方法

Also inherits methods from: EventTarget

addIceCandidate()

When a web site or app using RTCPeerConnection receives a new ICE candidate from the remote peer over its signaling channel, it delivers the newly-received candidate to the browser's ICE agent by calling RTCPeerConnection.addIceCandidate() .

addStream()

obsolete RTCPeerConnection 方法 addStream() adds a MediaStream as a local source of audio or video. Instead of using this obsolete method, you should instead use addTrack() once for each track you wish to send to the remote peer.

addTrack()

RTCPeerConnection 方法 addTrack() adds a new media track to the set of tracks which will be transmitted to the other peer.

close()

RTCPeerConnection.close() method closes the current peer connection.

createAnswer()

createAnswer() method on the RTCPeerConnection interface creates an SDP answer to an offer received from a remote peer during the offer/answer negotiation of a WebRTC connection. The answer contains information about any media already attached to the session, codecs and options supported by the browser, and any ICE candidates already gathered. The answer is delivered to the returned Promise , and should then be sent to the source of the offer to continue the negotiation process.

createDataChannel()

createDataChannel() method on the RTCPeerConnection interface creates a new channel linked with the remote peer, over which any kind of data may be transmitted.

createOffer()

createOffer() 方法在 RTCPeerConnection interface initiates the creation of an SDP offer for the purpose of starting a new WebRTC connection to a remote peer.

generateCertificate() static function

静态 RTCPeerConnection.generateCertificate() function creates an X.509 certificate and corresponding private key, returning a promise that resolves with the new RTCCertificate once it's generated.

getConfiguration()

RTCPeerConnection.getConfiguration() method returns an RTCConfiguration object which indicates the current configuration of the RTCPeerConnection on which the method is called.

getIdentityAssertion()

RTCPeerConnection.getIdentityAssertion() method initiates the gathering of an identity assertion. This has an effect only if the signalingState 不是 "closed" .

getReceivers()

RTCPeerConnection.getReceivers() method returns an array of RTCRtpReceiver objects, each of which represents one RTP receiver. Each RTP receiver manages the reception and decoding of data for a MediaStreamTrack 在 RTCPeerConnection

getSenders()

RTCPeerConnection 方法 getSenders() returns an array of RTCRtpSender objects, each of which represents the RTP sender responsible for transmitting one track's data.

getStats()

RTCPeerConnection 方法 getStats() returns a promise which resolves with data providing statistics about either the overall connection or about the specified MediaStreamTrack .

getStreamById()

RTCPeerConnection.getStreamById() 方法返回 MediaStream with the given id that is associated with local or remote end of the connection. If no stream matches, it returns null .

getTransceivers()

RTCPeerConnection 接口的 getTransceivers() method returns a list of the RTCRtpTransceiver objects being used to send and receive data on the connection.

removeStream()

RTCPeerConnection.removeStream() method removes a MediaStream as a local source of audio or video. If the negotiation already happened, a new one will be needed for the remote peer to be able to use it. Because this method has been deprecated, you should instead use removeTrack() if your target browser versions have implemented it.

removeTrack()

RTCPeerConnection.removeTrack() method tells the local end of the connection to stop sending media from the specified track, without actually removing the corresponding RTCRtpSender from the list of senders as reported by RTCPeerConnection.getSenders() .

restartIce()

WebRTC API's RTCPeerConnection interface offers the restartIce() method to allow a web application to easily request that ICE candidate gathering be redone on both ends of the connection.

setConfiguration()

RTCPeerConnection.setConfiguration() method sets the current configuration of the RTCPeerConnection based on the values included in the specified RTCConfiguration object. This lets you change the ICE servers used by the connection and which transport policies to use.

setIdentityProvider()

RTCPeerConnection.setIdentityProvider() method sets the Identity Provider (IdP) to the triplet given in parameter: its name, the protocol used to communicate with it (optional) and an optional username. The IdP will be used only when an assertion is needed.

setLocalDescription()

RTCPeerConnection 方法 setLocalDescription() changes the local description associated with the connection. This description specifies the properties of the local end of the connection, including the media format.

setRemoteDescription()

RTCPeerConnection 方法 setRemoteDescription() sets the specified session description as the remote peer's current offer or answer. The description specifies the properties of the remote end of the connection, including the media format.

