AVPlayer Class

Definition

Encapsulates the control and UI of a component that plays back single or multiple items.

[Foundation.Register("AVPlayer", true)]
[ObjCRuntime.Unavailable(ObjCRuntime.PlatformName.WatchOS, ObjCRuntime.PlatformArchitecture.All, null)]
public class AVPlayer : Foundation.NSObject
type AVPlayer = class
    inherit NSObject
Inheritance

Derived
Attributes

Remarks

An AVPlayer links the visual presentation, control, and dynamic state of one or more AVAssets.

The visual element of the display is done by a AVPlayerLayer, while it's current state (current time, etc.) is held in an AVPlayerItem, which in turn references an AVAsset.

var asset = AVAsset.FromUrl(NSUrl.FromFilename("sample.m4v"));
var playerItem = new AVPlayerItem(asset);
var player = new AVPlayer(playerItem);
var playerLayer = AVPlayerLayer.FromPlayer(player);
View.Layer.AddSublayer(playerLayer);
player.Play();

Constructors
