ppt链接视频怎么弄 关于PPT中的视频

PowerPoint 演示文稿是我们常用的办公软件之一。为了能够更加全面细致地展示要说明的内容，视频不失为一种很好的展示方式。本文将使用Java代码来演示如何插入视频到PowerPoint幻灯片，同时也将介绍提取视频以及设置视频播放模式的方法。

使用工具：Free Spire.Presentation for Java

测试环境：JDK 1.8.0、Intellij IDEA 2019

Jar包导入：

方式一：在E-iceblue中文官网上下载产品包，解压后在lib文件夹下找到Spire.Presentation.jar，然后手动将其导入IDEA。

方式二：在IDEA中创建Maven项目，然后在pom.xml下键入以下代码，最后点击“Import Changes”即可。

代码示例

示例一 插入视频到PowerPoint幻灯片

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 {
        //加载PowerPoint示例文档
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\Users\Test1\Desktop\Sample.pptx");

        //获取第一张幻灯片
        ISlide slide = presentation.getSlides().get(0);

        //插入视频到第一张幻灯片并设置封面图片
        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));

        //保存结果文档
        presentation.saveToFile("output/InsertVideo.pptx", FileFormat.PPTX_2010);
        presentation.dispose();
    }
}

效果图：

示例二 提取PowerPoint幻灯片中已有的视频

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 {
        //实例化一个ppt对象并加载示例文档
        Presentation ppt = new Presentation();
        ppt.loadFromFile("C:\Users\Test1\Desktop\InsertVideo.pptx");

        //获取第一张幻灯片
        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)) {
                //保存视频
                video = (IVideo) shape;
                video.getEmbeddedVideoData().saveToFile("output/ExtractVideo"+i+".mp4");
            }
        }
    }
}

示例三 设置视频播放模式

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 {
       //实例化一个presentation对象并加载示例文档
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\Users\Test1\Desktop\InsertVideo.pptx");

        //获取第一张幻灯片
        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;

                //设置视频的播放模式为自动播放
                //video.setPlayMode(VideoPlayMode.AUTO);

                //设置视频的播放模式为单击时播放
                video.setPlayMode(VideoPlayMode.ON_CLICK);
            }
        }
        //保存PPT文档
        presentation.saveToFile("output/单击播放.pptx", FileFormat.PPTX_2010);
    }
}

设置效果：
