Get duration from a video/audio file in a Web Application (asp.net core)

This question is about a asp.net WEB Application and not about .net windows application. In my application I am uploading video files (mp4) using asp.net core.

I need to get metadata from this video file, but for now I am focusing on the duration of this video file.

I have created the form and in my controller I am successfully receiving an IFormFile file object. I can find the size the file by just calling the .length method ( file.Length ) but I am really struggling to get the exact date and especially the duration of this object.

How can I determine the exact date and the duration of this object?

This is my code:

    public async Task UploadVideos(IList<IFormFile> files)
    {
        long size = files.Sum(f => f.Length);
        Console.WriteLine("The size of all the selected files is:"+size);

        Console.WriteLine("the file name is" + files[0].FileName);


        string type = files[0].ContentType;
        if (type.Equals("video/mp4"))
        {
            Console.WriteLine("Indeed a mp4 format");
        }

    }

Sorry for the late reply, here is how you would go about getting the duration of a video after it is uploaded,

You can use NReco,the provided link has a nice little example on how to get the info of a video, 

var ffProbe = new NReco.VideoInfo.FFProbe();
var videoInfo = ffProbe.GetMediaInfo(pathToVideoFile);
Console.WriteLine(videoInfo.FormatName);
Console.WriteLine(videoInfo.Duration);

The the only issue being licensing for commercial use.

The other one you can try is the mediatoolkit, I have used this before and it works great, especially for the functionality that you are looking for, a simple usage would be along the lines of 

var inputFile = new MediaFile { Filename = video_name };

        using (var engine = new Engine())
        {
            engine.GetMetadata(inputFile);   
       }

A sample image shows the output of calling the getmetadata method, Video Data.

MediaToolkit uses an MIT license

All the above are wrappers of the c++ FFmpeg Library
