Navigator: mediaSession property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.
The mediaSession read-only property of the Navigator
interface returns a MediaSession
object that can be used to share with the browser metadata and other information about
the current playback state of media being handled by a document.
This information may, in turn, be shared with the device and/or operating system in order to a device's standard media control user experience to describe and control the playback of the media.
In addition, the MediaSession interface provides the
setActionHandler() method, which lets
you receive events when the user engages device controls such as either onscreen or
physical play, pause, seek, and other similar controls. An internet radio app, for
example, can use setActionHandler() to let the media controls on a keyboard
or elsewhere on the user's device be used to control the app's media playback.
Value
A MediaSession object the current document can use to share information
about media it's playing and its current playback status. This information can include
typical metadata such as the title, artist, and album name of the song being played as
well as potentially one or more images containing things like album art, artist photos,
and so forth.
Examples
In this example, metadata is submitted to the mediaSession object. Note
that the code begins by ensuring that the navigator.mediaSession property
is available before attempting to use it.
if ("mediaSession" in navigator) {
navigator.mediaSession.metadata = new MediaMetadata({
title: "Podcast Episode Title",
artist: "Podcast Host",
album: "Podcast Name",
artwork: [{ src: "podcast.jpg" }],
});
}
