During January 2025, Harry contributed to the harry0703/yt-dlp repository by enhancing Bluesky video metadata extraction. He focused on improving data quality by updating the extractor to prefer the source video format, which reduced ambiguity in format selection. Using Python and leveraging skills in API integration and web scraping, Harry fixed issues with MD5 hashes and uploader information for specific Bluesky posts, resulting in more accurate metadata. He also added support for chapters and heatmap fields, enriching the extracted video data for better indexing and analytics. The work demonstrated a targeted, in-depth approach to feature development within a specialized domain.
