Streaming video and audio over a network?

Question

C++ / C#

There was a need to write, do not laugh, an analogue of Skype. Those. add to an existing project (secure chat written in c++) the ability to communicate in video mode. Tell me where and what to read about the transmission of video and audio information over the network. Maybe there are sources somewhere? I will be glad for any information. Thank you.

Answer 1

I recommend a bunch of Xmpp + SIP.
From what to read:
xmpp.org/extensions/xep-0166.html
xmpp.org/extensions/xep-0167.html
xmpp.org/extensions/xep-0176.html
xmpp.org/extensions/xep-0177.html
Chapter 9 of XMPP: The Definitive Guide.
As well as books:
Internet Multimedia Communications Using SIP: A Modern Approach Including Java Practice.
SIP: Understanding the Session Initiation Protocol, Second Edition.
Smack library for working with XMPP in Java.
www.igniterealtime.org/projects/smack/
It implements the necessary functionality for working with audio. I don't know about video.
