Work with MediaPlayer objects

The PTMediaPlayer object represents your media player and a PTMediaPlayerItem represents audio or video on your player.

About the MediaPlayerItem class
Successfully loading a media resource creates an instance of the PTMediaPlayerItem class.
Lifecycle and states of the MediaPlayer object
From the moment when the PTMediaPlayer instance is created to the moment it is terminated (reused or removed), the PTMediaPlayer object completes a series of transitions from one status to another.
