The read-only property sdpMid
on the RTCIceCandidate
interface returns a DOMString
specifying the media stream identification tag of the media component with which the candidate is associated. This ID uniquely identifies a given stream for the component with which the candidate is associated.
This property can be configured by specifying the value of the sdpMid
property when constructing the new candidate object using RTCIceCandidate()
. If you call the constructor with an m-line string instead of an RTCIceCandidateInit
object, the value of sdpMid
is extracted from the specified candidate m-line string.
Syntax
var sdpMid = RTCIceCandidate.sdpMid;
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.
