UVC Stands for 'USB Video Class'. It defines video streaming functionality on the Universal Serial Bus. UVC compliant peripherals only need a generic driver; much like mass storage devices (USB flash disks, External disc enclosures, etc.) can be managed by a single driver because they conform to the USB Mass Storage specification.

UVC Linux Driver

The GNU/Linux UVC Driver page is at http://linux-uvc.berlios.de/ and includes a list of supported devices

UVC support in Ubuntu

7.10 and later

In 7.10 the UVC module has been included which means that some webcams 'just work' however UVC is still at an early stage and device support and bugfixes are being added all the time. It may well be necessary to update to the latest version to get your hardware to work.

7.04 and earlier

UVC support is not included and you'll have to install it yourself.

Installing UVC

UVC has not released any 'snapshots' yet and has not been packaged and included in the Ubuntu repositories. There is a debian package located [url http://packages.debian.org/unstable/graphics/linux-uvc-source here] but the best way at the moment is to grab the latest build from the Subversion repository and compile it yourself.

Checkout from SVN

If you do not already have subversion installed get it with:

sudo apt-get install subversion

Then get that latest source from the repository with:

svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk

This will make the directory 'trunk' containing the source in your working directory

Build

Navigate to the 'trunk' directory containing the source and run:

make

Install

Ubuntu keeps the kernel module for UVC in /lib/modules/your kernel/ubuntu/media/usbvideo and the makefile has to be altered slightly to install to the correct directory. Open the the makefile in a text editor and change : INSTALL_MOD_DIR:= usb/media to INSTALL_MOD_DIR:= ubuntu/media/usbvideo then run

make install

Insert Modules

sudo modprobe uvcvideo

If you're running 7.10 this may complain that the module's already loaded. In that case unplug your camera and remove the old module with :

sudo modprobe -r uvcvideo

then insert the new one again as above
