J2ME Camera Problem..

[nilanchalapanigrahy]

Hi All,
I have a program where camera option is implemented .. Here the default resolution is 160 X 120..
Can i customize that... ???

I have used..
byte[ ] photo = videoControl.getSnapshot(null);

Instead if i use

videoControl.getSnapshot("encoding=jpeg&quality=100&width=2048&height=1536");
It neither takes the snapshot nor it gives any exception..
Any solution.. ? I need at lease 320 X 240 resolution....

Just try - videoControl.getSnapshot("encoding=png&width=240&height=320");

or

VideoControl.getSnapshot("width=240&height=320")


Which device you are trying it on ?

Please write any statement in requested form not in ordered way.

Also its not mandatory that whatever the encoding passed as param will get positive results..It depends on device to device.

Sorry - if my tone -- looked to be ordering... I just wanted to tell Nilanchala that its not needed - no offense intended! Sorry again.

And yes - as Jitu wrote -- its not mandatory that specified encoding is returned by getSnapshot(), as it depends on device capabilities too.

It works fine with the device... I was testing in emulator that time.. Anyways thanks..

One more thing in my code it have lil problem..
After i take snapshot it shows me the snap for few time and then again it start the video player even though i have stoped the video controller..
my code is :

public void run() {
takeSnap();
}

public void takeSnap() {
try {
byte[] photo = videoControl.getSnapshot("encoding=png&width=240&height=320");
snapshot = Image.createImage(photo, 0, photo.length);

this.removeCommand(cmdCapture);
this.removeCommand(cmdBack);
this.addCommand(cmdUse);
this.addCommand(cmdDiscard);

player.close();
if (player != null) {
player = null;
}
cameraThread = null;
if (videoControl != null) {
videoControl = null;
}

} catch (Exception me) {
}
}

Please suggest me if any mistaike in my code..

Looks to be some threading issue.
Try to set the Visibility of VideoControl to false.

VideoControl.setVisible(false);

and player.deallocate();
