            Bug ID: 201640
           Summary: No candidates when trying to subscribe to a media flow
                    without publishing
           Product: WebKit
           Version: Safari 12
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org

Summary:

In a WebRTC conference, we should have the possibility to publish or subscribe media flows we want.
When using Safari, it is not possible to subscribe to WebRTC media flows without requesting users to share his camera/micro (getUserMedia)
No candidates are retrieved from the peerConnection 

Steps to Reproduce:

You can use our demo links that use our apiRTC library:
1 - open the link in Chrome browser to publish a media flow in conference :
https://www.apizee.com/inte/testSafari/conferencing_pubOnly/
2 - open the link in Safari to subscribe the media flow from (1) in conference :
https://www.apizee.com/inte/testSafari/conferencing_subOnly/

Expected Results:

We should have the subscribed flow displayed on Safari


Actual Results:

Safari doesn't retrieve any candidate : check the log in console :
"Warning, no candidate where retrieved for this call on client"

If we call getUserMedia and user accept the GUM request, we can subscribe ... but it shouldn't be necessary to share its camera to subscribe to a media flow

Note : it is working with Chrome / Firefox 


Version/Build:

Safari on MacOs - Version 12.0 (14606.1.36.1.9)
