java - Controlling camera settings -

i attempting adjust camera settings such exposure , white balance fmj library in java. can create player dynamically:

new net.sf.fmj.media.cdp.civil.capturedeviceplugger().addcapturedevices();  final java.util.vector vectordevices = capturedevicemanager.getdevicelist(null); player player = null; capturedeviceinfo cdi = ((capturedeviceinfo) vectordevices.get(2));  // simplicity  try {     player = manager.createplayer(cdi.getlocator());     player.start(); } catch (noplayerexception | ioexception e) {     e.printstacktrace(); } 

so need controls of player change camera settings:

control[] ctrls = player.getcontrols(); 

however, returning ratecontrol, when need framegrabbingcontrol grab individual frames , (i'm assuming) formatcontrol change camera settings (source).

if these not returned getcontrols(), doomed? same results these cameras: microsoft lifecam studio , built-in lenovo easycam
