RTCRtpSender: transport property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
Please help us by answering a few questions.
The read-only transport property of an
RTCRtpSender object provides the RTCDtlsTransport object
used to interact with the underlying transport over which the sender is exchanging
Real-time Transport Control Protocol (RTCP) packets.
This transport is responsible for receiving the data for the media on the sender's
track.
Value
An RTCDtlsTransport object representing the underlying transport being
used by the sender to exchange packets with the remote peer, or null if the
sender isn't yet connected to a transport.
Description
When the RTCRtpSender is first created, the value of
transport is null. This is replaced with an
RTCDtlsTransport once the sender's transport has been established.
Note that when bundling is in effect—that is, when the RTCPeerConnection
was created with a configuration object whose bundlePolicy is max-compat
or max-bundle—multiple senders 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.
