VPAID mode

The available VPAID modes are as follows:

1. ENABLED: This mode permits the use of VPAID ads with the default settings.

2. INSECURE: This mode allows the use of VPAID ads in an insecure mode (friendly iframe).

By default, the IMA SDK utilizes a secure iframe to render VPAID 2 JavaScript creatives, which prevents direct access to the parent page's DOM. If a creative requires access to the parent page's DOM, it may result in errors. To render your ad in a friendly iframe (same domain) instead, you can use the INSECURE mode.

In the ENABLED mode, the IMA HTML5 SDK does not directly provide the actual video element to the ad. Instead, it provides a proxy element that mimics much of the functionality of a standard video element. This approach enhances security and ensures proper mobile functionality.

While these differences don't affect the implementation code for the player or SDK, they are critical considerations for ensuring that VPAID 2 JavaScript creatives work seamlessly within the IMA HTML5 SDK environment.
