RTCRtpReceiver - Web APIs 编辑

The RTCRtpReceiver interface of the WebRTC API manages the reception and decoding of data for a MediaStreamTrack on an RTCPeerConnection.

Properties

RTCRtpReceiver.track Read only: Returns the MediaStreamTrack associated with the current RTCRtpReceiver instance.
RTCRtpReceiver.transport Read only: Returns the RTCDtlsTransport instance over which the media for the receiver's track is received.

rtcpTransport: This property has been removed; the RTP and RTCP transports have been combined into a single transport. Use the transport property instead.

RTCRtpReceiver.getContributingSources(): Returns an array of RTCRtpContributingSource instances for each unique CSRC (contributing source) identifier received by the current RTCRtpReceiver in the last ten seconds.
RTCRtpReceiver.getParameters(): Returns an RTCRtpParameters object which contains information about how the RTC data is to be decoded.
RTCRtpReceiver.getStats(): Returns a Promise whose fulfillment handler receives a RTCStatsReport which contains statistics about the incoming streams and their dependencies.
RTCRtpReceiver.getSynchronizationSources(): Returns an array including one RTCRtpSynchronizationSource instance for each unique SSRC (synchronization source) identifier received by the current RTCRtpReceiver in the last ten seconds.

RTCRtpReceiver.getCapabilities(): Returns the most optimistic view of the capabilities of the system for receiving media of the given kind.
