startOnView: The entire player is loaded only when in view. This means that only when the player’s position is in view, the player will load and start. This flag requires using player templates/studio
(Note that the Inventory metric will be sent only after the player is in view and loaded)
Once it loads, the player will continue without validating viewability.reqOnView: If set to TRUE, the player will call all ad sources (i.e. send a request to them) when in view. If the player is not in view, it will wait until it is and then it will resume the process.
This flag does not requires require using player templates/studio, but it is subject to other configurations such as midrolltime.playOnView: If set to TRUE, the player will call the ad sources also when not in view and initialize VPAIDs, but will initiate the Ads (startAd) only when in view.
This flag requires using player templates/studio.
(Note that due to the nature of some VPAIDs and SDKs, calling startAd does not guarantee an Ad Impression of the specific Ad Source)vitab: If set to TRUE, Viewability validation will take into account if the tab is in view or not. The default is false.
playOnViewPerc: Defines the required % of view that defines if the player is in view or not. Default is 50%
This applies to all features.