Obsolete method

The following method was obsoleted long ago and was never implemented in all major browsers.

也可用作 onaddstream event handler property.

常量

RTCBundlePolicy enum

RTCBundlePolicy enum defines string constants which are used to request a specific policy for gathering ICE candidates if the remote peer isn't "BUNDLE-aware" (compatible with the SDP BUNDLE standard for bundling multiple media streams on a single transport link). All browser implementations are BUNDLE-aware.

If the remote endpoint is BUNDLE-aware, all media tracks and data channels are bundled onto a single transport at the completion of negotiation, regardless of policy used, and any superfluous transports that were created initially are closed at that point.

注意： In technical terms, a BUNDLE lets all media flow between two peers flow across a single 5-tuple ; that is, from a single IP and port on one peer to a single IP and port on the other peer, using the same transport protocol.

常量	描述
"balanced"	The ICE agent initially creates one RTCDtlsTransport for each type of content added: audio, video, and data channels. If the remote endpoint is not BUNDLE-aware, then each of these DTLS transports then handles all the communication for one type of data.
"max-compat"	The ICE agent initially creates one RTCDtlsTransport per media track and a separate one for data channels. If the remote endpoint is not BUNDLE-aware, everything is negotiated on these separate DTLS transports.
"max-bundle"	The ICE agent initially creates only a single RTCDtlsTransport to carry all of the RTCPeerConnection 's data. If the remote endpoint is not BUNDLE-aware, then only a single track will be negotiated and the rest ignored.

RTCIceConnectionState enum

RTCIceConnectionState enum defines the string constants used to describe the current state of the ICE agent and its connection to the ICE server (that is, the STUN or TURN server).

常量	描述
"new"	The ICE agent is gathering addresses or is waiting to be given remote candidates through calls to RTCPeerConnection.addIceCandidate() (or both).
"checking"	The ICE agent has been given one or more remote candidates and is checking pairs of local and remote candidates against one another to try to find a compatible match, but has not yet found a pair which will allow the peer connection to be made. It's possible that gathering of candidates is also still underway.
"connected"	A usable pairing of local and remote candidates has been found for all components of the connection, and the connection has been established. It's possible that gathering is still underway, and it's also possible that the ICE agent is still checking candidates against one another looking for a better connection to use.
"completed"	The ICE agent has finished gathering candidates, has checked all pairs against one another, and has found a connection for all components.
"failed"	The ICE candidate has checked all candidates pairs against one another and has failed to find compatible matches for all components of the connection. It is, however, possible that the ICE agent did find compatible connections for some components.
"disconnected"	Checks to ensure that components are still connected failed for at least one component of the RTCPeerConnection . This is a less stringent test than "failed" and may trigger intermittently and resolve just as spontaneously on less reliable networks, or during temporary disconnections. When the problem resolves, the connection may return to the "connected" 状态。
"closed"	The ICE agent for this RTCPeerConnection has shut down and is no longer handling requests.

RTCIceGatheringState enum

RTCIceGatheringState enum defines string constants which reflect the current status of ICE gathering, as returned using the RTCPeerConnection.iceGatheringState property. You can detect when this value changes by watching for an event of type icegatheringstatechange .

常量	描述
"new"	The peer connection was just created and hasn't done any networking yet.
"gathering"	The ICE agent is in the process of gathering candidates for the connection.
"complete"	The ICE agent has finished gathering candidates. If something happens that requires collecting new candidates, such as a new interface being added or the addition of a new ICE server, the state will revert to "gathering" to gather those candidates.

RTCIceTransportPolicy enum

RTCIceTransportPolicy enum defines string constants which can be used to limit the transport policies of the ICE candidates to be considered during the connection process.

