no. normaly video devices appear as /dev/video0 etc but I also saw
/dev/video/0 so "/dev/video/_your_v4l2_device_" replace with your video
device.

the console does some guess on ctrl+o and uses the v4l1 as default. But
that doesn't work with v4l2. The ffmpeg behind the MovieLayer can open
it, via javascript

on console
ctrl-x
v = new MovieLayer(320, 240, "/dev/video0")
ctrl-x
add_layer(v)

320,240 = width, height most devices needs that setup, try different values

sometimes such devices needs some setup like channel tuning or switching
input. freej doesn't have such features, yet.

the "cheap cams" I tested all suck. They need hackish v4l1 kernel
modules, make trouble and have poor quality.
