构建与Android应用程序通信的C ++程序的最佳方法

Question

I'm working right now on a openCV project, that does some video processing.

I have a C++ program that runs on a PC, with some cameras connected, and it does the calculation and stuff and an Android app that controls the C++ program (something like aperture settings and starting some special calculations etc) and has a livestream of one camera.

The question is: How can these apps communicate. I thought about two TCP sockets.

• one for the LiveStream
• one for the control

What do you think? Will this work or is the a better way to implement this.

Thank you very much.

Answer 1

You've got a good guess. Sockets is a good solution for you.

But TCP socket for video stream is really bad practice. In case of minor network issues you'll get annoying hangs, etc.

Use UDP socket for LiveStream. Just be ready, that some of packets can be missed if WiFi signal is low or smth.
