Is Android 2.2 HTTP progressive streaming = HTTP Live Streaming?

Question

The Stagefrigh media framework (Android 2.2) supports HTTP progressive streaming.
What's that means? I.e. is this an HTTP Live Streaming protocol realization?
And how to use HTTP Live Streaming on Android, I mean what's the client - web browser, MediaPlayer or just "in-SDK" realization and I have to inherit from some class?
Thanx.

Answer 1

One big practical diffrence is that Stagefright media Framework supports mpeg3 streaming, which the old engine didn't. So you can use (shoutcast) mp3streams for example.

Here is a simple example of implementation, which streams a shoutcast URL: http://fr3.ah.fm:9000. Note that this only works on Android 2.2.

import android.app.Activity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class SimpleMusicStream extends Activity implements
  MediaPlayer.OnCompletionListener, MediaPlayer.OnPreparedListener,
  MediaPlayer.OnErrorListener, MediaPlayer.OnBufferingUpdateListener {

 private String TAG = getClass().getSimpleName();
 private MediaPlayer mp = null;

 private Button play;
 private Button pause;
 private Button stop;

 @Override
 public void onCreate(Bundle icicle) {
  super.onCreate(icicle);
  setContentView(R.layout.main);

  play = (Button) findViewById(R.id.play);
  pause = (Button) findViewById(R.id.pause);
  stop = (Button) findViewById(R.id.stop);

  play.setOnClickListener(new View.OnClickListener() {
   public void onClick(View view) {
    play();
   }
  });

  pause.setOnClickListener(new View.OnClickListener() {
   public void onClick(View view) {
    pause();
   }
  });

  stop.setOnClickListener(new View.OnClickListener() {
   public void onClick(View view) {
    stop();
   }
  });
 }

 private void play() {
  Uri myUri = Uri.parse("http://fr3.ah.fm:9000/");
  try {
   if (mp == null) {
    this.mp = new MediaPlayer();
   } else {
    mp.stop();
    mp.reset();
   }
   mp.setDataSource(this, myUri); // Go to Initialized state
   mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
   mp.setOnPreparedListener(this);
   mp.setOnBufferingUpdateListener(this);

   mp.setOnErrorListener(this);
   mp.prepareAsync();

   Log.d(TAG, "LoadClip Done");
  } catch (Throwable t) {
   Log.d(TAG, t.toString());
  }
 }

 @Override
 public void onPrepared(MediaPlayer mp) {
  Log.d(TAG, "Stream is prepared");
  mp.start();
 }

 private void pause() {
  mp.pause();
 }

 private void stop() {
  mp.stop();

 }

 @Override
 public void onDestroy() {
  super.onDestroy();
  stop();

 }

 public void onCompletion(MediaPlayer mp) {
  stop();
 }

 public boolean onError(MediaPlayer mp, int what, int extra) {
  StringBuilder sb = new StringBuilder();
  sb.append("Media Player Error: ");
  switch (what) {
  case MediaPlayer.MEDIA_ERROR_NOT_VALID_FOR_PROGRESSIVE_PLAYBACK:
   sb.append("Not Valid for Progressive Playback");
   break;
  case MediaPlayer.MEDIA_ERROR_SERVER_DIED:
   sb.append("Server Died");
   break;
  case MediaPlayer.MEDIA_ERROR_UNKNOWN:
   sb.append("Unknown");
   break;
  default:
   sb.append(" Non standard (");
   sb.append(what);
   sb.append(")");
  }
  sb.append(" (" + what + ") ");
  sb.append(extra);
  Log.e(TAG, sb.toString());
  return true;
 }

 public void onBufferingUpdate(MediaPlayer mp, int percent) {
  Log.d(TAG, "PlayerService onBufferingUpdate : " + percent + "%");
 }

    }

main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent">
 <Button
  android:text="Play"
  android:id="@+id/play"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"></Button>
 <Button
  android:text="Pause"
  android:id="@+id/pause"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"></Button>
 <Button
  android:text="Stop"
  android:id="@+id/stop"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"></Button>
</LinearLayout>
