This paper is structured as a technical brief suitable for developers integrating advanced playback capabilities into KMP applications (Android/iOS/Desktop). 1. Introduction Kotlin Multiplatform (KMP) allows sharing business logic across Android, iOS, and Desktop JVM targets. However, media playback with support for proprietary or less common codecs (e.g., E-AC-3, DTS, RV40, some MPEG-4 variants) remains a challenge because native platform players (ExoPlayer, AVFoundation, MediaPlayer) rely on system codecs. However, media playback with support for proprietary or
