January 2026: FFmpeg/FFmpeg focused on reliability and compatibility in the SVT-AV1 encoding path. Implemented a targeted bug fix to align SVT-AV1 encoder configuration with version 4.0.0 requirements by renaming the adaptive quantization mode parameter (aq_mode). This prevents encoder misconfiguration and stabilizes upgrades. The change (commit a5d4c398b411a00ac09d8fe3b66117222323844c) reduces support tickets and preserves compatibility in the libsvtav1 path. This work demonstrates solid C/C++, encoder framework knowledge, and version-aware configuration discipline, delivering clear business value through more reliable media encoding pipelines.

April 2025 mpv-work monthly summary: Delivered a targeted build-system hardening fix in mpv-player/mpv to stabilize Windows builds by correcting the DXGI/D3D11 build check placement. The check now executes after including video/out/gpu/d3d11_helpers.c, ensuring dependent builds are evaluated in the correct context. This prevents EGL-Angle-Win32 from being enabled without D3D11 active, reducing inconsistent build behavior and CI flakiness. The change is traceable via commit b3070d1255c461871db2e66918cab225512ea38f. Overall impact includes improved reliability for Windows builds and better downstream compatibility across configurations.
