I need to implement a screen sharing application using BFCP but not able to find much, can some one please describe or explain in brief how this can be achieved. There is very little information about this on the internet now sure why. SO doesnot even have a tag for BFCP
I have gone through the following links from cisco and also found an outdated library for implementing it. Any help is greatly appreciated.
Is there any other way for sharing screen in a video SIP call?
Sip support multiple streams. Number of SDP streams is unlimited, both end should support new one.
Fore sure no problem send screen sharing info as video stream and send any special info related(like mouse move etc) by SIPMESSAGE. However such setup will require SIP expert in team.

Basicly, I'm trying to read a game's chat and catch actions from the user.
Here is the image which I will explain the situation with :
1: I took a message in the chat
2: I tryed to find it in the game's memory with Cheat-Engine
3: By examining every addresses where it was found, I ended up to this one, which contains the chat formated with what seems to be html..
That part is only the bottom part of the chat. (I see the rest of it if I scroll up)
So, I asked myself how could I read game variable to interact with the game.
Another thing I'm trying to achieve is to catch the user's actions so I can display some information in a winform.
I've just read about packet sniffing, it seems interesting for what I'm trying to do.
I tryed to read packets going in and out of this app with WireShark. Every action in game was sending a few packets, but I couldn't read them as they were just a bunch of weird characters. I tryed to decrypt them using a few methods I got on WireShark's forum without success. I was asking myself, even if I could see them in Wireshark, how am I gonna do that programmatically..
There is certainly a good way to do this, as we often see bots in this game.
Considering the number of bots playing "in team", I'm pretty sure they do not use clicks, but they run something in background that sends requests.
How do you make such a bot that fight, talk, interact with players automatically?
This game is Dofus, powered by Adobe Air.
I usually program with c++ and c#, but I was wondering what's the best way to do this.
I need a kick in the right direction!
Maybe trying a tcp/ip listner control (or use tcplistner class in c#) in your c# project with the appropriate port to catch requests (& responses). Information sended could be compressed so you may want to try some standard algo.
Did you try reverse engineer the AIR app ?
Monitoring your network while watching a Youtube live streaming (http://youtube.com/live/), you can see that they are downloading a file to your cache, and this file is actually the live stream.
Bitgravity use the same way to deliver their live stream since years (Check Twit.tv for example).
Does anyone know what is the server side used for this ? and how can someone achieve this instead of using Adobe FMS, Wowza or Red5 ?
These guys have put together an open source video streaming server, so you can look at the source code and see how they did it.
They wrote it in Java.
The current version is a working prototype, which showcases the main ideas. The main design goal is low resource usage.
there can be many ways to implement streaming, i dont think google will let you know how they do that, but it can be done even by simple http, just a simple stream that sends the video data without the "range" header so its just go on and on
I have a flash based game that has a high score system implemented with a SOAP service. There are prizes involved and I want to prevent someone from using FireBug or similar to discover the webservice path and submit fake scores.
I considered using some kind of encryption on the data but am aware that someone could decompile the swf and work out how I did it.
I also considered using an IP whitelist but since the incoming data will come from the users IP and not the servers that won't work. (I'm sure I'm missing something obvious here...)
I know that there is a tried and tested solution for this, but I don't seem to be asking google the right questions to get to it.
Any help and suggestions will be appreciated, thank you
What you want to achieve is impossible. You can only make it harder for people to do. The best you can do is to use encryption and encrypt the SWF it self, which usually causes higher filesize and poorer performance.
The safest method is to evaluate or even run the whole game on the server. You can try to determine whether what the client sends you is possible at all. Rather than making sure people use your client, you're making sure people play the game according to your rules.

All security is based on making things hard. It never makes things impossible. How about having your game register with a separate service when it starts up. It could use client information to build some kind of special code that would be unique for each iteration of the game. The game could morph the code in a way that would be hard to emulate. Then when the game is over the score gets submitted with the morphed code and validated on the server side.
I want to record voice online and I guess I need to use FMS or Red5 and I don't know how to use Red5 with Asp.net, actually this is my first attempt to handle such a thing and currently I am a .net developer.
So someone please show me a way to handle it and show me how to use Red5 with Asp.net.
Thanks in advance.
This is the nice page which has very good infromation abou red ands ASP http://www.aspnetajaxchat.com/Deployment_Guide.pdf

Some more information avilable in are there any ASP.NET with Voice Recording sample codes?
I have successfully written an asp.net application to stream multiple users P2P video using Red5.
Integration of red5 is actually simple. Once you've got it working on your Server/VM all you have to do is install the olfa Demo and you can write a player/streamer in flash. You just have to set the netconnections. One for the incoming stream and another for the outgoing stream. Then you'd have to add a mic & camera capture to attach them to the outgoing stream. If you want to make your player/Streamer more robust you can use a combination of Javascript and a webservice(AJAX) to control what streams to where.
You weren't very detailed on what you wanted to do otherwise I could have probably assisted you further.
For example code go to

In Blackberry application I want to check what type of network connection is being used on particular phone, whether it is BES/MDS,BIS-B or Direct Tcp.
Is there any way to find out this?
Many applications like Jive,Opera and many more are doing this kind of check.
Please help.
The question is quite logical and I do agree with Richard as well. Though a better answer lies in the fact that there can be a logic developed which would involve Service Book parsing and making use of system listeners to check the current coverage status.
I had attempted to make one such logic once in my project which worked for me. I had shared my findings and understanding about the concept in more detail at my blog post. May be you would like to check once.
You can find my blog post here.
Your question springs from an incorrect assumption. A Blackberry could be communicating over any or all of those channels simultaneously. In fact any application may as well. At any particular time you can determine if coverage is sufficient for one of those channels, or register a listener for notification of changing status using net.rim.device.api.system.CoverageInfo.
