@hthetiot my proposal for #533 is:

/** New track as been added. */
func peerConnection(_ peerConnection: RTCPeerConnection, didAdd rtpReceiver: RTCRtpReceiver, streams:[RTCMediaStream]) {

	NSLog("PluginRTCPeerConnection | onaddtrack")

	// TODO investigate why no stream sometimes and confirm still the case.
        let pluginMediaTrack = PluginMediaStreamTrack(rtcMediaStreamTrack: rtpReceiver.track!)

        if (streams.isEmpty) {
            self.eventListener([
                "type": "track",
                "track": pluginMediaTrack.getJSON(),
            ])
        } else {
            let pluginMediaStream = getPluginMediaStream(stream: streams[0]);

            self.eventListener([
                "type": "track",
                "track": pluginMediaTrack.getJSON(),
                "streamId": pluginMediaStream!.id,
                "stream": pluginMediaStream!.getJSON()
            ])
        }
}
