Google Goggles和Layar使用哪种应用层协议？

Question

These applications stream video from client app to their own server. I am interested in knowing what type of protocol they use? I am planning on building a similar application but I dont know how to go about the video streaming. Once I get the stream to my server I will use OpenCV to do some processing and return the result to the client.

Answer 1

I recommend you to send only a minimum of data and do the processing as much as possible on the client. Since sending the whole video stream is a huge waste of traffic (and can not be done in realtime I think)

I would use a TCP connection to send an intermediate result to the server, that the server can process further. The desing of that communication depends on what you are sending and what you want to do with it.

You can wrap it in xml for instance, or serialize an object and so on.
