Unable to play video

[hiteshrawat]

Hi all,

I'm trying to run the following code, however its gives me nothing. Other than the video, everything's running fine. Please check through the code if you find anything going wrong.


else if (c == Demo)
{

form1.deleteAll();
form1.setTitle("Demo Video");
form1.removeCommand(Next1);
form1.removeCommand(Exit);


playFromResource();



}


public void playFromResource()

{

try

{

InputStream in = getClass().getResourceAsStream("/Video/Hitesh.mpeg");
if (in != null)
{
mPlayer = Manager.createPlayer(in, "video/mpeg");
}else
{
alert = new Alert("Alert", "No video", null, null);
display.setCurrent(alert);
return;

}
mPlayer.prefetch();

mPlayer.realize();
if((mVidc = (VideoControl)mPlayer.getControl("VideoControl"))!=null)

{

mVideoItem = (Item)mVidc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, null);
form1.append(mVideoItem);
}

mPlayer.prefetch();
mPlayer.start();
// form1.removeCommand(mPlayCommand);
display.setCurrent(form1);


}
catch (Exception e)

{e.printStackTrace();}

}

waiting for response.

Are you getting any exception if yes then please let us know so that we can slove your problem

[hiteshrawat]

Yes, when i tried running it with .3gp it gave me a media error but when i play with mpeg, it gives me that alert for input stream to be null.

i checked the location of the file and matched it correctly on the code also checked the .jar file....the file structure is same there too......

[ansh.chauhan]

change Manager.createPlayer(in, "video/mpeg"); with
Manager.createPlayer(is, "video/3gpp");

becoz you are using 3gp file. I m sure it will work

and for mpeg file i think your mobile will not support that

[hiteshrawat]

it gives me an error below



javax.microedition.media.MediaException: Cannot create a Player for: video/3gpp

[hiteshrawat]

well i believe there is somethings wrong with the code.............cause i have tried running this code on most of the phones...............

the error was on emulator.

phones i have tried on - Nokia N70, Sony Erricson K750i, I-mate(which hangs god knows why) and HTC(don't know the model)

[ansh.chauhan]

the error was on emulator.

Dont try to play 3gp file on emulator Most of the time emulator does not support 3gp

[hiteshrawat]

I tried running this on Nokia N 70............it gave me the alert which i coded to be shown when the input stream is null.............any guesses why it shows the input stream to be null???

[ansh.chauhan]

May be you were playing mpeg file .
Hey go through this link and let me know whether this help you or not

I tried running this on Nokia N 70............it gave me the alert which i coded to be shown when the input stream is null.............any guesses why it shows the input stream to be null???

Hi Hitesh,
Whats the error u get while playing the 3gp file. Have u handle the exception. I would like to suggest u that print those errors on some form or alert.

[hiteshrawat]

well what i did is that......i kept a try catch block

 InputStream in = getClass().getResourceAsStream("/Muzik/Airtel.3gp");
    if (in != null)
    {
    mPlayer = Manager.createPlayer(in, "video/3gpp");
    }else
    {
        alert = new Alert("Alert", "No video", null, null);
        display.setCurrent(alert);
        return;

    }

i'm showing a alert if the input stream is null...........and same is the message i'm getting again an again when i run it on the phone.

[raj_J2ME]

Hi,
if input stream is null then there is some issue while you are reading the file.please check that you have successfully read the file,like you should check that name,extension,type.

And follow the jitu's suggestion,print the stack trace of the exceptions that you might be getting.

[raj_J2ME]

well what i did is that......i kept a try catch block

 InputStream in = getClass().getResourceAsStream("/Muzik/Airtel.3gp");
    if (in != null)
    {
    mPlayer = Manager.createPlayer(in, "video/3gpp");
    }else
    {
        alert = new Alert("Alert", "No video", null, null);
        display.setCurrent(alert);
        return;

    }

i'm showing a alert if the input stream is null...........and same is the message i'm getting again an again when i run it on the phone.

HI,
please check that the file is on the correct path,like in the res folder,then Muzik and there must be Airtel.3gp file.
