Change the video resolution when capturing a WEB-cameras

Question

Language: Java
It is used in addition: JMF
When capturing video from WEB-cameras with JMF - getting the video is at the lowest resolution.
Can you please tell how to change the video resolution?
The code by which the captured image (no SWING-forms):
MediaLocator getWebCam = new MediaLocator("vfw://0");
private Player player;
Timer timer = new Timer(40, this);
public BufferedImage grabFrameImage() {
Image image = null;
FrameGrabbingControl frameGrabbingControl = null;
if (player != null)
frameGrabbingControl = (FrameGrabbingControl) player.getControl("javax.media.control.FrameGrabbingControl");
Buffer buffer = frameGrabbingControl.grabFrame();
if (buffer != null)
image = new BufferToImage((VideoFormat) buffer.getFormat()).createImage(buffer);
if (image != null)
return (BufferedImage) image;
return null;
public WorkWithWebCam() throws NoDataSourceException, IOException, NoPlayerException {
initComponents();
player = Manager.createPlayer(Manager.createDataSource(getWebCam));
player.start();
private void jButton1ActionPerformed(ActionEvent e) {
timer.start();
public static void main(String args[]) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try{
new WorkWithWebCam().setVisible(true);
}catch(Exception ex){}
public void actionPerformed(ActionEvent e) {
panelMain.getGraphics().drawImage(this.grabFrameImage(), 0, 0, 400, 300, null);
P.S. Can you please tell how this forum can be identified code \ listing?

Hello,
I don't know if there is a way to change the video. But I think you can easily use your own videos by using a local .mpg or .3gp file via InputStream. Just change the player's parameters in video/mpg instead of capture://video.
Hope it helps...
