can HTC diamond support MMAPI using j2me

I wanted to let my j2me project have the ability to take picutre using MMAPI(JSR135) So I check my HTC Diamond with the following code

import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;

public class jsrtest extends MIDlet implements Runnable,CommandListener{
    Form form;
    Thread thread;
    Command c=new Command("Exit",Command.EXIT,0);
    public jsrtest()
    {
        Display.getDisplay(this).setCurrent(form=new Form("JSR Test"));
        form.addCommand(c);
        form.setCommandListener(this);
        (thread=new Thread(this)).start();

    protected void destroyApp(boolean u){
        super.notifyDestroyed();
    }
    protected void pauseApp() {
    }
    protected void startApp(){
    }
    public void run() {
        checkJSR("MIDP2.0","javax.microedition.lcdui.game.GameCanvas");
        checkJSR("CLDC1.1","java.lang.Float");
        checkJSR("MMAPI","javax.microedition.media.Player");
        checkJSR("WMAPI","javax.wireless.messaging.Message");
        checkJSR("JSR75","javax.microedition.io.file.FileConnection");
        checkJSR("JSR082","javax.bluetooth.UUID");
        checkJSR("JSR135","javax.microedition.media.Control");
        checkJSR("JSR135_videocontrol","javax.microedition.media.control.VideoControl");
        checkJSR("JSR179","javax.microedition.location.Location");
        checkJSR("JSR180","javax.microedition.sip.SipConnection");
        checkJSR("JSR184","javax.microedition.m3g.Mesh");
        checkJSR("JSR211","javax.microedition.content.Registry");
        checkJSR("JSR226","javax.microedition.m2g.SVGImage");
        checkJSR("JSR229","javax.microedition.payment.TransactionRecord");
        checkJSR("JSR234","javax.microedition.amms.Module");
        checkJSR("JSR238","javax.microedition.global.Formatter");
        checkJSR("JSR239","javax.microedition.khronos.egl.EGL");
    }
    private void checkJSR(String jsr,String className)
    {
        try {
            Class.forName(className);
            form.append(jsr+" Supproted\n");
        } catch (ClassNotFoundException e) {
            form.append(jsr+" Not Supproted\n");
        }
    }
    public void commandAction(Command cmd, Displayable disp) {
        this.destroyApp(false);
    }
}

which shows MMAPI is supported on HTC Diamond.

so I test the following code on my HTC Diamond to see if camera works but failed:

private void test(){
     Player p;
     VideoControl vc;
     try{
       p = Manager.createPlayer("capture://video");
       p.realize();
       vc = (VideoControl) p.getControl("VideoControl");
       form.append(new StringItem("mmmmmmmm",""));
       if (vc != null) {
        form.append((Item)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, null));
       }
       p.start();
     }catch(Exception e){
        e.printStackTrace();
     }

}

On above code works fine on JAVA ME Platform SDK 3. Can anybody tell me why MMAPI doesn't works my mobile phone?

You can make an additional test to see if the video capture is supported:

if(System.getProperty("supports.video.capture") == null){
    //Video capture not supported
}

But I think the main problem is on this line:

form.append((Item)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, null));

try this:

    vc.initDisplayMode(VideoControl.USE_DIRECT_VIDEO, <a Canvas here>);
    vc.setDisplayFullScreen(true);
    vc.setVisible(true);
