• How to show Images from a video as preview for playlist

  1er février 2017, par Guruprasad Rao

  You guys Have seen Youtube right. There while you are watching a video, You will also get related videos preview alongwith link. So how we can get it from video itself.. Is it possible to do so.. I am able to get the url from database and display it.. and when the link is clicked it will be played in a jquery player.. So before that a preview of that or you can say playlist of that will be available for user.

  I have updated my code with a link I found.. But still I am not able to get the Image from Video.. Is there anything wrong in my code.. Please correct me if I am wrong..

  Below is my front end code :

  <form runat="server">
  
      <div runat="server" style="height:100%;width:100%">
  
          <div>Latest Videos</div>
  
  
  
      </div>
  
  
  
      </form>

  and I am adding all my video links from backend on page load as shown below :

     try
  
      {
  
          con.Open();
  
          com = new SqlCommand("Select videourl, videoname from video order by [vid] desc",con);
  
          DbDataReader dr = com.ExecuteReader();
  
          DataTable dt = new DataTable();
  
  
  
          if (dr.HasRows)
  
          {
  
  
  
              int i = 0;
  
              dt.Load(dr);
  
              int rows = dt.Rows.Count;
  
  
  
  
  
              for (i = 0; i < rows; i++)
  
              {
  
                  HtmlGenericControl d = new HtmlGenericControl("div");
  
                  HtmlGenericControl s = new HtmlGenericControl("span");
  
                  string[] link = new string[rows];
  
                  string[] name = new string[rows];                    
  
  
  
                  d.Attributes.Add("class", "plst");
  
                  s.Attributes.Add("class", "text");
  
                  link[i] = dt.Rows[i]["videourl"].ToString();
  
                  name[i] = dt.Rows[i]["videoname"].ToString();
  
                  string videothumb = link[i];
  
                  string svthto="**Path to save Image**";
  
                  string imgpath=GetVideoThumbnail(videothumb, svthto, 30);
  
  
  
                  sb.Append("<a i="i" href=" + " class=" + ">" + name[i] + "</a>");
  
                  s.InnerHtml = sb.ToString();
  
                  d.Controls.Add(s);
  
                  examples.Controls.Add(d);
  
                  sb.Clear();
  
  
  
  
  
              }
  
          }
  
  
  
  
  
      }
  
      catch(Exception ex)
  
      {
  
          ex.Message.ToString();
  
      }
  
  
  
  public string GetVideoThumbnail(string path, string saveThumbnailTo, int seconds)
  
  {
  
      string parameters = string.Format("-ss {0} -i {1} -f image2 -vframes 1 -y {2}", seconds, path, saveThumbnailTo);
  
      string pathToConvertor = "C:\\Program Files\\ffmpeg\\ffmpeg.exe";
  
      var processInfo = new ProcessStartInfo();
  
      processInfo.FileName = pathToConvertor;
  
      processInfo.Arguments = parameters;
  
      processInfo.CreateNoWindow = true;
  
      processInfo.UseShellExecute = false;
  
  
  
      File.Delete(saveThumbnailTo);
  
  
  
      using (var process = new Process())
  
      {
  
          process.StartInfo = processInfo;
  
          process.Start();
  
          process.WaitForExit();
  
      }
  
  
  
      if (File.Exists(saveThumbnailTo))
  
          return saveThumbnailTo;
  
      else
  
          return "File not Found";
  
  }

  and here is the image of what I am getting until now :
  

  Please note : I am not concentrating on you tube videos. I am questioning regarding the videos which I store in server side folder. So if there is any jquery technique or any sort of technique to do this then please let me know. :)
