Hi, All
Thanks to the developer of SarxosWebCam wrapper !
SarxosWebCam lib was updated to "webcam-capture-0.3.12", so i was trying and got success in updating the webcam class - we can choose any camera by the name.
Extra .JARS (sorry, no store for files, they were googled one by one on the net):
Class was updated.
