How can i create a thumbnail from a video binary (bytes[])?

I do not have access to the directories, so i can't save the file and the example that I can see (using ffmpeg) to create a thumbnail is from a path.

Is there another way to do it?

c#

Assuming, sampleBytes is our byte[] :

using (MemoryStream ms = new MemoryStream(sampleBytes))
{
    Bitmap thumb = new Bitmap(100, 100);
    using (Image bmp = Image.FromStream(ms))
    {
        using (Graphics g = Graphics.FromImage(thumb))
        { 
            g.InterpolationMode = InterpolationMode.HighQualityBicubic;
            g.CompositingQuality = CompositingQuality.HighQuality;
            g.SmoothingMode = SmoothingMode.HighQuality;
            g.DrawImage(bmp, 0, 0, 100, 100);
        }
    }
    // this can show the result
    picBoxOut.Image = thumb;
}
