getting video to play fullscreen android

edit

It looks like some issue of CameraBridgeViewBase implementation. I have reproduced the problem on Samsung GT-I9100 with Android 4.0.4 (CM) and add a ticket.

As a workaround you can inherit your own view class from any concrete implementation of CameraBridgeViewBase (JavaCameraView or NativeCameraView) and override calculateCameraFrameSize method. JavaCameraView class implements view with standard android java camera api. NativeCameraView class implements view with native OpenCV camera (VideoCapture).

For anyone still looking for this, I have solved the issue (sort-of). I cannot seem to get this to work for OpenCV v 2.4.3. I have tried everything on the internet. However, in OpenCV 2.4.3.2 they have added a way to set the camera size

disconnectCamera();
mMaxHeight = //your desired height
mMaxWidth = //your desired width
connectCamera(mMaxWidth, mMaxHeight);

Check out the OpenCV Tutorial 5(not included in 2.4.3 version), specifically the SampleJavaCameraView -> setResolution Method

Edit: Also, make sure in your manifests, you have

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

I think if you don't it can sometimes shrink the size slightly, depending on the screen size

You can get a list of the available resolutions or setup manually.

If you want to get the list of the available sizes and get the optimal camera size.

   if (mOpenCvCameraView != null) {
        List<Size> sizes = mOpenCvCameraView.getSupportedPreviewSizes();
        int mFrameWidth = width;
        int mFrameHeight = height;

        // selecting optimal camera size
        {

            double minDiff = Double.MAX_VALUE;
            for (Size size : sizes) {
                if (Math.abs(size.height - height) < minDiff) {
                    mFrameWidth = (int) size.width;
                    mFrameHeight = (int) size.height;
                    minDiff = Math.abs(size.height - height);
                }
            }
        }

        mOpenCvCameraView.set(Highgui.CV_CAP_PROP_FRAME_WIDTH, mFrameWidth);
        mOpenCvCameraView.set(Highgui.CV_CAP_PROP_FRAME_HEIGHT, mFrameHeight);
    }

If the optimal camera size is not fullscreen, it is easy to get the great size that the camera support from the list.

Other option is to set manually the size:

        mOpenCvCameraView.set(Highgui.CV_CAP_PROP_FRAME_WIDTH, 1000);
        mOpenCvCameraView.set(Highgui.CV_CAP_PROP_FRAME_HEIGHT, 800);

The source of the code is from Face Detection OpenCV version 2.4.2.

I'm experiencing the same problem with the camera, though I managed to solve it partially[*] by setting my activity to work in fullscreen mode.

Just add this before the setContentView in the onCreate method of your activity:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

[*] I said partially because still I can't select the resolution I want.
