Media Session API: Presenting slides actions

Category

Multimedia

Type

Chromium catches up

Status

Enabled by default (Chrome 111)

Intent stage

Shipped

Summary

Adds "previousslide" and "nextslide" actions to the existing Media Session API.

Motivation

This will enable developers of video conferencing websites to handle these actions from browser UI. For example, if the user puts their slides presentation into a picture-in-picture window, the browser could display buttons for navigating through slides. When the user clicks those, the website handles them through the Media Session API.

Standards & signals

• Specification: https://w3c.github.io/mediasession/#dom-mediasessionaction-previousslide
• Firefox: No signal
• Safari: No signal
• Web developers: Positive — The existence of the popular (100K+ users) Remote for Slides extension (https://chrome.google.com/webstore/detail/remote-for-slides/pojijacppbhikhkmegdoechbfiiibppi) proves that there is strong user demand for a (remote) slide control feature, up to the point that they would install an extension just for that.
