VdoPlayer

An instance of this class is created for every video embedded into the page. This class initializes the playback. it also exposes a set of utility methods and properties to provide a common js api interface for all vdocipher videos.

This class creates an iframe inside the container element. The iframe loads an internal player based on device capabilities. This class maintains a sync between the internal player properties. It exposes a common set of properties, methods and events irrespective of underlying player or device.

The properties are updated based on underlying player events and relies on async postMessage actions. Hence, there can be delay (~200ms).

• All properties are read-only
• Directly created instances of this class will not be accessible from the vdo.getObjects() method.
