This article provides information on webcams and their use in Dell PCs with Ubuntu operating systems.
There are two basic types of webcam used with Dell PCs :
These are webcam that connect to the PC for use. Usually by the use of a USB cable.
These are built in to all of our Notebook and AIO (All in One) PCs. They are always connected and the cables are internal to the systems bezel.
Ubuntu linux being open source, doesn't use windows drivers. However the developers have made every effort to build in "out of the box" or "plug and play" support for a wide range of UVC (Universal Video Class) webcams into their operating systems and they have been getting better results with each revision since 7.10. This includes the integrated Webcams in use on Dell PCs.
Webcams often share similar or identical major components, even when they look quite different externally. This means that generic drivers may work for a variety of different makes and models. As stated above the idea is that once you have installed one of the more recent versions of Ubuntu - your webcam should just work.
However if your webcam doesn't Just Work, then being able to identify the device and check if it requires a specific driver comes in handy.
To identify your webcam properly, you will need to know :
The Make, Model Name or Number.
Any Version or Revision information.
This kind of information is often printed on the device or its packaging. (Such as Logitech, Lifecam or Creative Live and REV 01 or VER. 01.1.)
To get this kind of information from the system itself, we're going to use the Terminal utility : (CTRL + ALT + T)
Record the output of the lsusb command:
This command prints information about all of the devices connected to the USB bus. The information about your webcam will be on that list.
There's a second use of the same lsusb command to get additional information:
This version of the command lists the device's USB ID. This gives you a unique number to identify your device.
Linux Ubuntu Webcam drivers are provided by several different projects. Although the UVC project covers many devices, support for others is provided elsewhere.
This section aims to help you install your webcam's drivers if they have not been automatically installed by Ubuntu.
Get the linux Headers:
You need these so you can compile the drivers when they are downloaded.
Get the modules for your particular webcam:
You will need to enter the link address for the particular driver download you have identified for your particular device. (Usually you can get this from a web search or by requesting help from the Ubuntu Community forums.)
Move to the drivers directory and extract the source files from the tar files:
and change directory to where your sources are:
Where <driver name> is the name of the driver you are installing.
Prepare the installation files:
Compile the modules:
And install them:
Since Ubuntu Version 10.10, there has been a number of programs or applications which will work with or use your webcam. I'll give a quick list below with a quick description of what each program does :
This program is often used to test Webcam funcionality. The program captures video and stills from the webcam and can also apply some special effects.
This program was a long time default application which dealt with VoIP/Video Chat.
This program is an open source Movie player, but also has functions that allow you to choose a "capture device", to record from that device or stream the feed.
This is a audio / video recording and conversion and streaming application, that is cross-platform.
This application is able to display a webcam video stream.
This a companion application to MPlayer which can record from a webcam to video files.
Skype is a dedicated VoIP/Video Chat program, that Microsoft has made an open source version which it updates.
This is a package which provides a picture taking facility using the Terminal command line interface.
