Media slot

The key insight with Media Chrome is separating the UI from the media playback. Media Chrome is agnostic to whatever playback engine you are using to play your media. Media Chrome is purely about building the UI.

Media Chrome uses the media slot specified with slot="media" in order to interact with the media. For example, when a viewer clicks the “play” button, Media Chrome will call play() on whatever element is specified in the media slot.

Media Slot

The simplest media slot is the browser’s native <video> tag. For example:

  <video slot="media" src="https://....mp4" >

In this example, Media controller will:

  • Listen for events emitted from the <video> element
  • Understand the current state of the <video> element by using the known props
  • Call methods on the <video> element like play(), pause(), etc.

The superpower of Media Chrome is that the media slot does not have to be a <video> element. It can be any HTML element that implements the HTML5 Video Element API. See the list of Media Elements below for examples of compatible elements that can be used with slot="media".

Media Elements

All of these elements are web components that can be used as slot="media" because they mirror the HTML5 video element API. Note that all of these media elements are responsible solely for playing the media, they don’t implement any UI controls.
