Web/API/RTCRtpReceiver/transport

The read-only transport property of an RTCRtpReceiver object provides the RTCDtlsTransport object used to interact with the underlying transport over which the receiver is exchanging Real-time Transport Control Protocol (RTCP) packets.

This transport is responsible for receiving the data for the media on the receiver's track.

Syntax

let transport = rtcRtpReceiver.transport;

Value

An RTCDtlsTransport object representing the underlying transport being used by the receiver to exchange packets with the remote peer, or null if the receiver isn't yet connected to a transport.

Description

When the RTCRtpReceiver is first created, the value of transport is null. This is replaced with an RTCDtlsTransport once the receiver's transport has been established.

Note that when bundling is in effect—that is, when the RTCPeerConnection was created with an RTCConfiguration object whose bundlePolicy is max-compat or max-bundle—multiple receivers may be sharing the same transport; in this case, all of them are using the same connection to transmit and/or receive RTP and RTCP packets.
