# Tracks Store | Consideration | Status | | ----------------------- | ------------------------- | | Preferred import style | No enforced import style | | Multithread environment | Always run in main thread | ## Overview The "Tracks Store" module is written specifically to facilitate the choosing of a specific Adaptation/track and Representations/qualities through the RxPlayer API. The job of this module is to provide a simple API with few methods allowing to choose based on IDs while it takes care of the specificities and technical details behind the curtains. ## `TracksStore` `TracksStore` is the main implementation used for Manifest-based contents. It centralizes the currently chosen tracks and qualities and exposes simple operations for the API to switch them. ## `TrackDispatcher` `TrackDispatcher` links track decisions to the underlying streaming logic for a given type. It is responsible for propagating updated choices and constraints when the selected track or representations change. ## `MediaElementTracksStore` `MediaElementTracksStore` is the directfile-oriented counterpart. It relies on the media element's native track APIs (`audioTracks`, `videoTracks`, `textTracks`) instead of the Manifest-based track model used by `TracksStore`.
