Video Conferencing Project in Java Source Code

My video conferencing project was completed as 300 project for 3rd year.It is not totally completed. There is some bug in here.To solve these bugs and to help other students this project is open.It is first try to make a project open source in this way so it can be modified.Any kind of question against this project will be answered. As this project was created in 3rd year 1st semester and now i nearly completed my BSc. so there will be little description about this.I will try to describe every class and function later when i get the chance.  



For more details and how to build and run go to this link  in github.com.

2. P2P Chat
3. P2P Audio Chat
4. P2P Video Chat
5. Completely Automated
6. H263 compression Video
7. raw audio

Descriptive feature:

i. Text chat, File transfer are done through server, where server is the middle-man or a relay. Meaning, all of the data are goes through the server. So if anyone has the server running on a public IP , then it can be use in any network. This feature is not true for Video chat.


PREREQUISITE:

1. JUST INSTALL jmf-2.1.1 e 32-bit.
2. Require Java SDK installed 32-bit.


Compatibility:

IDE:
1. Tested with JCreator Pro.
2. Tested with Eclipse.


COMPONENT:

1. A Relay Server.
2. A Client.


1. Relay Server:
----------------
```
i.   ClientListener.java
ii.  ClientMap.java
iii. Clients.java
iv.  Main.java
v.   MessageListener.java
vi.  ServerConstant.java
vii. ServerMonitor.java
viii.ServerStatusListener.java
```

2. Client:
----------
```
i.   AVReceive2.java
ii.  AVTransmit2.java
iii. ClientConstant.java
iv.  ClientListListener.java
v.   ClientListPanel.java
vi.  ClientManager.java
vii. ClientStatusListener.java
viii.ClientWindowListener.java
ix.  FileReceiver.java
x.   FileSender.java
xi.  LoginFrame.java
xii. LogInPanel.java
xiii.Main.java
xiv. MessageRecever.java
xv.  MessagingFrame.java
xvi. VideoTransmit.java
```

Configure:
----------

To run this project you must have 3 different PC.
ex:
1. Server PC
2. Client 1 PC
3. Client 2 PC

You also need to install jmf-2.1.1 e in every PC. After that installation you must check your webcam with JMF application available on your PC. If the webcam is accessible through your JMF app then this project will certainly work.

After that you need to build the Server and Client code with the correct IP and Port in file ServerConstant.java and ClientConstant.java. You can build this project with any JAVA IDE. But I have encouraged to use JCreator Pro.

For Server settings in file ServerConstant.java -

```
public interface ServerConstant
{
    public static final int SERVER_PORT=12345;
    public static final int BACKLOG=100;
    public static final int CLIENT_NUMBER=100;
    public static final int MULTICAST_SENDING_PORT=5555;
    public static final int MULTICAST_LISTENING_PORT=5554;
    public static final String MULTICAST_ADDRESS="239.0.0.1";
    public static final String DISCONNECT_STRING="DISCONNECT";
    public static final String MESSAGE_SEPARATOR=" >> ";
   
}
```

SERVER_PORT=12345 is the port in which server is listening/waitting for client.


For Server settings in file ClientConstant.java -
```
public interface ClientConstant
{
    public static final String SERVER_ADDRESS="172.17.0.32";
    public static final int SERVER_PORT=12345;
    public static final int CLIENT_NUMBER=100;
    public static final String DISCONNECT_STRING="DISCONNECT";
    public static final String MESSAGE_SEPARATOR=" >> ";
}
```

SERVER_ADDRESS="172.17.0.32" is the address of the server PC and SERVER_PORT=12345 is the server listening port.

Try Out:
--------

After all of the installation, settings and build just RUN the server on a PC by server Jar or from your IDE run. Then from Server GUI just click on *Start* button.

Now from another 2 PC use the client jar or run from IDE and provide Username on the User window and click *Signin*.
Now you are done. Now any user login in your server can see the other user who are logged in to your server.

Then from friendlist click on the friend and a new window will arise for chat. On that window there will be a video chat start button and a text chat send button. You can use any one for you specific cause.

