Cross-platform Webrtc support for Unity apps βπ²
We needed a cross-platform webrtc solution for Unity, based on webrtc's unityplugin example that supports win32
, and winuwp
(theoretically linux and mac are supported as well, but untested). The β¨ magic β¨ of this repository is threefold:
- We support a winuwp (hololens compatible) binary
- We include a sample signalling implementation
- We provide a working end-to-end example
Officially supports Unity 2017.4.x (LTS) and Unity 2018.3.x
- Import the latest release package
- Take a look at the
UnityWebrtc\Examples
directory - Run an example to ensure your a/v hardware is working
- A detailed walkthrough describing the managed components is coming soon
The basic signal example (WebrtcBasicSignalExample.unity
) is designed to quickly demonstrate what managed code we'd need to write to configure a peer instance using a service to exchange sdp information (handshake) and ice candidates (NAT traversal).
To use it, one needs to set up a few dependencies:
- Clone, setup, and run an instance of node-dss (instructions at link).
- Modify the
WebrtcSignalControls
script via the inspector, on theWebrtcSignalControls
object to point at yournode-dss
server url.
Once the server is running and Unity is configured, both clients should be able to exchange information by device id. The device id is displayed across the top left of the screen, and should be typed into the remote peers input field.
For instance, to connect Peer A (device id: 1) with Peer B (device id: 2) the targetId
input field for Peer A should have the value 2
. For Peer B, it should have the value 1
. A connection can not succeed unless both peers have the input field populated.
Once the targetId
field is filled on both peers, either peer can begin the connection by clicking the offerButton
.
At this point, sdp messages (handshake data) and ice candidates (NAT traversal data) should be sent via the server, and the clients should be able to connect successfully.
To better understand the API space of this solution, take a look at the hosted API docs.

In editor, Win32
is supported - this means if you're on Windows and you hit "Play" in the Unity Editor, your application should just work. For other platforms, one must produce a Unity Player build in order to fully test.
No contributing guidelines at this time. However, to produce a new unitypackage
when a new Release is needed, one must use Unity and select these fields:
