Allows MediaStream to switch tracks without setting srcObject this allows MediaRecording to continue recording.
The MediaRecorder is designed to stop recording when you switch streams during recording.
Use RTCPSender to switch stream without MediaRecorder to stop recording. Another solution would be using MediaSourceBuffers but that is way more error sensitive in case of different codes etc..
A stream where you switch for instance camera with screenshare and back without need to stop and start the MediaRecorder
