Insert Video Thumbnail when Using AddVideoFrame Method in Java

Hello,

when inserting a video through addVideoFrame (using JAVA) a media player is inserted (as is written in the doc). But I would like to have the first frame of the video visible before the movie starts, just as it works when inserting a video in PowerPoint itself… Is there any way to do this?

I tried to work with the PlaceHolder, but got a NullPointerException on the getFillFormat(), so I wasn’t able to insert an image into it. Am I missing something?

Regards,

Aart Jan

@mudassir.fayyaz Is this feature supported in Aspose.Slides for .NET? I’m currently using version 18.9.

@suzify,
With Aspose.Slides for .NET, you cannot set the first frame from a video as an image to be visible before the video starts but you can set any image instead. If you extract the first frame from the video using a third-party library, you will be able to use it.

using (Presentation presentation = new Presentation())
{
    ISlide firstSlide = presentation.Slides[0];

    using (Stream videoStream = new FileStream("video.mp4", FileMode.Open, FileAccess.Read))
    using (Stream imageStream = new FileStream("image.png", FileMode.Open, FileAccess.Read))
    {
        // Add the video to the presentation resources.
        IVideo video = presentation.Videos.AddVideo(videoStream);

        // Add the image to the presentation resources.
        IPPImage image = presentation.Images.AddImage(imageStream);

        // Add the video to the first slide.
        IVideoFrame videoFrame = firstSlide.Shapes.AddVideoFrame(20, 20, 300, 200, video);

        // Set the image to be visible before the video starts.
        videoFrame.PictureFormat.Picture.Image = image;
    }

    presentation.Save("output.pptx", SaveFormat.Pptx);
}
