Specification
Core specification: https://w3c.github.io/mediasession/Summary
Adds an 'enterpictureinpicture' action to the Media Session API. Websites can register an action handler which can be used to open a Picture-in-Picture or Document Picture-in-Picture window.
Blink component
Blink>Media>Session
Motivation
While in theory UAs can detect playing videos and offer UI to automatically put that video into picture-in-picture without the website’s involvement, delegating a Media Session action to the website instead allows the website to either create a canvas-backed video picture-in-picture experience on the fly or create a more feature-rich document picture-in-picture experience.
