QuickCam Messenger

mazouz_n · 02-27-2009, 12:19 AM

Hi all,
I want to use webcam under skype. I installed dkms-gspca.noarch package as mentioned here (http://wiki.centos.org/AdditionalRes...reList/Webcams), and when launching video test under skype, all is frozen and I'm forced to restart my PC.
I have centos5

Code:

$ /sbin/lsusb 
Bus 001 Device 001: ID 0000:0000  
Bus 002 Device 002: ID 046d:08da Logitech, Inc. QuickCam Messanger
Bus 002 Device 001: ID 0000:0000  
Bus 005 Device 001: ID 0000:0000  
Bus 003 Device 001: ID 0000:0000  
Bus 004 Device 001: ID 0000:0000  
Bus 004 Device 002: ID 046d:c03e Logitech, Inc. Premium Optical Wheel Mouse

How to avoid this ?

hi

gspca2

Starting with 2.6.27, the kernel ships with the new v4l2 based gspca2 driver, which replaces the old v4l1 based external gspca driver, which is needed for a large number of different webcams. Unfortunately most userspace programs are not aware of the new v4l2 API for devices formerly covered by gspca, meanwhile they need to be started using "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so <program>".

# apt-get update
# apt-get install libv4l-0
$ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

but you would use your package manager instead of apt-get to download libv4l-0

then edit the icon pathway for skype from command skype to
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

Hi aus9
I installed libv4l-0.4.0-1.i386.rpm and removed dkms-gspca.noarch, but skype till now can't detect webcam. What's wrong ?

hi

before we look at skype, can you post the output of this pls

Code:

lsmod | grep snd

I am assuming you know how to configure your sound and video devices in skype as well?

I am not familar with dkms-gspca.noarch so I want to look at what modules are loaded.

EDIT
to save me asking...later since you have yet to succeed..what is exact kernel name you are running pls...and a link to your packages you installed would be greatly appreciated.

(Me thinks maybe you are not running a more recent kernel)

Basically ...if hw works...your usb modules must be loaded and then the relevant webcam module(s) and then for gspca2 modules....a link to tell old software how to handle the new module.

Kernel version is

Code:

$ uname -r
2.6.18-92.1.13.el5

link for package "libv4l-0.4.0-1.i386.rpm" is
http://www.lfarkas.org/linux/packages/centos/5/i386/

aus9 · 03-04-2009, 05:26 AM

sheesh that kernel is relatively old.

I am on 2.6.28-7

and that prev link about gspca2 referred to a kernel which was 2.6.27.

could you do me a favour and update the kernel it might be just that easy.
