IMPORTANT: In order to compile this files you need the OpenCV module, you can download from http://opencv.willowgarage.com/wiki/Getting_started?action=AttachFile&do=view&target=FindOpenCV.cmake

NOTE: When compiling you could have problems with a cvconfig.h, apparently this is a OpenCV bug but only need copy this file to your OpenCV's include directory.

For some reason the Image is not saving after I enter in the name.

If I run:

kcmshell4 kcm_useraccount

as user I get:

mmap: Invalid argument
munmap: Invalid argument
munmap: Invalid argument
munmap: Invalid argument
munmap: Invalid argument
Unable to stop the stream.: Bad file descriptor

I'm running Mandriva

and using a UVC based Webcam

I went ahead and added a picture from the system and now it works. Looks like it may not be generating the userFaceDir if one doesn't exist?? Not sure. Something to look into.

Hello,
i tested this app under kde 4.4.1 (mdv 2010.1) without success:
it's recognizing my webcam, i'm able to take a screenshot, to save it (well at least it's asking for the file name) but after nothing happends : the avatar does not change
According to systemsettings configuration, kde is supposed to use by default user's avatar

Regards,

Hi, is very weird.
When you take a picture does this appear with the rest of the images? you also check if the picture is saved in ~/.face directory

Report

either more there 's no pic saved in ~/.face which did not exist initially
after creating this folder it still does not save inside this folder.

I would suggest you change it to say profile instead of face. When I saw the screenshots I was immediately struck by how weird it was to read that the program would "change my face". At that point, I thought to myself, do I really want to use this program?

The window title "Chage your face" and "select a new face" are not my responsability, this are original window title in KCM

I have some problems with review board, apparently the file header of my patch files is incorrect or not supported. I have something like this:

chfacedlg.h 2010-02-03 01:38:50.714194628 -0300
chfacedlg.h 2010-01-30 18:23:05.000000000 -0300

And Review board needs something like this:

http.cpp (revision 1083209)
http.cpp (working copy)

I use diff -u -p someone can help me?

try to use the command
svn diff
instead. It always produced the output required by reviewboard for me. but you need your changes based on an svn checkout from the original kcm module.

It would be nice if developers included a set of installation instructions.

There was a time when just about every package included some basic install and configuration instructions.

The lack of such severely limits the number of people who would use and try new software.

I send the patch to kde-devel mailing list, but I had no response...

Think kde-core-devel is more appropriate.

Try asking again, it needs to get in! :)
Maybe using reviewboard will help the process of reviewing it...
