The read-only sdpMLineIndex
property on the RTCIceCandidate
interface is a zero-based index of the m-line describing the media associated with the candidate.
This value is specified when creating the RTCIceCandidate
by setting the corresponding sdpMLineIndex
value in the RTCIceCandidateInit
object when creating a new candidate with new RTCIceCandidate()
.
If you instead call RTCIceCandidate()
with a string parameter containing the candidate
m-line text, the value of sdpMLineIndex
is extracted from the m-line.
Syntax
var sdpMLineIndex = RTCIceCandidate.sdpMLineIndex;
Value
A number containing a 0-based index into the set of m-lines providing media descriptions, indicating which media source is associated with the candidate, or null
if no such association is available.
Note: Attempting to add a candidate (using addIceCandidate()
) that has a value of null
for either sdpMid
or sdpMLineIndex
will throw a TypeError
exception.
