使用JMF播放视频文件 [英] Playing video file using JMF

问题描述

我正在尝试使用JMF播放视频。我也在Ubuntu中使用netbeans。没有在程序中出现任何错误。但我不能打开视频。相反，我得到一个错误消息为没有找到媒体播放器的对话框。



实际上我编写的程序就像我点击按钮5，视频文件必须播放通过使用JFilechooser选择文件。

这是我的代码

I am trying to play a video using JMF. Also I am using netbeans in Ubuntu. Not getting any error in the program. but I cant open video. Instead am getting a dialog box having error message as "No media Player found".

Actually I have written program like when I click button5, the video file has to play by selecting file using JFilechooser.
Here is my code

private void jButton5ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
    try {
            openMedia();
        } catch (IOException ex) {
            //Logger.getLogger(SoundBytePlaying.class.getName()).log(Level.SEVERE, null, ex);
        }
}


public void openMedia() throws IOException{
        JFileChooser fileChooser = new JFileChooser();
        int result = fileChooser.showOpenDialog(jButton5);
        if(result == JFileChooser.APPROVE_OPTION)
        {
            URL mediaURL = null;
            try{
                mediaURL = fileChooser.getSelectedFile().toURL();
            }catch(MalformedURLException malformedURLException){
                JOptionPane.showMessageDialog(null, "Could not create URL for the file");
            }
            if(mediaURL != null){
                showVideo(mediaURL); //some error here**
                System.out.println("camera displaying..");
            }
        }
    }    


 public void showVideo(URL mediaURL){
        Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true );

        try{
            //create a player to play the media specified in the URL
            Player mediaPlayer = Manager.createRealizedPlayer( mediaURL );

            //get the components for the video and the playback controls
            Component video = mediaPlayer.getVisualComponent();
            Component controls = mediaPlayer.getControlPanelComponent();

            if ( video != null )
                add( video, BorderLayout.CENTER ); //add video component
            if ( controls != null )
                add( controls, BorderLayout.SOUTH ); //add controls

                mediaPlayer.start(); //start playing the media clip
        } //end try
        catch ( NoPlayerException noPlayerException ){
            JOptionPane.showMessageDialog(null, "No media player found");
        } //end catch
        catch (CannotRealizeException ex){
            JOptionPane.showMessageDialog(null, "Could not realize media player.");
        } //end catch
        catch (IOException iOException ){
            JOptionPane.showMessageDialog(null, "Error reading from the source.");
        } //end catch
    }

请指导我。

谢谢。
