Insert or Extract Videos in PowerPoint in Java

Inserting a video in PowerPoint is one way to enhance your presentations. It will make your document more appealing to your audience. This article will share how to insert videos in PowerPoint or extract videos from PowerPoint in Java using a free API.

Java Library for Processing PowerPoint Presentations

To insert or extract videos from PowerPoint presentations, we will need to use the free Java library — Free Spire.Presentation for Java.

Below are two methods to install it.
● Download the free API and unzip it, and then we can maually import the Spire.Presentation.jar to our projects as dependency.

● Install from maven repository by adding the following dependency to your pom.xml:

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <name>e-iceblue</name>
        <url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>
    </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.presentation.free</artifactId>
        <version>5.1.0</version>
    </dependency>
</dependencies>

Java: Insert a Video into a PowerPoint Presentation

Free Spire.Presentation for Java offers the ISlide.getShapes().appendVideoMedia(String, Rectangle2D) method to insert a video into a slide. The following is the code sample to insert video:

import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;

import java.awt.*;
import java.awt.geom.Rectangle2D;

public class InsertVideo {
    public static void main(String []args) throws Exception {
        //Create a Presentation instance
        Presentation presentation = new Presentation();
        //Load a PowerPoint document
        presentation.loadFromFile("windmills.pptx");

        //Get the first slide
        ISlide slide = presentation.getSlides().get(0);

        //Add description text
        Rectangle2D.Double rec_title = new Rectangle2D.Double(150, 360, 160, 50);
        IAutoShape shape_title = slide.getShapes().appendShape(ShapeType.RECTANGLE, rec_title);
        shape_title.getLine().setFillType(FillFormatType.NONE);
        shape_title.getFill().setFillType(FillFormatType.NONE);
        ParagraphEx para_title = new ParagraphEx();
        para_title.setText("Video:");
        para_title.setAlignment(TextAlignmentType.CENTER);
        para_title.getTextRanges().get(0).setLatinFont(new TextFont("Arial Black"));
        para_title.getTextRanges().get(0).setFontHeight(32);
        para_title.getTextRanges().get(0).isBold(TriState.TRUE);
        para_title.getTextRanges().get(0).getFill().setFillType(FillFormatType.SOLID);
        para_title.getTextRanges().get(0).getFill().getSolidColor().setColor(Color.gray);
        shape_title.getTextFrame().getParagraphs().append(para_title);

        //Add a video to the first slide
        Rectangle2D.Double videoRect = new Rectangle2D.Double(presentation.getSlideSize().getSize().getWidth() / 2 - 120, 310, 260, 180);
        IVideo video = slide.getShapes().appendVideoMedia("windmill.mp4", videoRect);
        //Set a thumbnail image for the video
        video.getPictureFill().getPicture().setUrl("video.png");

        //Save the result document
        presentation.saveToFile("InsertVideo.pptx", FileFormat.PPTX_2013);
    }
}

Output:

Java: Extract Videos from a PowerPoint Presentation

To extract the existing videos, you can first find the video shapes, and then save the videos to disk using IVideo.getEmbeddedVideoData().saveToFile() method. The following is the code sample to extract video:

import com.spire.presentation.*;

public class ExtractVideo {
    public static void main(String []args) throws Exception {
        //Create a Presentation instance
        Presentation presentation = new Presentation();
        //Load a PowerPoint document
        presentation.loadFromFile("InsertVideo.pptx");

        int i = 0;
        //Specify the output file path
        String videoPath = String.format("Videos/Video{0}.mp4", i);

        //Loop through all slides in the document
        for (Object slideObj : presentation.getSlides()) {
            ISlide slide = (ISlide) slideObj;
            //Loop through all shapes on each slide
            for (Object shapeObj : slide.getShapes()) {
                IShape shape = (IShape) shapeObj;
                //Check if the shape is of IVideo type
                if (shape instanceof IVideo) {
                    //Save the video to the specified path
                    ((IVideo) shape).getEmbeddedVideoData().saveToFile(videoPath);
                    i++;
                }
            }
        }
    }
}

Output:
