Video

This article demonstrates how to embed video frames and set playback options using Aspose.Slides for .NET.

The checks verify embedded MP4 bytes and playback settings. Actual playback also depends on the presentation application’s codec and security support.

Download and run

Download the complete project, extract it, and open Example.sln or run:

dotnet restore Example.sln
dotnet run --project Example.csproj -- --mode evaluation

The download includes every case below, its fixture helpers and inputs. Program.cs runs all cases; use --action block-001 to run one independently. Outputs and an action report are written to the printed output directory. No previous example or working-directory setup is required. Evaluation adds a watermark and can truncate read-back text; the short fixtures still have explicit structural checks. For full text and no watermark, use --mode licensed --license PATH with your own valid license. See the setup guide for supported SDKs and native prerequisites.

Each printed CaseNN.cs file is compiled verbatim with the included Program.cs and bootstrap. Checks run before saving and after reopening the result.

Add a Video Frame

Insert an empty video frame onto a slide.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case01()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        // Add a video.
        var video = presentation.Videos.AddVideo(File.ReadAllBytes(Context.Input("video.mp4")));
        var videoFrame = slide.Shapes.AddVideoFrame(50, 50, 320, 240, video);

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-001", p =>
        {
            Context.Require(p.Slides[0].Shapes.OfType<IVideoFrame>().Single().EmbeddedVideo.BinaryData.SequenceEqual(File.ReadAllBytes(Context.Input("video.mp4"))), "AddVideo: semantic check 1 failed.");
        });
        Context.Pass("elements/video/block-001", "AddVideo", "save-reopen-structure");
    }
}

Access a Video Frame

Retrieve the first video frame added to a slide.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case02()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        var video = presentation.Videos.AddVideo(File.ReadAllBytes(Context.Input("video.mp4")));
        var videoFrame = slide.Shapes.AddVideoFrame(50, 50, 320, 240, video);

        // Access the first video frame on the slide.
        var firstVideo = slide.Shapes.OfType<IVideoFrame>().First();

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-002", p =>
        {
            Context.Require(p.Slides[0].Shapes.OfType<IVideoFrame>().Single().EmbeddedVideo.BinaryData.Length > 100, "AccessVideo: semantic check 1 failed.");
        });
        Context.Pass("elements/video/block-002", "AccessVideo", "save-reopen-structure");
    }
}

Remove a Video Frame

Delete a video frame from the slide.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case03()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        var video = presentation.Videos.AddVideo(File.ReadAllBytes(Context.Input("video.mp4")));
        var videoFrame = slide.Shapes.AddVideoFrame(50, 50, 320, 240, video);

        // Remove the video frame.
        slide.Shapes.Remove(videoFrame);

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-003", p =>
        {
            Context.Require(!p.Slides[0].Shapes.OfType<IVideoFrame>().Any(), "RemoveVideo: semantic check 1 failed.");
        });
        Context.Pass("elements/video/block-003", "RemoveVideo", "save-reopen-structure");
    }
}

Set Video Playback

Configure the video to play automatically when the slide is displayed.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case04()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        var video = presentation.Videos.AddVideo(File.ReadAllBytes(Context.Input("video.mp4")));
        var videoFrame = slide.Shapes.AddVideoFrame(50, 50, 320, 240, video);

        // Configure the video to play automatically.
        videoFrame.PlayMode = VideoPlayModePreset.Auto;

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-004", p =>
        {
            Context.Require(p.Slides[0].Shapes.OfType<IVideoFrame>().Single().PlayMode == VideoPlayModePreset.Auto, "SetVideoPlayback: semantic check 1 failed.");
        });
        Context.Pass("elements/video/block-004", "SetVideoPlayback", "save-reopen-structure");
    }
}
