Worked on the iptv-org/iptv repository to enhance playlist reliability by addressing a specific data integrity issue. Focused on stream management and data handling, the developer identified and removed all unresponsive streaming entries from the es_45.95.78.m3u playlist, ensuring that only valid streams remained available to users and downstream pipelines. This targeted bug fix, implemented in plaintext, improved the overall hygiene of the IPTV catalog and reduced the risk of errors caused by invalid entries. The approach demonstrated careful change management, with clear commit documentation and traceability, ultimately contributing to a more stable and efficient streaming experience for end users.
