Now i know what is UDP. And i found one more thing useful.
enet purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol). The primary feature it provides is optional reliable, in-order delivery of packets.

ENet is NOT intended to be a general purpose high level networking library that handles authentication, lobbying, server discovery, compression, encryption and other high level, often application level or dependent tasks.

First i will create a window and message loop using GTKMM, after that i will check that the camera is attached with PC or not using OpenCV. Then i will establish a network connection (UDP Protocol? Socket? i dont know what are these, but i am reading about this from wikipedia). Then i will find all IP addresses that are currently active, okay.
After that a window will appear having the list all active IP address with their HostName, user will select any host with witch he want to chat, and send request to that particular host, if request accepted then a window will appear having a video frame on it...

Am i right??
Correct me if i am wrong some where..

Thanks

Thanks programmersbook
What i have understand yet.

1. (wxWidgets/QT) in my case GTKMM because i have used already.

2. ffmpeg. for video encoding and decoding

boots libs for what purpose??
And how to get data from LAN??
How to get from video camera attached to PC??

What will be the Data flow diagram??

Is there any other alternative of "ffmpeg" that can be used with C++???

This must be a frequently asked question, but I can't find the answer in the FAQ, or in the recent archive of this list, or by using
google with the keywords I thought of.

I would like to use libavcodec.dll and libavformat.dll in my Windows
XP Visual C++ 2008 project. However, I would prefer not to download a whole new compiler environment and compile ffmpeg from sources, just to get the dlls.

Is there anyplace I can find relatively recent precompiled dll's
and a matching header file?

Description
I want to have a video conference system.

1. That is the client-server model.
2. The client can send audio/video/document(like ppt.doc.xls..)/application sharing/chat functions.
3. The client's window can receive 16 videos(from other clients).
4. The client can work on windows platform.
5. The server can work on windows or linux(it's better).
6. The video can support 160*120/320*240/640*480...

I copied this description from Here
The problem is, when i read such a description i completely get confused that how and where to start.
Suppose this task is assigned me to complete, so please provide me the guide lines where to start.

I know windows API little bit and made small projects during study session, but i don't know how to render video on the Window.

Question is: What i need to know to complete this project??

Thanks..

Can we catch event from Flash to C++,

For example if a user press a button in Flash, we want to activate a method in our C class,
I search on google but i did to get any thing satisfactory.
They only show how to play a Flash movie in MFC dialog using ShockWave ActiveX Control.

What i want now, if i press a button in Flash then there must be method in c that must be execute.

Hope u understand what i am asking for.

{
	form f = new FacForm();

Suppose i have a class called Vector3

methods and attributes are defined in Vce.h file,
methods of this class are implemeted in Vec.cpp file,

now i want to distribute this class to my other xxx(what so ever),

What i want:
1.Allow them to see what methods and attributes are available in this class.
2. Allow them to use methods of these class into their code

What i don't want:
1. I don't want to allow them to see how methods are implemeted.
2. Dont want to allow them to edit this class, but they can enhance the class compability by making their own derived classes using this class as a base.

How to achive this??

Any tutorial, or article related this plz put the link here.

Thanks.
