i am unable to check anything on latest version.

Also, stack-trace mentioned in the bug: #7322
is the same i get when video force closes before playing mid-roll.

[andrewlewis]

What events to do you handle in your VideoAdPlayerCallback? I am wondering if you can replace those with listening to events on the player to avoid needing to add a callback. See also #6249.

[Manvendra-Jadon]

@andrewlewis We handle onPlay(), onEnded(), onError(). Is there no way to add this callback on latest version? As this is lot of effort on my end to change this and will surely break few things.

Also, what about this:
