In this article we will see, how we can cut the first frame of our video and save it as a jpg image using ffmpeg software. To download the ffmpeg software please go to the following link:

Step 1: Create a .Net application.

Step 2: Include the downloaded ffmpeg.exe file in your project.

Step 3: Take the following controls in your aspx page:

<asp:FileUpload ID="fileUpload" runat="server" />
<asp:Button ID="btnSubmit" runat="server" Text="Upload" OnClick="btnSubmit&#95;Click"/>

Note:-> To upload and submit the video.

Step 4: Now we have to call the exec() method of the ffmpeg software. The exec() method takes the following parameters: "The url of the uploaded video","The path where the image has to be stored along with the image name" and "The resolution". Inorder to acheive this write the following code onclick of the Submit button in code behind as follows:

protected void btnSubmit_Click(object sender, EventArgs e)
        {
          if (fileUpload.HasFile)
          {
            exec("http://localhost:52137/" + fileUpload.FileName, Server.MapPath("~/Images/thumb.jpg") ,"640x480");

          }
        }

Note:-> You can see that the parameters we have passed above in the code are the url of the uploaded video on the local server, The path where the image will be stored along with the image name and the resolution.

Step 5: Now write the exec() method as follows:

public void exec(string input, string output, string parametri)
{
  ffmpeg = new Process();
  ffmpeg.StartInfo.Arguments = " -i " + input + (parametri != null ? " " + parametri : "") + " " + output;
  ffmpeg.StartInfo.FileName = Server.MapPath("~/ffmpeg.exe"); //Path to the ffmpeg.exe 
  ffmpeg.StartInfo.UseShellExecute = false;
  ffmpeg.StartInfo.RedirectStandardOutput = true;
  ffmpeg.StartInfo.RedirectStandardError = true;
  ffmpeg.StartInfo.CreateNoWindow = true;
  ffmpeg.Start();
  ffmpeg.WaitForExit();
  ffmpeg.Close();
}

Step 6: Now run the code, you will get the image of the first frame of the video in the given path.
