[partly RESOLVED] Skype problems with webcam

I bought Omega C91 webcam (t works on uvcvideo driver). It worked out-of-the-box with all camera applications, except Skype. In Skype options i have my camera on list ("Vega USB 2.0 Camera (/dev/video1)"), but clicking on "Test" causes

Skype Video Capture: Cannot open device '/dev/video0': Nie ma takiego pliku ani katalogu
Starting the process...
Skype Xv: Xv ports available: 0
Skype XShm: XShm support enabled

in console and no image.

The system is able to see the camera, it works. But I get this issue with Skype video test:

Re: [partly RESOLVED] Skype problems with webcam

Try this one...
If you have 32bit system , use this command

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

, otherwise

LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so skype

+ install lib32-libv4l http://aur.archlinux.org/packages.php?ID=20859 (for 64bit sistem)

You can always make an alias wink

alias skype="LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype"

Nema na cemu smile ...
you can make icon (launcher) that executes that command or add that command on session's start (gnome , kde) , change command that starts skype in the menu (openbox fluxbox ...) , make alias (~/.bashrc) , etc ....

Re: [partly RESOLVED] Skype problems with webcam

Ok, my problem is resolved. Skype propably has a bug, because i have webcam on /dev/video1 (/dev/video0 didnt exist), and when i've selected my /dev/video1 webcam in skype, it still looked for it in /dev/video0. Ive symlinked /dev/video0 to /dev/video1 and now it works.
But unfortunately this webcam wasnt worth hours in which i was resolving this. In day, even with shutters on window closed, its far to bright for this webcam for beign usable, and in the evening is far to dark. Brightness control in v4l2 controls dont help. I dont know if there is another way to tune its brightness?

Hi

I was having the same problem with my webcam and skype ,ie, the webcam was recognized but there was no picture/video. After running the above command and pressing 'Test' webcam in skype I got the following trace.

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
