Chenxuan developed a new Mixch Movie extractor for the harry0703/yt-dlp repository, expanding the tool’s ability to access and download content from mixch.tv/m/ URLs. Using Python, Chenxuan implemented URL matching, extraction of video metadata such as title and uploader, and integrated comprehensive tests to ensure reliability. The work included standardizing URL handling by removing redundant 'www.' prefixes, which reduced edge-case failures and improved maintainability. Focusing on API integration and web scraping, Chenxuan’s contributions laid a foundation for broader Mixch source support, demonstrating a methodical approach to feature development and code quality within a short, focused development period.
