Month: 2025-09 — Key feature delivered: Enhanced Bitrate Tracking via Active Quality Change Event for THEOplayer/iOS-Connector. This work refactors the bitrate observation mechanism from a notification-based approach to an integrated event-driven model that listens to the active quality change event on video tracks, delivering more robust bitrate metrics and improving adaptive streaming decisions. The change is captured in commit 0f4e534384f7e005b6f7f4c4d388156547f99912 (replace bitrate observing). Major bugs fixed: None reported this month. Impact and accomplishments: Improved accuracy and reliability of bitrate data, enabling smoother user experiences during quality transitions and providing better analytics for streaming performance. This also reduces technical debt by consolidating bitrate observation into a single, testable event-driven path. Technologies/skills demonstrated: Swift/Objective-C (iOS), video track observation, event-driven architecture, refactoring for maintainability, field-level commit tracing.
