애플릿에서 라이브 스트리밍을 캡처 할 수 없습니다.

Question

IP 카메라에서 스트리밍되는 라이브 비디오를 캡처하기 위해 다음 코드를 실행하고 있습니다. Jframe을 사용하면 잘 작동하지만 일부 요구 사항에 대해서는 애플릿으로 포장해야합니다. 사람이 ... 내가 다음과 같은 오류를 얻을

내가 ...이 코드를 실행 할 수 있었다 애플릿의 init 메소드에서 내가 클래스의 객체를 불러 이 스레드는 ...

public void init() { 
     ViewCamera axPanel = new ViewCamera(rootPane); 
     axPanel.setOpaque(true); 
     new Thread(axPanel).start(); 
     getContentPane().add(axPanel); 

     // Execute a job on the event-dispatching thread; creating this applet's 
     // GUI. 
     try { 
      SwingUtilities.invokeAndWait(new Runnable() { 
       public void run() { 

        createGUI(); 

       } 
      }); 
     } catch (Exception e) { 
      System.err.println("createGUI didn't complete successfully"); 
     } 
    } 

내가 아니라 내 웹 페이지에 애플릿을 삽입 한
