Hi! As the title of question suggest i need to acquire and view frame by camera in two separate thread, not in the same as is common using. The main scope of this splitting is that i've after make these thread parts of a server process and client process.
Since the common way to obtain frame (in a gray scale on my case) and view it is as i shown in tutorial1 sample:
public class Tutorial1Activity extends Activity implements CvCameraViewListener2 {
private static final String TAG = "OCVSample::Activity";
private CameraBridgeViewBase mOpenCvCameraView;
private boolean mIsJavaCamera = true;
private MenuItem mItemSwitchCamera = null;
private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
@Override
public void onManagerConnected(int status) {
switch (status) {
case LoaderCallbackInterface.SUCCESS:
{
Log.i(TAG, "OpenCV loaded successfully");
mOpenCvCameraView.enableView();
} break;
default:
{
super.onManagerConnected(status);
} break;
}
}
};
public Tutorial1Activity() {
Log.i(TAG, "Instantiated new " + this.getClass());
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "called onCreate");
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setContentView(R.layout.tutorial1_surface_view);
if (mIsJavaCamera)
mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.tutorial1_activity_java_surface_view);
else
mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.tutorial1_activity_native_surface_view);
mOpenCvCameraView.setVisibility(SurfaceView.VISIBLE);
mOpenCvCameraView.setCvCameraViewListener(this);
}
@Override
public void onPause()
{
super.onPause();
if (mOpenCvCameraView != null)
mOpenCvCameraView.disableView();
}
@Override
public void onResume()
{
super.onResume();
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, this, mLoaderCallback);
}
public void onDestroy() {
super.onDestroy();
if (mOpenCvCameraView != null)
mOpenCvCameraView.disableView();
}
public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
Mat mOutput = inputFrame.gray();
return mOutput;
}
}
instead to use the same class for the viewing of the Mat returned by onCameraFrame() i would that this is work of an other thread for example,
thread for acquiring:
public class AcquireThread implements Runnable, CvCameraViewListener{
// I know the interface class for siply acquire frames may be wrong
}
thread for viewing:
public class ViewThread implements Runnable, CvCameraViewListener2{
}
I hope someone can help me :D!!
