Interface DrmControllerEventMap

A DRM error occurred.

The status of a key session's keys changed, e.g. a key became usable after a license was applied, or expired / output-restricted.

A license exchange completed. The span is attributed at the source to the track that initiated the license request (via the key session that produced the message), so concurrent exchanges for the active and a preloaded track do not cross-attribute. The player republishes it as loadSpan using the carried trackUri.

The media keys have been created and set.

This will happen after the first call to initialize or after the first 'encrypted' event is handled.

Emitted when the error state has been reset.

Dispatched after a key session has been closed.

Dispatched after a key session has been created.
