MediaInfo is a mature, cross-platform application for extracting and displaying technical and tag metadata from audio and video files. It provides a command-line interface (CLI) and multiple graphical front-ends (Qt, wxWidgets, Cocoa, VCL, UWP, Android, iOS) all sharing a common core library (MediaInfoLib). The repository contains the full source for the CLI, all GUIs, Windows shell extension, installers, and build/packaging scripts. The architecture is a classic layered design: a central Core class wraps MediaInfoLib and is consumed by each GUI via platform-specific adapters. The codebase is functional and widely used, but suffers from significant fragmentation across GUI frameworks and build systems, with legacy components (VCL, UWP) and conditional compilation adding maintenance overhead. The translation system using CSV files is well-designed and the command-line parser is robust, but most components are tightly coupled to the MediaInfo domain and not easily reusable outside the project.
