Inquiry on Mid-Roll URIs for Long Videos in VMAP

[Anas Mirza]

Dear IMA SDK Team,

I hope this email finds you well.

I am currently working on generating VMAPs programmatically for an Android application that plays videos or recorded streams. I have a specific question regarding the use of URIs for mid-roll ads.

For example, I have a video with a 4-hour length and plan to show mid-roll ads at 5-minute intervals. This would result in approximately 48 mid-roll ads (4 hours * 60 minutes / 5 minutes).

My question is: Do I need to use 48 unique URIs for each mid-roll ad request, or can I use the same URI multiple times across the video length? I ask this because when I attempted to use duplicate URIs with the VMAP test URIs, the ads failed to load. However, when I used unique URIs, everything worked fine.

While I can generate an infinite number of unique URIs, but the thing is Google does not recommend creating many URIs using an ads account. Could you please provide guidance on the best practice for achieving this within the recommended guidelines?

Attached the 2 vmap files generated for the long video below


Thank you for your assistance.

Best regards,
Anas
