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
| AVPlayer() |
