vastTagUrl
The VAST or VMAP ad tag for videos played with playVideo, overriding the one set in the library's player settings on the Bunny dashboard. Leave it null (the default) to use the dashboard's tag; set it to an empty string to play without ads.
Ads are requested and played by the Google IMA SDK. Assign before calling playVideo; the value is read per call. Live streams always use the tag from the dashboard.
