JMF 비디오 크기 조정

 

JMF 사용하여 Java 응용 프로그램에서 비디오를 재생하려고 할 때,  비디오가 재생 비디오 크게 표시하려면

아래의 코드와 같이 다른 jpanel gridbag 레이아웃이 안에 배치합니다.

 

채우기 제약 조건 추가 할 때 가로 세로 비율에 따라 비디오가 늘어납니다.

 

public class VideoPanel extends JPanel

{
       private Player mediaPlayer; 
       private File file; 
 
       public VideoPanel(String videoFile, String path)

       { 
               setOpaque(false); 
               file = new File(path+"/video/"+videoFile);  
 
               URL mediaURL = null; 
               try { 

                       mediaURL = file.toURI().toURL(); 
               } catch (MalformedURLException e) { 
                       e.printStackTrace(); 
               } 

               setLayout( new BorderLayout() );       
               Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true ); 
               try{
