public void realize()
Constructs the media dependent portions of the Controller. This may include examining media data and might take some time to complete.
The realize method puts the Controller into the Realizing state and returns immediately. When realize is complete and the Controller is in the Realized state, the Controller posts a RealizeCompleteEvent.这里面红色标注的post是啥意思?它对realize这个函数有什么意义?
