首先使用AVPlayer 必须导入框架：AVFoundation 以及 头文件：#<MediaPlayer/MediaPlayer.h>

两者的主要区别在路径的初始化：

1、播放本地视频

 NSURL *sourceMovieUrl = [NSURL fileURLWithPath:@"本地视频路径"];

    AVAsset *movieAsset = [AVURLAsset URLAssetWithURL:sourceMovieUrl options:nil];

    AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:movieAsset];

    _myPlayerItem1 = playerItem;

    _player1 = [AVPlayer playerWithPlayerItem:playerItem];

    _playerLayer1 = [AVPlayerLayer playerLayerWithPlayer:_player1];

    _playerLayer1.frame = CGRectMake(0, 0, 1024, 600);

   _playerLayer1.videoGravity =AVLayerVideoGravityResizeAspect;

    [self.view.layer addSublayer:_playerLayer1];

     [_player1 play];
