Webcam Error
Hi~
I use USB Webcam which made by no famous maker.
but, it can work properly . I checked in Scanners and Cameras menu in Control Panel of Windows XP.
and it was work properly. and also supported VFW.
but why do I have to read following message in Debug and Trace Messeges tab.
Unable to select camera: http://www.w3.org/2003/05/soap-envelope:Receiver -> http://schemas.microsoft.com/xw/2004/10/dssp.html:UnknownEntry

and I couldn't use that camera in Webcam Service. what is the problem?
If you feel like code-diving, the source for the webcam service is in samples\sensors\webcam
As George mentioned, the directshow framegrabber is probably having trouble with the camera's usb interface.
One possible option is to try uninstalling your webcam driver and just plug the camera in. This will load the default windows usb driver for the device, which will support some basic formats (this works for the logitech cameras I've used).
cheers,
Rob
