Unable to record again after stopping record in Kurento - webrtc

Question

I am working on this Kurento application and there is a strange problem i am facing where once I start recording the video and stop the recording, I cant start another recording again. The event goes to the server but nothing seems to be happening! PFB the code:
room.pipeline.create('WebRtcEndpoint', function (error, outgoingMedia) {
if (error) {
console.error('no participant in room');
// no participants in room yet release pipeline
if (Object.keys(room.participants).length == 0) {
room.pipeline.release();
}
return callback(error);
}
outgoingMedia.setMaxVideoRecvBandwidth(256);
userSession.outgoingMedia = outgoingMedia;
// add ice candidate the get sent before endpoint is established
var iceCandidateQueue = userSession.iceCandidateQueue[socket.id];
if (iceCandidateQueue) {
while (iceCandidateQueue.length) {
var message = iceCandidateQueue.shift();
console.error('user : ' + userSession.id + ' collect candidate for outgoing media');
userSession.outgoingMedia.addIceCandidate(message.candidate);
}
}
userSession.outgoingMedia.on('OnIceCandidate', function (event) {
console.log("generate outgoing candidate : " + userSession.id);
var candidate = kurento.register.complexTypes.IceCandidate(event.candidate);
userSession.sendMessage({
id: 'iceCandidate',
sessionId: userSession.id,
candidate: candidate
});
});
// notify other user that new user is joining
var usersInRoom = room.participants;
var data = {
id: 'newParticipantArrived',
new_user_id: userSession.id,
receiveVid: receiveVid
};
// notify existing user
for (var i in usersInRoom) {
usersInRoom[i].sendMessage(data);
}
var existingUserIds = [];
for (var i in room.participants) {
existingUserIds.push({id: usersInRoom[i].id, receiveVid: usersInRoom[i].receiveVid});
}
// send list of current user in the room to current participant
userSession.sendMessage({
id: 'existingParticipants',
data: existingUserIds,
roomName: room.name,
receiveVid: receiveVid
});
// register user to room
room.participants[userSession.id] = userSession;
var recorderParams = {
mediaProfile: 'WEBM',
uri: "file:///tmp/Room_"+room.name+"_file"+userSession.id +".webm"
};
//make recorder endpoint
room.pipeline.create('RecorderEndpoint', recorderParams, function(error, recorderEndpoint){
userSession.outgoingMedia.recorderEndpoint = recorderEndpoint;
outgoingMedia.connect(recorderEndpoint);
});
On the screen when I click the record button, the function on the server is:
function startRecord(socket) {
console.log("in func");
var userSession = userRegistry.getById(socket.id);
if (!userSession) {
return;
}
var room = rooms[userSession.roomName];
if(!room){
return;
}
var usersInRoom = room.participants;
var data = {
id: 'startRecording'
};
for (var i in usersInRoom) {
console.log("in loop");
var user = usersInRoom[i];
// release viewer from this
user.outgoingMedia.recorderEndpoint.record();
// notify all user in the room
user.sendMessage(data);
console.log(user.id);
}}
The thing is, for the very 1st time, it records properly i.e. file created on server and video&audio recorded properly.
When I press stop to stop recording, the intended effect is seen i.e. recording stops.
NOW, when I press record again, a video file is not made. The event reaches the server properly (console.log says so)
Can anyone help me pls?!
Thanks.
