Media Source Extensions (MSE) is a W3C specification that extends HTML5 video and audio elements to allow dynamic manipulation of media content. MSE allows JavaScript to send video and audio data directly to a media player, bypassing the need for a traditional server-side container format. This enables a wider range of media applications and use cases, such as adaptive streaming, live streaming, and custom media pipelines.
MSE works by allowing the web developer to create a MediaSource object in JavaScript, which can then be attached to a media element (such as a video or audio tag) as its source. The developer can then use JavaScript to generate and send media data to the MediaSource object, which is then passed on to the media player for playback.
MSE is widely supported by modern web browsers, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and others. It is an important technology for building advanced media applications on the web and is used by many popular streaming services.
