ExoPlayer

Google’s open source media player library for Android, built on low-level MediaCodec APIs for high-performance streaming.

ExoPlayer replaces the standard Android MediaPlayer with a modular framework designed for scale. It supports advanced features like DASH, SmoothStreaming, and HLS playback, while handling complex DRM requirements through Widevine. Developers get granular control over buffering strategies and multi-track selection (audio, video, and subtitles). Because it is a library included in the APK, updates are independent of Android OS versions, ensuring consistent behavior across 2.5 billion active devices.
