NSURL *url = [NSURL URLWithString:@"http://1080Digital.stream/playlist.m3u8"];

mp = [[MPMoviePlayerViewController alloc]initWithContentURL:url];

if(mp.moviePlayer.playbackState == MPMoviePlaybackStateInterrupted || mp.moviePlayer.playbackState == MPMoviePlaybackStateStopped || mp.moviePlayer.playbackState == MPMoviePlaybackStatePaused)

    [mp.moviePlayer play];

}

[[mp moviePlayer] pause];

[mp.view removeFromSuperview];

[[mp moviePlayer] play];

}
