Computer Vision with OpenCV 3 and Qt5

Using the moveToThread function

As we mentioned earlier, you can also use the moveToThread function of any QObject subclass to make sure it is running in a separate thread. To see exactly how this works, let's repeat the same example by creating exactly the same GUI, and then creating a new C++ class (same as before), but, this time, naming it VideoProcessor. This time though, after the class is created, you don't need to inherit it from QThread, leave it as QObject (as it is). Just add the following members to the videoprocessor.h file:

    signals: 
      void inDisplay(QPixmap pixmap); 
      void outDisplay(QPixmap pixmap); 
 
   public slots: 
      void startVideo(); 
      void stopVideo(); 
 
  private: 
      bool stopped; 

The signals are exactly the same as before. The stopped ...
