Then begin to familiarize yourself with the XBMC source code, maybe start by looking how tag reading is implemented for music files.
PS! Please keep in mind that XBMC is a cross-platform application
Quote:Try to make all code, feature, and functions to be platform agnostic - XBMC is a multi-platform software, thus any single platform specific features should be discussed with other team members before implemented. Major features should be developed in a separate branch or committed in small increments so that other members have the opportunity to review the code and comment on it during development.Best would be to use a cross-platform library so that the same function/feature can be implemented the same on all platforms that XBMC runs on, or at the very least on XBMC for Linux, Mac, and Windows.
