Build Status

WebRTC for Golang.

Current Status:

As of October 2019, this repository is not actively maintained. The project for which it was developed is now using pion/webrtc instead.

Usage

To immediately see some action, try the chat demo from two machines (or one...)

  • git clone https://github.com/keroserene/go-webrtc
  • cd go-webrtc
  • go run demo/chat/chat.go

Type "start" in one of the Peers, and copy the session descriptions. (This is the "copy-paste" signalling channel). If ICE negotiation succeeds, a really janky chat session should begin.

To write Go code which requires WebRTC functionality:

import "github.com/keroserene/go-webrtc/"
And then you can do things like
webrtc.NewPeerConnection(...)
.

If you've never used WebRTC before, there is already plenty of information online along with javascript examples, but for the Go code here, take a look within

demo/*
for real usage examples which show how to prepare a PeerConnection and set up the necessary callbacks and signaling.

Also, here are the GoDocs.

Dependencies:

  • GCC 5+
  • TODO:

Package naming

The package name is

webrtc
, even though the repo name is
go-webrtc
. (This may be slightly contrary to Go convention, unless we consider the suffix to really begin at the last dash. Reasons: - Dashes aren't allowed in package names - Including the word "go" in a Go package name seems redundant - Just calling this repo
webrtc
wouldn't make sense either. - Also you can rename imported packages to whatever you like.

(e.g.

import "foo" "github.com/keroserene/go-webrtc"
)

Building

Latest tested native webrtc archive:

88f5d9180eae78a6162cccd78850ff416eb82483

There are currently two ways to build gowebrtc: the easy way, and the hard way.

The hard way is to build from scratch, which involves Google's depot_tools and chromium stuff, gclient syncing, which takes a couple hours, and possibly many more if you run into problems... along with writing a custom ninja file and concatenating archives correctly and such.

See webrtc.org native-code dev.

The easy way is to use the pre-built archive I've provided in

lib/
.

Once the archive is ready, cgo takes care of everything, and building is as easy as

go build
or
go install
.

TODO(keroserene): More information / provide a real build script to automate the hard way so it becomes the easy way. (See Issue #23)
