ExoPlayer
ExoPlayer is an open-source, application-level media player library for Android that provides an alternative to Android's MediaPlayer API. It supports features like DASH, SmoothStreaming, HLS, and advanced customization for audio and video playback. It is designed to be highly extensible and efficient, making it suitable for demanding media applications.
Developers should use ExoPlayer when building Android apps that require robust media playback with support for modern streaming protocols (e.g., DASH, HLS) or need custom playback features like adaptive bitrate streaming. It is ideal for video streaming apps, music players, or any application where performance and flexibility in media handling are critical, as it offers better control and fewer limitations compared to the default MediaPlayer.