Troubleshooting:
----------------

If you don't see the video starting please change the value of your webcam's descriptor("vfw://0") on class *MessageRecever.java*

```
AVTransmit2 vt = new AVTransmit2(new MediaLocator("vfw://0"),pt,"20006",null);
AVTransmit2 at = new AVTransmit2(new MediaLocator("javasound://8000"),pt,"20008",null);
```
It may be --

1. vfw://0
2. vfw://1
3. vfw://2 , etc.

JCreator Pro build issue:

If you are using Jcreator you must have to add JMF library path in project properties. It can be done by

*Project->Project Settings->Required Libraries* and add JMF folders library name with location as archive.

Known Issue:

1. We don't have SIP.
2. We don't have STUN, TURN.
3. When in a video call you can't have a text chat session.
4. We don't have any authentication mechanism for user sign in.
5. File transfer is disabled.

i ran the server and i ran the client, but after signing with the client it doesn´t show anything but the message you´re connected: 127.0.0.1 (i change the ip in the client constants to my localhost)
is it supposed to show something else in the client besides signing in??

Reply

@Raúl Garcia : Are you using 1 PC for both server and Client?
If so did you set the server end server constant IP/PORT and client end server constant IP/PORT same?

If you are using one pc I think output is right. Use another instance of client in same pc and see does 2 client exchange there presence or not?

I ran the server side code on a different laptop and client side code on a different laptop, but even after successful compilation and running of the code, I am not able to do a video or text chat. After signing in from the client side it simply says, "you are connected to 172.17.0.32" Is it supposed to show anything else?

Reply

It's ok. Now you need to login in server with another client. Then you can see one another from both client and can make call by clicking on the call/video button.

Thanks a lot for your reply. I did as you said and now I can see buddy list and option to video call and chat. But we are facing another problem, messages from one client are not reaching another client. Like when one client types "hi", it goes to the server, it is seen there but it doesn't reaches the other client. Further, one one client and server we are not able to run jmf as it has compatibility issues with 64 bit os. So is my problem arising due to compatibility issues of jmf or we nee to do something more?

If it may help, see you need to get a hub or switch before you can perform this project. You have to run only server side code on one laptop, run only client side code on another laptop and then run client side code on another laptop. Connect all these three laptops by a hub or a switch. Give them manual ip. The ip of server is defined to be 172.17.0.32 with default sub-net mask 255.255.0.0 and don't give any dns server or default gateway. The ip's of other two client should be in the same subnet, so that they can communicate with each other, I gave the ip's as 172.17.0.35 and 172.17.0.37. After you have done so, you can run the codes on the respective pc's and voila! you will see the log in page and after the two clients log in they can chat with each other.

Configure your IP settings correctly and use the latest code. Follow me on github.com https://github.com/robelsharma. I have committed a latest fix for a previous issue. *127.0.0.1* is localhost not a valid IP. Again you can test 2 client in one machine.

Sir I have one problem . I couldn't see the video. Actually do I need to run the clients in different PC's to see the video or running the different clients in the same PC, will it do?
Please help me with it.

Reply

You have to use 2 different PC for client. The both clients' IP must be reachable from one another. (Just Ping your one client IP from another client.)

I try to run this code.but I cannot import the messangerclient package in the client side code.so can you help me wit this?

Reply

I have tested it with both Jcreator Pro and eclipse and it seems working. If you have Jcreator pro the available source code has the project file named Video Conferencing2.jcw . You just need to click it!!

Reply

Can you please explain the role of server in this code.

Reply

Server is used for presence, text chat and for client IP exchange.

Set the IP address of your PC on server constant class. Then build and Run and Start server.
Now from client GUI just give the server IP and connect to it.

On the description I have pointed out that you have to install jmf and on jmf manager application you have to set and get the webcam. I am quoting my point bellow --
"You also need to install jmf-2.1.1 e in every PC. After that installation you must check your webcam with JMF application available on your PC. If the webcam is accessible through your JMF app then this project will certainly work."

Can you help me or give me any tips how to make multiple users chatting and video?!

Reply

Sorry Taulant. This project says video conferencing but only p2p one is complete. But multiple user chat is ok.

I have an error when im trying to open video with jmf.When i run at my laptop it shows this error "Exception in thread "VFW Request Thread"" but not in my pc.Is it problem with jmf with 64 bit?! And how to modify for multiple user for chat?

Reply

For multiuser chat I guess you have to do some change on code, because on GUI it is not enabled.
