Camera Issue in N78

[rabeehkm]

Hi experts,

I have made an camera application for N82 which is a Midp 2.0 device.
the application takes a photo and store it in the rms.
It is working properly in N82.
But when i tested it in N78 which is Midp 2.1 device, the application is not working. when i press capture, the application is getting hanged.

Please help me

Hi,

Thankx for the reply. i tried that already. still its not working.

here is my code

mPlayer = Manager.createPlayer("capture://video");
mPlayer.realize();
mVideoControl = (VideoControl)mPlayer.getControl("VideoControl");
raw = mVideoControl.getSnapshot("encoding=jpeg&width=320&height=320");
mPlayer.close();
mPlayer = null;
mVideoControl = null;

By this i am able to capture the image in N82, but not in N78.

One More thing, will a program designed for Midp 2.0 will work in Midp 2.1 device?

Please help

Hi,

same probelm also encountered with me in Nokia N78 and other MiDP 2.1 devices.

In your code , you have used mPlayer.close() after capturing the image.

use mPlayer.stop() instead of mPlayer.close().
This will fix the problem.

It is happening in all Midp 2.1 nokia devices like (N78, Nokia 6210, Nokia N96, Nokia N85, N79 etc.)

Hi,

Are you performing both tasks i.e. capturing and storing the images in a single thread. If thats the case then perform them in different threads. It may be possible that your application is going into deadlock due to lack of resources.

Hi,I also make a J2me program to invoke the camera of N78 to take a photo. I initialize and show the camera in a thread,capture the picture in another thread .Then the camera can play,when I capture the picture ,the sound of taking a photo is normal,but the flash light come late.The camera is still playing,the screen is not still,but the picture can not be captured immediately.After a while there is a warning"security Warning Allow application camera MiDlet to use Camera,Video player or audio application?".When I choose yes, the picture can be captured . How can I solve this problem? Thanks very much in advance.
