RTCRtpSender object

Exposes information relating to the RTP sender.

Overview

An RTCRtpSender instance is associated to a sending MediaStreamTrack and provides RTC related methods to it.

Operation

A RTCRtpSender instance is constructed from a MediaStreamTrack object and associated to an RTCDtlsTransport or an RTCSrtpSdesTransport. If an attempt is made to construct an RTCRtpSender object with transport.state or rtcpTransport.state "closed", throw an InvalidStateError exception.

Note  Edge Interop Note: The Microsoft Edge ORTC API implementation requires use of RTP/RTCP multiplexing with RTCDtlsTransport objects. Therefore only a single RTCDtlsTransport instance can be associated to an RTCRtpSender instance. RTP/RTCP non-mux is supported for RTCSrtpSdesTransport objects. Only a single RTCSrtpSdesTransport object is required to handle both RTP and RTCP.
 

Syntax

typedef (RTCDtlsTransport or RTCSrtpSdesTransport) RTCTransport;

[Constructor(MediaStreamTrack track, RTCTransport transport)]
interface RTCRtpSender : RTCStatsProvider {
    readonly    attribute MediaStreamTrack track;
    readonly    attribute RTCTransport     transport;
    void                      setTransport (RTCTransport transport);
    void                      setTrack (MediaStreamTrack track);
    static RTCRtpCapabilities getCapabilities (optional DOMString kind);
    void                      send (RTCRtpParameters parameters);
    void                      stop ();
                attribute EventHandler?    onerror;
};

Members

The RTCRtpSender object has these types of members:

Events
