What is OVA?

The foundation of OVA is an open source (GPL3), ActionScript 3 framework that implements the IAB VAST 1.0 and 2.x standards. The framework supports the delivery of linear (pre/mid/post) video ad (MP4/FLV) and interactive (SWF) streams, non-linear (overlay) interactive (SWF) and non-interactive (image, html, text) overlays, along with companion advertising.

On top of that framework, we have built commercial implementations as plugins for the JW Player and Flowplayer. As such, OVA consists of four products:

The source code is available for all of the products, though only OVA for AS3 is open source and licensed under GPL. Extensive documentation on each of the OVA products is available on the  OVA Community Site.

OVA in Action

A wide range of  examples are provided with the  OVA documentation to illustrate the range of capabilities delivered by both the OVA for AS3 framework, and the individual player plugin implementations.

You can also try our new  VAST and VPAID Validators - example players that allow you to test your VAST ad tags with OVA. We have a validator for  Flowplayer and  JW Player 5.

In addition, the technology is deployed on a large number of commercial sites, each successfully delivering IAB compliant video advertising.

Are you successfully using the technology? If so, please let us know - it helps to share experiences across the community.


In broad terms there are two sets of licensed product on offer by Open Video Ads:

  • The OVA for AS3 framework issued under dual (GPL3 and commercial) license terms
  • OVA Player Plugins issued under a commercial license

A detailed account of the OVA licensing agreements can be found  here.
