RTCRtpSender

Properties

RTCRtpSender.dtmf Read only

An RTCDTMFSender which can be used to send DTMF tones using telephone-event payloads on the RTP session represented by the RTCRtpSender object. If null, the track and/or the connection doesn't support DTMF. Only audio tracks can support DTMF.

RTCRtpSender.track Read only

The MediaStreamTrack which is being handled by the RTCRtpSender. If track is null, the RTCRtpSender doesn't transmit anything.

RTCRtpSender.transport Read only

The RTCDtlsTransport over which the sender is exchanging the RTP and RTCP packets used to manage transmission of media and control data. This value is null until the transport is established. When bundling is in use, more than transceiver may be sharing the same transport object.

Obsolete properties

rtcpTransport

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

Methods

RTCRtpSender.getParameters()

Returns a RTCRtpParameters object describing the current configuration for the encoding and transmission of media on the track.

RTCRtpSender.getStats()

Returns a Promise which is fulfilled with a RTCStatsReport which provides statistics data for all outbound streams being sent using this RTCRtpSender.

RTCRtpSender.setParameters()

Applies changes to parameters which configure how the track is encoded and transmitted to the remote peer.

RTCRtpSender.setStreams()

Sets the MediaStream(s) associated with the track being transmitted by this sender.

RTCRtpSender.replaceTrack()

Attempts to replace the track currently being sent by the RTCRtpSender with another track, without performing renegotiation. This method can be used, for example, to toggle between the front- and rear-facing cameras on a device.

Static methods

RTCRtpSender.getCapabilities()

Returns an RTCRtpCapabilities object describing the system's capabilities for sending a specified kind of media data.
