Message

pauloref · Post by **pauloref** » Sun Nov 20, 2005 11:27 am

ok, I have a logitech webcam. (unfortunately i can't remember exactly the model as it is not writen on it) I think it is a Quickcam(almost sure). What must i do in order to configure it? I have V4L compiled in my kernel and in think i also have the modules as M in it. i have emerged qc-usb (whitch i think are the modules fow the logitech cams).

Please help me

pauloref,

First, be sure you have the right kernel modules.
You can look that up by getting the Vendor and Device IDs from /proc/bus/usb/devices. That file is a bit hard on the eyes, usbview makes it easy. (emerge usbview).

Its not so much what your cam is called, its the chip set it uses. Logitec Quickcams use at least three different chip sets I know of and one of them was not supported under Linux when I looked into it recently.

Post the Vendor and Device IDs if you can't use them to work out which kernel module you need.

pauloref,

You have a Quickcam-Messenger. Its not clear from google which driver you need. Some pages suggest the the original driver was updated to cover the Messenger, some say the driver was forked, yet others say its a new driver.

This page looks like a good place to start. You will not be able to emerge the driver and it will drop out every kernel update.
Notice your cam is listed by Vendor and Device IDs, thats a very good sign.

The driver is not in the kernel, unless its been added since 2.6.9
It looks like qc-usb is for the Logitech USB Quickcam Express, which is not what you have.

ok, i have instaled the driver. How can i know if it works? I have MSN(amsn) with suport for webcam and gnomemeeting, however it don't detect the webcam.

pauloref,

xawtv is is good application for testing video devices.

You should have a /dev/v4l/video0, which is your camera.

Code: Select all

xawtv -c /dev/v4l/video0

will show you the picture, if its working.
emerge xawtv if needed

pauloref · Post by **pauloref** » Sun Nov 20, 2005 3:02 pm

i have no /dev/v4l directory. However i have v4l as * in my kernel.

Post by **NeddySeagoon** » Sun Nov 20, 2005 3:18 pm

pauloref,

Do you have a real device called /dev/video0 ?

Hi,

Quickcam messenger works fine for me. It's been a while since I installed it so I'm not sure, but I think I just emerged a package. I thought it was qc-usb but I just found another package called qc-usb-messenger, which is also installed on my system, so I would suggest to try it :

Code: Select all

emerge qc-usb-messenger

Do not forget to load the module :

Code: Select all

modprobe quickcam

what seems to be buging is V4L

Ok it turns out I was using a non-official package.
You can find the .ebuild and the tarball at http://tachatte.org/share/

Have the ebuild in /usr/local/portage/media-video/qc-usb-messenger/ and the .tar.gz in /usr/portage/distfiles and I think it should be ok to emerge qc-usb-messenger.

Hi guys,
I have a samsung anycam mpc-c10 which is supported by this media-video/usb-pwc-re driver and there is also a driver but an older version in the kernel (vanilla-source 2.6.14.2) but I didn't put it in the kernel but I downloaded instead the driver mentioned above. In the kernel I have enabled of course the

I am sorry, i just checked my webcam, and I've just found out that I have a Samsung Anycam Junior MPC-M80 nad not a Samsung Anycam MPC-C10 as I first thought. So I suppose there is no way to solve my problem because this one isn't supported by the pwc driver. If anybody has any thoughts please tell me.
thanks

Yes I also figured it out that there is no driver for may cam. So that's it than.

It's also got an internal mic. How can I use that?

fuzzythebear,

In the days of this driver It just worked.
Try the new Phillips Webcam Driver (pwc) in the kernel under USB. I've had a lot of trouble with it
and have been thinking of going back to the old driver. You also need Video For Linux.
