Need help in video calling app for iOS

Question

I am creating a simple video calling app where audio/video will stream from one device to other but problem is I don't know how video calling works especially how to get going with it in iOS . Until now I have captured video by using AVCaptureSession and used buffers from this delegate method

 - (void)captureOutput:(AVCaptureOutput *)captureOutput
didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer
       fromConnection:(AVCaptureConnection *)connection
{}

For testing I have written the audio and video buffers to documents directory by using AVAssetWriter. After that I easily stored the video to iPhone gallery or played it with MPMoviecontroller player .

Now , I have following problems

I do not know how to send these buffers to server continuously and then server to other device.
If I got successful in sending data to other device then how will I decode it to show video on other device .

I have searched about it . like sending data through udp packets but I also do not know anything about it .

If I get proper knowledge what to do then I am sure I will be able to do it . Please provide me your views that what should i do to achieve this . I will be thankful to you for your help

Please also tell me if i am on right track by capturing buffers . — sajwan, Jan 07 '13 at 11:41
