PROFILE
Philipp Hancke
During January 2025, Phancke enhanced the libsdl-org/aom repository by implementing a per-frame PSNR calculation feature for video encoding workflows. This addition introduced a new flag, AOM_EFLAG_CALCULATE_PSNR, enabling per-frame quality metrics when g_lag_in_frames is set to zero. Phancke used C and C++ to integrate the feature, focusing on codec development and performance metrics. Comprehensive tests were developed to validate both the functionality and its limitations, ensuring robust quality assurance and preventing regressions. This work provided encoder developers with granular, data-driven insights for tuning, advancing the library’s testing infrastructure and supporting improved video encoding quality assessment.

1 Commits • 1 Features
Jan 1, 2025Month: 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.
