Nuwan worked on the rdkcentral/aamp repository, delivering features and fixes that enhanced streaming reliability, playback accuracy, and memory management. He implemented independent DASH track downloads and refactored ABR logic for safer bandwidth estimation, using C++ and GStreamer to improve buffer handling and concurrency control. His work addressed complex scenarios such as multi-key DRM fallback, low latency streaming, and robust ad transitions, with targeted debugging and unit testing to ensure stability. By integrating new buffer managers and refining pipeline synchronization, Nuwan improved end-to-end playback quality and reduced crash risk, demonstrating depth in system programming and streaming protocol optimization throughout the codebase.

Oct 1, 2025Concise monthly summary for 2025-10 focused on the AAMP repository (rdkcentral/aamp). The month was dominated by enhancements to PTO-aware playback to improve timing accuracy and delivery of PTS restamping under Presentation Time Offset conditions. The primary outcome is a robust pipeline flush mechanism that ensures PTS restamping remains correct when PTO is present, with minimal impact on other streams.

Jul 1, 2025July 2025: Stability-focused bug fix for AAMP's LLD playback rate corrections in rdkcentral/aamp. Replaced time comparisons from SYSTEM clock to STEADY clock to prevent incorrect rate adjustments due to time discrepancies, resulting in more accurate live latency calculations. This directly supports reliable streaming on low-latency channels and aligns with VPLAY-10265 (#286).
