Hi Team,
I m trying to publish a screen-cast to the conference, where I have already published the local stream. It happens randomly but frequently.
The Error is thrown by OWT.js
Here is my code:-
shareScreenStream(userEmail, roomId) {
let screenStream;
let mediaScreenStream;
// audioConstraintsForScreen
let audioConstraints = new Owt.Base.AudioTrackConstraints(Owt.Base.AudioSourceInfo.SCREENCAST);
// videoConstraintsForScreen
let videoConstraints = new Owt.Base.VideoTrackConstraints(Owt.Base.VideoSourceInfo.SCREENCAST);
Owt.Base.MediaStreamFactory.createMediaStream(new Owt.Base.StreamConstraints(audioConstraints, videoConstraints)).then(stream => {
mediaScreenStream = stream;
$('#local').srcObject = mediaScreenStream;
var streamAttribute = {};
streamAttribute.userName = userEmail;
streamAttribute.room = roomId;
streamAttribute.isScreen = true;
screenStream = new Owt.Base.LocalStream(mediaScreenStream, new Owt.Base.StreamSourceInfo('screen-cast', 'screen-cast'), streamAttribute);
this.confrence.publish(screenStream).then(publication => {
//let operation = [{ op: 'replace',path: '/info/layout',value: this.screenShareLayout}];
let operation = [{ op: 'add',path: '/info/inViews',value: 'common' }];
OWT_REST.API.updateStream(roomId, publication.id, operation, function(successResp) {
console.log("Stream Added to Mix Stream");
}, function(status, error) {
console.log("Cannot Add Stream to Mix Stream", status, error);
});
stream.getVideoTracks()[0].onended = function() {
stopScreenShare();
};
publication.addEventListener('error', (err) => {
console.log('Publication error: ' + err.error.message);
});
publication.addEventListener('ended', (err) => {
stopScreenShare();
});
});
}, error => {
console.log("Error Acessing Screen Media:"+error);
});
}
I have already published the local stream to conference.
confrence.join(token).then(resp => {
let connectorId = resp.self.id;
// audioConstraintsForMic
let audioConstraints = new Owt.Base.AudioTrackConstraints(Owt.Base.AudioSourceInfo.MIC);
// videoConstraintsForCamera
let videoConstraints = new Owt.Base.VideoTrackConstraints(Owt.Base.VideoSourceInfo.CAMERA);
let mediaStream;
/* initialise the stream constraints */
Owt.Base.MediaStreamFactory.createMediaStream(new Owt.Base.StreamConstraints(audioConstraints, videoConstraints)).then(localSystemStream => {
let publishOption;
if (simulcast) {
publishOption = {video: [
{rid: 'q', active: true, scaleResolutionDownBy: 4.0},
{rid: 'h', active: true, scaleResolutionDownBy: 2.0},
{rid: 'f', active: true}
]};
}
mediaStream = localSystemStream;
let localStream = new Owt.Base.LocalStream(
mediaStream, new Owt.Base.StreamSourceInfo('mic', 'camera'));
console.log("Appending Local stream to video object");
document.getElementById(videoTagId).srcObject = localSystemStream;
confrence.publish(localStream, publishOption).then(publication => {
//publicationGlobal = publication;
// inform confrence room to accomodate new stream
let operation = [{ op: 'add',path: '/info/inViews',value: 'common' }];
OWT_REST.API.updateStream(roomId, publication.id, operation, function(successResp) {
console.log("Stream Added to Mix Stream");
}, function(status, error) {
console.log("Cannot Add Stream to Mix Stream", status, error);
});
publication.addEventListener('error', (err) => {
console.log('Publication error: ' + err.error.message);
});
});
}, err => {
console.error('Failed to create Local MediaStream, ' + err.message);
conference.leave();
});
The error is :
Please suggest what to do?
