Public account of Tencent Music's development team, focusing on technology sharing and communication.
The team accelerated the QMusic live‑streaming SDK by converting large source modules and external pods into pre‑compiled binaries, tuning Xcode build settings, and automating CI caching, slashing full‑build times from roughly 400 seconds to 40 seconds and packaging duration from over 50 minutes to three minutes.
The team built a low‑intrusion Gradle plugin that detects changed source and resource files, performs precise dependency analysis, leverages aapt2 for incremental resource compilation, and injects updated Dex and assets into the running app, cutting full Android builds from 418 seconds to 13 seconds and boosting daily developer productivity on large projects such as QQ Music.
At INTERSPEECH 2020 the authors introduced a phase‑aware music super‑resolution system that uses a frequency‑domain GAN combined with an enhanced Griffin‑Lim algorithm to reconstruct missing high‑frequency magnitude and phase, delivering brighter, louder, and more natural‑sounding recordings that surpass traditional interpolation and naive phase‑flipping methods.
Pigeon lets Flutter developers define a single Dart API that automatically generates matching, type‑safe interface code for Android and iOS, eliminating manual method‑channel boilerplate, preventing naming mismatches, and keeping native and Dart implementations synchronized across platforms.
The article describes how a live‑room video‑gift feature originally built for mobile was ported to a web client by extracting separate color and alpha video streams, compositing them on canvas, then migrating the per‑pixel blending to WebGL shaders, which cut CPU usage dramatically, raise frame rates to about 60 FPS, and outline further optimisations such as pre‑loading, mobile support, and possible MSE or WebAssembly approaches.
Browser caching works by storing copies of web resources in memory, disk, or service‑worker caches and using HTTP headers such as Cache‑Control, Expires, ETag, and Last‑Modified to decide freshness, allowing strong (local) and negotiated (weak) cache stages, while developers can fine‑tune performance with CDN settings, IndexedDB, Service Workers, and HTML5 storage to create optimal, auditable cache strategies.
By migrating the “全民 K 歌” base library to a monorepo using Lerna, Yarn workspaces, and TypeScript, the team unified dependency management, enabled topological builds, enforced master‑only versioning with conventional commits, and automated CI‑driven publishing—including beta canary releases—significantly speeding iteration and improving maintenance.
To meet the post‑COVID surge in K‑song live broadcasts, the team replaced high‑latency HLS with low‑latency HTTP‑FLV and built the cross‑platform kg‑player SDK—combining MSE, WASM, and WebGL decoding—to automatically adapt streams, reduce stutter, and support iOS/Android, improving performance and powering hundreds of thousands of daily views.
The article explains Flutter’s three‑layer architecture and rendering pipeline, compares web‑container, generic‑container, and self‑draw engine cross‑platform approaches, details unified and three‑side hybrid integration patterns with navigation scenarios, evaluates hybrid frameworks, and discusses compilation modes, artifact integration, and engineering workflow for hybrid projects.
The article thoroughly examines Lottie animation technology, describing how After Effects projects are converted into JSON, parsed into Objective‑C data models such as LOTComposition and LOTLayer, and rendered on iOS/Android via Core Animation, detailing asset handling, layer hierarchy, frame interpolation, and implementation specifics.
