How can I play in HTTP streaming in MediaPlayer on Android?

Question

I want to play a live HTTP stream in my Android application, so I installed Windows Media Encoder 9 on another computer on the same local network and used it to create an HTTP audio streaming stream.

The direct HTTP stream is fine: I tested it, and it can be played back using Windows Media Player or VLC on a PC, and it can played back VLC for Android on my mobile device.

So, in my Android app, I wrote this code:

private MediaPlayer player = null; @Override public void onCreate(Bundle savedInstanceState) { StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder() .detectDiskReads() .detectDiskWrites() .detectNetwork() // or .detectAll() for all detectable problems .penaltyLog() .build()); StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder() .detectLeakedSqlLiteObjects() //.detectLeakedClosableObjects() .penaltyLog() .penaltyDeath() .build()); super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btnPlay = (Button)findViewById(R.id.play); address = (TextView)findViewById(R.id.address); btnPlay.setOnClickListener(new OnClickListener() { public void onClick(View v) { play(); } }); } private void play() { String serverIp; serverIp = address.getText().toString(); // get the uri address, for example http://xxx.xxx.xxx.xxx:2340 if (player == null) { player = new MediaPlayer(); } else { player.stop(); player.reset(); } try { Log.v("", "Init a new MediaPlayer"); player.setAudioStreamType(AudioManager.STREAM_MUSIC); Log.v("", "Set the stream type to STREAM_MUSIC"); player.setDataSource(this, Uri.parse(serverIp)); Log.v("", "Set the source is " + serverIp); player.setOnBufferingUpdateListener(this); player.setOnPreparedListener(this); player.setOnErrorListener(this); player.prepareAsync(); Log.v("", "After prepareAsync"); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block Log.v("IllegalArgumentException", e.toString()); } catch (SecurityException e) { // TODO Auto-generated catch block Log.v("SecurityException", e.toString()); } catch (IllegalStateException e) { // TODO Auto-generated catch block Log.v("IllegalStateException", e.toString()); } catch (IOException e) { // TODO Auto-generated catch block Log.v("IOException", e.toString()); } catch (Exception e) { Log.v("Exception",e.toString()); } } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } @Override public void onPrepared(MediaPlayer mp) { // TODO Auto-generated method stub try { Log.v("onPrepared", "After prepareAsync"); mp.start(); } catch (Exception e) { Log.v("play", e.toString()); } } @Override public void onBufferingUpdate(MediaPlayer mp, int percent) { // TODO Auto-generated method stub Log.v("onBufferingUpdate", "Buffering Update"); } @Override public boolean onError(MediaPlayer mp, int what, int extra) { // TODO Auto-generated method stub Log.v("MediaPlayer onError", "what=" + what + " extra=" + extra); return true; } 

But that did not work. When I press the play button, nothing happens. But if I enter another URL that I found on the Internet (e.g. http://www.example.com/song.mp3 ), it works.

So can someone help me? Information about the magazine is given below. My mobile phone is HTC s710e and the Android version is 4.0.4.

You can play HLS on Android 3.0 and 3.0+, older versions do not support HLS. This code below can work with version 3.0+. To play videos of all versions of Android, you must use rtsp streaming or http prograssive download.

Player class

 import android.app.Activity; import android.media.MediaPlayer; import android.media.MediaPlayer.OnBufferingUpdateListener; import android.media.MediaPlayer.OnCompletionListener; import android.media.MediaPlayer.OnPreparedListener; import android.media.MediaPlayer.OnVideoSizeChangedListener; import android.os.Bundle; import android.util.Log; import android.view.SurfaceHolder; import android.view.SurfaceView; public class VideoPlayerActivity extends Activity implements OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener, OnVideoSizeChangedListener, SurfaceHolder.Callback { private static final String TAG = "MediaPlayerDemo"; private int mVideoWidth; private int mVideoHeight; private MediaPlayer mMediaPlayer; private SurfaceView mPreview; private SurfaceHolder holder; private String path; private Bundle extras; private static final String MEDIA = "media"; private static final int STREAM_VIDEO = 5; private boolean mIsVideoSizeKnown = false; private boolean mIsVideoReadyToBePlayed = false; /** * * Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); mPreview = (SurfaceView) findViewById(R.id.VideoView); holder = mPreview.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); extras = getIntent().getExtras(); } private void playVideo(Integer Media) { doCleanUp(); try { path = "http://www.pocketjourney.com/downloads/pj/video/famous.3gp"; // Create a new media player and set the listeners mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(path); mMediaPlayer.setDisplay(holder); mMediaPlayer.prepare(); mMediaPlayer.setOnBufferingUpdateListener(this); mMediaPlayer.setOnCompletionListener(this); mMediaPlayer.setOnPreparedListener(this); mMediaPlayer.setOnVideoSizeChangedListener(this); //mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); } catch (Exception e) { Log.e(TAG, "error: " + e.getMessage(), e); } } public void onBufferingUpdate(MediaPlayer arg0, int percent) { Log.d(TAG, "onBufferingUpdate percent:" + percent); } public void onCompletion(MediaPlayer arg0) { Log.d(TAG, "onCompletion called"); } public void onVideoSizeChanged(MediaPlayer mp, int width, int height) { Log.v(TAG, "onVideoSizeChanged called"); if (width == 0 || height == 0) { Log.e(TAG, "invalid video width(" + width + ") or height(" + height + ")"); return; } mIsVideoSizeKnown = true; mVideoWidth = width; mVideoHeight = height; if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) { startVideoPlayback(); } } public void onPrepared(MediaPlayer mediaplayer) { Log.d(TAG, "onPrepared called"); mIsVideoReadyToBePlayed = true; if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) { startVideoPlayback(); } } public void surfaceChanged(SurfaceHolder surfaceholder, int i, int j, int k) { Log.d(TAG, "surfaceChanged called"); } public void surfaceDestroyed(SurfaceHolder surfaceholder) { Log.d(TAG, "surfaceDestroyed called"); } public void surfaceCreated(SurfaceHolder holder) { Log.d(TAG, "surfaceCreated called"); playVideo(STREAM_VIDEO); } @Override protected void onPause() { super.onPause(); releaseMediaPlayer(); doCleanUp(); } @Override protected void onDestroy() { super.onDestroy(); releaseMediaPlayer(); doCleanUp(); } private void releaseMediaPlayer() { if (mMediaPlayer != null) { mMediaPlayer.release(); mMediaPlayer = null; } } private void doCleanUp() { mVideoWidth = 0; mVideoHeight = 0; mIsVideoReadyToBePlayed = false; mIsVideoSizeKnown = false; } private void startVideoPlayback() { Log.v(TAG, "startVideoPlayback"); holder.setFixedSize(mVideoWidth, mVideoHeight); mMediaPlayer.start(); } } 

Core XML

  <VideoView android:id="@+id/VideoView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"/> <LinearLayout android:id="@+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:background="#aaaaaa"> </LinearLayout> </LinearLayout> 

And you must add to your explicit internet permission

 uses-permission android:name="android.permission.INTERNET" />
