RTCPeerConnection

RTCPeerConnection 인터페이스는 로컬 컴퓨터와 원격 피어 간의 WebRTC 연결을 담당하며 원격 피어에 연결하기 위한 메서드들을 제공하고, 연결을 유지하고 연결 상태를 모니터링하며 더 이상 연결이 필요하지 않을 경우 연결을 종료합니다.

pendingLocalDescription Read only [Translate]

The read-only property RTCPeerConnection.pendingLocalDescription returns an RTCSessionDescription object describing a pending configuration change for the local end of the connection. This does not describe the connection as it currently stands, but as it may exist in the near future. Use RTCPeerConnection.currentLocalDescription or RTCPeerConnection.localDescription to get the current state of the endpoint. For details on the difference, see Pending and current descriptions in WebRTC connectivity.

pendingRemoteDescription Read only [Translate]

The read-only property RTCPeerConnection.pendingRemoteDescription returns an RTCSessionDescription object describing a pending configuration change for the remote end of the connection. This does not describe the connection as it currently stands, but as it may exist in the near future. Use RTCPeerConnection.currentRemoteDescription or RTCPeerConnection.remoteDescription to get the current session description for the remote endpoint. For details on the difference, see Pending and current descriptions in WebRTC connectivity.

remoteDescription Read only [Translate]

See Signaling in Lifetime of a WebRTC session for more details about the signaling process.

이벤트 핸들러

Also inherits 이벤트 핸들러 from: EventTarget

onaddstream [Translate]

The RTCPeerConnection.onaddstream event handler is a property containing the code to execute when the addstream event, of type MediaStreamEvent, is received by this RTCPeerConnection. Such an event is sent when a MediaStream is added to this connection by the remote peer. The event is sent immediately after the call setRemoteDescription() and doesn't wait for the result of the SDP negotiation.

onconnectionstatechange

RTCPeerConnection.onconnectionstatechange 속성에 RTCPeerConnection 인스턴스에서 발생하는 connectionstatechange 이벤트를 처리하기 위해 호출되는 EventHandler를 정의하게됩니다. 이 이벤트는  연결의 상태 집합체가 변할 때마다 발생합니다. 이 상태 집합체는 연결에 의해 사용되는 각각의 네트워크 전송 상태들의 묶음입니다.

ondatachannel

RTCPeerConnection.ondatachannel 속성은 RTCPeerConnection에서 발생하는 datachannel 이벤트에 의해 호출되는 EventHandler입니다. 이 속성에는 함수를 정의하게됩니다. RTCDataChannelEvent의 한 종류인 이 이벤트는 원격 유저가 createDataChannel()를 호출해서 연결에 RTCDataChannel가 추가되었을 때, 전달됩니다.

onicecandidate

 RTCPeerConnection 속성의 onicecandidate 는 RTCPeerConnection 인스턴스에서 icecandidate 이벤트 발생시에 호출 하려는 함수를 지정합니다. 이 이벤트는 로컬 ICE 에이전트가 signaling 서버를 통해 원격 피어에게 메세지를 전달 할 필요가 있을때 마다 발생합니다. 그리고 ICE 에이전트가 signaling에 사용되는 기술에 대한 구체사항을 모르더라도 원격 피어와의 네고시에이션을 수행하도록 도와줍니다. 어떤 메세징 기술을 선택하던간에, 이 메소드를 사용해서 원격 피어에 ICE candidate를 전달하는 과정을 간단하게 구현 할 수 있습니다.

oniceconnectionstatechange [Translate]

The RTCPeerConnection.oniceconnectionstatechange property is an event handler which specifies a function to be called when the iceconnectionstatechange event is fired on an RTCPeerConnection instance. This happens when the state of the connection's ICE agent, as represented by the iceConnectionState property, changes.

onicegatheringstatechange

RTCPeerConnection.onicegatheringstatechange속성은 icegatheringstatechange 이벤트가 RTCPeerConnection에 전달될 때 호출이되는 함수를 정의하는 EventHandler입니다. 이이벤트는 ICE 에이전트가 ICE candidate를 수집을 하는지의 여부를 알려주는 ICE 수집 상태가 변하면 발생합니다. 하지만, ICE 수집 상태를 모니터링 해야하는 특별한 이유가 없으면 이 이벤트를 감시 할 필요는 없습니다.

onidentityresult

RTCPeerConnection.onidentityresult 이벤트 핸들러는 RTCPeerConnection가 RTCIdentityEvent 타입의 identityresult 이벤트를 수신하게되면 실행되는 코드를 담고 있는 속성입니다. 이러한 이벤트는 getIdentityAssertion() 혹은 offer 혹은 answer를 생성하는 과정에 의해 식별인자 주장이 생성되면 전송됩니다.

onidpassertionerror [Translate]

The RTCPeerConnection.onidpassertionerror event handler is a property containing the code to execute whent the idpassertionerror event, of type RTCIdentityErrorEvent, is received by this RTCPeerConnection. Such an event is sent when the associated identity provider (IdP) encounters an error while generating an identity assertion.

onidpvalidationerror [Translate]

The RTCPeerConnection.onidpvalidationerror event handler is a property containing the code to execute whent the idpvalidationerror event, of type RTCIdentityErrorEvent, is received by this RTCPeerConnection. Such an event is sent when the associated identity provider (IdP) encounters an error while validating an identity assertion.

onnegotiationneeded [Translate]

The RTCPeerConnection interface's onnegotiationneeded property is an EventListener which specifies a function which is called to handle the negotiationneeded event when it occurs on an RTCPeerConnection instance. This event is fired when a change has occurred which requires session negotiation. This negotiation should be carried out as the offerer, because some session changes cannot be negotiated as the answerer.

onpeeridentity [Translate]

The RTCPeerConnection.onpeeridentity event handler is a property containing the code to execute whent the peeridentity event, of type Event, is received by this RTCPeerConnection. Such an event is sent when an identity assertion, received from a peer, has been successfully validated.

Methods

Also inherits methods from: EventTarget

addIceCandidate()

RTCPeerConnection을 사용하는 웹이나 앱이 신규 ICE candidate를 signaling 채널을 통해 원격 유저로부터 수신하게되면, RTCPeerConnection.addIceCandidate()를 호출해서 브라우저의 ICE 에이전트에게 새로 수신한 candidate를 전달합니다.

addStream() [Translate]

The obsolete RTCPeerConnection method 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()

RTCPeerConnection의 메소드인 addTrack()은 다른 유저에게 전송될 트랙들의 묶음에 신규 미디어 트랙을 추가합니다.

close()

RTCPeerConnection.close() 메소드로 피어 연결을 종료합니다.

createAnswer()

RTCPeerConnection 인터페이스의 createAnswer() 메소드는 WebRTC 연결 중 발생하는 offer/answer 네고시에이션에서 원격 유저로부터 받은 offer에 대한 SDP answer를 생성합니다. 이 answer는 세션이 이미 부착된 미디어, 브라우저에서 지원하는 코덱 및 옵션, 그리고 이미 수집된 ICE candidate에 대한 정보를 담고 잇습니다. Answer는 반환 된 Promise에 전달되고, 그 다음에는 네고시에이션 과정을 계속 진행하기 위해서 offer의 소스에게 전달되야합니다.

createDataChannel()

RTCPeerConnection 인터페이스의 createDataChannel() 메소드는 어떤 형식의 데이터든 송신 할 수 있도록 원격 유저와 연결하는 신규 채널을 생성합니다.

getReceivers()

RTCPeerConnection.getReceivers() 메소드는 RTCRtpReceiver 객체의 배열을 반환합니다. 이 배열의 각 요소들은 RTP 리시버를 나타냅니다. 각각의 RTP 리시버는 RTCPeerConnection에 대한 MediaStreamTrack의 데이터를 수신하고 디코딩 합니다.

getSenders()

RTCPeerConnection의 getSenders() 메소드는 RTCRtpSender 객체의 배열을 반환합니다. 배열의 각 객체는 하나의 트랙의 데이터의 송신을 담당하는 RTP sender를 나타냅니다.

getStats() [Translate]

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

getStreamById() [Translate]

The RTCPeerConnection.getStreamById() method returns the 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 인터페이스의 getTransceivers() 메소드는 연결에서 데이터 전송 및 수신에 사용되는 RTCRtpTransceiver 객체의 리스트를 반환합니다.

removeStream() [Translate]

The 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() 메소드는 RTCPeerConnection.getSenders()에 의해 보고된 발신자 목록에서 해당 RTCRtpSender를 실제로 제거하지 않은채, 지정한 트랙에서 미디어 전송을 중단하도록 연결의 로컬엔드에 알려줍니다.

restartIce()

WebRTC API의 RTCPeerConnection 인터페이스에서는 restartIce() 메소드를 제공해서 연결의 양쪽에서 ICE candidate의 재수집 요청을 간단하게 할 수 있게 만들어줍니다.

setConfiguration()

RTCPeerConnection.setConfiguration() 메소드는 RTCConfiguration객체에 명시한 값을 가지고 RTCPeerConnection의 현재 설정을 지정합니다. 이 메소드를 사용해서 연결에서 사용되는 ICE 서버와 전송 정책을 변경 할 수 있습니다.

setIdentityProvider()

RTCPeerConnection.setIdentityProvider() 메소드는 이름, 통신에 사용된 프로토콜 (옵션), 유저 이름 (옵션)으로 구성된 세 가지 매개변수에 식별 제공자 (Identity Provider, IdP)를 지정합니다. IdP는 주장 (assertion)이 필요한 순간에만 사용 될 것입니다.

setLocalDescription()

RTCPeerConnection.setLocalDescription() 메소드는 연결 인터페이스와 관련이 있는 로컬 설명 (local description)을 변경합니다. 로컬 설명은 미디어 형식을 포함하는 연결의 로컬 엔드에 대한 속성을 명시합니다.

