Please notice that it's a very simple and incompleted example to play stream video of 3gp format from internet using MediaPlayer.

MediaPlayer play stream video from internet


Modify layout to have a SurfaceView for the MediaPlayer.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<SurfaceView
android:id="@+id/playersurface"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

</LinearLayout>


MainActivity.java
package com.example.androidmediaplayer;

import java.io.IOException;

import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnPreparedListener;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.app.Activity;

public class MainActivity extends Activity implements SurfaceHolder.Callback, OnPreparedListener{

MediaPlayer mediaPlayer;
SurfaceHolder surfaceHolder;
SurfaceView playerSurfaceView;
String videoSrc = "rtsp://v6.cache1.c.youtube.com/CjYLENy73wIaLQkDsLHya4-Z9hMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYKX4k4uBjbOiUQw=/0/0/0/video.3gp";

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
playerSurfaceView = (SurfaceView)findViewById(R.id.playersurface);

surfaceHolder = playerSurfaceView.getHolder();
surfaceHolder.addCallback(this);
}

@Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub

}

@Override
public void surfaceCreated(SurfaceHolder arg0) {

try {
mediaPlayer = new MediaPlayer();
mediaPlayer.setDisplay(surfaceHolder);
mediaPlayer.setDataSource(videoSrc);
mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

@Override
public void surfaceDestroyed(SurfaceHolder arg0) {
// TODO Auto-generated method stub

}

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

}
