RTCRtpSender interface provides the ability to control and obtain details about how a particular MediaStreamTrack is encoded and sent to a remote peer. With it, you can configure the encoding used for the corresponding track, get information about the device's media capabilities, and so forth. You can also obtain access to an RTCDTMFSender which can be used to send DTMF codes (to simulate the user pressing buttons on a telephone's dial pad) to the remote peer.

特性

RTCRtpSender.dtmf 只读

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

RTCRtpSender.track 只读

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

RTCRtpSender.transport 只读

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.

过时特性

rtcpTransport

This property has been removed; the RTP and RTCP transports have been combined into a single transport. Use the transport 特性代替。

方法

RTCRtpSender.getParameters()

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

RTCRtpSender.getStats()

返回 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()

设置 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.

静态方法

RTCRtpSender.getCapabilities()

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