Video4Linux camera capture.

The camerav4l driver captures images from V4l-compatible cameras. See below for notes on specific camera/frame grabber combinations.

Compile-time dependencies
Provides
Requires
Configuration requests
Configuration file options

Note that some of these options may not be honoured by the underlying V4L kernel driver (it may not support a given image size, for example).

Example
driver
(
  name "camerav4l"
  provides ["camera:0"]
)
Logitech QuickCam Pro 4000

For the Logitech QuickCam Pro 4000, use:

driver
(
  name "camerav4l"
  provides ["camera:0"]
  port "/dev/video0"
  source 0
  size [160 120]
  mode "YUV420P"
)

Kernel notes: with a little bit of tweaking, this camera will work with the pwc (Phillips Web-Cam) driver in the Linux 2.4.20 kernel. The stock driver recognizes the QC Pro 3000, but not the QC Pro 4000; to support the latter, you must modify the kernel source (add a product id in a couple of places in pwc-if.c). Milage may vary for other kernel versions. Also, the binary-only pwcx.o module is needed to access frame sizes larger than 160x120; good luck finding this and/or getting it to work (the developer spat the dummy and took down his website).

Update for pwc: The original source has been taken up by another developer and is now available from http://www.saillard.org/linux/pwc/. This new version also doesnt need the binary driver which is a bonus
