Android Camera recording video but plays upside down

Question

I record a video using the below code and it records perfectly, but when it plays the video, it plays it upside down.

I tried settings mrec.setOrientationHint(

Answer 1

I have the same problem, I note that camera preview orientation angle and recording video angle aren't the same. So I use this method for change orientation on video recording:

public static int getVideoOrientationAngle(Activity activity, int cameraId) { //The param cameraId is the number of the camera.
    int angle;
    Display display = activity.getWindowManager().getDefaultDisplay();
    int degrees = display.getRotation();
    android.hardware.Camera.CameraInfo info =
            new android.hardware.Camera.CameraInfo();
    android.hardware.Camera.getCameraInfo(cameraId, info);
    switch (degrees) {
        case Surface.ROTATION_0: 
            angle = 90; 
            break;
        case Surface.ROTATION_90:
            angle = 0;
            break;
        case Surface.ROTATION_180:
            angle = 270;
            break;
        case Surface.ROTATION_270:
            angle = 180;
            break;
        default:
            angle = 90;
            break;
    }
    if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT)
        angle = (angle + 180) % 360;

    return angle;
}

And that for change orientation on camera preview:

 public static int setCameraDisplayOrientation(Activity activity,
                                              int cameraId, android.hardware.Camera camera) {
    android.hardware.Camera.CameraInfo info =
            new android.hardware.Camera.CameraInfo();
    android.hardware.Camera.getCameraInfo(cameraId, info);
    int rotation = activity.getWindowManager().getDefaultDisplay()
            .getRotation();
    int degrees = 0;
    switch (rotation) {
        case Surface.ROTATION_0:
            degrees = 0;
            break;
        case Surface.ROTATION_90:
            degrees = 90;
            break;
        case Surface.ROTATION_180:
            degrees = 180;
            break;
        case Surface.ROTATION_270:
            degrees = 270;
            break;
    }

    int result;
    if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
        result = (info.orientation + degrees) % 360;
        result = (360 - result) % 360;  // compensate the mirror
    } else {  // back-facing
        result = (info.orientation - degrees + 360) % 360;
    }
    camera.setDisplayOrientation(result);
    return result;
}

Note that's important to know if the camera is front or back.
