IMAContentPlayhead
@protocol IMAContentPlayhead
Defines an interface for a class that tracks video content progress and
exposes a key value observable property |currentTime|.
The SDK provides an implementation for tracking AVPlayer-based playback
in the IMAAVPlayerContentPlayhead.
Publishers can supply their own implementation by implementing this
interface and this way support any other video playback implementation
they might have.
-
Reflects the current playback time in seconds for the content.
The property is key value observable.
Declaration
Swift
var currentTime: TimeInterval { get }
Objective-C
@property (nonatomic, readonly) NSTimeInterval currentTime;
