Ok, I found it. But your app stubbornly refuses to remember that I like "wide-and-low". If it remembered my preference, I'd be happy.

EDIT: Oh, and if you make a settings file, maybe have a "start fullscreen" setting too?

Alternatively, one could implement denoising and hot pixel removal filters, but that's heavy artillery outside the scope of this app...

Have you found a way to reduce the frames-per-second? Cutting the fps to 15 would probably improve the image dramatically, at the expense of some real-time motion responsiveness... Maybe another setting?

I notice that the screen flickers a lot; clearly, the device is trying to auto-adjust the brightness. It would be nice to kill that somehow. Hm. Someone who isn't as terrified of Bugzilla as I am should probably should post a bug about that.

Deal.

That can be set through gstreamer, I'll try and see whether it influences image quality.

This one, however, is a lot deeper, we have no control over camera gain ATM.

The quality of the picture is terrible. On the right hand side there is some kind of darker bar about 1 cm wide. And the application goes off in about 1 minute.

Thank you for the first working application which uses the front camera. Now we know that it's working and exists.

Maybe this lead to something.

I think I'll put up a startup notification bar that the image quality and the dark bar is not my doing :)

As for goes off... what do you mean ? The screen-save kicks in, the app crashes, or ?

I suppose it crashes by itself. If the screen saver goes on it comes on if you unlock screen saver. But there is no crash report alt ought I have reporter on.

I'm sorry not to recognize your startup notification

Yes, I noticed that too, the screen goes dark after a short period. Probably you should turn off screen blanking while your app is in the foreground...

It is killed after 2 min because .desktop file has X-Osso-Service=org.maemo.mirror, but program is not registered with libosso functions.

So remove X-Osso-Service from .desktop and it doesn't crash or use libosso. But because you are not using anything from libosso or dbus you can just remove it.

Actually, there is little point going higher res, as there is no device that could display it (remember, this is the videocall cam - how many phones do you know that have significantly better than 640x480 displays ? :) ). It *could* have been a better quality one, though :(

The new version gives "much" better picture than earlier. That seems to depend on illumination :p Thanks
