Getting Metadata from Shoutcast stream Android

Question

I am developing a Radio App for Android devices that is supposed to get streaming from a Shoutcast Server.

The sound is working fine but I want to retrieve the MetaData as well so I might be able to show the currently played song's Title, artist, as well as the Album Picture.

I used the MediaMetaDataRetriever but it doesn't seem to be working at all!

This is the code I used:

public class MainActivity extends FragmentActivity {

private ImageView bannerView;
private int[] pub = {R.drawable.banner, R.drawable.pubnautic, R.drawable.pubquad};
private int i = 0;

private ImageView play;
private ImageView pause;
private TextView title;
private MediaPlayer mediaPlayer;
private MediaMetadataRetriever retriever;
private String out;
private String url = "http://streamplus8.leonex.de:14910";

private ImageView albumpic; 
private byte[] image;
private boolean paused = false;

private ImageView exit;

private ImageView wish;

private ImageView reservation;

private ImageView contact;

private ImageView facebook;

private ImageView twitter;

@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    bannerView = (ImageView) findViewById(R.id.banner);

    play = (ImageView) findViewById(R.id.play);
    pause = (ImageView) findViewById(R.id.pause);
    exit = (ImageView) findViewById(R.id.exit);
    albumpic = (ImageView) findViewById(R.id.artist);
    title = (TextView) findViewById(R.id.title);
    retriever = new MediaMetadataRetriever();
    mediaPlayer = new MediaPlayer();

    wish = (ImageView) findViewById(R.id.wish);

    reservation = (ImageView) findViewById(R.id.shop);

    contact = (ImageView) findViewById(R.id.contact);

    facebook = (ImageView) findViewById(R.id.facebook);

    twitter = (ImageView) findViewById(R.id.twitter);

    this.setVolumeControlStream(AudioManager.STREAM_MUSIC);  

    try {
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        mediaPlayer.setDataSource(url);
        retriever.setDataSource(url);
        mediaPlayer.prepareAsync();
    } catch (Exception e) {
        Toast.makeText(getApplicationContext(), "Please check your connection!", Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }

    play.setOnClickListener(new OnClickListener() {

        @Override

                            mediaPlayer.start();

                        }
                    });
                }

Thanks for your help!

Answer 1

I created my own class to retrieve the metadata based on a modified version of streamscraper. Use this jar (streamscraper), this jar (jsoup) and this class to retrieve the metadata. The interface is similar to MediaMetadataRetriever:

ShoutCastMetadataRetriever smr = new ShoutCastMetadataRetriever();
smr.setDataSource(<some url>);
String artist = smr.extractMetadata(ShoutCastMetadataRetriever.METADATA_KEY_ARTIST);
String title = smr.extractMetadata(ShoutCastMetadataRetriever.METADATA_KEY_TITLE);

I don't believe SHOUTcast metadata supports album art so you won't be able to retrieve that.

Answer 2

Since the class in the Answer of @William-Seemann is not usable anymore. Here's an alternative (with the benefit that it does not require any libraries):

Add the following class to your project. You can now use it as shown here. You can also use it like this:

    String title = "";
    IcyStreamMeta meta = new IcyStreamMeta();
    try {
        meta.setStreamUrl(new URL(YOURURL));
        title = meta.getStreamTitle();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
