RTCIceCandidateInit

WebRTC API's RTCIceCandidateInit dictionary, which contains the information needed to fundamentally describe an RTCIceCandidate . RTCIceCandidateInit is used when using new RTCIceCandidate() to create a new ICE candidate object. It's also used as the return value from the RTCIceCandidate.toJSON() method, and can be passed directly into RTCPeerConnection.addIceCandidate() to add a candidate to the peer connection.

特性

candidate 可选
The ICE candidate-attribute . If the candidate is an indicator that there are no further candidates (rather than representing a new candidate), this is the empty string ( "" ). The default is the empty string.
sdpMid 可选
The identification tag of the media stream with which the candidate is associated, or null if there is no associated media stream. The default is null .
sdpMLineIndex 可选
The zero-based index of the m-line within the SDP of the media description with which the candidate is associated, or null if no such associated exists. The default is null .
usernameFragment 可选
A DOMString containing a string which uniquely identifies the remote peer. This string is generated by WebRTC at the beginning of the session, and at least 24 bits worth of the string contain random data. The string may be up to 256 characters long. This property has no default value and is not present unless set explicitly.
