RTCRtpTransceiver.stop() - Web APIs 编辑

The stop() method in the RTCRtpTransceiver interface permanently stops the transceiver by stopping both the associated RTCRtpSender and RTCRtpReceiver.

Note: Until recently, the stopped property was provided to return true if the connection is stopped. That property has been deprecated and will be removed at some point. Instead, check the value of currentDirection. If it's stopped, the transceiver has been stopped.

This method does nothing if the transceiver is already stopped.

Syntax

RTCRtpTransceiver.stop()

Paramters

None.

Return value

undefined

Exceptions

InvalidStateError

The RTCPeerConnection of which the transceiver is a member is closed.

Usage notes

When you call stop() on a transceiver, the sender immediately stops sending media and each of its RTP streams are closed using the RTCP "BYE" message. The receiver then stops receiving media; the receiver's track is stopped, and the transceiver's direction is changed to stopped, and renegotiation is triggered by sending a negotiationneeded event to the RTCPeerConnection.

The negotiation process causes currentNegotiation to be set to stopped, finally indicating that the transceiver has been fully stopped.

Note: Stopping the transceiver causes a negotiationneeded event to be sent to the transceiver's RTCPeerConnection, so the connection can adapt to the change.
