Linux UVC driver and tools

Introduction

Welcome to the USB Video Class Linux device driver home.

The goal of this project is to provide all necessary software components to fully support UVC compliant devices in Linux. This include a V4L2 kernel device driver and patches for user-space tools.

The USB Device Class Definition for Video Devices, or USB Video Class, defines video streaming functionality on the Universal Serial Bus. Much like nearly all mass storage devices (USB flash disks, external SATA 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.

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.

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 are supported in bulk mode only.

Support requests are handled through the Linux UVC development mailing list. You need to subscribe to the list before posting. Don't forget to read the FAQ before sending an e-mail to the list.

Mailing list archives are temporarily unavailable.

Status

The Linux UVC projects is currently focussing on kernel support for UVC devices. The driver implements the Video4Linux 2 (V4L2) API. Support for the deprecated V4L1 API will not be added.

The following table lists the UVC features supported by the Linux UVC driver.

UVC Feature Status Comments
UVC 1.0 descriptors Yes
UVC 1.1 descriptors Yes
Camera input terminal Yes
USB Streaming terminal Yes
Processing unit Yes
Selector unit Yes
Extension unit Yes

Extension units can be accessed directly or mapped to V4L2 controls. They require a user-space management tool.

Still image capture No
Video streaming Yes
Uncompressed payload Yes
MJPEG payload Yes
DV payload Yes
MPEG-2 TS payload No
Frame-based payload Yes
Stream-based payload No

Supported devices

The table below lists known UVC devices. Other UVC compliant video input devices are very likely to be supported. If your UVC device is not listed below, please report it to the Linux UVC development mailing list. You need to subscribe to the list before posting.

1 First and second generation Logitech webcams suffer from firmware bug which make the camera somehow unstable. As the issue is timing-related, the exact impact of the bug on a particular user can't be predicted. If you plan to buy a Logitech webcam, consider getting one of the models not affected by the bug. More information about the issue, including possible workarounds, are available on the QuickCam Team website.

2 Starting at version 2.6.22, the Linux kernel includes a USB audio bug fix which triggers a (possibly identical to the above) bug in first and second generation Logitech webcams. See the Linux UVC wiki for a workaround.

3 This camera module is known to be mounted upside-down in some notebooks. Applications that use the libv4l library should display the video correctly, as libv4l detects upside-down cameras and rotates the image automatically. See Hans de Goede's post on the linux-uvc-devel mailing list for more information. For applications that don't use libv4l, try holding your computer upside-down.

4 iSight webcams require a proprietary firmware that can't be redistributed. Tools to extract the firmware from the MacOS X driver and load it into the device are available at http://bersace03.free.fr/ift/.

5 Video corruption has been noticed when the camera is connected to a USB 1.1 controller. For better performances, connect the camera to a USB 2.0 controller.

6 Some revisions of this model suffer from issues similar to those described in [1]. Only specific part numbers are affected. See Logitech UVC devices list for more information.

7 Creative Labs released at least two different devices under the Live! Cam Video IM Pro model name. While the one listed in this table is UVC compatible, the other(s) might not be. If in doubt, check the webcam USB product ID.

8 Resolutions below 640x480 might only work at the full 30fps frame rate.

9 This Device ID is known to be used by several different webcams among which at least one is currently not supported by the driver. If you plan to buy this camera make sure it matches the product name.

10 The camera has been reported not to work when connected to a USB 1.1 hub.

11 Those cameras claim to have a true 1.3MP or 2MP CMOS sensor, but the highest resolution reported by the UVC descriptors is 640x480.

12 Recent versions of the device use UVC as a fa├žade. They talk a vendor-specific protocol with a vendor-provided Windows driver, and trying to handle them with the UVC protocol results in low frame rate and corrupted frames in most resolutions. Device BCD 1.00 is known to be affected, BCD 0.02 seems to work.

13 Despite being able to work with lower USB bandwidths, this device always requests the maximum possible bandwidth, even for the MJPEG format. Using one of those cameras in conjunction with another USB device (including the camera internal microphone) will likely fail. You can tell the uvcvideo driver to estimate the required bandwidth instead of trusting the camera by setting the FIX_BANDWIDTH quirk. This will only affect uncompressed formats, and even there there's no guarantee of success. See the FAQ for more information.

14 The camera severely underexpose images under low-light conditions when using any frame rate other than the default (which also happens to be the maximum), probably because auto-exposure is only enabled at the default or maximum frame rate. The RESTRICT_FRAME_RATE quirk has been added to the driver to ignore all non-default frame rates.

15 Some versions of this camera have been reported to randomly time out or stall in response to valid UVC control requests, probably as a result of a race condition bug in the camera firmware. This can sometime lead to the camera failing to be recognized by the kernel. Little can be done to fix the problem.

16 At least some versions of this camera severely overexpose images when the manual exposure control is set to a value other than 2500 divided by an exponent of 2. Auto-exposure isn't affected.

17 Full-resolution scans are only possible through still image capture, which the uvcvideo driver doesn't support yet.

18 This camera might have issues with USB auto-suspend on Linux kernels between v2.3.37 and v3.5 (inclusive). See the FAQ for more information.

Download

Linux 2.6.26 and newer includes the Linux UVC driver natively. You will not need to download the driver sources manually unless you want to test a newer version or help with development.

Source code for the Linux UVC kernel driver is maintained in a GIT repository on linuxtv.org.

The old SVN repository has been archived and isn't available on the SVN server anymore. The repository archive can be downloaded here.

Documentation

UVC-specific parts of the driver API are documented in the Linux kernel tree starting at version 2.6.38, in Documentation/video4linux/uvcvideo.txt. Older kernel versions implemented a different API that is now deprecated and scheduled for removal in 2.6.39.

If you're upgrading from a pre-2.6.38 kernel, you should upgrade your userspace UVC tools. Instructions to install the latest uvcdynctrl tool are available from the QuickCam Team website. Standard V4L2 applications do not need to be upgraded.

More (mostly outdated) information can be found in the unofficial wiki.

For kernel developers, the USB Video Class specification is available on the USB Implementers Forum website.
