println(Capture.list()); will show you the name all available cameras. than create Capture object with new Capture(this,width,height,camera name) Replace width,height and camera name with the correct values and make sure that the resolution is supported. I guess the issue is fixed in code, but there's no new release.

I think this may be fixed in video-2.0 release, (ie usually works with default first camera in list) but @MidnightNerd workaround should be used if not (eg on RaspberryPI ).
