room.Connect(url, token)
then you disconnect from room
room.Disconect(true)

and so connect again in a different room with other token and roomName, the video track stack, and camera hardware never turn off.

publishing track {localTrack: LocalVideoTrack}
publishing track {localTrack: LocalVideoTrack}
publishing track {localTrack: LocalVideoTrack}
