setDirection

open fun setDirection(rtpTransceiverDirection: RtpTransceiver.RtpTransceiverDirection): Boolean

Sets the preferred direction of this transceiver. An update of directionality does not take effect immediately. Instead, future calls to CreateOffer and CreateAnswer mark the corresponding media descriptions as sendrecv, sendonly, recvonly, or inactive. https://w3c.github.io/webrtc-pc/#dom-rtcrtptransceiver-direction
