Yes im writing and reading from sockets.
Im using webcam-capture API for it.
Following is my code for server sending webcam. When following server thread run it opens webcam panel and show webcam live video. I write this object to client. Following is the server code :

 public void run(){
 
        if(cam!=null){
            try{
            System.out.println("Prepared to write");
            //cam= Webcam.getDefault();
 
 
            WebcamPanel pnl = new WebcamPanel(cam);
            JFrame j= new JFrame();
            j.add(pnl);
            j.setVisible(true);
            //byte[] by = (byte)cam;
            try{
                while(true){ 
                    System.out.println("Starting writing...");
               // wr = new BufferedWriter(new OutputStreamWriter(clientSocket.getOutputStream()));
                //wr.write("abc");
                //wr.write('\n');
                //wr.flush();
                    objwr= new ObjectOutputStream(clientSocket.getOutputStream());
                   //wr = new BufferedWriter(objwr);
                    objwr.writeObject(cam);
                       }
 
            }
            catch (Exception ex){
                throw new InterruptedException(ex.getMessage());
            }
            finally{
                try{
                    if(wr!=null)
                        {
                            wr.close();
                        }
                        if(objwr!=null)
                        {
                            objwr.close();
                        }
                    }
                    catch(Exception ex3){
                        throw new InterruptedException(ex3.getMessage());
                    }
            }
 
 
 
 
            //Thread.sleep(0);
            }
            catch(InterruptedException ex)
            {
                throw new RuntimeException(ex.getMessage());
            }
 
        }
 
 
 
    }

Following is the client code :

@Override
    public void run(){
        try{
 
            boolean fl=true;
            //cam.open();
            WebcamPanel pnl; 
            //JFrame j= new JFrame();
            //j.add(pnl);
            //j.setVisible(true);
 
                try{
 
                    objin= new ObjectInputStream(serverSocket.getInputStream());
                       while(true){
                           if(fl)
                           { System.out.println("Setting for 1st time");
                               cam = (Webcam)objin.readObject();
                               pnl = new WebcamPanel(cam);
                               JFrame j= new JFrame();
                               j.add(pnl);
                               j.setVisible(true);
 
                           }
                           else {
                               System.out.println("for 2nd time");
                               cam = (Webcam)objin.readObject();
 
                           }
 
 
 
 
                       }
 
                    //System.out.println("Reading video");
                    //BufferedReader rdr= new BufferedReader( new InputStreamReader(serverSocket.getInputStream()));
                    //System.out.println(rdr.readLine());
 
 
                }
                catch(Exception ex1){
                    throw new InterruptedException(ex1.getMessage());
                }
 
                finally{
                    try{
                        if(objin!=null)
                        {
                            objin.close();
                        }
                    }
                    catch(Exception ex3){
                        throw new InterruptedException(ex3.getMessage());
                    }
 
                }
 
 
        }
        catch(InterruptedException ex){
            throw new RuntimeException(ex.getMessage());
        }
 
 
    }

And im getting this error while reading from client side

Exception in thread "Thread-0" java.lang.RuntimeException: writing aborted; java.io.NotSerializableException: com.github.sarxos.webcam.Webcam
at VideoClient.TCameraReader.run(TCameraReader.java:9 3)

and in server side :
Exception in thread "Thread-3" java.lang.RuntimeException: com.github.sarxos.webcam.Webcam
at VideoServer.TCameraWriter.run(TCameraWriter.java:9 0)

You haven't posted the appropriate code for anyone to say that the object you are writing is Serializable.

In this API there is not any thing written for sending in streams.
I used cam object which is object of Webcam class which is used in API
Can you please tell me any other API which can be used for sending cam via sockets.

Thanks
