Question

I have a problem with playing video in mediaplayer. I have a sound but no video. I tried everything and can’t find solve. Or maybe you know how to play sdp file in videoview? Here’s the code:

public class TestStream1 extends Activity implements Callback{
MediaPlayer mMediaPlayer;
String SrcPath = "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov";
private SurfaceView mPreview;
private SurfaceHolder holder;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mPreview = (SurfaceView) findViewById(R.id.surface);
       holder = mPreview.getHolder();
       holder.addCallback(TestStream1.this);
       holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

       holder.setFixedSize(400,300); 
       mMediaPlayer = new MediaPlayer(); 
       try{
           mMediaPlayer.setDataSource(SrcPath);
           mMediaPlayer.setDisplay(holder);
           mMediaPlayer.prepare();
           mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
           mMediaPlayer.start(); 

       }catch(Exception e){
           Toast .makeText( TestStream1.this, "Fail", Toast.LENGTH_LONG).show();
       }

}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
        int height) {
    // TODO Auto-generated method stub

}
@Override
public void surfaceCreated(SurfaceHolder holder) {
    // TODO Auto-generated method stub

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

}
}

EDIT: layout file

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello" />
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <SurfaceView
            android:id="@+id/surface"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
    </LinearLayout>
</LinearLayout>

Some videos cannot be played in mediaplayer, if it doesn’t have the codec for its a/v or it is too complex or badly interleaved (Look at Logcat for signs about some). Could be one or more reasons. To make sure the mediaplayer can play the type of video you are asking it to play, save a video file of the same a/v codec and extension to your sd card and then try to play it using the default media player.
Meanwile, try using a videoView to check the video can be played.Your code seems all right.

Try this code :

package a.b;

public class TestStream1 extends Activity implements Callback{
    MediaPlayer mMediaPlayer;
    String SrcPath = "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov";
    private SurfaceView mPreview;
    private SurfaceHolder holder;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mPreview = (SurfaceView) findViewById(R.id.surface);
        holder = mPreview.getHolder();
        holder.addCallback(TestStream1.this);
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

        holder.setFixedSize(400,300); 
        mMediaPlayer = new MediaPlayer(); 

    }
    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width,
            int height) {
        // TODO Auto-generated method stub

    }
    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        // TODO Auto-generated method stub
        try{
            mMediaPlayer.setDisplay(holder);
            mMediaPlayer.setDataSource(SrcPath);
            mMediaPlayer.prepare();
            mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mMediaPlayer.start(); 

        }catch(Exception e){
            Toast .makeText( TestStream1.this, "Fail", Toast.LENGTH_LONG).show();
        }

    }
    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        // TODO Auto-generated method stub
mMediaPlayer.release();
    }
}

SurfaceHolders are created ansynchronously, so we have to wait until the surface has been created and then assign the returned surface holder object .
And I am using the following layout:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello" />
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <SurfaceView
            android:id="@+id/surface"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>
</LinearLayout>

The above solution should work.
