Insert a Video into a PowerPoint Presentation in Java
By inserting a video into your presentation, you can share the video with your audience instantly without having to look for it on your computer while presenting. The following steps demonstrate how to insert a video into a PowerPoint presentation:
- Create an instance of the Presentation class.
- Load a PowerPoint document using Presentation.loadFromFile() method.
- Get a specific slide by its index using Presentation.getSlides().get(int) method.
- Create an instance of the Rectangle2D class.
- Add a video to the slide using ISlide.getShapes().appendVideoMedia(String, Rectangle2D) method.
- Set a thumbnail image for the video using IVideo.getPictureFill().getPicture().setUrl() method.
- Save the result document using Presentation.SaveToFile() method.
- Java
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("Input.pptx");
//Get the first slide
ISlide slide = presentation.getSlides().get(0);
//Add description text
Rectangle2D.Double rec_title = new Rectangle2D.Double(50, 280, 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("Myriad Pro Light"));
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 - 125, 240, 240, 130);
IVideo video = slide.getShapes().appendVideoMedia("Video.mp4", videoRect);
//Set a thumbnail image for the video
video.getPictureFill().getPicture().setUrl("https://cdn.e-iceblue.com/Picture.png");
//Save the result document
presentation.saveToFile("InsertVideo.pptx", FileFormat.PPTX_2013);
}
}
Replace a Video in a PowerPoint Presentation in Java
If you think an existing video cannot support your statements well, you can replace it with another suitable one. The following steps demonstrate how to replace an existing video with another video in a PowerPoint presentation:
- Create an instance of the Presentation class.
- Load a PowerPoint document using Presentation.loadFromFile() method.
- Get a specific slide by its index using Presentation.getSlides().get(int) method.
- Load a video into a byte array.
- Add the loaded video to the video collection of the document using Presentation.getVideos().append(byte[]) method.
- Loop through all shapes on the slide and find the video shape.
- Replace the original video with the loaded video using IVideo.setEmbeddedVideoData() method. Then change the thumbnail image of the video using IVideo.getPictureFill().getPicture().setUrl() method.
- Save the result document using Presentation.saveToFile() method.
- Java
import com.spire.presentation.*;
import java.io.File;
import java.io.FileInputStream;
public class ReplaceVideo {
public static void main(String []args) throws Exception {
//Create a Presentation instance
Presentation ppt = new Presentation();
//Load a PowerPoint document
ppt.loadFromFile("InsertVideo.pptx");
//Get the first slide
ISlide iSlide = ppt.getSlides().get(0);
//Load a video into a byte array
File file = new File("NewVideo.mp4");
FileInputStream fileInputStream = new FileInputStream(file);
byte[] data = new byte[(int) file.length()];
fileInputStream.read(data);
//Add the loaded video to the video collection of the document
VideoData videoData = ppt.getVideos().append(data);
//Loop through all shapes on the first slide
for (Object shape : iSlide.getShapes()) {
//Check if the current shape is of IVideo type
if (shape instanceof IVideo) {
IVideo video = (IVideo) shape;
//Replace the original video with the loaded video
video.setEmbeddedVideoData(videoData);
//Change the thumbnail image of the video
video.getPictureFill().getPicture().setUrl("https://cdn.e-iceblue.com/Picture1.png");
}
}
//Save the result document
ppt.saveToFile("ReplaceVideo.pptx", FileFormat.PPTX_2013);
}
}
Extract Videos from a PowerPoint Presentation in Java
If you like the videos in a PowerPoint presentation and want to use them in other places, you can extract and save them to your disk. The following steps demonstrate how to extract videos from a PowerPoint presentation:
- Create an instance of the Presentation class.
- Load a PowerPoint document using Presentation.LoadFromFile() method.
- Loop through all slides in the document.
- Loop through all shapes on each slide.
- Find the video shapes, then save the videos to disk using IVideo.getEmbeddedVideoData().saveToFile() method.
- Java
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("ReplaceVideo.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++;
}
}
}
}
}
