Worked on Dispatcharr/Dispatcharr to enhance frontend live-stream playback fidelity by ensuring user-selected output profiles and formats were consistently applied across all live stream entry points. Integrated the buildLiveStreamUrl function into getShowVideoUrl, allowing output settings to persist through the TV Guide, Program Detail modal, DVR page, and Recording Details modal. Used JavaScript and React to implement these changes, focusing on API integration and frontend development. Improved test coverage by updating getShowVideoUrl tests to verify correct application of output settings, which increased resilience and reliability. Tracked all changes through detailed commit history to align with product goals for consistent media rendering.
