keyStatuses

val keyStatuses: MediaKeyStatusMap

The keyStatuses read-only property of the MediaKeySession interface returns a reference to a read-only MediaKeyStatusMap of the current session's keys and their statuses.

keyStatusesChangeEvent

val MediaKeySession.keyStatusesChangeEvent: EventInstance<Event, MediaKeySession, MediaKeySession>

messageEvent

val MediaKeySession.messageEvent: EventInstance<MediaKeyMessageEvent, MediaKeySession, MediaKeySession>

MDN Reference

onkeystatuseschange

var onkeystatuseschange: EventHandler<Event, MediaKeySession, MediaKeySession>?

MDN Reference

onmessage

MDN Reference

sessionId

val sessionId: String

The sessionId read-only property of the MediaKeySession interface contains a unique string generated by the content decryption module (CDM) for the current media object and its associated keys or licenses.

Functions

suspend fun close()

The close() method of the MediaKeySession interface notifies that the current media session is no longer needed, and that the content decryption module should release any resources associated with this object and close it.

closeAsync

fun closeAsync(): Promise<Void>

dispatchEvent

fun dispatchEvent(event: Event): Boolean

generateRequest

suspend fun generateRequest(initDataType: String, initData: BufferSource)

The generateRequest() method of the MediaKeySession interface returns a Promise after generating a license request based on initialization data.

generateRequestAsync

fun generateRequestAsync(initDataType: String, initData: BufferSource): Promise<Void>

load

suspend fun load(sessionId: String): Boolean

The load() method of the MediaKeySession interface returns a Promise that resolves to a boolean value after loading data for a specified session object.

loadAsync

fun loadAsync(sessionId: String): Promise<JsBoolean>

remove

suspend fun remove()

The remove() method of the MediaKeySession interface returns a Promise after removing any session data associated with the current object.

removeAsync

fun removeAsync(): Promise<Void>

update

suspend fun update(response: BufferSource)

The update() method of the MediaKeySession interface loads messages and licenses to the CDM, and then returns a Promise.

updateAsync

fun updateAsync(response: BufferSource): Promise<Void>

when

fun <T : Event> when(type: EventType<T>, options: ObservableEventListenerOptions?): Observable<T>
