I am currently trying to learn the basics of VAST ("Video Ad Serving Template") and VPAID ("Video Player-Ad Interface Definition"). My goal is to show an overlay ("widget") over a video in a VAST/VPAID-enabled video player (like Flowplayer with Bigsool's DFP plugin or JWPlayer Advertising). The widget should consist of a DIV with HTML and enable interaction like mouse-over.
I am not looking for any scripting on the video player page as the widget should be delivered programmatically via a video ad server, so pure VAS and VPAID only.
There are many examples with Flash SWF files, but with Flash losing market share, I would like to work with plain Javascript only. Can you provide or hint me to an documented example with a working VAST and VPAID file?
