I have two different USB logitech webcams, neither of which is detected by Skype. I have installed the SuSE RPM distribution of Skype Linux 2.0 Beta. Any ideas on what I might be doing wrong or what I can look at to try and figure this out? Or is opening a JIRA issue the best thing to do?

Here's my system information:
Linux sorrow 2.6.22.5-31-default #1 SMP 2007/09/21 22:29:00 UTC x86_64 x86_64 x86_64 GNU/Linux

Section from /var/log/messages as I plug in the webcam and start skype:

Also I used the ubuntu package getlibs to sort out dependencies.

SOme libs weren't 64 bit. I'll try the static library.

Jm

downloading dynamic-static version also fails.

Permissions on the video device are correct.

Any help appreciated.

epchris: gspca version bundled with your OS is out of date and doesn't have proper ioctl64/32 compatibility support. Download the latest from the gspca homepage and install and you should be fine (albeit with some crashes in the initial beta release).

John: You also need ioctl64/32 compatibility support in your driver. Unfortunately, this doesn't exist in the driver as yet, alas, I did create a patch to enable this. Although you also need some other patches from the webcam driver thread to get this camera working with Skype.

I'd recommend digging through the Skype 2.0 Beta thread in the Skype for Linux forum for more details.

Andy.

Hi,
I downloaded and installed:
gspcav1-20071214.tar.gz
from the site:
http://mxhaard.free.fr/download.html
and am getting the same errors. Can you specify which version you meant?

Thanks,
Chris

I have also a logitech webcam working with latest GSPCA (20071224) V4L, tested with several linux apps. But skype won't find the cam. Here is the /var/log/messages when loading GSPCA:

Andreas: Everything looks good there. Do the other programs run on the same system?

When you say Skype doesn't find the cam, do you get "No devices found" in the video devices section of Skype's configuration?

Andy.

Andreas Demmer

Thu Jan 3 2008, 07:29

Other programs do find the camera and can use it without any problems; I tested the Flash player, Kopete messenger, Ekiga VoIP chat and others.

Skype's config dialog shows "no devices found", right.

Is there any hint or clue what to do?

Andypoo

Is the video device /dev/video0 under the other applications (or something else?)

In a console, can you run:
lsof |grep "/dev/video"

whilst accessing the camera in another application.

If this doesn't reveal anything unusual, then please do this:

mkdir ~/.Skype/Logs

And then run Skype again, go to video options dialog, and then close Skype and send us the resulting .log file to this thread.

You can then delete the ~/.Skype/Logs directory.

Andrew.

Meanwhile the cam magically appeared in skype, not sure what part of my setup changed. But now I ran into the black preview bug. I have Compiz Fusion / XGL installed but switched back to KWin for testing video in skype, still nothing.

Please find the skype logfile [attachmentid=12505] attached, maybe you can find something useful in it! :-)

Hi -- this failed because Skype tried to output in I420 colourspace and the Xv overlay didn't support it.

Can you send the output from xvinfo and also let us know what video card driver you are using?

Thanks,
Andy.

Ok I just did, what you asked for and I got no errors while accessing my cam with vlc and running "lsof |grep "/dev/video" "

So I created the Logs folder and the logs are attached to this post.

Thanks for any help.

FWIW I also encountered this on ubuntu gutsty. It turned out that skype wasn't able to open my camera due to a simple permissions issue:

user@gutsy:/dev$ ls -l video0
crw-rw---- 1 root video 81, 0 2008-01-22 20:26 video0
user@gutsy:/dev$ sudo chmod 777 video0
user@gutsy:/dev$ ls -l video0
crwxrwxrwx 1 root video 81, 0 2008-01-22 20:26 video0

Once I made this change & restarted skype I was able to access my webcam

It would make more sense to ensure your user is in the video group and keep the original permissions.

I managed to get it working with XGL! Andypoo pointed me to the right direction with the missing I420 color support in XGL.
I opend a second X-Server (Xorg this time) on virtual display 1 and opend skype on this server. And - horray! - it worked! :-)

But now I am facing the issue that the cam only randomly seems to work, sometimes I need to close skype und use the cam with another app before getting the cam to work in a then reopened Skype.

Any hints?
