Whether the VideoPlayer has successfully prepared the content to be played. (Read Only)
A prepared VideoPlayer can start playing back the associated content instantly, as opposed to the normal delay incurred by starting playback from scratch, which involves acquiring the playback resources and pre-loading some or all of the content.
A VideoPlayer starts out as not prepared (false) and becomes prepared (true) once VideoPlayer.Prepare has been invoked and the VideoPlayer.prepareCompleted event has been emitted. The property goes back to false when VideoPlayer.Stop is invoked.
Preparation failures may lead to this property never becoming true. In this case an error description will be sent through the VideoPlayer.errorReceived event.
