This driver requires the "Sony Laptop Extras" driver (which +can be found in the "Misc devices" section of the kernel configuration utility) +to be compiled and installed (using its "camera=1" parameter). + +It can do at maximum 30 fps @ 320x240 or 15 fps @ 640x480. + +Grabbing is supported in packed YUV colorspace only. + +MJPEG hardware grabbing is supported via a private API (see below). + +Hardware supported +------------------ + +This driver supports the 'second' version of the MotionEye camera :) + +The first version was connected directly on the video bus of the Neomagic +video card and is unsupported. + +The second one, made by Kawasaki Steel is fully supported by this +driver (PCI vendor/device is 0x136b/0xff01) + +The third one, present in recent (more or less last year) Picturebooks +(C1M* models), is not supported. The manufacturer has given the specs +to the developers under a NDA (which allows the development of a GPL +driver however), but things are not moving very fast (see +http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011). + +There is a forth model connected on the USB bus in TR1* Vaio laptops. +This camera is not supported at all by the current driver, in fact +little information if any is available for this camera +(USB vendor/device is 0x054c/0x0107). + +Driver options +-------------- + +Several options can be passed to the meye driver using the standard +module argument syntax (= when passing the option to the +module or meye.= on the kernel boot line when meye is +statically linked into the kernel).
