Description Alvaro Aguilera 2009-06-16 03:27:28 UTC
Version:           0.70.90 (using 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 139", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.30-41-default

I can't get my UVC Logitech QuickCam working with Kopete. 
When I open the settings window, most of the time I only see green horizontal lines instead of the video stream. Now and then, the video stream is shown, but so saturated that it's actually worthless. Trying to reduce this saturation with Kopete's controls doesn't work. 

My webcam does work with Skype, luvcview, etc. 

Below I pasted the relevant parts of the output of hwinfo and lsusb, and attached a couple of screen captures.

could you also provide the output of kopete in a console ?
dmesg could be of help too.
Comment 6 Alvaro Aguilera 2009-06-16 14:38:51 UTC
When the green lines appear, there is the following output on the console:

VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUM_FMT: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUM_FMT: Invalid argument

Comment 8 Detlev Casanova 2009-06-20 19:54:18 UTC
Hmmm, I did not see you were using openSuse packages. Is there a way you can activate debug information on the kopete package ? Is there any kdenetwork-dbg or kopete-dbg packages in the openSuse repository ?

The error messages you see are totally normal and won't help in fixing this bug.

Could you also post the output of luvcview ?
Comment 9 Alvaro Aguilera 2009-06-20 20:05:15 UTC
>Is there any kdenetwork-dbg or kopete-dbg packages in the openSuse repository ?

well, I don't know if there are such packages available and I won't be willing to install a whole KDE developing version for the time being.

>Could you also post the output of luvcview ?

sure, here it is:

----------
luvcview 0.2.4

SDL information:
  Video driver: x11
  A window manager is available
Device information:
  Device path:  /dev/video0
Stream settings:
  Frame format: MJPG
  Frame size:   640x480
  Frame rate:   30 fps
Cleanup done. Exiting ...
Comment 10 Detlev Casanova 2009-06-21 18:42:58 UTC
When you find time, install kdelibs-debuginfo, kdebase-debuginfo and kdenetwork-debuginfo. They are present in the same repository as the ones you have already installed.

Without that, it will be hard to solve this issue.

>When you find time, install kdelibs-debuginfo, kdebase-debuginfo and
kdenetwork-debuginfo

and then? should I paste here the konsole-output?
Comment 12 Detlev Casanova 2009-06-21 21:56:34 UTC
Yes, from the top.
Comment 13 Alvaro Aguilera 2009-06-24 18:48:33 UTC
I installed the debuginfo packages, restarted the KDE-Session but no extra information is given, just the lines posted above:

VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUM_FMT: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUM_FMT: Invalid argument

two positive things since the update to kopete-4.2.90-84.5 (in opensuse notation): 

1. the controls to adjust brightness etc. now work and I can get a decent picture. The quality however, isn't as nice as in Skype or Ekiga, perhaps they use some noise-reduction filter. Does kopete support video plugins?

2. the problem with the green lines occurs only the first time you open the camera configuration window. If you close it and open it again, then it works (but you need to adjust the default values of brightness etc. to see something).
Comment 14 Matt Rogers 2009-09-06 04:09:28 UTC
uvcvideo is weird. My iSight camera uses uvcvideo and works just fine. ;(
Comment 15 Jeffery MacEachern 2010-12-27 09:33:47 UTC
@Alvaro: Are you still experiencing the problem with the green lines?  If not, can we close this report?
If the video quality is still noticeably poor relative to other applications with the same hardware, but it does work, that might be best saved for a separate report.
Comment 16 Alvaro Aguilera 2010-12-27 11:59:31 UTC
Under KDE 4.6 beta 2 kopete doesn't recognize my webcam at all anymore.

Please open a separate bug report for this issue, thanks.

Image controls have been reworked/fixed in KDE 4.4.0.
If you still encounter a bad image quality, please post a kernel bug report at the linux-media mailing list.

This is the only remaining issue and there is a good chance that it is fixed since KDE 4.4.1.
