iOS AVPlayer won't play

I have the following code set up to play a video in my iOS app, but it just doesn't play. The app compiles and runs, but all I get a red frame where I positioned it. When debugging, I found that the the program doesn't even step into the last line [player play]. Also, the video runs fine in a UIWebView.

NSString *streamingString = [NSString stringWithFormat:@"http://youtu.be/...."];

AVAsset *asset = [AVAsset assetWithURL:[NSURL URLWithString:streamingString]];
AVPlayerItem *playerItem = [[AVPlayerItem alloc] initWithAsset:asset];
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];
AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:player];

[layer setPlayer:player];

[layer setFrame:CGRectMake(50, 50, 400, 300)];
[layer setBackgroundColor:[UIColor redColor].CGColor];
[layer setVideoGravity:AVLayerVideoGravityResizeAspectFill];

[self.view.layer addSublayer:layer];

[player play];

I am a new programmer and this is my first post to Stackoverflow, so please excuse me if I have not given enough information or am missing something obvious! Thank you so much!

assetWithURL: is often, but not always, used with a URL that points to a file already on the device, often within the bundle. If you are using an external URL, such as one on the internet, the url must resolve to a video that is in a format that the AVPlayer can understand. A URL to a YouTube web page will not work. In general, you can't play a YouTube video in AVPlayer.

Check out this document from Apple and this video on YouTube.

EDIT:

Some developers have used this library to play a YouTube video in their app. Another option is to use a UIWebView.
