On XP, if you have upgraded to SP2 it is critical to check for new video
drivers for whatever graphics chip the PCs have.

Have you tried doing an Open -- Open Capture Device, and just getting a
local display?  Make sure you plug in a valid value in the dshow size area
-- I would try 160x120 first, then maybe 320x240.

As long as the Webcam is DirectX compliant, it should work, if you do have
whatever logitech directshow drivers are available for the device. A quick
check indicates it's a basic USB camera -- correct?  There's a 2004 driver
out there, should be OK.  

98SE could be tougher -- it's a bit iffy, you have to be really careful on
patches/drivers, based on threads I've seen.

Good luck -- it sounds like an excellent project!

Hi folks,

I'm at the end of my rope, I've scoured google, the faq, the forums and the
mailing lists and haven't come up with anything.

I'm in the midst of working on a teleteaching project here in Nepal.
(I'm a computer scientist donating some time, so you don't have to ask me if
the cable was plugged in. ;-)

For this project, we were hoping to use VideoLan with an array of donated
Logitech Quickcam Express and a variety of window's boxes (I'm a linux guy
myself) running XP Home and 98SE. Videolan worked wonderfully on my Thinkpad
T23 with Logitech Notebook Pro 4000 back at the office, so I thought this
was going to be a piece of cake. 

No such luck.

On every system XP Home system I have access to here, I can blue screen the
system instantly by:

1) Using the wizard to start an HTTP stream from the camera, basically just
click refresh on the video device, click logitech and continue from there.

2) Opening the capture device, repeat the refresh and click configure, bomb.

3) doing 2 but not clicking configure and just continuing.

So, I read on one of the mailing lists that everything should be the latest
and greatest, but is that really realistic for most of the world?
Nevertheless, I downloaded the latest Direct X and Logitech drivers, still
crash city.

The message from bluescreen?
STOP: 0x0000007F (0x00000000,0x00000000,0x00000000,0x00000000)

If anyone has any tips on this, they are greatly appreciated. I'm not using
this to send porn into my bedroom (not yet), I'm using this to bridge the
education gap in remote villages in nepal. Getting this working really makes
a difference.

Thanks again,

Philip Mucci
