Can you subscribe to a WebRTC stream with both mediaConstraints, audio and video, set as false?



Can you subscribe to a WebRTC stream with both mediaConstraints, audio and video, set as false? When one subscribes to a stream with both set as false, and later an attempt is made to unmute the subscribed user, then it gives error that the audio stream is undefined. It kind of makes sense that if neither audio nor video is subscribed then what is getting subscribed. But a validation from a WebRTC/Kurento expert will help.




let participant = participants[senderid];

var options = {
remoteVideo: videoElement,
mediaConstraints: {audio:false,video:false},
participantid: senderid,
onicecandidate:participant.onIceCandidate.bind(participant)
};

participant.rtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerRecvonly(options, function (error) {
if (error) {
return console.error(error);
}
this.generateOffer(participant.offerToReceiveVideo.bind(participant));

});
this.socket.on('userStatusChanged',(senderid)=>{
let participant = participants[senderid];
// Here I want to enable the audio for this sender.
})


// Note: - I tried the below case. But getting undefined in remoteStream.
// let remoteStream = participant.rtcPeer.peerConnection.getRemoteStreams()[0];

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
