RTCRtpSender

The RTCRtpSender interface provides the ability to control and obtain details about how a particular MediaStreamTrack is encoded and sent to a remote peer.

MDN Reference

Methods

getParameters()

getParameters(): RTCRtpSendParameters;

The getParameters() method of the RTCRtpSender interface returns an object describing the current configuration for how the sender's track will be encoded and transmitted to a remote RTCRtpReceiver.

MDN Reference

Returns

RTCRtpSendParameters


getStats()

getStats(): Promise<RTCStatsReport>;

The RTCRtpSender method getStats() asynchronously requests an RTCStatsReport object which provides statistics about outgoing traffic on the RTCPeerConnection which owns the sender, returning a Promise which is fulfilled when the results are available.

MDN Reference

Returns

Promise<RTCStatsReport>


replaceTrack()

replaceTrack(withTrack): Promise<void>;

The RTCRtpSender method replaceTrack() replaces the track currently being used as the sender's source with a new MediaStreamTrack.

MDN Reference

Parameters

ParameterType
withTrackMediaStreamTrack | null

Returns

Promise<void>


setParameters()

setParameters(parameters, setParameterOptions?): Promise<void>;

The setParameters() method of the RTCRtpSender interface applies changes the configuration of sender's track, which is the MediaStreamTrack for which the RTCRtpSender is responsible.

MDN Reference

Parameters

ParameterType
parametersRTCRtpSendParameters
setParameterOptions?RTCSetParameterOptions

Returns

Promise<void>


setStreams()

setStreams(...streams): void;

The RTCRtpSender method setStreams() associates the sender's track with the specified MediaStream objects.

MDN Reference

Parameters

ParameterType
...streamsMediaStream[]

Returns

void

Properties

dtmf

readonly dtmf: RTCDTMFSender | null;

The read-only dtmf property on the RTCRtpSender interface returns a RTCDTMFSender object which can be used to send DTMF tones over the RTCPeerConnection. See Using DTMF for details on how to make use of the returned RTCDTMFSender object.

MDN Reference


track

readonly track: MediaStreamTrack | null;

The track read-only property of the RTCRtpSender interface returns the MediaStreamTrack which is being handled by the RTCRtpSender.

MDN Reference


transform

transform: RTCRtpScriptTransform | null;

The transform property of the RTCRtpSender object is used to insert a transform stream (TransformStream) running in a worker thread into the sender pipeline. This allows stream transforms to be applied to encoded video and audio frames after they are output by a codec, and before they are sent.

MDN Reference


transport

readonly transport: RTCDtlsTransport | null;

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.
