hi

seems extracting quite big video (450mo) not working or taking huge time to succeed (not observed !)
whereas works with 18mo video.

win11/.net 4.8/aspose.pdf 23.3.0

pdf:

code:
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(pdf);
var fileSpec = embedded_vid_files[0];
using (FileStream outputFileStream = new FileStream(vid_path, FileMode.Create, FileAccess.Write, FileShare.Read))
{
fileSpec.StreamContents.CopyTo(outputFileStream);
}

can you help please ?

thanks.

@pcaillol,

I am still testing this, but due to how this works, this test will take more time. Just letting you know I am working on it.

@pcaillol,

It took a while but it actually finished:

Basically you will need to wait for the file to be saved on your storage. It is not a bug. The biggeest the file, the longest it will take.

This is the code I used:

private void Logic()
{
    Document doc = new Document($"{PartialPath}_input.pdf");

    Console.WriteLine("Starting...");
    using (FileStream outputFileStream = new FileStream($"{PartialPath}_output.mp4", FileMode.Create, FileAccess.Write, FileShare.Read))
    {
        var file1 = doc.EmbeddedFiles[1];
        file1.StreamContents.CopyTo(outputFileStream);
    }
    Console.WriteLine("Finished...");
    Console.ReadKey();
}

Any way to speed up a lot ?

Thanks.

@pcaillol,

Sadly I do not know a way to speed up the process.

hi

Could you please dig further informations close to dev team about a way to speed up the process because this is absolutely critical, do you understand ?

thanks

@pcaillol,

I can create a task instead of a bug, but that will not be a priority at all. Just letting you know. Also, you can try creating an app embedding a 450 MB file and then download it using the same method. It will take some time to do that too. Just letting you know.
