But I will need to change it to record to buffer. It will be a service run in background. And I may have some others application (on the same device) that need to access to this buffer and display the video in real time. I'm thinking about a RTSP server on mobile, but it will be very complex. So I just need a solution to transfer a video buffer between applications on the same device. Can you give me any idea?

I just need something simple Re: Communication between applications: a camera service Code-o-mat22-Jun-10 9:05 Code-o-mat 22-Jun-10 9:05  The other application(s) that would connect to your app, are those also written by you (so you can make up any way to connect you wish) or you want to do some generic, standardized way? > The problem with computers is that they do what you tell them to do and not what you want them to do. < > "It doesn't work, fix it" does not qualify as a bug report. < > Amazing what new features none of the programmers working on the project ever heard of you can learn about when reading what the marketing guys wrote about it. < Re: Communication between applications: a camera service igala.net22-Jun-10 9:39 igala.net 22-Jun-10 9:39  The other applications/clients could be written by me and could be write be someone else, we have some clients that will use this service. I prefer a standard way, but the speed is in priority (because these applications are for mobile phone). So I'm interested in a specific solution too. Re: Communication between applications: a camera service Code-o-mat22-Jun-10 9:47 Code-o-mat 22-Jun-10 9:47  Well, if you are allowed to come up with the protocol yourself then what's wrong with communicating through a socket? It shouldn't be that hard to come up with a simple, easty to implement way to connect and transfer data, of course i have no real overview of your project so i can't know. Other methods that come to my mind are named pipes or shared memory, don't know if any of these is available on the mobile platform or not. > The problem with computers is that they do what you tell them to do and not what you want them to do. < > "It doesn't work, fix it" does not qualify as a bug report. < > Amazing what new features none of the programmers working on the project ever heard of you can learn about when reading what the marketing guys wrote about it. < Re: Communication between applications: a camera service igala.net22-Jun-10 10:02 igala.net 22-Jun-10 10:02  I'm wondering about the speed, I need that should be in real time, like when you see the mobile phone camera. I don't know if I have to compress video before send it to socket. If I have to, so I need to compress and decompress video, the speed will be slow, I think. If I don't compress them, so the data packet should be very big, I don't know if I can make a stream. I see that youtube, dailymotion ... doing a stream. So I think the 2nd solution should be ok. That why in the first post I talk about a simple RTSP server. I prefer a common buffer/shared memory like when you make a communication between threads in one application, this solution is more efficient and simple. But I don't know if we can do the same way with some independent applications. Re: Communication between applications: a camera service Code-o-mat22-Jun-10 10:23 Code-o-mat 22-Jun-10 10:23  Hmm, i just checked the GlobalAlloc method and found out that GMEM_SHARE is obsolete and ignored by the method (and is provided for backwards compatibility with 16 bit windows), i guess i was living in the past, as i could have sworn this would still work. Anyways, here's[^] a list of (some) interprocess communication methods, maybe one of these could be used on a mobile device too. > The problem with computers is that they do what you tell them to do and not what you want them to do. < > "It doesn't work, fix it" does not qualify as a bug report. < > Amazing what new features none of the programmers working on the project ever heard of you can learn about when reading what the marketing guys wrote about it. < Re: Communication between applications: a camera service igala.net22-Jun-10 22:19 igala.net 22-Jun-10 22:19  thanks your helpful reply Re: Communication between applications: a camera service Code-o-mat23-Jun-10 0:21 Code-o-mat 23-Jun-10 0:21  Yourwelcome, i hope it did help. Could you tell me (and others who are reading this conversation maybe) which method you decided to use? Just curious... > The problem with computers is that they do what you tell them to do and not what you want them to do. < > "It doesn't work, fix it" does not qualify as a bug report. < > Amazing what new features none of the programmers working on the project ever heard of you can learn about when reading what the marketing guys wrote about it. < Re: Communication between applications: a camera service igala.net23-Jun-10 1:51 igala.net 23-Jun-10 1:51  I'm thinking about Pipes, File Mapping and a simple rtsp server (it means that TCP/UDP). I will do a/some test and tell you (not now, but when I done the test) which one I will use. If RTSP is "enough" simple, I prefer it, because it's a standard, so I can reuse for my other projects. Re: Communication between applications: a camera service Code-o-mat22-Jun-10 10:30 Code-o-mat 22-Jun-10 10:30  The "Using a File Mapping for IPC" part seems to be promising.

How to emulate virus alto21-Jun-10 22:38 alto 21-Jun-10 22:38  Strange problem: in order to check some securities issues in the organization I need to deploy a sample program that need to be recognized as a known virus or Trojan. The idea is to deploy simple program to all user's machines and check who will recognized it as virus and to log what was done by the user after it. Its must be recognized as a well known virus so the standard anti virus applications we have will catch it, but of course wont make any damage to the host machine. Any ideas?
