MediaPlayer Video Problem

Hi, I have a little (big) problem to start a video with the MediaPlayer.

When I am starting the app, the Video should be played. But I can only hear the Sound.
I know that the solution for this Problem is to use the SurfaceHolder. But I am already using it.

I don't know if there is missing something in my Code or if the problem is somewhere else.
I already searched for solutions in this forum and with google, but i did not found any differences in the code structure.

This is my LayoutFile:

Syntax: [ Download ] [ Hide ]

<?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">
 
        <SurfaceView 
 
                android:id="@+id/surface" 
 
                android:layout_width="250px"
 
                android:layout_height="250px"
 
                android:layout_gravity="center"> 
 
        </SurfaceView>
 
</LinearLayout>

and this my ActivityClass:

public class Mainmenu extends Activity{

    private MediaPlayer mMediaPlayer;
 
    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.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 
 
        try 
 
        {
 
         mMediaPlayer = MediaPlayer.create(this, R.raw.test);
 
         mMediaPlayer.setDisplay(holder);
 
         mMediaPlayer.start();
 
        }
 
       catch(Exception e){Log.e(TAG, "error: " + e.getMessage(), e);}
 
       }
 
    }

I only want to know how to start a Video.
There is no error an no exception. The file is in the raw Folder and i can hear the sound without Problems.
I tried it with an mp4 and an 3gp videofile. The 3gp was captured with an G1.
And it makes no difference if i start the app with an emulator or with my G1.
So there must be something wrong with my code... but i dont know what.

Hi!

Is there any way to set video playback speed so video would play with speed 120%, 200% 20% or backwards -20% -100% ???

When I use command video.seekto(ms) while video is paused, it doesn't want to show that frame, until i call video.start(). But I don't want to play video from that frame, only set current frame and render it. I found great problems with using video.pause() command.

What to do to set video update image/frame when video is paused and I set frame with video.seekto(ms) command?

Thanks
