==Webcam Devices supported by Generic Linux Drivers==

Many recent, as well as currently available, webcam models are supported, or likely can be supported, by one of the two generic Linux drivers:
  
[[Wikipedia:USB_video_device_class|USB Video Class (UVC)]] is a USB specification which defines and standardizes video streaming functionality on the Universal Serial Bus. USB video streaming devices (which covers a broad spectrum of possible devices, such as webcams, digital camcorders, ... ) that are compliant to the UVC specification are referred to as UVC devices.  A primary benefit brought about by the UVC specification is that UVC compliant peripherals can all be managed by a single generic driver.  Under Linux, UVC compliant devices are supported by (brace for it) the [http://linux-uvc.berlios.de/ Linux UVC device driver] (which may also be referred to as linux-uvc or uvcvideo).  Most modern webcams are UVC compliant, which is actually a good thing, because in the past webcam drivers and interfaces were often proprietary (meaning that Linux drivers needed the author to sign an NDA, or to decompile or monitor/sniff USB traffic).

The Linux UVC device driver was included in the kernel as of 2.6.26.  Some of the devices supported by this driver include:
+
* See [[gspca devices]] for a list of supported devices under this framework
* several USB2.0 Logitech Quickcams, such as:
+
** the Quickcam Orbit MP
+
** the Quickam for Notebooks Pro (Note that the Quickcam for Notebooks Deluxe is not a UVC webcam; it's supported by the [[gspca]] driver described below)
+
** the Quickcam Fusion
+
:All those webcams are 1.3MP devices. They will also work in USB 1.1 mode, but are then limited to 640x480. In that case, you could go for the Quickcam Pro 5000, which is a 640x480 device
+
* the Dell Notebook
+
* and the Cisco VT Camera II
+
  
And while UVC webcams are well supported, you must be aware of a few issues:
+
==Other Webcam Devices supported by Specific Drivers==
 +
(alphabetized by driver)
  
* The linux-uvc driver is V4L2-only. This means applications which support V4L1 only will not work. V4L1 is officially deprecated, and have been removed from the kernel recently, so most drivers have or will switch to V4L2 anyway.
+
Some of the kernel device driver modules listed below are included within the Linux kernel, but many of these are out-of-tree kernel drivers.
 
+
* The 4 Logitech UVC webcams mentioned above compress images in MJPEG for resolutions up to 960x720. This means that applications must be able to decompress MJPEG streams to use the webcam at lower resolutions. [http://www.gnomemeeting.org/ Ekiga] and [http://www.lavrsen.dk/twiki/bin/view/Motion/WebHome motion] support MJPEG compression. UVC webcams like the OmniVision OV2640 (built into Dell M1530 and Inspiron laptops) actually *require* MJPEG compression for high resolutions up to 1600x1200, whereas using the standard YUV encoding limits resolution to standard 640x480.
+
 
+
==gspca driver==
+
 
+
This driver is a major effort to support all sorts of webcams. It consists of a core module ([[gspca_main]]) and several sub-drivers.
+
 
+
Its development started with [http://mxhaard.free.fr/ spca5xx] support. The original driver used the old V4L 1 API spec. The current driver has support to V4L2 API and is integrated in Kernel.
