Web/API/RTCIceCandidateInit/sdpMid

The optional property sdpMid in the RTCIceCandidateInit dictionary specifies the value of the RTCIceCandidate object's sdpMid property.

Value

A DOMString which uniquely identifies the source media component from which the candidate draws data, or null if no such association exists for the candidate.

Note: Attempting to add a candidate (using addIceCandidate()) that has a value of null for either sdpMid or sdpMLineIndex will throw a TypeError exception.
