I am able to see my webcam using:
>>webcamlist
>>mycam=webcam
but I can't using video input.
Using imaqhwinfo I get:
>> imaqhwinfo
ans =
InstalledAdaptors: {'dcam'}
MATLABVersion: '8.3 (R2014a)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '4.7 (R2014a)
>>imaqhwinfo('dcam')
ans =
AdaptorDllName: '/Users/Fredy/Documents/MATLAB/Su...'
AdaptorDllVersion: '4.7 (R2014a)'
AdaptorName: 'dcam'
DeviceIDs: {1x0 cell}
DeviceInfo: [1x0 struct]
>> obj=videoinput('dcam')
Error using videoinput (line 233)
There are no devices installed for the specified ADAPTORNAME.
See IMAQHWINFO.
Using >>webcamlist I get the following information
>> webcamlist
ans =
'FaceTime HD Camera'
How can I access my webcam using video input
I have also tried:
>> obj=videoinput('FaceTime HD Camera')
and it didn't work.
Thanks in advance.

Hi, I have the same problem with my Logitech C920, on Seven, R2014a.
webcamlist returns : ans =
'Logitech HD Pro Webcam C920'
'USB2.0 UVC HD Webcam'
but imaqhwinfo returns : ans =
InstalledAdaptors: {'winvideo'}
MATLABVersion: '8.3 (R2014a)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '4.7 (R2014a)'
So I can't use may Logitech C920 with videoinput.
Have you found a solution?
Thanks in advance.
