HTMLMediaElement: setMediaKeys() method

Secure context

The setMediaKeys() method of the HTMLMediaElement interface sets the MediaKeys that will be used to decrypt media during playback.

It returns a Promise that fulfils if the new keys are successfully set, or rejects if keys cannot be set.

Syntax

setMediaKeys(mediaKeys)

Parameters

• mediaKeys
  • : A MediaKeys object that the HTMLMediaElement can use for decryption of media data during playback.

Return value

A Promise that fulfills with undefined.

Exceptions

The returned promise may reject an error:

• InvalidStateError DOMException
  • : Media keys are already in the process of being attached, or the previous keys cannot be removed at the current time (for example, because the particular implementation does not allow removal during playback).
• QuotaExceededError
  • : The passed keys are already in use by another element, or the browser is unable to use it with this element for other reasons.
• NotSupportedError DOMException
  • : The media keys that are currently associated with the media cannot be disassociated, because this is not supported by either the CDM or the browser.
