Nov 1, 20252025-11: Intel/media-driver — Codebase reorganization to improve maintainability and onboarding. Reorganized the media-driver component structure by moving ULT files to the media softlet directory, aligning with the PDVT-SH/Media Common structure. This groundwork reduces navigation time, clarifies ownership of media components, and enables faster future feature work and testing. No major bugs fixed in this period. This work reduces maintenance friction and establishes a scalable foundation for future feature work and reliability.
