View Replies View RelatedEncrypted Video Chat Program Using JMF
Oct 23, 2014I am trying to make an encrypted video chat program using JMF. I have successfully written the "video chat" part - which includes getting data from webcam and transmitting it using RTP, but how to get raw data video to encrypt it before it stream between the webcam and the network.
For RTP I am using RTPManager, and for reading from the webcam I am using this code:
DataSource ds;
CaptureDeviceInfo di = null;
StateHelper sh = null;System.out.println("Started Video");
String str1 = "vfw:Logitech USB Video Camera:0";
String str2 = "vfw:Microsoft WDM Image Capture (Win32):0";
String str3 = "vfw:Microsoft WDM Image Capture (Win32):0 : vfw://0";
[Code] .....
I plan on using a stream cipher for encryption, maybe RC4.

Inserting Video Into Graphics?
Feb 12, 2014So I'm doing a project for my CS class where we have to create a snowman doing something. My picture is of Vince Young in the 2005 Rose Bowl. I'm trying to make the actual video clip from Youtube (do I need to download it? If so I can do that) appear on the scoreboard, but how.

There are 3 other files that make the actual Snowmen.Also, would I need to download the mp3 sound file seperately and play that, or will inserting the video do both?
Small Chat Lobby
Feb 4, 2014Me and my brother are working on a small java project to learn network programming and get some experience working with networking code. We decided to make a relatively simple client/server program where clients get into a simple chat lobby and can invite others to play small games(like pong). The basic server code has been written, and we have made a special client that is used for debugging.
We use a self-defined protocol of Strings where a message looks like "4-|user,pass". The number before the delimiter "-|" is the operation code, that tells the server what kind of message this client sends. Based on that number, the server dispatches the message to the appropriate handler method. 4 is authentication for example, and the handler looks the user and pass up in a file and if found, returns true, otherwise, false. Then the server responds to the clinet with 2-|"any message" where the client will recognize opcode 2 as a "authentication accepted" and proceed with the next part of client code. In a similar way, we plan to write all message types(both in the game, in the lobby and in a game setup room).
While testing we ran into a problem where the BufferedReader .readLine() does not seem to be a blocking call like it should be, so the client keeps spamming 'null' in the output field that we made to see the server response to the message we send. When we try to debug the server code and set breakpoints at the suspicious locations, it strangely skips both while(true) loops without activating either breakpoint and executes the finally{} code, even though the client did not close the connection and the second while loop was never entered. The first while loop IS entered though, because the test client gets a "0" on its output, which is the server message indicating "please authenticate yourself".
Also, if we approach things in a dumb way that can be done way more efficiently or easier to read/manage, please do tell. Keep in mind we are beginners though! We decided to use messages in a string format and decode it at both sides as it seemed easier than transmitting java objects and making sure they are of the same type, also for reducing overhead as much of possible. URL....
The server code:
package Chatroom;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.HashSet;
/**
* This is the main server class. It is the core of the server functionality, and the listener for incoming clients that will spawn threads to deal with clients, track their information, change their states and ultimately, clean up after all clients by keeping the data structures up to date.
