The read-only property RTCPeerConnection.currentRemoteDescription
returns an RTCSessionDescription
object describing the remote end of the connection as it was most recently successfully negotiated since the last time the RTCPeerConnection
finished negotiating and connecting to a remote peer. Also included is a list of any ICE candidates that may already have been generated by the ICE agent since the offer or answer represented by the description was first instantiated.
To change the currentRemoteDescription
, call RTCPeerConnection.setRemoteDescription()
, which triggers a series of events which leads to this value being set. For details on what exactly happens and why the change isn't necessarily instantaneous, see Pending and current descriptions in WebRTC connectivity.
Unlike RTCPeerConnection.remoteDescription
, this value represents the actual current state of the local end of the connection; remoteDescription
may specify a description which the connection is currently in the process of switching over to.
Syntax
sessionDescription = RTCPeerConnection.currentRemoteDescription;
Return value
The current description of the remote end of the connection, if one has been set. If none has been successfully set, this value is null
.
Example
This example looks at the currentRemoteDescription
and displays an alert containing the RTCSessionDescription
object's type
and sdp
fields.
var pc = new RTCPeerConnection(); … var sd = pc.currentRemoteDescription; if (sd) { alert("Local session: type='" + sd.type + "'; sdp description='" + sd.sdp + "'"); } else { alert("No local session yet."); }
