During this period, work centered on enhancing the aom library by implementing a per-frame PSNR calculation feature for video encoding. This addition introduced a new flag, AOM_EFLAG_CALCULATE_PSNR, enabling per-frame quality metrics when g_lag_in_frames is set to zero. The approach involved careful integration in C and C++, with comprehensive tests developed to validate both the feature’s functionality and its operational boundaries. All changes were contributed to the libsdl-org/aom repository, with a focus on maintaining code quality and robust test coverage. This work advanced codec development and performance metrics, supporting more granular encoder quality assurance and data-driven tuning.

Month: 2025-01. This period focused on delivering a quantitative quality metric enhancement in the aom library (libsdl-org/aom) by introducing per-frame PSNR calculation for video encoding. The feature enables per-frame PSNR reporting when encoding, gated by g_lag_in_frames == 0, and adds tests to validate functionality and its limitations. No major defects recorded this month; resources were allocated to ensure robust test coverage and flag-based capability control. The work advances quality assurance capabilities and provides data-driven insight for encoder tuning, contributing to improved customer value and product quality.
