is it possible to read metadata using HTTP live streaming in the iPhone SDK

Question

When playing a live stream using the HTTP Live Streaming method, is it possible read the current metadata (eg. Title and Artist)? This is for an iPhone radio app.

Answer 1

in swift 2.0 getting metadata info music streaming:

PlayerItem.addObserver(self, forKeyPath: "timedMetadata", options: NSKeyValueObservingOptions.New, context: nil)

add this method:

override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer) {

    //Atualiza Nome Musica
    if keyPath == "timedMetadata" {
        if let meta = PlayerItem.timedMetadata {
            print("Novo Metadata \(meta)")
            for metadata in meta {
                if let nomemusica = metadata.valueForKey("value") as? String{
                    LB_NomeMusica.text = nomemusica
                    if NSClassFromString("MPNowPlayingInfoCenter") != nil {
                        let image:UIImage = UIImage(named: "logo.gif")!
                        let albumArt = MPMediaItemArtwork(image: image)
                        var songInfo: [String:AnyObject] = [
                            MPMediaItemPropertyTitle: nomemusica,
                            MPMediaItemPropertyArtist: "Ao Vivo",
                            MPMediaItemPropertyArtwork: albumArt
                        ]
                        MPNowPlayingInfoCenter.defaultCenter().nowPlayingInfo = songInfo
                    }
                }
            }
        }
    }
