PROFILE
Joel Keers
Worked on the bbc/bigscreen-player repository to enhance secure media playback and developer tooling over a three-month period. Delivered protection data support for dash.js, enabling DRM-protected content playback by updating MediaSources and MSEStrategy to handle protection data throughout the streaming pipeline. Addressed a race condition in the MSEStrategy initialization, ensuring the media player was ready before applying protection data, and improved debug logging for faster issue diagnosis. Added a developer-facing feature to log video fragment response headers, integrating a non-intrusive debug toggle. Utilized JavaScript and TypeScript, applying skills in DRM, debugging, and full stack development to improve reliability and observability.
