MediaKeyMessageEvent: MediaKeyMessageEvent() constructor

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 MediaKeyMessageEvent constructor creates a new MediaKeyMessageEvent object.

new MediaKeyMessageEvent(type)
new MediaKeyMessageEvent(type, options)

A string with the name of the event. It is case-sensitive and browsers always set it to message.

An object that, in addition of the properties defined in Event(), can have the following properties:

messageType: A message type that allows applications to differentiate messages without parsing them. Allowed values are: license-request, license-renewal, license-renewal, or individualization-request.
message: An array containing the message generated by the content decryption module.
