PowerPoint 演示文稿是我們常用的辦公軟件之一。為了能夠更加全面細緻地展示要說明的內容，視頻不失為一種很好的展示方式。本文將使用Java代碼來演示如何插入視頻到PowerPoint幻燈片，同時也將介紹提取視頻以及設置視頻播放模式的方法。

使用工具：Free Spire.Presentation for Java

測試環境：JDK 1.8.0、Intellij IDEA 2019

Jar包導入：

方式一：在E-iceblue中文官網上下載產品包，解壓後在lib文件夾下找到Spire.Presentation.jar，然後手動將其導入IDEA。

方式二：在IDEA中創建Maven項目，然後在pom.xml下鍵入以下代碼，最後點擊“Import Changes”即可。

        <repository>
            <id>com.e-iceblue</id>
            <url>http://repo.e-iceblue.cn/repository/maven-public/</url>
        </repository>

        <groupId>e-iceblue</groupId>
        <artifactId>spire.presentation.free</artifactId>
        <version>3.9.0</version>
    </dependency>

代碼示例

示例一 插入視頻到PowerPoint幻燈片

import com.spire.presentation.*;
import javax.imageio.ImageIO;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import java.io.File;

public class InsertVideo {
    public static void main(String[] args) throws Exception {
        //加載PowerPoint示例文檔
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\Users\Test1\Desktop\Sample.pptx");

        //獲取第一張幻燈片
        ISlide slide = presentation.getSlides().get(0);

        //插入視頻到第一張幻燈片並設置封面圖片
        Rectangle2D.Double videoRect = new Rectangle2D.Double(150, 120, 400, 225);
        IVideo video = presentation.getSlides().get(0).getShapes().appendVideoMedia((new java.io.File("C:\Users\Test1\Desktop\video.mp4")).getAbsolutePath(), videoRect);
        BufferedImage coverImage = ImageIO.read( new File("C:\Users\Test1\Desktop\image.png"));
        video.getPictureFill().getPicture().setEmbedImage(presentation.getImages().append(coverImage));

        //保存結果文檔
        presentation.saveToFile("output/InsertVideo.pptx", FileFormat.PPTX_2010);
        presentation.dispose();
    }
}

效果圖：

示例二 提取PowerPoint幻燈片中已有的視頻

import com.spire.presentation.IShape;
import com.spire.presentation.ISlide;
import com.spire.presentation.IVideo;
import com.spire.presentation.Presentation;

public class ExtractVideo {
    public static void main(String[] args) throws Exception {
        //實例化一個ppt對象並加載示例文檔
        Presentation ppt = new Presentation();
        ppt.loadFromFile("C:\Users\Test1\Desktop\InsertVideo.pptx");

        //獲取第一張幻燈片
        ISlide slide = ppt.getSlides().get(0);

        IVideo video = null;

        for(int i = 0; i< slide.getShapes().getCount(); i++)
        {
            IShape shape = slide.getShapes().get(i);
            if ((shape instanceof IVideo)) {
                //保存視頻
                video = (IVideo) shape;
                video.getEmbeddedVideoData().saveToFile("output/ExtractVideo"+i+".mp4");
            }
        }
    }
}

示例三 設置視頻播放模式

import com.spire.presentation.FileFormat;
import com.spire.presentation.IShape;
import com.spire.presentation.ISlide;
import com.spire.presentation.IVideo;
import com.spire.presentation.Presentation;
import com.spire.presentation.VideoPlayMode;

public class PlayType {
    public static void main(String[] args) throws Exception {
       //實例化一個presentation對象並加載示例文檔
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\Users\Test1\Desktop\InsertVideo.pptx");

        //獲取第一張幻燈片
        ISlide slide = presentation.getSlides().get(0);

        IVideo video = null;
        for(int i = 0; i< slide.getShapes().getCount(); i++)
        {
            IShape shape = slide.getShapes().get(i);
            if ((shape instanceof IVideo)) {
                video = (IVideo) shape;

                //設置視頻的播放模式為自動播放
                //video.setPlayMode(VideoPlayMode.AUTO);

                //設置視頻的播放模式為單擊時播放
                video.setPlayMode(VideoPlayMode.ON_CLICK);
            }
        }
        //保存PPT文檔
        presentation.saveToFile("output/單擊播放.pptx", FileFormat.PPTX_2010);
    }
}

設置效果：
