Help me set video format

Question

Hi ALL!
I am trying to set the video format, but it doesn't work, can someone help me?
public void initDevice(int wantedHeight, int wantedWidth, int wantedDepth) {
System.out.println("<initDevice()>");
Vector videoDevices = CaptureDeviceManager.getDeviceList(new RGBFormat());
VFWDeviceQuery deviceQuery = null;
CaptureDeviceInfo deviceInfo = null;
for(int i = 0; i < videoDevices.size(); i++) {
deviceQuery = (VFWDeviceQuery) videoDevices.elementAt(i);
if(deviceQuery == null) {
continue;
deviceName = deviceQuery.getName();
deviceInfo = CaptureDeviceManager.getDevice(deviceName);
if(deviceInfo == null) {
deviceName = null;
continue;
Format[] formats = deviceInfo.getFormats();
int bitsPerPixel = 0;
for(int j = 0; j < formats.length && userFormat == null; j++) {
if(!(formats[j] instanceof RGBFormat)) {
continue;
userFormat = (RGBFormat) formats[j];
if(wantedHeight != userFormat.getSize().height) {
userFormat = null;
} else if(wantedWidth != userFormat.getSize().width) {
userFormat = null;
} else if(wantedDepth != userFormat.getBitsPerPixel()) {
userFormat = null;
if(userFormat == null) {
errorMessage = "Format not found in system devices";
return;
locator = deviceInfo.getLocator();
if(locator == null) {
errorMessage = "Device info not found";
return;
try {
player = Manager.createRealizedProcessor(new ProcessorModel(locator, new Format[]{userFormat}, null));
} catch(Exception e) {
errorMessage = "Player/Processor not found: "+e.getMessage();
player = null;
return;
// player.addControllerListener(this);
if(player instanceof Player) {
visualComponent = ((Player) player).getVisualComponent();
if(visualComponent != null) {
videoPanel.add(visualComponent);
((Player) player).start();
System.out.println("</initDevice()>");

Even though you have posted almost all of your code you don't give enough information.
Are there any exceptions being thown? In there are what is the stack trace? Is the programme running without any problem but there seems to be no effect on the transformation of the video dimensions??
