VAST to SGAI Conversion service

OVERVIEW

The VAST to SGAI Conversion Service is an open-source tool designed to transform standard VAST (XML) ads into HLS or DASH Asset Lists, enabling Server-Guided Ad Insertion (SGAI). By simplifying the workflow and removing the need for expensive SSAI infrastructure, this service empowers developers to integrate targeted ad breaks more efficiently and prepare for next-generation SGAI tracking features.

KEY OBJECTIVES

  • Seamless Ad Conversion: Turn VAST URLs into ready-to-use AssetLists (HLS) and ListMPD (DASH) for immediate integration.
  • Broad Player Compatibility: Ensure compatibility with native iOS players, hls.js, and ExoPlayer environments.
  • Simplified Configuration: Offer multiple configuration options (JWT, whitelists, and parameter dictionaries) for flexible, secure setups.

CHECK OUT OUR KICK-OFF

RECENT UPDATES & MILESTONES

  • Functional Service: The service now fetches Asset Lists from a given VAST URL for seamless integration.
  • Query Parameters: Three parameters allow customization of VAST URLs and conversions.
  • Plugin Development: A plugin-based approach for SVTA event tracking is in progress, following discussions with Rob Walch (hls.js). If widely adopted, it could be integrated into the player.
  • Demo: A demo of hls.js 1.6 beta2 showcased successful VAST event mapping and tracking requests.
  • Terraform Templates: Templates are under development to simplify deployment.
  • Next Steps: Refinements and updates will be published on vast2sgai.qualabs.com

Future Enhancements: Integration of SVTA Ad Creative Signaling specs and dynamic interstitials for improved scalability.
