+**Compose Media Player** is a video player library designed for Compose Multiplatform, supporting multiple platforms including Android, macOS, Windows, and Linux. It is the first fully functional multiplatform video player for Compose for Desktop that requires no additional software installations. All desktop platforms communicate with their native backends through **pure JNI** — no JNA, no GStreamer Java bindings, no external runtime dependencies. The library leverages:
 
-- **GStreamer** for Linux
-- **Media Foundation** for Windows
-- **AVPlayer** for macOS and iOS
