Worked on enhancing video encoding capabilities for the THEOplayer/documentation repository by delivering new features to the ad-engine configuration. Focused on introducing additional properties for source options and track selectors, these updates enabled trim options and overlay filters, allowing for more granular control over video ad encoding. The work centered on updating YAML configuration files, applying principles of configuration management and API development to ensure robust change traceability and repository-level collaboration. These enhancements improved encoding customization for advertisers, supporting better ad quality and targeting while streamlining the process for publishers to adopt new encoding features without major workflow disruptions.
