Shaka Player is an open-source JavaScript library for adaptive playback in the browser, built directly on MSE and EME. It supports both DASH and HLS, multi-DRM via EME, offline storage, low-latency streaming, and captions - a full-featured engine maintained by Google.

It is one of the standard choices for web playback alongside hls.js, dash.js, and Video.js. Teams pick a web player based on protocol and DRM needs, ecosystem fit, and how much they want to customize; Shaka is favored for robust multi-DRM DASH support and a clean, well-documented API, and is also used as the playback core inside some smart-TV apps.
