During March 2026, this developer enhanced the hanxi/xiaomusic repository by building robust streaming proxy features for Xiaomi LX06 and Bilibili integration. They implemented a token-based URL shortening system with in-memory caching using Python and JavaScript, enabling shorter proxy URLs and supporting multiple requests per track. Their work included refactoring the token cache for maintainability and improving backend diagnostics. By generalizing FFmpeg streaming with async programming and adding playlist support, they increased playback reliability and reduced CDN-related errors. These backend and frontend improvements addressed playback failures on low-end devices, streamlined playlist usage, and provided clearer diagnostics for ongoing support and maintenance.

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.
