Video Frame

Create Embedded Video Frame

Developers can also add and play video files in slides to enrich their presentations. Aspose.Slides for Java supports adding Video Frames to the slides that make it possible for developers to add videos to their presentations. This topic will help developers to follow the simple steps with examples for adding video frames in their slides. To add a Video Frame in a slide using Aspose.Slides for Java, please follow the steps below:

1. Create an instance of Presentation class.
2. Obtain the reference of a slide by using its Index.
3. Add the Video Frame (containing the video file name) into the slide.
4. Write the modified presentation as a PPTX file.

In the example below, we added a Video Frame to the slide.

// Instantiate Presentation class that represents the PPTX
Presentation pres = new Presentation();
try {
    // Get the first slide
    ISlide sld = pres.getSlides().get_Item(0);
    
    // Embed video inside presentation
    IVideo vid = pres.getVideos().addVideo(new FileInputStream(new File("Wildlife.mp4")));

    // Add Video Frame
    IVideoFrame vf = sld.getShapes().addVideoFrame(50, 150, 300, 350, vid);

    // Set video to Video Frame
    vf.setEmbeddedVideo(vid);

    // Set Play Mode and Volume of the Video
    vf.setPlayMode(VideoPlayModePreset.Auto);
    vf.setVolume(AudioVolumeMode.Loud);

    // Write the PPTX file to disk
    pres.save("VideoFrame.pptx", SaveFormat.Pptx);
} catch (Exception e) {
} finally {
    if (pres != null) pres.dispose();
}

It is possible to add a video passing path to the video file directly into AddVideoFrame method:

Presentation pres = new Presentation();
try {
	ISlide sld = pres.getSlides().get_Item(0);
	IVideoFrame vf = sld.getShapes().addVideoFrame(50, 150, 300, 150, "video1.avi");
} finally {
	if (pres != null) pres.dispose();
}

Create Video Frame with Video from Web Source

PowerPoint 2010 and newer versions support YouTube videos. To play such videos in PowerPoint, verify that your environment meet the requirements for embedding videos from web sources.

Follow these steps:

1. Create an instance of Presentation class.
2. Obtain the reference of a slide by using its Index.
3. Add the Video Frame by passing video URL.
4. Set Image for Video Frame.
5. Save presentation as a PPTX file.

This sample code shows you how to to add a video from YouTube to your presentation using Aspose.Slides:

// Instantiate Presentation class that represents the PPTX
Presentation pres = new Presentation();
try {
    addVideoFromYouTube(pres, "Tj75Arhq5ho");
    pres.save("out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

private static void addVideoFromYouTube(Presentation pres, String videoID)
{
    // add videoFrame
    IVideoFrame videoFrame = pres.getSlides().get_Item(0).getShapes().addVideoFrame(
            10, 10, 427, 240, "https://www.youtube.com/embed/" + videoID);
    videoFrame.setPlayMode(VideoPlayModePreset.Auto);

    // load thumbnail
    String thumbnailUri = "http://img.youtube.com/vi/" + videoID + "/hqdefault.jpg";
    URL url;

    try {
        url = new URL(thumbnailUri);
        videoFrame.getPictureFormat().getPicture().setImage(pres.getImages().addImage(url.openStream()));
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Extract Video From Slide

Aspose.Slides for Java supports extracting video from the slide. In order to extract the video. Please follow the steps below:

• Load a Presentation containing a video.
• Loop through all the slides of the Presentation.
• Search for Video Frame.
• Save the Video to disk.

In the example given below, we saved the video file from a slide.

Presentation pres = new Presentation("VideoSample.pptx");
try {
    for (ISlide slide : pres.getSlides()) 
    {
        for (IShape shape : slide.getShapes()) 
        {
            if (shape instanceof VideoFrame) 
            {
                IVideoFrame vf = (IVideoFrame) shape;
                String type = vf.getEmbeddedVideo().getContentType();
                int ss = type.lastIndexOf('-');
                byte[] buffer = vf.getEmbeddedVideo().getBinaryData();

                //Get File Extension
                int charIndex = type.indexOf("/");
                type = type.substring(charIndex + 1);

                FileOutputStream fop = new FileOutputStream("testing2." + type);
                fop.write(buffer);
                fop.flush();
                fop.close();
            }
        }
    }
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}
