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。

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

    <dependency>
        <groupid>e-iceblue</groupid>
        <artifactid>spire.presentation.free</artifactid>
        <version>3.9.0</version>
    </dependency>

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);
    }
}
