Hi,
I'm trying to use my USB webcam in Matlab/Image Acquisition
Toolbox.
The webcam works with AMcap.exe utillity, so I was hoping
it will also work in Matlab.
But when I use command "imaqhwinfo('winvideo')" I get this
message:
-------
AdaptorDllName: 'C:\Program
Files\MATLAB\R2007a\toolbox\imaq\imaqadaptors\win32\mwwinvideoimaq.dll'
AdaptorDllVersion: '2.1 (R2007a)'
AdaptorName: 'winvideo'
DeviceIDs: {1x0 cell}
DeviceInfo: [1x0 struct]
-------
"DeviceIDs" and "DeviceInfo" are empty. And after typing
"vid = videoinput('winvideo')" an error occured
-------
??? Error using ==> videoinput.videoinput at 233
There are no devices installed for the specified
ADAPTORNAME. See IMAQHWINFO.
-------
Is my webcam using another adaptor?
(InstalledAdaptors: {'coreco' 'demo' 'winvideo'})
Is it possible that the webcam would by useless in Matlab
even if it works with AMcap utillity? (in accordance with

Thank you for any answer. Have a nice day.
