How does WebRTC use libjingle?

Question

I download WebRTC's source code, but I can't find any libjingle's code at the WebRTC, and can't find how WebRTC use libjingle (can't find such as XmppTask Class in WebRTC's code)

Can anyone give me a guide?

Answer 1

Libjingle is now part of the WebRTC project and code base. WebRTC is a set of API's that make video, audio, and data interaction simple through a peer-to-peer connection. Where as Libjingle is used as a part of the WebRTC implementation to handle NAT traversal and stream handling.

Libjingle was initially used solely through XMPP to create a point-to-point connection between two chat clients. The technologies used are ICE, STUN, and TURN.

WebRTC has a large focus on Javascript mainly because its core usefulness is using the functionality through a browser. However, WebRTC (with Libjingle), can be built for many platforms and has a number of different APIs in various languages.

Libjingle is written in C++, so can be used by itself without WebRTC. However, I recommend using Libjingle's functionality through the way of the WebRTC APIs.

Yes, libjingle folder in webrtc has been removed in the lastest version. You can ignore it.

What does this mean? What replaces libjingle? – Struthious

Answer 3

These are two separate packages.

WebRTC is the multimedia part only - nothing to do with signaling (which is what XMPP and Jingle are).

libjingle is used to build an application that runs on a device or a PC while WebRTC is designed and targeted at being integrated into HTML pages using a web browser.

The two aren't mutually exclusive, as I have answered below. There are non-javascript APIs for WebRTC. – Eardrum

Answer 4

WebRTC - audio/video/data transfer p2p. Signalling - establishes connection between 2 WebRTC based apps. Take a look over this android webrtc videocall app and this nodejs signalling relay. You send a 'message' (check in file sockets.js in relay project at the following line

`client.on('message', function (details) {`

to see what's happening with it) of type 'init' from device A to device B, then device B creates an offer to device A. After that A answers to B, exchanging Ice Candidates then video connection is ready. (I'm sorry if i wasn't very explicit).
