Question

I am developing an Android app that should be capable of streaming video to a local server on my network without storing it on SD card.

For this I have made simple socket application in C# that listens to the specific IP:PORT

On Android part, I had set the setOutputFile() to this IP:PORT using socket.

This application starts perfectly on Android phone but it does not display preview and when I start recording it exits without any exception. It also do not send any data stream to the network.

When I set the setOutPutFile() to SD card, it works perfectly and records video also.

For the server part, when I send the data from any other app (from PC) to the same IP:PORT, it receives the data.

In short, I want to establish the communication channel between PC and Android using socket for streaming.

Here is my Android code:

 Socket soc=new Socket("192.168.1.3",8210);
 ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(soc);
 ...
 ...
 // other Recorder setup steps
 ...
 ...
 Recorder.setOutputFile(pfd.getFileDescriptor()); // working fine for sdcard
 Recorder.setPreviewDisplay(holder.getSurface());
 Recorder.prepare();

Here is my server app that is in C# and runs on PC:

 socketForServer = new TcpClient("192.168.1.3", 8210);
 NetworkStream networkStream = socketForServer.GetStream();
 byte[] rData = new byte[1024];
 networkStream.Read(rData, 0, 1024);
 ...
 ...
 // process rData
 ...
 ...

I am not able to understand the problem that is occurring here. Am I going in right direction?

Answer 1

There was problem in my server code.

I had to use TcpListener in place of TcpClient.

Following is the correct code:

TcpListener listener = new TcpListener(ipAddress, 8210);
Socket s = listener.AcceptSocket();
NetworkStream ns = new NetworkStream(s);
.

.
//reading the data from stream
