Powerful Cross‑Format Local Media Player

M‑Player is a UWP media player built on FFmpegInteropX, designed for Windows (desktop and Xbox). It plays the vast majority of common and niche video/audio formats and supports external subtitles, playlist management, automatic resume of playback position, and screenshot capture. The app balances a refined desktop experience with TV/controller usability, and supports Picture-in-Picture (CompactOverlay) and system media controls.
