Driver installation

Many cameras work out-of-the-box. If needed, try EasyCam, a tool for installing webcam drivers. If you are unable to manage installing your Webcam using EasyCam, you may try installing your camera manually. At the end of this page are some links to help you with this.

Testing your webcam

There is a nifty little application called camorama to view, alter and save images from a webcam. Simply install it via apt:

sudo apt-get install camorama

xawtv is another program you can use to test the camera.

sudo apt-get install xawtv

Additional software

If you want to have a little tray system icon that notifies you when your webcam is on, try Camera Monitor. There is even a debian/ubuntu package available. Webcam support is built in to aMSN, kopete and ekiga. As usual, install with

sudo apt-get install kopete
sudo apt-get install amsn
sudo apt-get install ekiga

Recording to an AVI file

MPlayer is capaple of displaying a webcam video stream, for example with the command line

mplayer tv:// -tv driver=v4l:width=640:height=480:device=/dev/video0

The resolution (width=??? & height=??? ) should be chosen to match the output of your device. The companion to MPlayer, MEncoder can record from a webcam to video files such as AVI, for example without audio:

mencoder tv:// -tv driver=v4l:width=320:height=240:device=/dev/video0 -ovc lavc -o webcam.avi

and with audio

mencoder tv:// -tv driver=v4l:width=320:height=240:device=/dev/video0:forceaudio:adevice=/dev/dsp1 -ovc lavc -oac mp3lame -lameopts cbr:br=64:mode=3 -o webcam.avi

Type 'man mencoder' for more info on the audio options. In the example, /dev/dsp1 refers to the webcam USB Audio device, while /dev/dsp would refer to the sound card You may need to install these programs with

sudo apt-get install mplayer mencoder

Edgy troubleshooting : pwc driver is broken

On Edgy, the pwc driver in the kernel is broken. List of the working webcams with pwc. An easy check to see if your pwc driver is broken :

$ lsmod | grep pwc

pwc 51964 1  <- Your driver is broken ! (around 50kb)

pwc 93984 0  <- your driver seems ok. (around 90kb)

How to get your webcam working ? 1) Install build-essential and the kernel-headers for your kernel (linux-headers-2.6.17-6-686 for me). 2) Download latest driver from http://www.saillard.org/linux/pwc/ (http://www.saillard.org/linux/pwc/files/pwc-10.0.12-rc1.tar.bz2 for me) 3) Unpack and go into extracted directory 4)

make

5)

sudo modprobe -r pwc

6)

sudo cp pwc.ko /lib/modules/`uname -r`/kernel/drivers/media/video/pwc/pwc.ko.saillard

7)

cd /lib/modules/`uname -r`/kernel/drivers/media/video/pwc

8)

sudo mv pwc.ko pwc.ko.ubuntu

9)

sudo ln -s pwc.ko.saillard pwc.ko

10)

sudo depmod -a

11)

sudo modprobe pwc

12) Enjoy! :)
