java - How to capture images using LWUIt VIdeoComponent

Question

I have tried using MediaComponent, but since it is now deprecated it wont be good moving forward. Also i was not able to get it to re-size to full screen on the form. I am trying to use VideoComponent to capture a screen shot in an S40 device. I cant find how to instantiate the VideoComponent properly for capturing an image and not playing a video.

Answer 1

You can use VideoComponent for capturing an image.

First, to instantiate the VideoComponent, you need to create a native peer:

VideoComponent videoComponent = VideoComponent.createVideoPeer("capture://video");
Player player = (Player) videoComponent.getNativePeer();
player.realize();
VideoControl videoControl = (VideoControl) player.getControl("VideoControl");

To capture the image, you have to start video component and use getSnapshot of Video Control:

videoComponent.start();
videoControl.getSnapshot(null);

If you want to resize the video component to full screen you can use:

videoComponent.setFullScreen(false);

Other posibility is:

videoComponent.setPreferredH(Display.getInstance().getDisplayHeight());
videoComponent.setPreferredW(Display.getInstance().getDisplayWidth());
