How to play video streaming in Java ME

Comments

hi I tried compiling this source but am getting some error.

      private ExampleMIDlet midlet = null; 

is one of the line having error, and each line having ExampleMIDlet midlet contains and error.

Next error was at

     Display.getDisplay(midlet).setCurrent(midlet.list);

how do i solve this error. both the error messages are same cannot find symbol.

it will be a gr8 help if you can help me out. I am trying to stream video from a web cam.

thanks in advance

You have to create a MIDlet named ExampleMIDlet :

Here is an example :

import javax.microedition.midlet.MIDlet; import javax.microedition.midlet.MIDletStateChangeException; import javax.microedition.lcdui.List; import javax.microedition.lcdui.Display;

public class ExampleStreamingMIDlet extends MIDlet {

public List list;

public ExampleStreamingMIDlet() { list = new List("Accueil", List.IMPLICIT); }

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

}

protected void pauseApp() {

}

protected void startApp() throws MIDletStateChangeException { VideoCanvas VC = new VideoCanvas(this); Display.getDisplay(this).setCurrent(VC); }

}

RTSP link?

Is the RTSP link rtsp://rtsp.youtube.com/youtube/videos/HtVbAazUekM/video.3gp still working?

I get the exception:

javax.microedition.media.MediaException: Cannot create a Player for: rtsp://rtsp.youtube.com/youtube/videos/HtVbAazUekM/video.3gp at javax.microedition.media.Manager.createPlayer(+45)

Thanks,.

Viraj.mehta - Prefetch error -2

Hello,

After implementation of this code, I get the alert 'Prefetch error -2'. The url is the live stream of an IP camera and it is in mp4 format h.264 baseline profile. Any ideas why this may be happening ?

Thanks,
