[[ixnx:wrtc:js:api:wrtc:get|wrtc.get("videoSources")]], [[ixnx:wrtc:js:api:wrtc:get|wrtc.get("audioSources")]] and [[ixnx:wrtc:js:api:wrtc:get|wrtc.get("audioDestinations")]] return a list of video sources (cams), local audio sources (mics) and local audio destinations (speakers) available.

Property //label// of each object contains a descriptive name of the media device, eg "External USB Webcam"

Property //deviceId// of each object contains the unique ID for that media device that you need to set [[ixnx:wrtc:js:api:wrtc:audiosource|wrtc.audioSource]], [[ixnx:wrtc:js:api:wrtc:audiodestination|wrtc.audioDestination]]  or [[ixnx:wrtc:js:api:wrtc:videosource|wrtc.videoSource]] to to select that audio or video device.
