MediaRecoder ParcelFileDescriptor

I try to record camera image in other pc storage.
I use network for transfer data.

I refered this site.

I prepared ParcelFileDescriptor and socket.

ParcelFileDescriptor pfd = null;
Socket  socket = null;

I set for network setting.
192.168.1.2 is my pc ip address.

String hostname = "192.168.1.2";
int port = 5000;

I try to create socket

try {
 socket = new Socket(InetAddress.getByName(hostname), port);
 pfd = ParcelFileDescriptor.fromSocket(socket);
 
} catch (UnknownHostException e1) {
 // TODO Auto-generated catch block
 e1.printStackTrace();
} catch (IOException e1) {
 // TODO Auto-generated catch block
 e1.printStackTrace();
}

I try to set ParcelFileDescriptor to MediaRecorder.

_mediarecorder = new MediaRecorder();
_mediarecorder.setOutputFile(pfd.getFileDescriptor());

Android source code is here.
Next Server side program. this program do in my pc(192.168.1.2).
and this is java language.
I create server socket. port number need to be same between client and server.

ServerSocket svsock = new ServerSocket(5000);

I prepare file.

outFile = new FileWriter("xyz" + i + ".mp4");

I wait client(Android) connecting by acccept.

Socket sock = svsock.accept();

If client(Android) connected, I use accept socket sock.

sock.getInputStream()

I prepare BufferedReader and BufferedWriter, and I write received data to the file.

BufferedReader in = new BufferedReader(new InputStreamReader(sock.getInputStream()));
BufferedWriter wt = new BufferedWriter(outFile);
while(sock.isConnected()) {
 int line = in.read();
 if (line == -1) {
  break;
 }
 wt.write(line);
}

If client(Android) connecting finished, I close.

outFile.close();
sock.close();

server sid source code is here.
IMPORTANT, First server side do, Next Client(Android) do.

server side recive file analysis.
