Developed streaming proxy enhancements in the hanxi/xiaomusic repository to improve playback reliability for Xiaomi LX06 devices and Bilibili CDN streams. Leveraged Python and JavaScript to implement a token-based URL shortening system with in-memory caching, reducing proxy URL length and supporting multiple requests per track. Refactored the token cache for maintainability and integrated async programming techniques for efficient streaming. Enhanced backend logic to support Bilibili playlists, introduced precise CDN domain suffix checks, and generalized FFmpeg streaming with content-type fallbacks. These changes reduced playback failures, stabilized streaming across CDNs, and provided clearer diagnostics, resulting in smoother playlist usage and lower support overhead.

March 2026: Delivered critical streaming proxy enhancements for Xiaomi LX06 compatibility and Bilibili CDN reliability, delivering tangible business value by reducing playback failures and expanding playlist support. Implemented a token-based Xiaomi proxy URL shortening with in-memory caching, enabling ~60-character proxy URLs and preserving multiple requests per track. Refactored the token cache for maintainability. Strengthened Bilibili proxy routing with precise CDN domain suffix checks, generalized FFmpeg streaming with extra headers, and content-type fallbacks, plus new Bilibili playlist support. Enabled on-the-wire testing and diagnostics to reduce support overhead. Also improved resilience against CDN access errors by streaming via FFmpeg to MP3, lowering 403-related playback failures on LX06. Overall impact: higher playback reliability on low-end devices, smoother playlist usage, and clearer backend diagnostics.
