In my application there is a video button. Here’s the code.
@Override
protected void onGUI1_Button1Action (Component c, ActionEvent event){
try {
String value = Capture.captureVideo();
if (value != null) {
final Form previous = Display.getInstance().getCurrent();
Form preview = new Form("Preview");
preview.setLayout(new BorderLayout());
MediaPlayer pl = new MediaPlayer();
if (!value.startsWith("file:/")) {
value = "file:/" + value;
}
pl.setDataSource(value);
preview.addComponent(BorderLayout.CENTER, pl);
preview.setBackCommand(new Command("Back") {
public void actionPerformed(ActionEvent evt) {
previous.showBack();
}
});
preview.show();
}
} catch (Exception ex) {
Log.e(ex);
Dialog.show("Error", "" + ex, "OK", null);
}
}
I picked up this code from github. I don’t want to broadcast the video on full screen. I need a video from camera was built into some container. That container must cover only part of the screen. I have built a GUI and put a container(Media Player) into some part of screen. How to change the code for this purpose?
Answer
You can place a camera view finder right into your app with a new cn1lib: https://github.com/codenameone/CameraKitCodenameOne
Overlaying native widgets has been possible for a year or so by now.
Original answer which was correct when it was written is below:
Embedding camera or overlaying component on the preview screen is not yet available in codename one.
This could be done using native interface with peer component. Have a look at how Native map was implemented here