The RTCPeerConnection method 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.

사용되지 않는 메서드

다음 메서드는 오래 전부터 사용되지 않았으며 모든 주요 브라우저에서 구현되지 않았습니다.

RTCPeerConnection.createDTMFSender()

특정 MediaStreamTrack와 관련된 신규 RTCDTMFSender를 생성합니다. RTCDTMFSender는 연결을 통해 DTMF 전화 신호를 보낼 수 있습니다.

ICE candidate를 수집하는 과정에서 에러가 발생하면 연결에 RTCPeerConnectionIceErrorEvent 에러 타입을 보냅니다. 이는 또한, onicecandidateerror 이벤트 핸들러 속성을 통해 사용이 가능합니다.

iceconnectionstatechange

연결이 끊기는 상황과 같이 ICE 연결의 상태가 변하게되면 RTCPeerConnection에 전달합니다. 이는 또한, oniceconnectionstatechange 이벤트 핸들러 속성을 통해 사용이 가능합니다.

icegatheringstatechange

iceGatheringState에 의해 반영되는 ICE 계층의 수집 상태가 변하면, RTCPeerConnection에 전달합니다. 계층의 수집 상태는 ICE 네고시에이션이 아직 시작을 안했거나 (new), 시작하고 candidate를 수집하는 중이거나 (gathering), 혹은 수집이 완료 (complete)된 상태로 나눠집니다. 이는 또한, onicegatheringstatechange 이벤트 핸들러 속성을 통해 사용이 가능합니다.

isolationchange

연결과 관련이 있는 하나의 MediaStreamTrack 객체가 있는 isolated 속성의 값이 변하면, RTCPeerConnection에 전달합니다. 만약 미디어 컨텐츠가 인증이 되어있지 않거나, 트랙이 cross-origin source (CORS)에서 오는 것이라면 트랙의 상태는 isolated이 됩니다. 이는 또한, onisolationchange 이벤트 핸들러 속성을 통해 사용이 가능합니다.

negotiationneeded

ICE 연결의 네고시에이션 혹은 네고시에이션을 다시 수행해야 할 때, RTCPeerConnection에 전달됩니다. 이는 연결이 처음 생성되는 순간뿐만아니라 네트워크 조건이 바뀌게 되면 발생합니다. 리시버는 offer를 생성하고, 이를 다른 피어에 전달하기위해 응답해야합니다. 이는 또한, onnegotiationneeded 이벤트 핸들러 속성을 통해 사용이 가능합니다.

signalingstatechange

연결의 ICE 신호 상태가 변경되면 signalingstatechange이벤트를 RTCPeerConnection에 전달합니다. 이는 또한, onsignalingstatechange 이벤트 핸들러 속성을 통해 사용이 가능합니다.

statsended

모니터링이 되던 statistics 객체가 삭제되면, statsended이벤트를 전달합니다. RTCStatsEvent는 삭제된 객체의 마지막 리포트를 포함합니다. 마지막 리포트를 전달받고나서 여러개의 객체가 삭제되었다면, 여러 객체에 대한 마지막 리포트를 포함합니다. 예를 들어 연결이 종료되거나 삭제되면, statistics 객체는 삭제됩니다. 

The statsended event is sent when a statistics object being monitored is deleted. The RTCStatsEvent includes the final report on the deleted object (or objects, if multiple objects have been deleted since the last report was delivered). A statistics object is deleted, for example, when the connection is closed and deleted.
Available as the onstatsended event handler property.

track

연결을 구성하고 있는 RTCRtpReceiver 인스턴스들 중 하나에 신규 트랙이 추가된 후에, track이벤트를 보냅니다. 이는 또한, ontrack 이벤트 핸들러 속성을 통해 사용이 가능합니다.

