Greetings all;
I just bought some webcams, and the std viewer for a webcam has been
cheese for quite a while now. But its not part of TDE , and when I
had apt-get install it, it pulled in about 23 more megabytes worth
of dependencies.
AFAIK Cheese is a Gnome application, so I suppose that that particular
machine did not have (required) part of Gnome installed
(...)
Does anyone know of a TDE viewer that just works
for a webcam?
TDE no, but I usually use guvcview (which is Gtk+) that does fit my
(very limited) webcam requirements.

Thank you. That also segfaults, unless you give it a valid device name
argument, then it works. As does VLC. I've installed both v4l and v4l2
utility's but v4l2 can't find it, and will not accept text entry in the
open device box. So I guess its a simple v4l device.
Sitting here in the dark with nothing but the monitor for illumination,
its giving me a pretty quality decent pix of me, not that I can be
called decent sitting here in an undershirt. But nobody at 81 looks
good & I'm no exception. :( The front of the lens says 10x optical zoom,
but the only control I can find is optical focus. At this light level
its making about 8 fps. And to call it 640x480 is somewhat "carnival
barker" stretched. But it works, and given a solid mount, it can
probably be used as a locator device for machine vision. We have some
utility's that can control a milling machine so that it can be mounted
and aimed straight down, that can be used to first, calibrate its vision
offset from the machine, then offset the machine so we can find a
spot/registration mark, record it its X&Y location a couple times, and
which will then move the machine back to where the tool is on that spot.
And if the two registration marks aren't aligned along an axis, can
modify the gcode on the fly to align the machines paths traveled with
those marks even it its rotated 90 degrees when the workpiece was
clamped down on the table.
Thanks THierry. At least I know it can "make pictures" now. Which for a
less than 9 USD camera, amazes the heck out of me.
Cheers, Gene Heskett
