HOW TO: Fix Logitech QuickCam and GnomeMeeting

[Remix_88]

This fix is derived from a couple of posts in various topics and may work for more than just Logitech QuickCams, but I can't validate that as I don't have any other brand of web cam.

The Problem

After a fresh install of Hoary, GnomeMeeting produced the following error when I tried to use the web cam.

Error while opening video device /dev/video0

The Fix

$ sudo apt-get install libpt-pluins-v4l

Start GnomeMeeting and change the video plugin to 'v4l' in the GnomeMeeting Preferences (instead of 'v4l2') and set the channel to 0.

Your webcam should now be working.

AND THANK YOU! Now I can use my sisters quickcam as a security can while I'm at school. I tried to get it to work before and it didnt. NOW IT DOES!!!!!!

More thanks!

I thought it was going to be something to do with the pwc module. I'm using a Philips camera by the way.

If you're using a Labtec QuickCam, you need to do the same thing.
But first you'll have to get the drivers.
I used http://qce-ga.sourceforge.net

TV Card : PCTV Rave (can Use V4l2 and V4l)

i have done this but i have, my webcam freeze. i have v4l plugin but it doesn't work, if i use gqcam, gnomemeeting ou camstream, it's the same they freeze when my webcam start. Who can help me?
I hope you understand well because english is not my natural language

type the following in a terminal window

$ sudo gedit /etc/X11/xorg.conf

after u type your password a window should pop up with your X-Org configuration.

look for a section that says

Section "Module"

Make sure you have the following listed under it.

Load     "v4l"

If not add it. Mines looks like this

Section "Module"
	Load	"GLcore"
	Load	"bitmap"
	Load	"dbe"
	Load	"ddc"
	Load	"dri"
	Load	"extmod"
	Load	"freetype"
	Load	"glx"
	Load	"int10"
	Load	"record"
	Load	"type1"
	Load	"v4l"
	Load	"vbe"
EndSection

Note: I am using a ati video card. Dont know what you need to do to a config with a nvidia card. Maybe its the same. Dont know

Hope that helps you

I have always the same probleme, i don't think it's v4l problem, i think my pctv and my webcam make conflict, because my pctv card can use v4l2 and v4l, but i don't know how i can solve it.

Just finished installing this same driver.

It needs the kernel headers to compile. Search for linux-headers-686 in synaptic. Also, instead of running make directly, I used ./quickcam.sh which guides you through the process. (Check the updated instructions in the README file.)
Hope this helps.
