Aspose.PDF does not detect embedded video file

Aspose.PDF Product Family

Hi Andrey
Just started to use Aspose.PDF with that file and video is not detected:

code:

Aspose.Pdf.Document doc = new Aspose.Pdf.Document(pdf);
var embedded_files = doc.EmbeddedFiles;

embedded_files is empty !

Is this normal ?

Thank you

@pcaillol,

This is because there are no videos attached:

4

I confirm that the video is embedded / not attached and playing as following:

Aspose.PDF shows “EmbeddedFiles” property so what is the explanation ?

Thanks.

5

@pcaillol,

I see. Let me review it because I initially thought of an attachment.

6

As shows the video, there is no attachment detected though the video is obviously embedded.

@pcaillol,

I will create a ticket for the dev team then.

8

Another thread ? ticket number ?

Thank you.

When viewing the attached file in Acrobat Pro, you can see that there are no embedded files in it, but there is a RichMedia annotation.
You can make sure that it exists and access this annotation using the API as follows:

var doc = new Document(myDir + "ReadingEmbbededFiles_input.pdf");
var annotation = doc.Pages[1].Annotations[1];
Console.WriteLine($"annotation.AnnotationType: {annotation.AnnotationType}");

The PageInfo properties Width, Height, IsLandscape used in the attached code snippet are intended for using a pdf file generator and are not filled in when reading file.

To reliably determine the orientation of the page, use the MediaBox property of the page.
If the width there is less (or equal) than the height, the page has a portrait orientation, otherwise landscape.

Page sizes can be determined using UserUnit (if specified) and MediaBox.Width, MediaBox.Height.

using (Document document = new Document(fileName))
{
    foreach (Page page in document.Pages)
    {
        var pageMediaBox = page.MediaBox;
        var isLandscape = pageMediaBox.Width > pageMediaBox.Height; // reliably determined.

        double userUnit = 72.0; // pixels per inch
        if (page.EnginePage.PageInformation.UserUnit != null)
        {
            userUnit = 72.0 * page.EnginePage.PageInformation.UserUnit.ToDouble();
        }

        double k = 25.4 / userUnit;
        var pageWidth = k * pageMediaBox.Width;
        var pageHeight = k * pageMediaBox.Height;

        Console.WriteLine("Height: " + pageHeight + ", Width: " + pageWidth + ", Landscape: " + isLandscape);
    }
}

The above tickets are currently under the phase of the investigation and the investigation against rest of the tickets has not been started sadly yet. However, we will surely inform you as soon as we make some progress towards resolution of the all logged tickets. Please be patient and spare us some time.

We are sorry for the inconvenience.
