|
This driver enable the use of video4linux compatible applications with the
|
|
Motion Eye camera. 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 (<param>=<value> when passing the option to the
|
|
module or meye.<param>=<value> on the kernel boot line when meye is
|
|
statically linked into the kernel). Those options are:
|
|
|
|
.. code-block:: none
|
|
|
|
gbuffers: number of capture buffers, default is 2 (32 max)
|
|
|
|
gbufsize: size of each capture buffer, default is 614400
|
|
|
|
video_nr: video device to register (0 = /dev/video0, etc)
|
|
|
|
Module use
|
|
----------
|
|
|
|
In order to automatically load the meye module on use, you can put those lines
|
|
in your /etc/modprobe.d/meye.conf file:
|
|
|
|
.. code-block:: none
|
|
|
|
alias char-major-81 videodev
|
|
alias char-major-81-0 meye
|
|
options meye gbuffers=32
|
|
|
|
Usage:
|
|
------
|
|
|
|
.. code-block:: none
|
|
|
|
xawtv >= 3.49 (<http://bytesex.org/xawtv/>)
|
|
for display and uncompressed video capture:
|
|
|
|
xawtv -c /dev/video0 -geometry 640x480
|
|
or
|
|
xawtv -c /dev/video0 -geometry 320x240
|
|
|
|
motioneye (<http://popies.net/meye/>)
|
|
for getting ppm or jpg snapshots, mjpeg video
|
|
|
|
Bugs / Todo
|
|
-----------
|
|
|
|
- 'motioneye' still uses the meye private v4l1 API extensions.
