take the following code: ``` var pc = new RTCPeerConnection(); navigator.mediaDevices.getUserMedia({audio: true}) .then(stream => { pc.addTrack(stream.getAudioTracks()[0], stream); pc.getTransceivers()[0].setDirection("sendonly"); console.log("direction is", pc.getTransceivers()[0].direction); return pc.createOffer(); }) .then(offer => { console.log(offer.sdp); }) ``` setDirection works, the console log shows "direction is sendonly". However, the offer that is created has a a=sendrecv audio mline. Similiarly for making a call on https://webrtc.github.io/samples/src/content/peerconnection/pc1/, calling setDirection and then creating a subsequent offer.
no longer applies presumably due to the switch away from plan-b
