I am trying to download you tube video using c# code but i am not getting proper code. I have searched many link but din't get any proper links and code.

I want to download the you tube video in my local folder with c# code. I have tried one link but that code just getting null video in my local folder so any one have the idea how can do that.

Below is the code i have tried so far.

var VedioUrl = "https://www.youtube.com/embed/" + objYouTube.VideoID + ".mp4";

WebRequest MyRequest = HttpWebRequest.Create(VedioUrl);
WebResponse MyResponse = MyRequest.GetResponse();
string RealURL = MyResponse.ResponseUri.ToString();
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(RealURL);
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
Stream receiveStream = myHttpWebResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
StreamReader readStream = new StreamReader(receiveStream, encode);
StreamWriter writer = new StreamWriter(Server.MapPath("~/youtube/" + objYouTube.VideoID + ".mp4"), true);
writer.Write(readStream.ReadToEnd());
writer.Close();

so here is my video url which i am trying to download : "https://www.youtube.com/embed/UCsiNPbLbwZk43FOCRrdKBlA.mp4"

after install the "libvideo" on NuGet package manager console in visual studio.

and download ffmpeg for merge audio and video for best output .

follow this code :

using System;
using System.Diagnostics;
using System.IO;
using System.Net;
using VideoLibrary;

namespace you_tube_download
{
    class Program

            string url = Console.ReadLine();
            string information = "";
            var videos = YouTube.Default.GetAllVideos(url);
            int hightaudio = 1;
            int hightvideo = 1;
            Console.WriteLine("\nlist all format \n");
            foreach (var item in videos)//write all file on this url
             {
                Console.WriteLine(item.Resolution+","+item.Format + "," + item.AudioFormat + "," + item.AudioBitrate + "," + item.ContentLength + "," + item.AdaptiveKind);
                if (item.AdaptiveKind.ToString() == "Audio" && item.AudioBitrate > hightaudio)
                {
