MediaKeySession: closed property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2019.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The closed read-only property of the MediaKeySession interface returns a Promise signaling when a MediaKeySession closes. This promise can only be fulfilled and is never rejected. Closing a session means that licenses and keys associated with it are no longer valid for decrypting media data.

Value

A Promise.
