Instance Members

sessionId: String

Contains a unique string generated by the CDM for the current media object and its associated keys or licenses.

expiration: Float

The time after which the keys in the current session can no longer be used to decrypt media data, or NaN if no such time exists. This value is determined by the CDM and measured in milliseconds since January 1, 1970, UTC. This value may change during a session lifetime, such as when an action triggers the start of a window.

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 Closing a session means that licenses and keys associated with it are no longer valid for decrypting media data.

keyStatuses: MediaKeyStatusMap

Contains a reference to a read-only MediaKeyStatusMap of the current session's keys and their statuses.

onkeystatuseschange: haxe.Function

Sets the EventHandler called when there has been a change in the keys in a session or their statuses.

onmessage: haxe.Function

Sets the EventHandler called when the content decryption module has generated a message for the session.