常量	描述
"all"	All ICE candidates will be considered.
"public"	Only ICE candidates with public IP addresses will be considered. Removed from the specification's May 13, 2016 working draft.
"relay"	Only ICE candidates whose IP addresses are being relayed, such as those being passed through a TURN server, will be considered.

RTCPeerConnectionState enum

RTCPeerConnectionState enum defines string constants which describe states in which the RTCPeerConnection may be. These values are returned by the connectionState property. This state essentially represents the aggregate state of all ICE transports (which are of type RTCIceTransport or RTCDtlsTransport ) being used by the connection.

常量	描述
"new"	At least one of the connection's ICE transports ( RTCIceTransport s or RTCDtlsTransport s) are in the "new" state, and none of them are in one of the following states: "connecting" , "checking" , "failed" ，或 "disconnected" , or all of the connection's transports are in the "closed" 状态。
"connecting"	One or more of the ICE transports are currently in the process of establishing a connection; that is, their RTCIceConnectionState 是 "checking" or "connected" , and no transports are in the "failed" 状态。 <<< Make this a link once I know where that will be documented
"connected"	Every ICE transport used by the connection is either in use (state "connected" or "completed" ) or is closed (state "closed" ); in addition, at least one transport is either "connected" or "completed" .
"disconnected"	At least one of the ICE transports for the connection is in the "disconnected" state and none of the other transports are in the state "failed" , "connecting" ，或 "checking" .
"failed"	One or more of the ICE transports on the connection is in the "failed" 状态。
"closed"	RTCPeerConnection is closed. This value was in the RTCSignalingState enum (and therefore found by reading the value of the signalingState ) property until the May 13, 2016 draft of the specification.

RTCRtcpMuxPolicy enum

RTCRtcpMuxPolicy enum defines string constants which specify what ICE candidates are gathered to support non-multiplexed RTCP. <<<add a link to info about multiplexed RTCP.

常量	描述
"negotiate"	Instructs the ICE agent to gather both RTP and RTCP candidates. If the remote peer can multiplex RTCP, then RTCP candidates are multiplexed atop the corresponding RTP candidates. Otherwise, both the RTP and RTCP candidates are returned, separately.
"require"	Tells the ICE agent to gather ICE candidates for only RTP, and to multiplex RTCP atop them. If the remote peer doesn't support RTCP multiplexing, then session negotiation fails.

RTCSignalingState enum

RTCSignalingState enum specifies the possible values of RTCPeerConnection.signalingState , which indicates where in the process of signaling the exchange of offer and answer the connection currently is.

常量	描述
"stable"	There is no ongoing exchange of offer and answer underway. This may mean that the RTCPeerConnection object is new, in which case both the localDescription and remoteDescription are null ; it may also mean that negotiation is complete and a connection has been established.
"have-local-offer"	The local peer has called RTCPeerConnection.setLocalDescription() , passing in SDP representing an offer (usually created by calling RTCPeerConnection.createOffer() ), and the offer has been applied successfully.
"have-remote-offer"	The remote peer has created an offer and used the signaling server to deliver it to the local peer, which has set the offer as the remote description by calling RTCPeerConnection.setRemoteDescription() .
"have-local-pranswer"	The offer sent by the remote peer has been applied and an answer has been created (usually by calling RTCPeerConnection.createAnswer() ) and applied by calling RTCPeerConnection.setLocalDescription() . This provisional answer describes the supported media formats and so forth, but may not have a complete set of ICE candidates included. Further candidates will be delivered separately later.
"have-remote-pranswer"	A provisional answer has been received and successfully applied in response to an offer previously sent and established by calling setLocalDescription() .
"closed"	The connection is closed. 注意： This value moved into the RTCPeerConnectionState enum in the May 13, 2016 draft of the specification, as it reflects the state of the RTCPeerConnection , not the signaling connection. You now detect a closed connection by checking for connectionState 到 "closed" 代替。
