@networked-aframe/naf-janus-adapter
Advanced tools
Network adapter for networked-aframe that uses the Janus WebRTC server as a backend.
naf-janus-adapter needs access to networked-aframe's NAF global variable. Include it after including networked-aframe but before the networked-scene is loaded.
naf-janus-adapter should support anything that supports recent WebRTC standards (right now, the RTPSender-based APIs for manipulating streams and tracks). At the time of this writing, that means that many browsers (e.g. Chrome) will require the use of the WebRTC adapter shim. If you're using NPM to build your A-Frame application, you should include webrtc-adapter as a dependency of your application; if you're using the browser distribution, you should include the WebRTC adapter prior to including naf-janus-adapter, as shown in the example code below.

Compared to other adapters like easyrtc, the janus adapter has a specific API,
you need to call NAF.connection.adapter.setClientId and
NAF.connection.adapter.setLocalMediaStream, see the Audio example
and the Audio with Camera example.
The audio:false on the networked-scene is not supported by this adapter.
If you want to mute the mic, you need to use
NAF.connection.adapter.enableMicrophone(false)
A specific behavior of the janus adapter is that connect() returns a
Promise (it's not the case with the easyrtc adapter).
The Promise returns when all peer connections to the participants are
established. So you can use this:
AFRAME.scenes[0].components["networked-scene"].connect().then(() => {
// do something
});
getMediaStream supports a second parameter to get the video stream instead of
the default "audio" stream. To get the video stream of a participant:
const stream = await NAF.connection.adapter.getMediaStream(clientId, "video")
4.0.0 allows the application to control when occupants are subscribed to. Occupants are no longer automatically subscribed to when they join. The application is now required to call syncOccupants and pass an array of occupantIds that it wants to subscribe to. This list should contain all occupantsIds that are currently desired to be subscribed to- including any that have already been subscribed to and want to continue to be so. Any occupants not on the list that are already subscribed to will be unsubscribed from.
NAF.connection.adapter.syncOccupants(arrayOfOccupantIds);
If you want to automatically subscribe to occupants on join, you may call syncOccupants with the availableOccupants array as the first argument once in the onConnect function.
NAF.connection.adapter.syncOccupants(NAF.connection.adapter.availableOccupants);
or set requestedOccupants to be the same array instance as availableOccupants in the adapter-ready event listener if this is more convenient for you:
scene.addEventListener('adapter-ready', ({ detail: adapter }) => {
// We don't use the syncOccupants API, set requestedOccupants to be the same array instance as availableOccupants
adapter.requestedOccupants = adapter.availableOccupants;
...
});
npm startnpm run buildnpm run releaseFor development on the same LAN with npm start and if you run the janus docker image locally, you can use the config
serverURL: wss://192.168.1.15:8080/janus; (change the ip by yours of course).
