问题
I have been working on VideoCapture with Codename one using
String file=Capture.captureVideo();
Media video = MediaManager.createMedia(file, true);
f.addComponent(BorderLayout.CENTER, video.getVideoComponent());
f.revalidate();
and once we do that the problem when we try to open the Media in a MediaPlayer component , the video appear too small for the screen most of the time , and sometime it get fit to the form ,
the question is : how can I adjust the media inside the MediaPlayer component to fill the whole form
Regards,
回答1:
This will work on the device (not simulator) but I would recommend this API:
video.setNativePlayerMode(true);

Because you wrote that your question is related to Codename One - Zoom, center and crop a video to force it to occupy all the screen, I give you the code that solved my issue. It's an external layout manager, you can adapt it to your needs:
package ...;
import com.codename1.io.Log;
import com.codename1.ui.Component;
import com.codename1.ui.Container;
import com.codename1.ui.Display;
import com.codename1.ui.geom.Dimension;
import com.codename1.ui.layouts.Layout;
/**
* This layout manager fits a MediaPlayer component to the available space,
* cropping the video similar to "fit" scale in Codename One. It requires that
* only one MediaPlayer component is added and that the video orientation of the
* MediaPlayer data source is the same orientation of the device (thanks to an
* external orientation listener). See:

public class AutoFitVideoLayout extends Layout {
int smallerVideoSize;
int longerVideoSize;
/**
* The costructor needs the width and the height of the video (the landscape

public AutoFitVideoLayout(int width, int height) {
if (width < height) {
smallerVideoSize = width;
longerVideoSize = height;
} else {
smallerVideoSize = height;
longerVideoSize = width;
}
}
@Override
public void layoutContainer(Container parent) {
for (Component current : parent) {
int videoWidth;
int videoHeight;
if (parent.getWidth() > parent.getHeight()) {
// Landscape orientation
videoWidth = parent.getWidth();
videoHeight = Double.valueOf((double) (parent.getWidth()) * smallerVideoSize / longerVideoSize).intValue();
if (videoHeight < parent.getHeight()) {
videoHeight = parent.getHeight();
videoWidth = Double.valueOf((double) (parent.getHeight()) * longerVideoSize / smallerVideoSize).intValue();
}
} else {
// Portrait orientation
videoWidth = parent.getWidth();
videoHeight = Double.valueOf((double) (parent.getWidth()) * longerVideoSize / smallerVideoSize).intValue();
if (videoHeight < parent.getHeight()) {
videoHeight = parent.getHeight();
videoWidth = Double.valueOf((double) (parent.getHeight()) * smallerVideoSize / longerVideoSize).intValue();
}
}
current.setSize(new Dimension(videoWidth, videoHeight));
current.setX((parent.getWidth() - current.getWidth()) / 2);
current.setY((parent.getHeight() - current.getHeight()) / 2);

public Dimension getPreferredSize(Container parent) {
if (parent.getWidth() > 0 && parent.getHeight() > 0) {
return new Dimension(parent.getWidth(), parent.getHeight());
} else {
return new Dimension(100, 100);
}
}
}
