Depends a lot on the type of webcam, but in any case it's a pretty
safe bet that (a) it's possible, and (b) there is no *specific* module
for the task.

That said, there are things like PIL which could be of use in this area,
and at least one specific webcam package (probably using calldll to get
to the library for the device) that has been posted in the past.

Thanks all, I think this is enought for now :)

Works fine with my lowcost cam (AIPTEK 3M). USB Driver from AIPTEK
installed - no problems with VideoCapture. Have you tried the AMCAP.EXE in
folder AMCAP? This is not Pytthon but checks the same interface...

As far as I understand it he uses a standard DirectX (8.0) interface
"Device". It is only necessary to provide a proprietary driver which
supports this. Probably no chance for *very* legacy hardware....

Cool... so it works well with perhaps "most" common webcams under
Windows (only). Not bad for a start. We can assume the OP is using
Windows then, unless he comes back with a big stick. <grin>
