Java

Overview

1- MainThread starts ServerThread
2- ServerThread start ClientThread
3- ClientThread has a loop. In this loop, I read next image and pass it to MovieWriter (which writes it to DataOutputStream of clientSocket) with a delay of 50ms



class ClientThread extends Thread
{
  @Overrie
  public void run()
  {
    OutputStream outStream = clientSocket.getOutputStream(); // clientSocket = class variable
    DataOutputStream dataOutStream = new DataOutputStream(outStream);

    MovieWriter mv = new MovieWriter(dataOutStream);
    mv.WriterHttpHeader();
    while(true)
    {
      Thread.sleep(50);
      ByteArrayOutputStream image = ReadImage.GetNext(); // 'ReadImage' is static class which returns the next image
      mv.WriteNextImage(image.toByteArray());
    }
  }  
}

class MovieWriter
{
  public MovieWriter(DataOutputStream)
  {
    // set class variable
  }

  public void WriterHttpHeader()
  {
    String header = "HTTP/1.1 200 OK \r\n Content-Type: multipart/x-mixed-replace; boundary=--boundary";
    dataOutputStream.write(GetBytes(header)); // dataOutputStream = class variable; GetBytes() return bytes of header
  }

  public void WriteNextImage(byte[] data)
  {
    try
    {
      String response = "Content-Type: image/jpg \r\n" + "Content-Length: " + String.ValueOf(data.length);
      dataOutputStream.write(GetBytes(response)); // first write response header
      dataOutputStream.write(data);      // then write image data
    } catch(Exception ex) {
      ex.printStackTrace();
    }
  }
  
}
