According to the SourceForge page, the VideoCapture binary is compiled against Python 2.2. You probably have that installed on your system somewhere, so it works fine at the command line. Current production versions of Zope run Python 2.1.3. I would guess this is the source of your problem. Perhaps your project is interesting enough the VideoCapture maintainers might release a binary compiled against 2.1.3? Dylan At 11:29 AM 2/27/2003, Tim wrote:
I've been playing with the python VideoCapture webcam module (http://videocapture.sourceforge.net/), and thought: wouldn't it be nice to wrap this in a Zope product! Yes, yes it would, I agreed with myself. Webcam controllable directly from Zope...
Unfortunately I quickly seem to have hit a hurdle I can not get over. The VideoCapture module can not seem to open the device when running under Zope. The code works perfectly fine, using Zope's python version, when run from the command line outside of Zope... but inside Zope the identical (cut/paste) code always fails.
The error message returned by the vidcap.pyd when trying to connect to the camera device is generic, so I can't see what specifically the problem is (if the windows error code is any more specific). I have the source, of course, but I'm not a c++ person so have no compiler. Anyhow it seems doubtful I'd be able to get around whatever the problem is.
I'm just wondering if anyone might be able to enlighten me on possible reasons for this behaviour. I think vaguely recall that Zope on Windows runs at some sort of lowered privileges (but i could remember incorrectly; I don't know how these sorts of things work on Win32). Could this be the cause? How might one get around this, if so?
