Hi,
Thank you for contacting the IMA SDK support team.
As stated in the Google IMA sample VAST tag, once the ads are loaded, it will begin playing immediately. As per the IMA documentation Preloading media, Autoplay must be enabled for preloading to work. So preloading the ad in the background and playing it only under specific conditions is not possible.
VMAP does not support concurrent playback of multiple ads. VMAP defines a sequential structure for ad playback, allowing only one ads to be played at a time. If you require multiple sequential ads, consider utilizing ad pods within the VAST tag.
