Cosmin contributed to the FFmpeg/FFmpeg repository by updating the DoVi Level 11 metadata alignment and parsing logic. Focusing on C programming and metadata management, Cosmin restructured the AVDOVIDmLevel11 fields to match current DoVi specifications, addressing deprecated definitions and improving the accuracy of metadata encoding and decoding. The work involved refining both the avutil/dovi_meta and avcodec/dovi_rpu modules to ensure correct parsing and writing of Level 11 metadata, which reduces interoperability risks across different playback environments. This targeted feature development demonstrates a strong grasp of video processing and software development, delivering deeper standards compliance for future DoVi specification updates.
