Stops sending media from sender. The RTCRtpSender will still appear

in getSenders. Doing so will cause future calls to createOffer to
|
||||
mark the media description for the corresponding transceiver as
|
||||
recvonly or inactive, as defined in [JSEP] (section 5.2.2.).
|

|

When the other peer stops sending a track in this manner, an ended
|
||||
event is fired at the MediaStreamTrack object.

6. If sender is not in senders (which indicates that it was removed
|

due to setting an RTCSessionDescription of type "rollback"),

then abort these steps.

12. Update the negotiation-needed flag for connection.
