RTCPeerConnection: getSenders() method
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.
* Some parts of this feature may have varying levels of support.
The getSenders() method of the RTCPeerConnection interface returns an array of RTCRtpSender objects, each of which represents the RTP sender responsible for transmitting one track's data.
A sender object provides methods and properties for examining and controlling the encoding and transmission of the track's data.
Syntax
getSenders()
Parameters
None.
Return value
An array of RTCRtpSender objects, one for each track on the connection.
The array is empty if there are no RTP senders on the connection.
The order of the returned RTCRtpSender instances is not defined by the specification, and may change from one call to getSenders() to the next.
The array does not include senders associated with transceivers that have been stopped (following offer/answer).
Example
In this example, a setMuting() function is shown.
This function takes as input an RTCPeerConnection, pc, and a Boolean, muting.
The function gets the list of the peer connection's senders and iterates over every sender, setting the corresponding media track's enabled to the inverse of the specified muting.
function setMuting(pc, muting) {
let senderList = pc.getSenders();
senderList.forEach((sender) => {
sender.track.enabled = !muting;
});
}
