<h2><a name="introduction"></a>Introduction</h2>
<p>Welcome to the USB Video Class Linux device driver home.</p>
<p>The goal of this project is to provide all necessary software components
to fully support <acronym title="USB Video Class">UVC</acronym> compliant
devices in Linux. This include a V4L2 kernel device driver and patches for
user-space tools.</p>
<p>The <em>USB Device Class Definition for Video Devices</em>, or
USB Video Class, defines video streaming functionality on the Universal
Serial Bus. Much like nearly all mass storage devices (USB flash disks,
external IDE disk enclosures, ...) can be managed by a single driver
because they conform to the USB Mass Storage specification, UVC compliant
peripherals only need a generic driver.</p>
<p>The UVC specification covers webcams, digital camcorders, analog video
converters, analog and digital television tuners, and still-image cameras
that support video streaming for both video input and output.</p>
<p>Due to the limited available man power and the broad scope of the UVC
specification, the Linux UVC project will concentrate the development
efforts on video input devices, especially webcams. Video output devices
will be considered at a later time.</p>
<p>Please visit the
<a href="http://developer.berlios.de/projects/linux-uvc">BerliOS project page</a>
for support forums, <a href="https://lists.berlios.de/pipermail/linux-uvc-devel/">mailing list archives</a>
and source code repository.</p>
<h2><a name="status"></a>Status</h2>
<p>The Linux UVC projects is currently focussing on kernel support for UVC
devices. The driver implements the Video4Linux 2 (V4L2) API. Support for
V4L1 is <strong>not</strong> planned.</p>
<p>The following table lists the UVC features supported by the Linux UVC
driver.</p>
