OpenCV 2.4.5 front camera preview is upside down?!
I tried to use my device front camera with this code :
<org.opencv.android.JavaCameraView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone"
android:id="@+id/tutorial1_activity_java_surface_view"
opencv:show_fps="true"
opencv:camera_id="front" />
It worked but the preview is upside down! How to fix it? I use OpenCV 2.4.5.
Here is my user interface file :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:opencv="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="match_parent" >
<org.opencv.android.JavaCameraView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone"
android:id="@+id/tutorial1_activity_java_surface_view"
opencv:show_fps="true"
opencv:camera_id="front" />
<org.opencv.android.NativeCameraView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone"
android:id="@+id/tutorial1_activity_native_surface_view"
opencv:show_fps="true"
opencv:camera_id="front" />
</LinearLayout>
Both of native camera and java camera have this problem.
