How to capture images using web camera in ASP.NET 4.5.

Introduction

I was working for a project to develop a web conferencing application. I accepted the project and started to work on it. My first effort was to integrate a web cam into my application. I searched about it and found that it’s very simple. I have been very busy doing this project. Here is my first and small effort which makes my mind clear about the completion of this project.

Requirements

  1. Latest Flash player
  2. Web camera

The solution

You need to:

  1. Copy the “WebcamResources” into your new application.
  2. Add the following code in to your Default.aspx page:
  3. <object width="450" height="200"
      param name="movie1" value="WebcamResources/save_picture.swf"
      embed src="WebcamResources/save_picture.swf" width="450" 
      height="200" >
    </object>

    This code will place your Flash object into your web page, used to capture the images from the web cam.

  4. Add one more page there with the name ImageConversions.aspx.
  5. Add the following code into ImageConversion.aspx at the page load event:
  6. string str_Photo = Request.Form["image_Data"]; //Get the image from flash file
    byte[] photo = Convert.FromBase64String(str_Photo);
    FileStream f_s = new FileStream("C:\\capture.jpg", FileMode.OpenOrCreate, FileAccess.Write);
    BinaryWriter b_r = new BinaryWriter(f_s);
    b_r.Write(photo);
    b_r.Flush();
    b_r.Close();
    f_s.Close();

The above code will convert the bytes to an image and will save the image in the c drive.

Enjoy!
