Synchronizing Video Transitions and Loops with Audio State
Unified playback state across the mini player, lock screen, and reels so that all surfaces reference a single source of truth.
When playback state is distributed across multiple surfaces, consistent behavior cannot be guaranteed regardless of where the user initiates control — whether from the mini player, lock screen, or reels. This fragmentation does not surface in feature checklists but directly degrades the reliability of the playback experience.
The objective was to consolidate dispersed playback state under a single authoritative source. The activation and deactivation sequence of audio sessions and track loading was restructured, and video transition and loop timing was synchronized with audio state. The mini player and lock screen now read from this unified state and no longer maintain independent decision logic.
Screen flow was also standardized under the same principle. The transition from splash to initial entry was refined, and content exposure across browse and recommendation surfaces was made consistent. The primary outcome is stable, predictable behavior for core interactions such as play and pause.
