java PPT转视频代码

以下是使用Java代码将PPT转换为视频的示例：

import com.sun.media.jmc.MediaProvider;
import com.sun.media.jmc.MediaProviderHint;
import com.sun.media.jmc.cdi.CDIServiceProvider;
import com.sun.media.jmc.control.*;
import com.sun.media.jmc.ui.*;
import java.io.*;
import javax.media.*;
import javax.media.format.*;
import javax.media.protocol.*;
import javax.media.protocol.DataSource;

public class PptToVideoConverter {
  
  public static void main(String[] args) throws Exception {

    // Specify the input PPT file path
    String inputFile = "sample.ppt";
    
    // Specify the output video file path
    String outputFile = "output.avi";

    // Create a data source for the input PPT file
    DataSource dataSource = Manager.createDataSource(new File(inputFile).toURI().toURL());
    
    // Configure the media player
    MediaLocator mediaLocator = new MediaLocator("vfw://0");
    Player player = Manager.createRealizedPlayer(mediaLocator);
    player.start();
    
    // Get the media player's output data source
    DataSource outputDataSource = player.getDataSource();
    
    // Create a processor for the output data source
    Processor processor = Manager.createProcessor(outputDataSource);
    processor.configure();
    while (processor.getState() != Processor.Configured) {
      Thread.sleep(100);
    }
    
    // Set the format of the output video
    Format outputFormat = new VideoFormat(VideoFormat.MPEG);
    TrackControl trackControl = processor.getTrackControls()[0];
    trackControl.setFormat(outputFormat);
    processor.realize();
    while (processor.getState() != Processor.Realized) {
      Thread.sleep(100);
    }
    
    // Create a media writer for the output video
    MediaProvider mediaProvider = new CDIServiceProvider().getMediaProvider(MediaProviderHint.VIDEO);
    MediaWriter mediaWriter = mediaProvider.getMediaWriter(outputFormat, new File(outputFile).toURI().toURL(), null);
    mediaWriter.open();
    
    // Start the media writer and processor
    processor.start();
    mediaWriter.start();
    while (processor.getState() != Processor.Started) {
      Thread.sleep(100);
    }
    
    // Wait for the end of the media
    while (processor.getState() != Processor.Prefetched) {
      Thread.sleep(100);
    }
    processor.stop();
    mediaWriter.stop();
    mediaWriter.close();
    
    // Cleanup
    processor.deallocate();
    player.stop();
    player.deallocate();
    
    System.out.println("PPT to video conversion completed successfully!");

  }

}
