getSnapshot returns null on Series 40

[borisman2]

Hello. I have two Series40 phones - Nokia/7500(5 ed.) and Nokia/6288(3 ed.)

1. I create player using locator capture://image
Player player = Manager.createPlayer("capture://image");
2. I obtain VideoControl
VideoControl vc = (VideoControl) player.getControl("VideoControl");
I display it in full screen on a canvas.
3.I realize and start camera
player.realize();
player.start();
Now I can CLEARLY can see the image on screen.
4. I'm trying to get image by calling:
byte[] data = vc.getSnapshot("image/jpeg");
or
byte[] data = vc.getSnapshot(null);

Both calls results the same - data becomes null.

Note that capture://video does not work for image capturing on Series 40.

Also please note that this code is returning null even on Nokia emulator.

Finally, if I change locator to capture://video, then this code works perfectly on Nokia/N72 (Series 60) and 4 different Sony-Ericsson devices (K750, Z530, W850, K850)

OOPS!

I've got exactly same error. I close camera before capturing image, because on SonyEricsson there is no other way to show user that camera is busy

How did you solved it?

My experience is that Nokia Series 40 handsets don't specify resolution in System.getProperty("video.snapshot.encodings")

So I fall back to my default encoding string:

    byte[] capturedImageBytes = videoControl.getSnapshot("encoding=jpeg&width=480&height=640");

This works on Nokia 5200, 3110 Classic, 6500 Classic, 5310 XpressMusic, etc.

Hello Steel,I looked at before posts and i am sure that now Nokia S40 dont supports.

Bu you have written that 3110 Classic. Are you sure that this works?

Because Our company will buy 200 phones related with encoding.

Hi Tyler

Yes, there's no question - MMAPI and getSnapshot works on the before mentioned Nokia Series 40 phones.
Perhaps you have some sort of preinstalled certificate & security policy from your network operator, which doesn't allow your midlet to access the camera?

Do you get a dialog up saying something like 'Allow access to multimedia?'
I don't have the Nokia phones here, so I can't remember the dialog exactly, but it works. I'm absolutely sure of that.

anyone resolved this problem??? I'm freaking out about it!

Only getSnapshot(null) works. and when I get a snapshot and use drawImage(...) the photo is so small(thats to bad).
