Media Source Extensions

Media Source Extensions (MSE) is a W3C specification that allows JavaScript to send byte streams to media codecs within web browsers that support HTML video and audio. Among other possible uses, this allows the implementation of client-side prefetching and buffering code for streaming media entirely in JavaScript. It is compatible with, but should not be confused with, the Encrypted Media Extensions (EME) specification, and neither requires the use of the other, although many EME implementations are only capable of decrypting media data provided via MSE.

Browser support

The Media Source Extensions API is widely supported across all modern web browsers, with the only exception being iPhone-family devices (although it is supported on iPadOS). Firefox 37 already had a subset of MSE API available for use with only YouTube in Firefox 37 on Windows Vista or later only, while Mac OS X version had in enabled starting version 38.
