Description Suske 2008-07-14 20:11:54 UTC

Version:           0.50.1 (using 4.0.4 (KDE 4.0.4 >= 20080505) "release 15.1", compiled sources)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.25.5-1.1-default

I am using Kopete 0.50.1 on KDE 4.0.4 OpenSUSE. I have a problem with my webcam Logitech Quickcam messenger. When i select video in Kopete's configuration it detects my webcam and shows ZC301-2 on the input drop down box. But the Standard box is empty. After i have selected video in configuration my webcam's LED is on and stays on. But there is no image in the square that is supposed to have the webcams output ! When i then try to open in Ekiga softphone i get an error message "Error while opening video device /dev/video0"

When not staring Kopete first my webcam is working fine with Ekiga softphone and video and sound work in this application.

I am using gspca driver.
USB Webcam has following id :  idVendor=046d, idProduct=08da

How can i diagnose the issue ? It doesn't seem a driver problem as the cam works fine in Ekiga.

I can confirm this for Logitech QuickCam Chat which I have and am also using GSCPA as well.

Any relation with this https://bugs.kde.org/show_bug.cgi?id=169560 report? Will the "tip" in https://bugs.kde.org/show_bug.cgi?id=169560 help regarding the issues reported here?

Comment 3 Johannes Wienke 2009-02-19 17:25:25 UTC

Forgot to mention that I'm using kopete 0.70.0

Comment 4 Johannes Wienke 2009-02-19 17:26:45 UTC

Oh sorry, this posting was not meant for this bug report. Somehow I got confused by bugzilla.

Comment 5 Frank Schaefer 2010-01-17 12:52:41 UTC

openSUSEs kopete-package is currently compiled without libv4l-support (I filed a bug-report).
Does the webcam work when you install libv4l and start Kopete from the terminal with

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so kopete

?

SVN commit 1087015 by ahartmetz:

Do not refuse to build without libv4l2 because Kopete also works without v4l,  
only the webcam part won't work. Note to bug reporters using source distros:
you should know what you're doing and understand dependencies.
It's also incosistent to depend on something that is really not essential  
only when compiling on a specific platform. libv4l is also not easy to
impossible to compile on old kernels where the rest of Kopete works fine.
This reverts the last commit.

Comment 10 Frank Schaefer 2010-02-18 16:43:13 UTC

Sorry for the noise. libv4l is now mandatory, which should fix your picture-problems. With KDE SC 4.5 we will provide improved image quality controls.

Concerning the interaction problem with Ekiga:
Of course, you can't capture from the same device with two applications simultanouously. However, adjusting picture settings (brighness, contrast, ...) from other applications is possible and works fine for me (tested with my own app).

The standard box is empty for most webcams, this is not a bug.

In the future, please file separate bug reports for each issue, thanks.
