Implement video streaming in java me using rtsp - java-me

Question

I want to implement video streaming in java me using rtsp url. When tested the code on devices, I get Media Exception stating Prefetch Error-33. Here's my code
private void startStreaming()
{
try
{
mplayer=Manager.createPlayer(videourl);
mplayer.addPlayerListener(this);
mplayer.realize();
videoControl=(VideoControl) mplayer.getControl("VideoControl");
if(videoControl!=null)
{
Item video=(Item) videoControl.initDisplayMode(videoControl.USE_GUI_PRIMITIVE, null);
videoControl.setVisible(true);
System.out.println("Playing");
Form v=new Form("Playing Video");
StringItem si=new StringItem("Status", "Playing....");
v.append(video);
display.setCurrent(v);
}
mplayer.prefetch();
mplayer.start();
}
catch(Exception noCanDo)
{
Form f=new Form("Error");
f.append("Error : "+noCanDo);
display.setCurrent(f);
}
}
I have also tried using alternative method of using MIDlet.platformrequest(videourl) method which invokes default internal player of device to play video file. The player is being started but later on, a connection timeout prompt occurs. I have however tested the rtsp url and it works very much fine. Any suggestions as to how can I do video streaming using rtsp url in java me?

Use this code for streamin RTSP,it should work for nokia symbian belle sdk 1.1 and nokia sdk 2.0
protected void startApp() throws MIDletStateChangeException {
VideoCanvas VC = new VideoCanvas(this,url);
Display.getDisplay(this).setCurrent(VC); }
}
//videoCanvas Class
public VideoCanvas(ExampleStreamingMIDlet midlet, String url) {
this.midlet = midlet;
this.url = url;
addCommand(start);
addCommand(stop);
addCommand(back);
addCommand(exit);
setCommandListener(this);
this.setFullScreenMode(true);
}
public void commandAction(Command c, Displayable arg1) {
if(c == start) {
start();
}
public void start() {
try{
Player player = Manager.createPlayer(url);
player.addPlayerListener(this);
player.realize();
control = (VideoControl)player.getControl("VideoControl");
if (control != null) {
control.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this);
control.setDisplaySize(176,144);
int width = control.getSourceWidth();
int height = control.getSourceHeight();
status2 = "Before: SW=" + width + "-SH=" + height + "-DW=" + control.getDisplayWidth() + "-DH=" + control.getDisplayHeight();
}
player.start();
}
catch(Exception e) {
Alert erro = new Alert("Erro",e.getMessage(),null,AlertType.ERROR);
Display.getDisplay(midlet).setCurrent(erro);
}
}
public void stop() {
if(player != null) {
player.deallocate();
player.close();
}
}
