Investigation and Resolution of Android Audio Playback Noise Issue in HLS Streams

The Android app’s HLS video produced an electric‑like noise because FFmpeg’s av_find_best_stream mistakenly selected the second audio track in a dual‑stream file, a track lacking 1‑8 kHz frequencies, whereas iOS and PC used the correct first track; fixing requires publishing videos with a single audio track and adding detection tools.

Analysis and Solutions for a Memory Leak Caused by a Repeating Animation in iOS

The article explains how a repeating iOS animation caused a hidden memory leak by retaining its view controller through a strong CABasicAnimation delegate and a performSelector‑afterDelay timer, and shows how replacing the delegate‑based animation with a CAKeyframeAnimation/CAAnimationGroup and using weak references or cancelling pending selectors eliminates the retain cycle.

Optimizing Vue/Vuetify Projects with Webpack: Code Splitting, CommonsChunkPlugin, and Externals

By using Webpack’s CommonsChunkPlugin to extract node_modules into a vendor chunk, configuring externals to load Vue and Vuetify from a CDN, and converting non‑critical components to async imports, a Vuetify‑based app reduces its first‑screen bundle by hundreds of kilobytes, improves caching, and speeds initial load.

Generating Long Event Images for QQ Music Albums: Front‑end and Server‑side Solutions, Pitfalls and Optimizations

To quickly create shareable long‑event images for QQ Music albums, the team evaluated client‑side DOM‑to‑image tools (html2canvas and SVG) that suffered from blur, incompleteness, slow rendering and oversized base64 data, then migrated rendering to the server using PhantomJS, node‑canvas and ultimately ImageMagick, whose combined script execution, mpc caching, and Q8 build provided the most balanced quality‑performance solution despite remaining operational quirks.
