Mac webcam problem (videoinput)

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.
