Getting Metadata from Shoutcast stream Android

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";
//adele-someonelikeyou
//Accordossie
//http://support.k-designed.net/test-z/music/adele-someonelikeyou.mp3
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
public void onClick(View v) {
try {
if(paused == true) {
mediaPlayer.start();
} else {
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {

@Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();

}
});
}
paused = false;
image = retriever.getEmbeddedPicture();
if(image != null) {
albumpic.setImageBitmap(BitmapFactory.decodeByteArray(image, 0, image.length));
}
out = "Title: " + retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_TITLE) + " \nArtist: " + retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ARTIST);
title.setText(out);
play.setVisibility(ImageView.GONE);
pause.setVisibility(ImageView.VISIBLE);

} catch(Exception e) {
e.printStackTrace();
}
}
});

pause.setClickable(true);

pause.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
pause.setVisibility(ImageView.GONE);
play.setVisibility(ImageView.VISIBLE);
mediaPlayer.pause();
paused = true;
}
});

wish.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
Intent wishIntent = new Intent(MainActivity.this, Wish.class);
startActivity(wishIntent);

}
});

reservation.setOnClickListener(new OnClickListener() {

@Override

}
}

@Override

if (keyCode == KeyEvent.KEYCODE_BACK) {
moveTaskToBack(true);
return true;
}
return super.onKeyDown(keyCode, event);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

}


Thanks for your help!

Answer

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.