Sent when a new MediaStream has been added to the connection. Instead of watching for this obsolete event, you should watch each for track events; one is sent for each MediaStreamTrack added to the connection.
Available as the onaddstream event handler property.

identityresult

In old versions of the WebRTC specification, this event was used to indicate that an identity assertion is available. Now, you should instead wait for a the promise returned by peerIdentity to resolve with an identity.
Also available using the onidentityresult event handler property.

idpassertionerror

In old versions of the WebRTC specification, this event was used to indicate that an error occurred while attempting to generate an identity assertion. Now, you should instead wait for a the promise returned by peerIdentity to be rejected with an error.
Also available as the onidpinsertionerror event handler property.

idpvalidationerror

Also available using the onpeerdentity event handler property.

peeridentity

In old versions of the WebRTC specification, this event was used to deliver a received identity. Now, you should instead wait for a the promise returned by peerIdentity to resolve with an identity.

removestream

Sent to the RTCPeerConnection when a MediaStream is removed from the connection. Instead of watching for this obsolete event, you should watch each stream for removetrack events on each stream within the RTCPeerConnection.

상수

RTCBundlePolicy 열거체

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

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

상수명	설명
"balanced"	On BUNDLE-aware connections, the ICE agent should gather candidates for all of the media types in use (audio, video, and data). Otherwise, the ICE agent should only negotiate one audio and video track on separate transports.
"max-compat"	The ICE agent should gather candidates for each track, using separate transports to negotiate all media tracks for connections which aren't BUNDLE-compatible.
"max-bundle"	The ICE agent should gather candidates for just one track. If the connection isn't BUNDLE-compatible, then the ICE agent should negotiate just one media track.

RTCIceConnectionState 열거체

The 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).

상수명	설명
"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" state.
"closed"	The ICE agent for this RTCPeerConnection has shut down and is no longer handling requests.

RTCIceGatheringState enum

RTCPeerConnection.iceGatheringState 속성을 사용하게되면 반환되는 RTCIceGatheringState enum은 현재의 ICE 수집 상태를 반영하여 알려주는 문자열 상수입니다. icegatheringstatechange 타입의 이벤트를 감시해서 이 값이 언제 변하는지 확인 할 수 있습니다.

상수명	설명
"new"	피어 연결이 새로 생성되었지만, 아직 네트워킹은 시작되지 않은 상태
"gathering"	ICE 에이전트가 연결을 위한 ICE candidate를 수집하는 과정에 있음을 알려주는 상태
"complete"	ICE 에이전트가 candidate 수집을 완료한 상태. 새로운 인터페이스가 추가되거나, 신규 ICE 서버가 추가와 같이 신규 ICE candidate를 수집해야하는 상황이 오면, 상태가 complete에서 gathering으로 다시 바뀝니다.

RTCIceTransportPolicy enum

The 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.

상수명	설명
"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 enum은 RTCPeerConnection이 존재 할 수 도있는 상태에 대해 알려주는 문자열 상수를 정의합니다. 이 값들은 {domxref("RTCPeerConnection.connectionState", "connectionState")}} 속성에 의해 반홥됩니다. 근본적으로 이 상태는 연결에 의해 사용되는 모든 ICE 전송 (RTCIceTransport 혹은 RTCDtlsTransport의 타입)의 상태 집합을 나타냅니다. 

상수명	설명
"new"	연결의 ICE 전송 중 적어도 한 개가 새로 만들어진 "new" 상태이고,  그 외의 나머지는 다음의 상태 중 하나가 아니여야 합니다: "connecting", "checking", "failed", 혹은 "disconnected", 혹은  모든 연결의 전송이 끝났다는 "closed"상태.
"connecting"	하나 혹은 여러개의 ICE 전송이 현재 연결을 구성하는 중에 있음을 알려주는 값. 이는 RTCIceConnectionState가 "checking" 혹은 "connected"이며, 그 어떤 전송도 "failed"상태가 아니여야합니다. <<< Make this a link once I know where that will be documented
"connected"	연결에 의해 사용되는 모든 ICE 전송이 사용 중 ("connected" 혹은 "completed")이거나, 종료된 상태입니다. 추가적으로 최소 하나의 전송이 "connected" 혹은 "completed"입니다.
"disconnected"	연결에 대한 최소 한 개의 ICE 전송이 "disconnected"상태이고, 그 외의 다른 전송 상태는 "failed", "connecting", 혹은 "checking"이 아님을 알려주는 값.
"failed"	연결에 대한 하나 혹은 여러개의 ICE 전송이 "failed"상태임을 알려주는 값.
"closed"	RTCPeerConnection 개통되지 않음을 알려주는 값. 2016년 5월 13일에 작성된 명세서의 초안에 따르면, 이 값은 RTCPeerConnectionState enum 안에 존재했었습니다. 따라서, signalingState의 값을 통해 찾을 수 있습니다.

RTCRtcpMuxPolicy enum

The 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.

상수명	설명
"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

The 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.

상수명	설명
"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. 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 to be "closed" instead.
