Hi Gourav,
Thank you for reaching out to us.
With regard to your concern, please do note the SDK will automatically play mid-rolls at their scheduled time. You just need a Video Ad Serving Template (VAST) that has a Mid-roll video position setup to it. You may want to check these articles for relevant information.
If you have further questions specific to creative (VAST), I would recommend posting your concern to Ad Manager Help forum. The product specialist there would be able to provide a better insight regarding this.
On the other hand, if you want to override the default ad break schedule and configure your own ad break playback timings, then you may want to check our
Manual Ad Break playback guide as your reference.
Regards,
Teejay Pimentel
